Human Body System
To keep your Heart healthy, you should exercise for at least 30 minutes a day. Another way to keep your heart healthy, is to limit or eliminate tobacco usage. The most important way to keep your circulatory system healthy is to maintain a healthy weight.
This system is the system that keeps your blood moving through your body. There are 3 organs in this system.
There are three organs in this system. The Heart, Blood and Blood Vessels.
The Heart is the most recognized organ in this system. Little known to many, blood and blood vessels also are organs.
For starters, this is the system that smoking has the biggest affect on. Smoking leaves a poisonous tar, that prevent any of the lung's cleaning systems from working causing a build-up in cancerous particles in your lungs.
How Can I Keep My Respiratory system Healthy?
This is the system that "powers" you. When you eat or drink, that food travels though this system.
The Digestive System
The Circulatory system is the system that controls and moves the blood around your body.
The Respiratory system delivers oxygen to the cells in your body that constantly need oxygen.
The Circulatory System
The Respiratory System
What is the function of this system?
Organs in the Circulatory System.
How To Keep This System Healthy
In this presentation 5 systems will be showcased. These systems are The Circulatory system, The Respiratory System, The Digestive System, The Nervous System and the Excretory System.
Connections With Other Systems
The circulatory system is connected to every system. Every organ in every system needs blood to work. The body vitally requires this system to work properly or the body will not preform in the desired way.
Two of the most common problems/illnesses with this system is heart failure and blood clot in the blood vessels.
Blood Clots can be fetal, many people have died from blood clots. A blood clot occurs when
the thrombus blocks a section of the
A Blood clot is shown in the diagram above.
Fact: More than 1 million americans have heart attacks per year. A heart attack occurs when blood clots form in many of the arteries leading into the heart. The loss of oxygen to the heart makes the heart cells die and the heart fails.
The heart: the main organ in this system
The heart is the most vital organ in you, do not abuse it!
A heart attack is shown in the diagram above.
What do the organs in this system do?
The heart pumps the Blood around the body. The Blood flows through the Blood vessels to the other organs in the body.
The Blood Vessels take the Blood from the heart to the other organs. When these get clogged, those clogs can be deadly.
Blood is needed by all of the organs in every system. Blood carries oxygen to these organs in the cells.
This system Ingests the food, Digests it, Absorbs the Nutrients and Disposes of the waste.
There are seven organs in the Digestive system. These organs all work together to provide the power you need to preform every day.
Is this system connected to any other?
This system works together with the Circulatory System. the Circulatory System supplies blood to the organs in this system.
What Are The Organs In This System ?
In the mouth there are three
organs, The Teeth (32 small organs), The Tongue and the Salivary Glands.
The teeth break down the food you eat into smaller pieces that your pharynx can handle.
The tongue, pushes food towards the back of the mouth. The tongue also tells the brain if the body should consume that food or not.
The salivary glands produce saliva. This saliva moistens the food so it can pass through the pharynx.
This organ's main job is to protect you from choking. The Pharynx regulates the air and food flow. It also prevents you from breathing and eating at the same time. The Pharynx also directs air into the lungs.
The Esophagus' job
is to carry food from the Pharynx to the Stomach. The muscles in the Esophagus push the food into the stomach.
The Stomach acts as a storage sack for large meals. Your body needs this sack so it has time to digest large meals.
The Small Intestine is where almost all of the nutrients are extracted from the food. When the waste leaves the small intestines over 90% of the nutrients from the food has been absorbed.
Liver & Gallbladder
Bile is produced in the liver and stored in the Gallbladder. Bile helps your food move through the Small Intestine. it acts as a surfactant (lowers surface tension).
The Large Intestine takes any of the remaining water from your food. When the food exits the Large Intestine, almost all of the nutrients and water have been absorbed.
How Can I Keep This System Healthy?
There are four easy ways to keep this system healthy.
Eat More Fruit and Vegetables
When you eat fruits and vegetables, the fiber in these help make the waste from your food the right consistency. It also helps the waste move quicker through your intestines.
Eat In Small Portions, Slowly and Regularly
When you eat too much, it puts a lot of stress on your digestive system.
Food that is well chewed is easier to consume than large mouthfuls. That means it is easy to digest.
Eating regularly prevents you from over eating at meal time. Also, you wont have to be constantly snacking.
When you exercise, all of your muscles get a work out, including the muscles in the digestive system.
Smoking an give you heart burn and can also give you ulcers in your bowels.

ATTENTION: Please note that if a slide does not have an information source, it was pretty general knowledge and I didn't need any help from the internet or a book. But who used books anyway?
It has been brought to my attention that it might have been a little insulting to say that no one used books. Please disregard the statement about books above.
Organs In This System
There are seven organs in this system. These organs all play an essential role in providing oxygen to all of the cells in your body.
What Are The Seven Organs?
The Nose, is the first and primary point of entrance for the air passing into your body. The hairs in your nose, help block dust in the air from entering.
The Pharynx, as said before, functions as an anti-choke mechanism. In this case, the Pharynx, stops you from breathing through your nose and mouth at the same time.
Also known as the "voice box", the Larynx, has three main parts.
This minor organ, closes when you chew or swallow and opens to allow you to talk. This prevents food and water from getting into your lungs.
The Thyroid cartilage, also known as the Adams Apple, is a minor but essential organ. The Adams apple, protects the vocal cords which are located directly behind it.
Your Vocal Cords, have three actions, opening, closing and vibrating. When they are open, air is flowing through. When they are closed they prevent any air from passing A.K.A., holding your breath. When they are vibrating, they are producing sound like speech or singing.
The Trachea, or Wind Pipe is 10-16cm long. The Trachea, carries air between the Pharynx to the Lungs.
The Bronchi, are the tubes that feed the lungs with air. They break off into smaller tubes called Bronchioles.
The lungs are one of the most essential organs in your body. Their function is to deliver air to the bloodstream of your body.
The Diaphragm, is a muscle just below the lungs. When the diaphragm contracts it brings air in. When it relaxes air is able to flow out.
Is This System Connected To Any Other Systems?
Why yes it is. This system supplies oxygen to the bloodstream. The blood flows through the Heart, and the heart is part of the Circulatory system.
What Are Some Common Problems With This System?
One of the most common diseases that has to do with this system is Asthma. Over 20 million Americans have Asthma. Though not harmful to many people, about 1-2% of the worlds population have severe Asthma which, if not treated properly,
can kill you.
Another, more fatal disease that can occur in the Respiratory system is Lung Cancer. If not treated, the cancer can grow, filling up your Lungs.
Your Nervous System, is the system that tells your muscles and organs what to do. These messages come from the Brain.
What Does The Nervous System Do?
For example, the Nervous system tells your brain to move the muscles in your arm to move your hand away from a hot fire.
How many organs are in this system?
There are seven organs in this system. These organs, are all fine-tuned to help you avoid dangerous heat and extreme cold.
What are these seven organs you speak of?
Nervous Tissue, consists of Cells. These Cells, have structures on the outside called Dendrites. These Dendrites pick-up the pain from the exterior of the body. Then the Cell sends the information to the Brain.
The brain is home to the central control system of the body. Nothing can be done without the brain. The brain is tasked of preforming/keeping/maintaining consciousness, memory, planning, respiring, heart rate, blood pressure, and digestion.
The Spinal Cord is the main transportation route of nerve signals sent from the brain and body. The Spinal Cord's secondary job is to keep you standing up-right.
Nerves act as information paths for signals to be moved between. The same as specialized cells, there are specialized nerves. One specialized nerve is specialized in carrying one-way signals to the brain.
The Meringues consist of three layers that protect the brain.
This it the toughest, most dense tissue that surrounds the brain. This protects from the brain from damage.
Arachnoid mater is a thinner version of Dura mater.
Pia mater, is the thinnest version of the Dura mater. The Pia mater contains many blood vessels that feed the brain.
The Cerebrospinal fluid that surrounds the Brain, acts as a shock absorber. This fluid surrounds all organs in the central nervous system.
These senses all conduct their messages through the nervous system. The nerves send these messages to the brain.
Parkinson's disease, is a common and well known disease that can occur in the Nervous System. Parkinson's is a disease where certain parts of the body constantly tremors. These parts are generally the hands. When you have Parkinson's, your motor skills decrease dramatically.
How Can I Keep My Nervous System Healthy
Because the Brain is a big part of this system, it is one of the most important one to keep healthy. One way to keep your Brain sharp an healthy, is to play mind enhancing games. As long as you dont let your brain into a "sleep mode" it should stay healthy.
Also to keep your mind healthy, you can make sure that you spend time writing every day.
This System Has Organs Too?
Yes, all systems have organs. This system for instance has six.
This system has many misconceived organs. For example, not many people realize that the skin is an organ or that it the biggest organ in the body.
The Six Organs Are:
The Skin, the most well-known part of our body's but the least recognized as an organ. The skin gets rid of wastes through the sweat glands. The sweat glands' main function is to produce sweat of cool you off. Its other waste removing function is to level out the salt levels in your body.
Your Lungs have a function in two systems, the Respiratory and the Excretory. In the Excretory, the lungs remove toxic gasses. The main waste that the lungs expel is Carbon Dioxide.
Your Kidneys, filter your blood. They, for example after a beer or two your blood alcohol levels are high and your kidneys filter that alcohol out of your blood so it can return to a normal level. Your kidney sends the toxins to the bladder.
These 30cm tubes that extend from your kidneys to your bladder transport the toxic wastes that the Kidney, has removed from your bloodstream.
Your Bladder, is the storage tank for your urine that needs to be "excreted" from your body. The bladder can hold about 300-600ml of liquid at a time.
wikipedia.org and cairntechnology.com
The Urethra, is a tube that connects the bladder to the outside of the body.
Argh, I've got a Problem With My Excretory System, What Could It Be?
You could have one of over ten problems with your excretory system. Here is a very common disease.
A Kidney Stone is a, as it sounds a stone that forms in your kidney. This stone, is normally made-up of calcium. This can make you feel sick, can cause vomiting, causes back pain.
The Excretory system, as most people come to the conclusion of does not include the removal of solid waste from your body. Instead, this system filters the toxins from my body.
Wow, I Just Read That Having a Kidney Stone Can be painful. How Can I Prevent it?
One very simple way, is to drink lots of water, it can help way more than you think. Another way, is to eat a balanced diet.
Don't you just want a sip?
The average person passes urine about 3,000 times a year
Kidney Stones can be the size of a golf ball!
Kidney Stones generally occur when you are 30 years old
You make 2 pints of saliva every day
An average person will consume 50 tons of food in a lifetime
Your Intestines stretch over 22 feet long!
If you were to stretch out every vein, end to end, it would stretch 100,000 km
Small animals hearts beat more times than a large animal
The heart can beat even after it is removed from the body.
Facts That Are Fun
Your left Lung is bigger than the right one because of the heart
The surface area of your Lungs are the same size of that of a tennis court
An average person breathes between 12 and 15 times a minute
The left side of your Brain controls the right side of your body and the right side of your Brain controls the left side of your body
When we get older, our Brain looses 1 gram a year
There are 1 Billion neurons in the Brain
