Skeletal System
In this presentation I will share information about the human body systems.
Circulatory System
Human Body Systems
By: Morgan Copeland
3rd Period

Your skeletal system helps your body move. It also protects your organs. The marrow inside your bones creates blood for your body.
Your skeletal system includes your bones, joints, and cartilage..
Our bones are six times stronger than a piece of steel that is same weight.
The size of a grain of rice is about the same size as our smallest bone.
Out of the 206 bones that make our body 52 of them are in our feet.
The calcium that is stored in your bones make your bones hard.
Nervous System- Your vertebrae protects your spinal cord.
Muscular System- Your skeletal system and muscular system work together to help your body be able to move.
Immune System- Your skeletal system creates white blood cells in the marrow of your bones.
The smallest bone in your body is called the stirrup.
Your thigh bone is a quarter of your height.
The pelvis is the largest bone in your body.
Muscular System
You have three different types of muscles smooth, cardiac, and skeletal. You have over 600 muscles in your body.
The musular system help us do things such as sitting, walking, and standing. The main purpose of the muscular system is to help us move.
Did You Know?
Our muscles make up more than half our weight.
You have no control over most your muscles.
Your muscle cells produce enough heat to boil two pints of water.

Circulatory- Your heart is a muscle.
Digestive- Your esophagus is a muscle that pulls the food down to your stomach.
Nervous- Your nervous system is in control of the movements that your muscles make.
There are 3 different major parts in the circulatory system
the blood, the heart, and the blood vessels (arteries, veins, and capillaries).
The circulatory system transports materials in your body such as water, oxygen, and nutrients. It carries away waste such as carbon dioxide that your body cells produce.
Respiratory- Your circulatory and respiratory system work together to put oxygen in your blood.
Skeletal- The marrow in your bones create blood for the circulatory system.
Nervous- Your nervous system controls your heartbeat.

In a human adult the average length is 60,00 miles of capillaries, veins, and arteries.
The caperillaries take up 80% of this length.
Your heart can still beat after being taken out of your body.
The average woman's heart beat is faster than a man's.
Digestive System
Digestive System

Your digestive system includes your mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anus. Your gall bladder, liver, and pancreas all help your digestive system, but they are not a part of the digestive system.
Your digestive system is the organ system responsible for digesting food and turning them into the nutrients our bodies need. These nutrients are absorbed into the body through the small intestine.
Nervous- Your brain controls your drinking and eating behavior.
Musclular- You use your muscles to lift food to your mouth. Your esophagus is a muscle that moves the food to your stomach.
Circulatory- This system carries nutrients (blood) to the digestive system.

Your small intestine does most of your digstion not your stomach.
Your mouth produces between .75 to 1.5 liters of saliva a day
Your stomach can hold around 1.5 liters of materials.
It takes two to five seconds for food to go from your esophagus to stomch.
Respiratory System
First air goes through your mouth or nose then to your pharynx. Then the air goes to your larynx and your trachea . The air then goes to bronchial tubes and finally to your lungs.
First the Air Goes To
Mouth or Nose
Then The Air Goes To
After That The Air Goes To
The Air Then Travels To
The Then Air Goes To
Finally The Air Reaches
Where Does Your Air Go?
Bronchial Tubes
The air body cells need to live and carry out their normal functions is bought in by the lungs.Waste products such as carbon dioxide leave the body with help from your lungs
Did You Know?
Your right lung is slightly larger than your left lung.
The surface area of your lung is roughly the same size as a tennis court.
Most people breathe between 12 to 15 times a minute.
A cough travels slower than a sneeze.
Excretory System
The parts included in the process in which the excretory system removes waste from the body are the lungs, skin, and urinary system (kidneys).

The excretory's main function is to remove waste from th body. Waste leaves the body when you sweat through the skin. The lungs get rid of waste by exhaling. When you exhale your body lets out carbon dioxide that the body does not need. The urinary system (kidneys) removes liquid waste from the body.
Facts About the Excretory System
The left kidney is always higher than the right kidney.
The vein that leads to the kidney is the largest vein in your body.
Your bladder is just as large your brain.
Kidney failure has caused more than 11% of deaths in Australia.
Nervous System
There are two main parts of the nervous system the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord. The peripheral nervous system includes nerve fibers which extend to different parts of the body.
The brain sends messages through the spinal cord and the nerves (peripheral) to control the movement of muscles and the functions of the organs.
Circulatory System- Removes waste from blood (kidneys).
Digestive System- Your intestines absorb nutrients and remove excess waste from the body.
Nervous- Your nervous system is in control of the movements that your muscles make.
Endocrine- Your endocrine system works with your central nervous system to control the creation of specific hormones and enzymes.

There are more nerves in the human brain than there are stars in the Milky Way.
The left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body.
You lose about a gram of brain each year.
Only 4% of your brain cells are active.

Immune System
The immune system includest t cells, b cells, white blood cells, bone marrow, and macrophage.
The main function of the immune system is to fight pathogens. The purpose of the immune system is to keep infectious microorganisms, such as certain bacteria, viruses, and fungi, out of the body, and to destroy any infectious microorganisms that do invade the body.
Circulatory-The circulatory system consists of the blood vessels and heart and is a major pathway used by immune cells to travel through the body.
Integumentary-You lose thousands of skin cells every day, and when the dead skin cells fall off so do pathogens on your skin.
Skeletal- Your bone marrow creates white blood cells.

Interesting Facts
Fever can sometimes help the immune system fight off certain pathogens because they cannot tolerate higher temperatures.
Stress can weaken your immune system.
Too much vitamins can suppress the immune system.
Dieting weakens the immunes system.
Getting under 5 hours of sleep can depress your immune system.

Circulatory- Your circulatory and respiratory system work together to put oxygen in your blood.
Skeletal- Your ribs protect your lungs.
