Transcript of Cardiovasculr, Respiratory And Digestive System

Cardiovascular, Respiratory and
Digestive System http://adagioridingstables.com/blank-heart-diagram-blood-flow Let's Begin Cardiovascular system moves blood throughout the body Nutrients and oxygen, carries away wastes and helps fight disease http://laughingsquid.com/realistic-bleeding-heart-valentines-day-cakes/ Pumps blood throughout
the body cells Carries oxygen through your body
Takes the nutrients and delivers it through the body
Transport waste to kidneys
Helps white blood cells fight disease 40% contain red blood cell which contain hemoglobin 55% of your body contains plasma Platelets cause clots in your body Blood Humas have 4 types of blood
A,B, AB, and O Blood is the fluid that delivers oxygen, hormones, and nutrients to the cells and carries away wastes 1. PLasma 2. Red Blood Cells 4. Platelets 1. Arteries Carry oxygenated blood away from the heart;
deliver blood to capillaries 2. Capillaries http://www.virtualmedicalcentre.com/anatomy/blood-function-and-composition/30 Carries blood throughout the body
There are 3 main types
2. Capillaries
3.Veins consists of a network of vessels and tissues that move and filter lymph, the clear fluid that fills the spaces around body cells Like White Cells the cells in the Lymphatic System fights off pathogen Lymphatic System contains fats and specialized white blood cells called lymphocytes Basically the lymphatic system provides
immunity against disease Problems with the cardiovascular and lymphatic systems first appear later in life Reduce it with Health Behaviors( few tips) Cardiovascular system Problems Congenital heart defect
Heart murmurs
Varicose veins
Leukemia Lymphatic System Problem Tonsillitis
Immune deficiency
Hodgkin's disease Cardiovascular system provides... removes carbon dioxide from the body and provides it with fresh oxygen Respiratory System Blood Vessels 3. Veins Pathogen: a microorganism that causes disease 3. White Blood Cells White cells protect body Blood is made up of the following components vessels that return blood to the heart Small vessels that carry blood from arterioles and to small vessels called venules which empty into veins; form vast networks throughout the tissues and organs Cardiovascular System Continues Respiratory System can be divided into two parts External Respiration oxygen moves from the lungs into the blood and carbon dioxide moves from the blood into the lungs Internal respiration oxygen moves from the blood into the the cells and carbon dioxide moves from the cells into the blood How it works The diaphragm and your muscles between your ribs expands your chest cavity and lungs as you inhale
Your muscles relax and your chest cavity decreases as you exhales The Lungs Air moves into the lungs through the trachea Trachea branches out into two bronchi Airways becomes smaller as you go deeper Bronchioles brings air closer to the site of external respiration Other Respiratory Structures Also includes upper airways such as the mouth and nose Membranes of the nose are lined with hairlike sructures called cilia and with cells that produce mucus Cilia and mucus work together to help prevent foreign particles Larynx(voice box) contains tow bands of tissue that produce sound when air forced between them causes them to vibrate Keep your Respiratory Health Don't smoke or use tobacco is the number one thing to keep your respiratory system healthy
Regular Physical activity
Wash your hands regularly
Eliminate your exposure to pollutants in the air this include ETS Problems that can occur Sinusitis
Emphysema 2 1 Can be divided into 3 parts Digestion Absorption Elimination Is the mechanical & chemical breakdown of foods within the stomach & intestines for use by the body's cells Is the passage of digested food from the digestive tract into the cardiovascular system Is the body's expulsion of undigested food or body wastes The Digestive System There 2 process to the digestion system 1. Mechanical Process which includes the Teeth, Salivary glands and the Tongue This process involves chewing , mashing and breaking down food Second is Chemical Process This involves secretion produced by digestive organs In the small intestine two other digestive organs mix with the food to continue the process of digestion
1. Pancreas creates enzymes that break down the carbohydrates, fats, and prteins in food.
2. Liver creates a digestive juice- bile 10 inch long that is connected to the pharynx with the stomach swallows the food Esophagus The stomach is a hollow, sac- like organ enclosed in a wall of muscles.
It has 3 tasks:
1. Mixing foods with Gastric juices
2. Storing partially digested food and liquid
3.Moving food into the small intestine The large intestine job is to absorb water, vitamins, and salts and to eliminate waste Bile is stored int gallbladder between meals http://bedahunmuh.wordpress.com/2010/05/12/topography-and-constrictions-of-esophagus/ http://web.onetel.net.uk/~dh_mosley/STEM-HumanBody/digestive_system.htm It depends on the heart and its systems of blood vessels Your Heart is the muscles the makes the cardiovascular system work eat a well-balanced diet maintain a healthy weight exercise regular for at least 30 min. Avoid Ets and using tobacco products Avoid illegal drugs keep blood pressure within range below 120/80 is normal * reminder blood pressure at 140/90 is considered high And chronic high blood pressure can cause Cardiovascular disease. Intestines Large Intestines Small Intestines Consists of three parts
1. The Duodenum
2.The Jejunum
3.The ileum 90% of all nutrients are absorb through the small intestine The millions of villi absorb the nutrients Like all the systems in your body, problems can occur in the digestive system Functional Problems Structural Problems This can be effected by illness, stress or eating a particular food.
They can conclude the following: Indigestion- a feeling of discomfort in the upper abdomen Constipation- causes the feces to become dry and hard making bowel movements hard Heartburn is a burn in the chest that may rise up to the throat Passing Gas is normal but excessive gas can result in cramps or and uncomfortable feeling of fullness in the abdomen Nausea- is the feeling of discomfort that sometimes preceeds vomiting Diarrhea is the frequent passage of watery feces Some structural problems are temporarily others are serious
Here are a few: Tooth decay can make it difficult to chew Gastritis an inflammation that lies within the stomach A peptic ulcer is a sore in the lining of the digestive tract Gallstones can block the bile duct between the gallbladder and the small intestine Lactose intolerance- inability to digest lactose(a type of sugar found in milk) Appendicitis is inflammation of the appendix Colitis is the inflammation of the colon Hemorrhoids veins in the rectum and anus that may become swollen and inflamed Crohn's disease inflammation of the lining of the digestive tract Cirrhosis is caused by heavy drinking Basically, the digestive system, provides nutrients and energy for your body through the digestion of food.
