Transcript of Circulatory System Project

System What is this organ systems
purpose? What are the major components
of this organ system? The Heart
Your Veins
Your Arteries Description of the Main Oragans
of the Circulatory Sytem Heart- the heart pumps the blood through veins and arteries.
Veins- returns oxygen lacking blood to the heart.
Arteries- delivers oxygen filled blood through the body and to your muscles. How is the Circulatory System Related to the other Systems in our Body? The Circulatory System is related to the Respiratory System
because the lungs filter the oxygen into the blood stream. The Excretory System is also related to the Circulatory System because the carbon dioxide goes to your muscles and trades places with the oxygen in your blood stream. Then, the
carbon dioxide goes back to the lungs and you breathe it out. It is also related to the Muscular System because the heart pumps oxygen filled blood to the muscles in your body, and gives them nutrients and energy. Some Medical Problems in
the Circulatory System Aneurysm- an abnormal bulge in a wall of a blood vessel, mainly occurs in the aorta.
Renal (kidney) Artery Disease- caused by atherosclerosis, is an abnormal development of tissue, occuring in younger age groups.
Raynaud's Phenmenon- are spasms of smaller arteries in the fingers and toes, causes temperary lack of blood to the area.
Lymphedema- the build-up of fluid in vessels causes swelling, most often in arms and legs.
Peripheral Artery Disease- the build-up of plaque on the inside of vessel walls, the build-up narrows the artery passage. How The Circulatory
System Works The heart pumps oxygen filled blood to
the arteries, and away from the heart. It
then gives the oxygen and nutrients to
your tissues. Next, the depleted red
blood cells are sent back to the heart for
reoxygenation. The process begins again. Fun Facts A shock causes a decrease in blood volume. The decrease of blood volume causes the pain you feel.
About 8 million red cells die every second; about the same amount are produced every second.
It takes about 20 seconds for a red blood cell to travel through the body.
You can wrap all of your veins around the Earth 2.5 times.
An adult's heart pumps 4,000 gallons of blood each day.
Your "heartbeat" is really sound of the valves opening and closing to pump the blood in and out of the heart. The main purpose of the circulatory sytem is to supply and transfer blood throughout the body.
