The Circulatory System

What is the purpose of the circulatory system?

What is the purpose of the circulatory system? To move materials through out the body: Oxygen Carbon dioxide & other wastes Nutrients Hormones Antibodies

What are the 3 types of circulation?

What are the 3 types of circulation? System – between heart to body systems Pulmonary – between heart & lungs Coronary – between heart & heartS

What is coronary circulation?

What is coronary circulation? The flow of blood to and from the tissues of the heart When the coronary circulation is blocked, oxygen and nutrients cannot reach all the cells of the heart. This can cause a heart attack

What is coronary circulation? The heart receives the oxygen and nutrients that it needs from the blood The blood also carries away wastes from the heart's cells

What is pulmonary circulation?

What is pulmonary circulation? The flow of blood through the heart to the lungs and back to the heart

Trace the pathway of blood from heart to lungs and back.

Trace the pathway of blood from heart to lungs and back. Blood, high in carbon dioxide and low in oxygen, returns from the body to the heart. It enters the right atrium through the superior and inferior vena cavae.

Trace the pathway of blood from heart to lungs and back. B. The right atrium contracts, forcing the blood into the right ventricle. When the right ventricle contracts, the blood leaves the heart and goes through the pulmonary artery to the lungs. The pulmonary arteries are the only arteries that carry blood that is high in carbon dioxide

Trace the pathway of blood from heart to lungs and back. C. Oxygen-rich blood travels from the lungs through the pulmonary vein and into the left atrium. The pulmonary veins are the only veins that carry oxygen-rich blood.

Trace the pathway of blood from heart to lungs and back. D. The left atrium contracts and forces the blood into the left ventricle. The left ventricle contracts, forcing the blood out of the heart and into the aorta.

What are the functions of the systemic circulation system in your body?

What are the functions of the systemic circulation system in your body? It moves oxygenated (oxygen-rich) blood to organs and body tissues. It returns un-oxygenated (oxygen-poor) blood to the heart.

List the parts of the circulatory (or cardiovascular) system:

List the parts of the circulatory (or cardiovascular) system: Heart Blood vessels Arteries Veins Capillaries Blood

Compare & contrast the three types of blood vessels.

Compare & contrast the three types of blood vessels. All 3 blood vessels transport (move) blood. Capillaries are only one cell thick. Arteries & vein have 3 layers. Veins have valves.

Compare & contrast the three types of blood vessels. Arteries carry blood away from the heart. Veins carry blood to the heart. Capillaries connect arteries & veins. Diffusion takes place in capillaries.

Describe arteries

Describe arteries Blood vessels that carry blood away from the heart Have thick, elastic walls made of connective tissue and smooth muscle tissue

Describe veins

Describe veins Blood vessels that carry blood back to the heart Have one-way valves that keep blood moving toward the heart

What is blood pressure?

The force of the blood on the walls of the blood vessels. What is blood pressure? The force of the blood on the walls of the blood vessels.

What is the purpose of blood vessels?

What is the purpose of blood vessels? Blood vessels carry the blood to every part of your body

What does blood do?

What does blood do? Blood moves oxygen and nutrients to cells Carries carbon dioxide and other wastes away from the cells Sometimes the blood carries substances made in one part of the body to another part of the body where they are needed

What is the heart?

What is the heart? An organ made of cardiac muscle tissue

Describe the heart

Describe the heart Located behind your breastbone, called the sternum, and between your lungs Has four compartments called chambers The two upper chambers are called the right and left atria The two lower chambers are called the right and left ventricles

Describe the heart During one heartbeat, both atriums contract at the same time Then, both ventricles contract at the same time A one-way valve separates each atrium from the ventricle below it

Describe the heart The blood flows only in one direction from an atrium to a ventricle, then from a ventricle into a blood vessel A wall prevents blood from flowing between the two atriums or the two ventricles This wall keeps blood rich in oxygen separate from blood low in oxygen If oxygen-rich blood and oxygen-poor blood were to mix, your body's cells would not get all the oxygen they need
