7 What is coronary circulation? The flow of blood to and from the tissues of the heartWhen the coronary circulation is blocked, oxygen and nutrients cannot reach all the cells of the heart. This can cause a heart attack
8 What is coronary circulation? The heart receives the oxygen and nutrients that it needs from the bloodThe blood also carries away wastes from the heart's cells
11 What is pulmonary circulation? The flow of blood through the heart to the lungs and back to the heart
12 Trace the pathway of blood from heart to lungs and back.
13 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.
14 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
15 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.
16 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.
17 What are the functions of the systemic circulation system in your body?
18 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.
19 List the parts of the circulatory (or cardiovascular) system:
20 List the parts of the circulatory (or cardiovascular) system: HeartBlood vesselsArteriesVeinsCapillariesBlood
21 Compare & contrast the three types of blood vessels.
22 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.
23 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.
33 What does blood do? Blood moves oxygen and nutrients to cells Carries carbon dioxide and other wastes away from the cellsSometimes the blood carries substances made in one part of the body to another part of the body where they are needed
37 Describe the heartLocated behind your breastbone, called the sternum, and between your lungsHas four compartments called chambersThe two upper chambers are called the right and left atriaThe two lower chambers are called the right and left ventricles
38 Describe the heartDuring one heartbeat, both atriums contract at the same timeThen, both ventricles contract at the same timeA one-way valve separates each atrium from the ventricle below it
39 Describe the heartThe blood flows only in one direction from an atrium to a ventricle, then from a ventricle into a blood vesselA wall prevents blood from flowing between the two atriums or the two ventriclesThis wall keeps blood rich in oxygen separate from blood low in oxygenIf oxygen-rich blood and oxygen-poor blood were to mix, your body's cells would not get all the oxygen they need
