Heart and Circulation

Question 1

Coronary Circulation Function

Answer 1

Supplies oxygen to myocardium

Removes carbon dioxide from myocardium

Question 2

Systemic Circulation Function

Answer 2

Provides blood to ALL body tissues
Removes CO2 and waste
Arises from aorta to Right Atrium

Question 3

Pulmonary Circulation Function

Answer 3

Transporta deoxygenated blood from right ventricle to lungs and returns oxygenated blood to left atrium

Question 4

How does a venous pump work?

Answer 4

Muscle oressed aganist walls of veins to provide force needed to move blood.

Question 5

Blood Flow beginning at arteries

Answer 5

Arteries>Arterioles>Capillaries>Venules>Veins

Question 6

Pulmonary Circuit Pathway

Answer 6

Right atrium>tricupsid valve>right ventricle>pulmonary semilunar valve>pulmonary trunk>pulmonary arteries>lungs>pulmonary veins>left atrium

Question 7

Systemic Circuit Pathway

Answer 7

left atrium>bicuspid valve>left ventricle>aortic semilunar valve>aorta>all body cells>superior/inferior vena cavae>right atrium

Question 8

Coronary Circuit Pathway

Answer 8

Aorta>coronary arteries>cardiac muscle>cardiac veins>coronary sinus>right atrium

Question 9

Blood Flow Pathway

Answer 9

Superior/Inferior vena cave>right atrium>tricupsid valve>right ventricle >Pulmonary semilunar valve>pulmonary trunk>pulmonary artery>lungs>pulmonary veins>left atrium>bicupsid valve>left ventricle>aortic semilunar valve>ascending aorta>blood returns

Question 10

Coronary Arteries

Answer 10

Recieve aortic blood and sends blood to cardiac muscle

Question 11

Cardiac Veins

Answer 11

Recieves cardiac muscle blood and sends blood to coronary sinus

Question 12

Papillary Muscle

Answer 12

Attach into ventricular walls

Question 13

Coronary Sinus

Answer 13

Recieves cardiac vein blood and sends blood to right atrium

Question 14

Chordae Tendineae

Answer 14

Attach atrioventricular valve cusps to papillary muscles

Question 15

Valve Functions

Answer 15

Prevents backflow of blood
