Question 9

left ventricle

Answer 9

pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

Question 10

atrioventricular valves

Answer 10

valves that separate the atria and ventricles in the heart

Question 11

tricuspid valve

Answer 11

separates the right atrium and right ventricle

Question 12

mitral valve (bicuspid)

Answer 12

separates left atrium and left ventricle

Question 13

type of blood vessels

Answer 13

arteries, capillaries, veins

Question 14

arteries

Answer 14

bring oxygen rich blood from heart to rest of body

Question 15

capillaries

Answer 15

receive blood from the arterioles and return it to the venules

Question 16

aorta

Answer 16

largest artery in the body!

-the artery that carries blood pumped from the LEFT ventricle of the heart into systemic circulation

Question 17

veins

Answer 17

vessels that return blood to the heart
- have thinner walls

Answer 18

-largest vein in the body!

-brings deoxygenated blood back to the heart

Question 19

pulmonary veins

Answer 19

-bring blood from the lungs to the heart

-are among the few veins that carry oxygenated blood!

Question 20

Which layer of the heart contains striated muscle fibers for contraction of the heart?

Answer 20

myocardium: the layer of the heart that contains the muscle fibers responsible for contraction

Question 21

endocardium/epicardium/pericardium

Answer 21

• inner layer of heart wall
• outer layers of heart wall
• pericardium - sac in which the heart sits inside the chest cavity

embolus

Answer 24

piece of plaque or clotted blood traveling thru vessels

Question 25

hemoglobin

Answer 25

-functional unit of a erythrocyte

-iron containing protein that facilitates gas exchange by binding to oxygen or carbon dioxide

Question 26

anemia

Answer 26

condition that occurs when hemoglobin levels are low, either b/c the body isn’t producing enough red blood cells,
