Friedman- Cardiovascular - Sheet1

Question 1

Function

Answer 1

Transportation of: oxygen & carbon dioxide, nutrients, hormones, ions.

Question 2

location of heart

Answer 2

thoracic cavity

Question 3

Apex

Answer 3

creates the cardiac notch in the lungs; rests on the diaphragm (bottom)

Question 4

base

Answer 4

broad superior port of the heart where the blood vessels leave/enter heart (top)

Question 5

cardiac notch in lungs

Answer 5

only on left side; where apex rests

Question 6

layers of heart

Answer 6

epicardium/pericardium, myocardium, endocardium

Question 7

epicardium/pericardium

Answer 7

holds heart in place; double wall sac that surrounds the heart

Question 8

myocardium

Answer 8

pumps the blood; cardiac muscle layer

Question 9

endocardium

Answer 9

glossy tissue; inner layer that lines the heart chambers

Question 10

Artery

Answer 10

blood LEAVES heart; aorta/pulmonary trunk branch to arteries

Question 11

Vein

Answer 11

blood ENTERS heart; superior/inferior vanae cavea & right/left pulmonary veins

Question 12

Atrium (atria) chambers

Answer 12

ENTRANCE from veins; superior portion of heart; not important for pumping blood

Question 13

Ventricle chambers

Answer 13

EXIT out blood into circulation; inferior portion of heart; pumps heart (pulmonary & systemic)

Question 14

side of heart with oxygen rich blood

Answer 14

left side

Question 15

systemic circulation

Answer 15

(left) cycle of pumping oygen rich blood to the appropriate tissues of the body

Question 16

Pulmonary circulation

Answer 16

(right) pumps blood to the lungs

Question 17

left ventricle

Answer 17

high levels of myochondrium (very thick) > it can push blood through systemic circulation

Question 18

Right Atrium

Answer 18

Received blood from superior and inferior venae cavae

Question 19

Right Ventricles

Answer 19

Pumps blood into pulmonary trunk-branches to form pulmonary arteries for each lung

Question 20

Left Atrium

Answer 20

Receives blood from pulmonary vein (rich in oxygen)

Question 21

AV (atrioventricular valve)

Answer 21

between atria and ventricles-prevents backflow to atria when ventricles contract

Question 22

Semilunar valves

Answer 22

guards the base of the two arteries

Question 23

Cardiac cells

Answer 23

do not require nerve impulse to contract

Question 24

contaction of heart uses

Answer 24

intrinsic conduction system/nodal system-sympathetic & parasympathertic nervous system

Question 25

intrinsic conduction

Answer 25

system built into the heart-causes depolarization of the heart muscle
