EXAM 3: Med Terms / Cardio A&P

Question 1

A natural structure or artificial device, in a passage or vessel that prevents reflux of the fluid contents passing through it.

Answer 1

valves

(valves in veins are membranous folds that prevent backflow of blood

Question 2

The valve at the junction of the left ventricle and the ascending aorta.

It is composed of 3 segments (semilunar cusps) and prevents regurgitation

Answer 2

aortic valve (AoV)

Question 3

Any of the four valves that prevent the backlow of blood as it passes into, through, and out of the heart.

Answer 3

cardiac valve
(In order of entry into right atrium: tricuspid, pulmonary, mitral, aortic)

Question 4

The valve at the entrance of the Inferior Vena Cava

Answer 4

eustachian valve

Question 5

The valve that closes the orifice between the left cardiac atrium and the left ventricle during ventricular systole

Answer 5

mitral valve

SYN: bicuspid; left atrioventricular

Question 6

The valve at the junction of the right ventricle and pulmonary artery.

It is composed of three semiluar cusps and prevents regurgitation of blood from the pulmonary artery back into the right ventricle

Answer 6

pulmonary valve

Question 7

The valve that closes the orifice between the right cardiac atrium and right ventricle during ventricular systole

Answer 7

tricuspid valve

SYN: right atrioventricular

Question 8

The endothelial membrane that lines the chambers of the heart and is continuous with the lining of the arteries and veins.

It is a single layer of cells under which lie nerves, Purkinjie cells, and veins

Answer 8

endocardium

Question 9

The membranous fibroserous sac, enclosing the heart and the bases of the great vessels.

Consists of three layers

Answer 9

pericardium

Question 10

Three layers of the paricardium

Answer 10

1. Visceral layer (Inner) - also, EPICARDIUM
2. Parietal layer (Lines the interior of Fibrous layer)
3. Fibrous layer

Question 11

The space between the two serous layers of pericardium (epicardium - parietal) is the __ __

Answer 11

pericardial cavity

filled with serous fluid, reduces friction as the heart beats

Question 12

Vessels through which the blood passes away from the heart to various parts of the body

Answer 12

arteries

Question 13

Three parts of the artery

Answer 13

Tunica

1. adventitia
2. media
3. intima

Question 14

Any one of the many vessels that convey blood from the capillaries as part of the venous system, the systemic venous network, or the portal venous complex

Answer 14

veins

Question 15

Most of the veins of the body are systemic veins that convey blood from the whole body (except lungs) to the right atrium of the heart

Question 16

The main artery of the body, supplying oxygenated blood to the circulatory system.

In humans it passes over the heart from the left ventricle and runs down in front of the backbone.

Answer 16

aorta

Question 17

One of two large veins returning blood from the peripheral circulation to the right atrium of the heart

Answer 17

vena cava

Question 18

Any one of the network of muscular tubes that carry blood

Answer 18

capillaries

Question 19

An artery supplying blood to the heart

Answer 19

coronary arteries

Question 20

The general blood circulation of the body, not including the lungs

Answer 20

systemic circulation

also called, greater circulation
