Cardiovascular System

Question 1

What does the right atrium do

Answer 1

Receives blood and pumps it to the right ventricle

Question 2

Right ventricle

Answer 2

Pumps blood to the lungs where there’s oxygen

Question 3

Left atrium

Answer 3

Receives pumped oxygenated blood from lungs and pumps it to the left ventricle

Question 4

Left ventricle; strongest side

Answer 4

Pumps the oxygenated to the rest of the body and causes a blood pressure

Question 5

Superior vena cava

Answer 5

Brings deoxygenated blood from head

Question 6

Inferior vena cava

Answer 6

Brings deoxygenated from the body

Question 7

Aorta

Answer 7

Arching blood vessels with branches attached to head and body to support oxygenated blood

Question 8

Left and right pulmonary veins

Answer 8

Carry deoxygenated blood from the heart to the left and right lungs

Question 9

What is autorhythmnicity

Answer 9

Ability of insisting a cardiac action potential at fixed rate by cardiac muscles

Question 10

Epicardium

Answer 10

Thin outer layer that protects outside of heart

Question 11

Myocardium

Answer 11

Middle layer of the heart that contains the cardiac

Question 12

Smooth endocardium

Answer 12

Responsible for keeping blood from sticking to the inside of heart and forming blood clots in heart

Question 13

What is septum

Answer 13

Separates heart into left and right sides

Question 14

Apex

Answer 14

Formed by the left ventricle

Where the inferior and aterior parts are found

Question 15

Mitral valve and tricuspid

Answer 15

Control blood blow from atria to the ventricles

Question 16

Aortic valve and pulmonary valve

Answer 16

Control blood flow out of the ventricles

Question 17

Systemic circulation

Answer 17

Carries oxygenated blood from left ventricles through the arteries, to the capillaries in the tissues of the body

Deoxygenated blood returns from tissue capillaries through a system of veins to the right atrium of the heart

Question 18

Blood pressure

Answer 18

Amount of force the heart has to use to pump blood around the body

Question 19

Cardiac output

Answer 19

Volume of blood ejected per min from the left ventricle to the aorta

Question 20

Peripheral resistance

Answer 20

Resistance of arteries to blood flow: increases when arteries constrict and when decreases when they dilate

Question 21

Stroke volume

Answer 21

Amount of blood ejected by left ventricle during each heartbeat

Question 22

Heart rate

Answer 22

Number of heartbeat per min

Question 23

Acute Haemolytic Reaction

Answer 23

Triggered by host antibodies destroy donor red blood cells

Question 24

Blood group A

Answer 24

A antigens on red blood cells + B anti bodies in the plasma

Question 25

Blood group B

Answer 25

Had B antigens + A antibodies in the plasma

Question 26

Blood group O

Answer 26

Has no antigen and both anti A and anti B bodies in the plasma

Question 27

Blood group AB

Answer 27

Both A + B antigens and no antibodies

Question 28

Aorta

Answer 28

Contains blood at the highest pressure
