Cardiovascular System

Question 0

Cardiovascular systems functions

Answer 0

Delivery of oxygen and nutrients to the body’s tissue while removing waste and aiding in temperature regulation and acid-base balance

Question 1

Components of the cardiovascular system

Answer 1

Heart, blood vessels, and blood

Question 2

Blood

Answer 2

The fluid component of the cardiovascular system that links the internal environment of the body to the external environment by transporting material between, and to various cells and tissues

Question 3

Plasma

Answer 3

The liquid component of blood that carries hormones, plasma proteins, food materials, ions, and gases throughout the body

Question 4

Non-plasma portion of blood

Answer 4

Formed elements including red blood cells, various types of white blood cells, and platelets

Question 5

Categories of blood vessels

Answer 5

Arteries and arterioles, veins and venules, and capillaries

Question 6

Arteries and arterioles

Answer 6

Carry oxygen-rich blood away from the heart

Question 7

Veins and venules

Answer 7

Return oxygen-depleted blood to the heart

Question 8

Capillaries

Answer 8

Provide sites for gas, nutrient, and waste exchange between blood and tissues

Question 9

Arteriosclerosis

Answer 9

Hardening and narrowing of arteries due to plaque accumulation that increases blood pressure, most commonly seen in older adults

Question 10

Circuits of the heart

Answer 10

Pulmonary circuit (right side that receives oxygen depleted blood from the body) and systemic circuit (left side that pumps pumps oxygen rich blood to the body)

Question 11

Pulmonary circuit (right side of the heart)

Answer 11

Receives partially oxygen-depleted blood containing elevated levels of carbon dioxide from the body and pushes it into the lungs, where the blood releases carbon dioxide in exchange for oxygen

Question 12

Systemic circuit (left side of the heart)

Answer 12

Receives newly-oxygenated blood from the lungs and pumps it to various cells and tissues of the body

Question 13

Atria

Answer 13

Receiving chambers of the heart

Question 14

Ventricle

Answer 14

Propulsion chambers of the heart

Question 15

Atrioventricular valve

Answer 15

Heart valve that separates the atria from the ventricle

Question 16

Tricuspid valve

Answer 16

Right atrioventricular valve

Question 17

Mitral valve (bicuspid valve)

Answer 17

Left atrioventricular valve

Question 18

Venous blood

Answer 18

Blood returning to the heart through the veins

Question 19

Pulmonary arteries

Answer 19

Arteries that transport blood from the right ventricle to the lungs, only arteries that carry partially oxygen-depleted blood

Question 20

Pulmonary veins

Answer 20

Veins that transport freshly-oxygenated blood from the lungs to the left atrium, only veins that carry oxygen-rich blood

Question 21

Interventricular septum

Answer 21

Muscular wall preventing the mixture of blood between the right and left ventricles of the heart

Question 22

Cardiac cycle

Answer 22

The period from the beginning of one heartbeat to the beginning of the next

Question 23

Systole

Answer 23

Contraction phase of the cardiac cycle, during which blood leaves the ventricles

Question 24

Diastole

Answer 24

Relaxation phase of the cardiac cycle, during which blood fills the ventricles

Question 25

Valves of the heart

Answer 25

Tricuspid valve, pulmonary valve, mitral valve, aortic valve
