Circulatory system

Question 1

Biomechanics

Answer 1

Mechanical laws that relate with the movement or structure of
living organisms

Question 2

Cardiovascular biomechanics

Answer 2

Mechanical laws that relate with the movement or structure of the cardiovascular system.

Question 3

Applications of cardiovascular biomechanics

Answer 3

Pacemaker, Heart Valve, Aortic endograft, Angioplasty and Stenting

Question 4

Pulmonary Circulation

Answer 4

Circulation of deoxygenated blood from the hearth to the lungs and back.

Question 5

Systemic Circulation

Answer 5

Circulation of oxygenated blood from the hearth to the rest of the body.

Question 6

Functions of cardiovascular system

Answer 6

transportation of red blood cells, defense and healing (white cells and platelets), thermoregulation, maintenance of fluid balances between organs an tissues.

Question 7

Vasodilatation

Answer 7

Blood vessels widen and increases blood flow. Cold

Question 8

Vasocontraction

Answer 8

Blood vessels narrow and decreases blood flow. Keeps you warm.

Question 9

Relaxation Phase / Diastole

Answer 9

Heart expands due to being filled with blood form the venous and pulmonary system.

Question 10

Contraction Phase / Systole

Answer 10

Heart contracts due to blood being released from the left and right ventricles.

Question 11

Hearth Valves

Answer 11

Ensures proper flow following pressure difference. There are four valves tricuspid, mitral, pulmonary and aortic valves.

Question 12

Artery

Answer 12

Transports blood from heart to body. Smaller arteries are called arterioles.

Question 13

Vein

Answer 13

Transports blood from body to heart. Small veins are called venules.

Question 14

Capillary

Answer 14

Exchange gas (o2 an co2) from body between arteries and veins.

Question 15

Tunica Externa (Adventitia)

Answer 15

Outermost layer, consisting of collagen fibers.

Question 16

Tunica Media (Media)

Answer 16

Layer consisting of smooth muscle, elastin sheets, and collagen fibers.

Question 17

Tunica Interna (Intima)

Answer 17

The innermost layer consisting of a single layer of endothelial cells.

Question 18

Heart wall

Answer 18

Epicardium(outer), myocardium(middle), and endocardium(inner)

Question 19

Chambers of heart wall

Answer 19

Two upper (atrium), two lower (ventricles).

Question 20

Relationship between Respiratory and Circulatory

Answer 20

Work together to sustain the body with oxygen

Question 21

Coronary Heart Disease

Answer 21

Lack of blood flow to the heart due to a presence of a plaque build up in the coronary artery.

Question 22

Aortic Aneurism

Answer 22

Bulge in the aorta caused by the weakening of its walls which rupture and causes internal bleeding.

Question 23

Ischemic Stroke

Answer 23

Caused by clotting in the carotid artery and supplying the brain with oxygenated blood.

Question 24

Hemorrhagic stroke

Answer 24

Burst of one of the arteries in the brain causing the flow of blood into its tissue.
