Blood Flow

Question 1

Blood flows through the heart in the following order:

Answer 1

1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.

Question 2

-Blood fills the chamber
-AV valve hangs limply

Answer 2

Relaxation

Question 3

-AV valves are closed
-Blood is released

Answer 3

Contraction

Question 4

-Has three flaps

Answer 4

Tricuspid Valve

Question 5

-Has two flaps
-Also called left AV valve or mitral

Answer 5

Bicuspid Valve

Question 6

Carries blood to the lungs in terms of pulmonary trunk

Answer 6

Pulmonary arteries

Question 7

Divides into the left pulmonary artery and right pulmonary trunks

Answer 7

Pulmonary Trunk

Question 8

Delivers blood to the cell

Answer 8

Capillaries

Question 9

Where gas exchange happens

Answer 9

Alveoli

Question 10

• Blood goes back to the heart from the lungs
• 4 veins in total
• smaller compared to the arteries

Answer 10

Pulmonary Veins

Question 11

Right ventricle to Left atrium (Heart - Lung -Heart)

Answer 11

Pulmonary Circulation

Question 12

Left Ventricle to Right Atrium (Heart - body -heart)

Answer 12

Systematic Circulation

Question 13

Prevents back flow

Answer 13

Heart Valves

Question 14

-Located between the atria and ventricle
-Closes during contraction
-Opens during relaxation

Answer 14

Atrioventricular Valve

Question 15

-Tendinous chords that anchor the flaps of the closed AV valves to prevent inversion and backflow of the blood
-Heart strings
-Tightens and anchors cusps to flow

Answer 15

Chordae Tendineae

Question 16

• Guards the bases of the two large arteries leaving ventricular chambers

Answer 16

Semilunar Valves
