The Cardiovascular System

Question 1

What system is the most important biological system?

Answer 1

cardiovascular system

Question 2

How does the cardiovascular system transfer oxygen to the mitochondria in every cell?

Answer 2

by way of the red blood cells

Question 3

What does the cardiovascular system transfer?

Answer 3

nutrients requires by the cells to form ATP and other important chemical structures

Question 4

How does the blood flow in the cardiovascular system?

Answer 4

blood flows from the high pressure chamber (left ventricle) to the low pressure chamber

Question 5

How is the cardiovascular system designed?

Answer 5

in parallel

Question 6

What happens if there is a decrease of blood in a certain area?

Answer 6

there is an instant redirection of blood to major organs

Question 7

What is the cardiovascular system characterized by?

Answer 7

systemic arteries

Question 8

What do systemic arteries carry

Answer 8

oxygenated blood

Question 9

What does the systemic venous system carry?

Answer 9

deoxygenated blood

Question 10

What happens in case something interferes with the transport of oxygen into the lungs?

Answer 10

the hemoglobin in the red blood cells attaches 4 oxygen molecules

Question 11

Av valves

Answer 11

separate the atrial from the ventricles

Question 12

Semilunar valves

Answer 12

control the output from ventricles

Question 13

Electrocardiogram (ECG)

Answer 13

records the electric signals generated and transmitted by the contracting cardiac muscle of the atria and ventricles

Question 14

Coronary arteries

Answer 14

first branches of the aorta

Question 15

What are coronary arteries essential for

Answer 15

supplying oxygen to the cardiac muscle during diastole so that blood flows through the capillaries of the heart muscle
