Question 9

Blood Pressure

Answer 9

Pressure of the blood against the wall of the blood vessels, especially the arteries

Question 10

Vasodilation

Answer 10

When the veins swell up or dilate; widening the internal diameter (lumen) of the blood vessel to allow increased blood flow

Question 26

What is the aorta

Answer 26

The main artery that carries blood away from the heart to the rest of the body

Question 27

Function of the left atrium

Answer 27

Receives blood straight from the lungs (oxygenated) which empties into the left ventricle

Question 28

Function of left ventricle

Answer 28

Pumps oxygenated blood through aortic valve to the rest of the body

Question 29

Function of the right ventricle

Answer 29

Passes blood to the pulmonary artery which sends the blood to the lungs to pick up oxygen

Question 30

Function of the right atrium

Answer 30

Receives deoxygenated blood from the rest of the body then empties into the right ventricle.

Question 31

Pulmonary valve

Answer 31

Acts as a one way door between the pulmonary artery and the right ventricle

Question 32

Pulmonary artery

Answer 32

Carries blood from the right side of the heart to the lungs to get oxygenated

Question 33

Bicuspid valve

Allows blood to flow from the left ventricle to the aorta with any back flow of blood

Question 34

Function of the tricuspid valve

Answer 34

Opens to Allows blood to flow from right atrium to ventricle and when the ventricle contract they close to prevent any back flow of blood
