Question 9

Heart

Answer 9

Large muscle divided into four chambers. Top chambers= right atrium and left atrium. Bottom chambers= right and left ventricles.

Question 10

Why does the left ventricle have a thicker muscular wall

Answer 10

Left side of the heart has to pump blood around the body whereas the right side has to pump blood to lungs.

Question 11

Heart valves

Answer 11

Four heart valves. Function is to ensure that blood only flows in one direction through the heart.

Enters the right atrium of the heart in a vein known as the vena cava. Blood is deoxygenated

Question 14

Where is the blood pumped into from the right atrium

Answer 14

Into the right ventricle, through a valve, and then away from the heart in a pulmonary artery.

Question 15

Where does oxygenated blood return to

Answer 15

Left atrium of the heart in the pulmonary vein.

Question 16

Blood flows from the left atrium….

Answer 16

Through a valve to the left ventricle and then leaves the heart in the aorta.

Question 17

What is the hearts blood supply provided by

Answer 17

Coronary artery

Question 18

WhT are the three main types of blood vessels.

Answer 18

Arteries. - carry blood away from the heart.
Capillaries.- involved in exchange of materials.
Veins.- carry blood to the heart.

Question 19

Arteries carry what type of blood around the body

Answer 19

Oxygenated blood

Question 20

Capillaries

Answer 20

Referred to as exchange blood vessels. Their walls are only one cell thick.

Question 21

What blood do veins carry

Answer 21

Deoxygenated blood with the exception of the pulmonary vein.
