Double Circulation

Deoxygenated blood enters the heart through

• right atrium

• left atrium

• right ventricle

• left ventricle

Oxygenated blood leaving the heart through

• Right atrium

• Left atrium

• Right ventricle

• Left ventricle

Which blood vessel carries the blood the deoxygenated blood to the lungs

• pulmonary veins

• pulmonary arteries

• aorta

• vena cavae

The blood that enters the heart in pulmonary circulatory is rich of

• carbon dioxide

• carbohydrate

• oxygen

• carbon monoxide

In systemic circulatory, the blood is distributed to all part of body except

• lungs

• brain

• gut

• liver

In systemic circulatory, the blood binds _____ before returns to the heart

• lipid

• oxygen

• carbondioxide

• protein

Which blood vessels carry the blood from all parts of the body back to the right side of the heart

• veins

• aorta

• arteries

• capillaries

The blood entering the lungs flow more slowly once it is in the lungs, this allows the blood to

• have sufficient time to be oxygenated

• stop flowing

• flow back to the heart

• flow to the body

The blood flows throughout the body faster than the blood that enters the lungs. This will make the oxygenated blood

• keep the oxygen

• return back to the heart oxygenated

• distribute oxygen more quickly

• oxygenated well before returns to the heart

The blood flows throughout the body faster will make it easier to maintain the

• metabolic rate in mammals

• breathing rate in mammals

• cancer rate in mammals

• sweating rate in mammals
