Q2M2_Quiz 3

right ventricle

pumps deoxygenated blood into the pulmonary artery, which leads to the lungs for oxygenation.

capillary

which enable the actual exchange of water and chemicals between the blood and the tissues

veins

carry blood from the capillaries back toward the heart.

aorta

The largest artery in the body, responsible for distributing oxygen-rich blood

platelets

Cell fragments that aid in blood clotting

red blood cells

The main component of blood that transports oxygen using hemoglobin

Pulmonary veins

carry oxygenated blood from the lungs back to the left atrium of the heart.

True

Systemic circulation begins in the left ventricle and ends in the right atrium.

artery

carry the blood away from the heart

heart

Organ that pumps blood throughout the body

True

Pulmonary circulation occurs between the heart and the lungs.

Pulmonary circulation

carries deoxygenated blood to the lungs and returns oxygen-rich blood to the heart.

The heart beats faster to match the increase in breathing rate.

The circulatory and respiratory systems work together to provide cells with oxygen and nutrients and remove wastes such as carbon dioxide. When the body needs more oxygen, how does the circulatory system respond?

Blood moves more slowly through the organs to carry away more wastes.
More blood is sent to the lungs and less to the rest of the body.
The heart beats faster to match the increase in breathing rate.
The blood vessels in the arms and legs constrict to conserve oxygen.

True

Pulmonary circulation is responsible for exchanging carbon dioxide for oxygen in the lungs.

They supply the body's cells with oxygen.

How do the respiratory and circulatory systems work together?

They supply the body's cells with oxygen.
They break down food into energy and eliminate waste.
They are responsible for the movement of the body.
They send chemical signals throughout the body via hormones.

1

Arrange the steps of blood flow through the heart in the correct order.

Deoxygenated blood enters the right atrium from the body through the superior and inferior vena cava.

2

Arrange the steps of blood flow through the heart in the correct order.

Deoxygenated blood is pumped from the right ventricle to the lungs via the pulmonary artery for oxygenation.

3

Arrange the steps of blood flow through the heart in the correct order.

Oxygenated blood returns to the left atrium from the lungs via the pulmonary veins.

4

Arrange the steps of blood flow through the heart in the correct order.

Blood flows from the left atrium to the left ventricle through the mitral valve.

5

Arrange the steps of blood flow through the heart in the correct order.

Oxygenated blood is pumped from the left ventricle into the aorta to be distributed to the body.

left ventricle

pumping chamber, pumps blood to different parts of the body

left atrium

receiving chamber, receives blood that is oxygenated (oxygen concentration is high)

right atrium

receiving chamber, receives blood that is deoxygenated (oxygen concentration is low)
