Pulmonary Circuit

Q. (a) Name the only artery that carries carbon dioxide-rich blood.
(b) Why is it called an artery if it does not carry oxygen-rich blood?

Q.

Which of the following is correct about the pulmonary artery?

I : It contains oxygen rich blood

II : It contains carbon dioxide rich blood

III : It carries blood pumped from the heart to lungs

IV : It carries blood from the lungs to the heart

1. I and III

2. II

3. I and IV

4. II and III

Q. Which of the following structures are directly involved in the "pulmonary circuit"?

1. Superior vena cava, right atrium, left ventricle
2. Right ventricle, pulmonary arteries, left atrium
3. Left ventricle, aorta, inferior vena cava
4. Right atrium, aorta, left ventricle

Q. Where in the human body is the deoxygenated blood get oxygenated?

1. Heart
2. Lungs
3. Kidneys
4. Liver

Q.

The blood circulation that passes through the lungs is called __ circulation.

Q.

Pulmonary arteries carry oxygenated blood. True or false?

1. True

2. False

Q.

There are two circuits the blood circulates in.

Choose the options that correctly shows the direction of blood in the heart, lungs and body and the type of the circulation. (You may choose more than one option.)

1. Systemic Circulation: Right Ventricle ⟶ Lungs ⟶ Left Atrium

2. Pulmonary Circulation: Right Ventricle ⟶ Lungs ⟶ Left Atrium

3. Systemic Circulation: Left Ventricle ⟶ Body ⟶ Right Atrium

4. Pulmonary Circulation: Right Ventricle ⟶ Body ⟶ Left Atrium

Q. Which of the following are parts of the pulmonary circuit?

1. Blood from heart is carried to the lungs for oxygenation
2. Blood from all parts of the body is brought back to the heart
3. Oxygenated blood is pumped from the heart to all parts of the body
4. Oygenated blood is transported from the lungs to the heart.

Q. Sort this according to the order in which oxygenated blood from the lungs travels to other parts of the body.

1. Aorta
2. Left atrium
3. Pulmonary vein
4. Left ventricle
5. Lungs

Q. Sort the parts according to the order in which deoxygenated blood travels from the heart to the lungs.

1. Lungs
2. Right Ventricle
3. Pulmonary artery
4. Right Atrium
