Question

Blood flow in lungs is circulated by:

• A. Cardiac circulation
• B. Pulmonary circulation
• C. Gastric circulation
• D. Trachea

Hint:

Types of circulation:
Pulmonary circulation → Heart ↔ Lungs
Systemic circulation → Heart ↔ Body tissues Always link the organ with its specific circulation type.

Answer 1

The Correct Option is B

Step 1: Understand what pulmonary circulation is. Pulmonary circulation refers to the movement of blood between the heart and the lungs.
Step 2: Describe the pathway.
Deoxygenated blood is pumped from the right ventricle to the lungs via the pulmonary artery.
In the lungs, blood becomes oxygenated.
Oxygenated blood returns to the left atrium via the pulmonary veins.
Step 3: Eliminate incorrect options.
Cardiac circulation: Not a standard term for lung circulation.
Gastric circulation: Refers to blood flow to the stomach.
Trachea: An air passage, not a circulatory system.
Hence, the correct answer is \[ \boxed{\text{Pulmonary circulation}} \]
