Pulmonary trunk is sub divided into:
Correct answer: C. Left and right pulmonary arteries
- A. Left and right pulmonary veins
- B. Left and right pulmonary trunks
- C. Left and right pulmonary arteries
- D. Superior and inferior venae cavae
Explanation
The pulmonary trunk is subdivided into two branches known as the left and right pulmonary arteries. The pulmonary trunk is a large blood vessel that originates from the right ventricle of the heart. It carries deoxygenated blood away from the heart and towards the lungs for oxygenation. After leaving the right ventricle, the pulmonary trunk quickly divides into the left and right pulmonary arteries.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
