What is the purpose of the pulmonary circulation cycle?

The pulmonary circulation cycle is essential for the respiratory process, focusing specifically on the exchange of gases. Its primary purpose is to remove carbon dioxide from the blood and pick up oxygen from the lungs.

During this cycle, deoxygenated blood is pumped from the right side of the heart to the lungs through the pulmonary arteries. In the lungs, carbon dioxide is expelled from the blood and oxygen is absorbed. This oxygen-rich blood is then returned to the left side of the heart through the pulmonary veins, where it can be pumped into systemic circulation to supply oxygen to the rest of the body.

This process is vital for maintaining the oxygen and carbon dioxide balance in the body, which is crucial for cellular respiration and overall metabolic processes.
