The pressure of the blood that enters the lung circulation is about one-sixth that of the blood entering the body circulation. suggest why?

The lower pressure of blood entering the lung circulation is necessary to prevent damage to the delicate alveolar structures and to facilitate efficient gas exchange. High pressure in the lungs could lead to fluid leakage into the alveoli, impairing oxygen absorption. Additionally, the pulmonary circulation is shorter and has less resistance compared to the systemic circulation, allowing for effective blood flow at lower pressures. This design helps maintain optimal conditions for respiratory function.
