During inspiration, the volume of the lungs is actively increased by the action of the diaphragm. As the volume of the lungs increases, the pressure within the lungs falls about 1 mmHg below atmospheric pressure. Air rushes into the lungs due to this pressure difference.

The human circulation system has approximately 1X109 capillary vessels. Each vessel hasa diameter of about 8μm. Assuming cardiac output is 5L/min, determine the averagevelocity of blood flow through each capillary vessel.
In order to draw air into your lungs, your diaphragm and other muscles contract, increasing the lung volume. This lowers the air pressure of the lungs to below atmospheric pressure, and air flows in. When your diaphragm and other muscles relax, the volume of the lungs decreases, and air is forced out. (a) If the total volume of your lungs at rest is 5.31 L and the initial pressure is 749 mmHg, what is the new pressure if the lung volume is increased to 5.45 L? mmHg(b) If the total volume of your lungs at rest is 5.31 L and the initial pressure is 749 mmHg, at what volume will the pressure be 769 mmHg? L
