A thin layer of pleural fluid in this cavity causes the visceral pleura to stick to the parietal pleura so the lungs stick to the chest wall. This causes them to expand and contract with the chest during breathing, drawing air in on inspiration and forcing it out on expiration. 04% carbon dioxide. 4% carbon dioxide. Alveoli The bronchioles divide many more times in the lungs to end in tiny air sacs called alveoli. Each lung is composed mostly of about 150 million alveoli. Alveoli resembling tiny, collapsed balloons are arranged in grapelike clusters surrounded by tiny capillaries.

In the capillary beds of the lungs, carbon dioxide diffuses down its concentration gradient into the air inside the alveoli and is exhaled from the body during the next breath.

Blood pressure is also subject to many controls. The higher the pressure gradient the faster blood will flow. The difference between the heart contractions (systole) and the relaxation phase (diastole) produces a pressure gradient. In humans, systolic pressure is normally around 120 mmHg and diastolic pressure is around 80 mmHg. The difference between these two measurements is the pulse pressure and it is this pressure that represents the pressure gradient. Pulse pressure is influenced by a combination of the contractility of the heart, the circulating volume and the peripheral resistance.
