Forces in Function | The Common Vein

Principles

Physiology relates to the interaction of the forces in the body. The forces have both physical and chemical forms.

Keeping the Lungs attached to the Chest Wall via A Two Layered Pleura ? Capillary Forces

Mechanical Forces Bringing Air to Alveoli

Gradients Created at the Alveolar Level

Oxygen Gradients Created by the Lungs Across the Alveolar Membrane
This diagram again shows the alveolus in teal, the arteriolar component of the capillary with red cells in blue and venular component replenished by oxygen in red. As noted above, the PO2 of the arterial blood is 40mmHg while the inspired air is 104mmHg. A pressure gradient thus exists and diffusion from the high to the low pressure occurs with a net movement of oxygen into the blood to equilibrate the pressure. Venous blood is now rich in oxygen with a PO2 of 104mmHg.
