What two parameters are responsible for creating the movement filtration and reabsorption of fluid across capillary wall a sprained ankle?

Starling forces

The Starling forces are responsible for the movement of fluid across capillary walls. These forces are:

* Hydrostatic pressure: The pressure exerted by the fluid inside the capillary.

* Osmotic pressure: The pressure exerted by the solutes (such as proteins) in the fluid inside the capillary.

The net effect of the Starling forces determines whether fluid moves into or out of the capillary. If the hydrostatic pressure is greater than the osmotic pressure, fluid will move out of the capillary. If the osmotic pressure is greater than the hydrostatic pressure, fluid will move into the capillary.

Lymphatic drainage

The lymphatic system is a network of vessels that helps to drain fluid from tissues back into the bloodstream. The lymphatic vessels are located near the capillaries, and they help to collect fluid that has leaked out of the capillaries. The lymphatic system is also responsible for transporting immune cells and waste products away from tissues.

In a sprained ankle, the Starling forces and the lymphatic drainage system are both disrupted. This can lead to the accumulation of fluid in the ankle, which can cause swelling and pain.
