Study Notes
Functions of Albumin
- Albumin helps maintain oncotic pressure between blood vessels and tissues, preventing fluid from leaking out of blood vessels and into tissues.
- Without albumin, fluid would accumulate in tissues, leading to Edema (swelling due to excess fluid).
- Albumin's colloid nature, along with globulins, keeps fluid within blood vessels.
- The oncotic pressure within capillaries is greater than the pressure in the surrounding interstitial space.
- Hydrostatic pressure pushes fluid out of the capillary, while oncotic pressure pulls it back in.
- The balance between these two pressures determines the direction of fluid movement.
