1. The pancreas - functions as exocrine + endocrine gland. - has 2 groups of cell in the pancreas. - α & β-cells in the islet of Langerhans play (major role in blood glucose concdntration). - α-cells - secrete glucagons - β-cells - secrete insulin into blood capillaries. α & β-cells in the islet of Langerhans 2. Blood glucose level rises↑à due to carbohydrate breakdown. 3. Insulin + glucagons have opposite effects. 4. Insulin: - secreted by β-cells (when glucose↑ level increases)…

What is the Difference Between Osmotic Pressure and Oncotic Pressure? Oncotic pressure is the contribution made to total osmolality by colloids. Osmotic pressure
Osmotic Pressure: The pressure that must be applied to a solution to prevent osmotic movement across a semipermeable membrane.

Starling forces consist of hydrostatic pressure and osmotic (oncotic) pressure. Hydrostatic pressure is the pressure of the fluid within the blood vessel, while osmotic pressure is the “sucking” pressure drawing water toward solutes. Oncotic pressure is osmotic pressure due to proteins. Hydrostatic pressure forces fluid out at the arteriolar end of a capillary bed; oncotic pressure draws it back in at the venule end. Prevents edema (buildup of interstitial fluid from hydrostatic pressure).
The movement of water molecules through a semi permeable membrane from the region of higher water concentration to the region of le...
