Study Notes
Osmolarity and Osmoregulation
- Osmolarity measures the concentration of solutes in a solution.
Osmoregulation in Multicellular Organisms
- The extracellular fluid of a multicellular organism includes blood plasma, lymph, and interstitial fluid.
Osmosis
- The main factor that determines the direction of passive water movement in osmosis is the concentration of solutes.
- In osmosis, water moves from an area of high concentration to an area of low concentration.
Aquaporins
- The primary function of aquaporins in osmosis is to facilitate the transport of water molecules across cell membranes.
Importance of Osmoregulation
- The role of osmoregulation in living things is to maintain proper cellular osmotic balance, which is essential for cellular functions and overall health.
