BIOB34H3 Lecture Notes - Extracellular Fluid, Fluid Compartments, Osmoregulation
Document Summary
Slide 2 body fluid compartments: closed circulatory system. Osmoregulation is about regulating various aspects of the body fluids of animals. The animal is separated from its external environment. The external environment refers to either freshwater, marine, or terrestrial. These are the 3 major types of environment animal physiologists usually talk about. The animal is separated from the external environment by the integument. The integument is the boundary between the environment and the animal, so for animals this would be the skin. The most important body fluid is probably the intracellular fluid, the fluid that"s found within the cells. Everything is geared towards assuring that the icf is well regulated to make metabolism efficient. What could affect the composition of icf: one thing is water moving either into the cell from ecf, or water from the icf moving out to the ecf. The icf is separated from two kinds of extracellular fluid.
