Homeostasis refers to an organism"s ability to regulate various physiological processes to keep internal states steady and balanced. These processes occur mostly without ones conscious awareness. There are three main types of homeostatic regulation that happen in the body. They are thermoregulation, osmoregulation, chemical regulation.
BODY FLUID COMPARTMENT
In this eLearning module you will learn about Body fluid compartments, The adult human body is made up of 60% water and is divided into extracellular, intracellular fluid, transcellular fluid, plasma volume, red cell volume and interstitial fluid volume. Extracellular fluid is present outside the cells and makes up ⅓ of the total body water. Intracellular fluid is present inside the cells and makes up ⅔ of the total body water.
TRANSPORT ACROSS THE MEMBRANE
In this eLearning module you will learn about Transport across the membrane. All cells are enclosed by a cell membrane, which is selectively permeable. Molecules can move into or out of cells by diffusion and active transport. The chemical structure of the cell membrane makes it remarkably flexible, the ideal boundary for rapidly growing and dividing cells. Transport of these vital substances is carried out by certain classes of intrinsic proteins that form a variety of transport systems.
