Explanation:
The main function of the plasma membrane is to protect the cell from its surroundings. Made of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules it also regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. Membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors, which then trigger intracellular responses. Some viruses, such as Human Immunodeficiency Virus (HIV), can intercept these receptors to get into the cells, causing infections.

Physiology
[ Explanation ]
Physiology is the study of the functions and mechanisms in which your body works. It is how your body keeps you alive and how each part functions differently. It is how your organs, organ systems and cells keep you alive. They all perform different functions, but they all work together. It is almost like a car. Each part is different. The brakes stop the car, the gas makes the car go, this does this and that does that. However, even though they are all different, they all have one job; to make the car go from one location to the other. Physiology is the study of how each organ or cell does it's job. They explore deeper and reveal it's actual function.
