Biofluid dynamics is also an example of a biological fluid. Types of Fluids Fluids can be classified into four basic types. They are: An Ideal Fluid is a fluid that has no viscosity, means it will offer no resistance, pragmatically this type of fluid does not exist. It is incompressible in nature. Real fluids are compressible in nature. They offer some resistance and thus have viscosity. All Fluids existing are real fluids. A Newtonian Fluid is a fluid whose viscous shear stresses (acting between different layers of fluid and between the fluid layer and surface over which it is flowing) are directly
Innate resistance to HIV occur, which leads to the possibility of CTLs only being an indicator of other genetic resistances towards HIV, such as immunoglobulin A responses within vaginal fluids. Chimpanzees in African countries have been found to develop AIDS at a slower rate than humans. This resistance is not due to the primate's ability to control the virus in a manner that is substantially more effective than humans, but rather because of the lack of tissues created within the body that typically progress HIV to AIDS. The chimpanzees also lack CD4 T cells and immune activation that is required for the spread of
