The body's nonspecific defiance against invading pathogens is known as innate immunity and includes the following:
mechanical barriers and surface secretions
1. The intact skin and mucous membranes of the body. These provide a high degree of protection against pathogens.
2. The sebaceous secretions and sweat of the skin contain bactericidal and fungicidal fatty acids that can kill bacteria and fungi.
3. Normal bacterial flora of the skin may produce various antimicrobial substances such as bacteriocines and acids.
Humoral defence mechanisms
1. Lysozyme. This is an enzyme found in most tissue fluids apart from cerebrospinal fluid, urine, and sweat. It can kill bacteria.
2. Interferon. Inhibits viruses from replicating
3. Complement. This is a heat labile serum that can destroy gram-negative bacteria.
The transpiration pull is just one of the mechanisms that explain the movement or translocation of water in plants, particularly water ascent in tall trees. There is no single exacting explanation as yet for the ascent of water but several theories have been proposed. Of these, the one which has gained wide support is the cohesion-tension theory which recognizes the crucial role of<span> transpiration pull</span><span> as a driving force. These theories are briefly described below.. I dont know maybe this might be helpful</span>
