An animal must defend itself from foreign intruders, such as bacteria, viruses and other pathogens. It must also deal with abnormal cells that periodically appear in the body.Two cooperative defense systems that counter these threats have evolved.
* Non specific resistance * the immune system ans specific defense In the non specific system the body does not distinguish one infectious agent from another. This includes two lines of defense.
# external: consists of epithelial tissue eg skin, mucous membranes, # Internal: It is triggered by chemical signals and employs antimicrobial proteins and phagocytic cells that indiscriminately attack any invader that penetrates the bodys outer barriers.
The immune system responds specifically to the particular type of invader. This includes production of specific defense proteins called antibodies.It also involves the participation of several different types of cells that are decendents of white blood cells called lymphocytes. The immune sytem constitutes a third line of defense, which comes into play simmultaneously with the second.
What else can I help you with?
Are non specific defence mechanisms more effective than specific defense mechanisms if so why?
Non specific defense mechanisms are more effective because they work against all bacteria and viruses. Examples are skin or tears. Specific defense mechanisms like antibodies work against one type of bacteria or virus. They're needed if a pathogen gets past the nonspecific defense mechanisms.
What role do cytokines, proteins that regulate immune responses, play in the body's defense mechanisms?
Cytokines are proteins that help regulate the immune system by signaling between cells. They play a crucial role in coordinating the body's defense mechanisms, such as inflammation and immune responses, to fight off infections and diseases.
Eukaryotes show which kinds of control mechanisms is it transcriptional transcript processing translational post translational or all of these?
Eukaryotes exhibit control mechanisms at all levels, including transcriptional, transcript processing, translational, and post-translational regulation. These mechanisms work together to finely regulate gene expression and protein production in response to various internal and external signals.
What is meant by specific defense?
Specific defense refers to the immune response that targets a specific pathogen or foreign substance, utilizing specialized immune cells and proteins tailored to recognize and eliminate that particular threat. This type of defense provides a more targeted and efficient response compared to innate immunity.
What are the primary functions of ego defense mechanism?
We can't live without our ego. If our ego is hurt, the whole psychosomatic machine collapses and we need to resurrect. This will take a long time once again to survive. So Nature has given us something called ego defense mechanism. With the help of this mechanism, we can protect our ego from being destroyed. Avoidance, blame, aggression, criticism, etc. are some of the common actions by which we defend our ego.
Why must your bodies have defense mechanisms?
Those defense mechanisms are designed to protect you from diseases and infections.
What are the ligers defense mechanisms?
the ligers are a cross between a lion and a tiger their defense mechanisms are their teeth and their claws
Why should you avoid using defense mechanisms too frequently?
Defense mechanisms are part of the unconscious. Therefore one cannot really control what mechanisms he/she uses.
What are the starfish's defense mechanisms?
Pooping on you
What is defense mechanisms?
A defense mechanism is a coping strategy that protects you from difficult feelings.
What are the howler monkeys defense mechanisms?
choclatre
What is a monkeys defense mechanisms?
sucking dick
What defense mechanisms does the bald eagle have?
Its talons.
What defense mechanisms does the camel have?
running away of it
Can defense mechanisms exist when one is delusional?
Yes, but they tend to be the primitive defense mechanisms; denial, minimization, rationalization and projection. Higher order defense mechanisms, such as humor, altruism, and sublimation, or even defenses such as intellectualization, are not operative, however, in delusional/psychotic states.
What are the defense mechanisms that the panama snowcap bird has?
The Panama snowcap bird has a few defense mechanisms. It is very tiny and fast, so it can escape predators easily.
What defense mechanisms does?
Defense mechanisms are psychological strategies used unconsciously to protect oneself from anxiety or distress. Common defense mechanisms include denial, projection, repression, and rationalization. These mechanisms help individuals cope with threatening thoughts or impulses.
