What are the differences between a specific and a nonspecific immune response quizlet?
nonspecific immunity are things that protect the body from various bacterias, viruses, and pathogens. These include the first and second line of defense, such as the skin, fever( body gets hot as an attempt to kill the pathogen). Specific immunity are things that protect the body from specific pathogens.
What is a nonspecific immune response?
INNATE IMMUNITY. Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body.
Which is a specific immune response?
The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with. This is also known as an “acquired” (learned) or specific immune response.
Why is it called non specific immunity?
The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system.
Is fever specific or nonspecific?
Fever. Fever is considered a nonspecific defense mechanism because it develops in response to numerous traumas. Fever is initiated by circulating substances calledpyrogens, which affect the brain's hypothalamus and cause the latter to raise the temperature.
Which of the following is an example of specific immunity?
Which of the following is an example of specific immunity? The person produces antibodies in response to being injected with antigens.
What cells are involved in specific immune response?
Targeted responders: cells known as lymphocytes, which target invaders by producing proteins called antibodies that target specific antigens. This process is a targeted or specific immune response. Each antigen that enters your body has an antibody targeted to it.
What are examples of specific defenses?
There are two types of specific defense. These include cell-mediated immunity and antibody-mediated immunity. Cell-mediated immunity occurs when T-lymphocytes (T-cells) become activated by exposure to pathogens. Activated T-cells then attack pathogens directly.
What is an example of nonspecific immunity?
NON SPECIFIC DEFENSES: Skin and Mucous membranes, antimicrobial chemicals, natural killer cells, phagocytosis, inflammation and fever.
What are 2 types of nonspecific immunity?
there are two types: nonspecific, innate immunity and specific, acquired immunity. Innate immunity, with which an organism is born, involves protective factors, such as interferon, and cells, such as macrophages, granulocytes, and natural killer cells, and its action does not depend on prior exposure to a pathogen.
What are three types of nonspecific immunity?
Humans have three types of immunity — innate, adaptive, and passive: Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection. For example, the skin acts as a barrier to block germs from entering the body.
What are some non specific defenses?
Nonspecific defense mechanisms include the skin, mucous membranes, secretions, excretions, enzymes, inflammatory responses, genetic factors, hormonal responses, nutritional status, behavior patterns, and the presence of other diseases.
What is specific immunity and nonspecific immunity?
Non-specific immunity is generalized immunity that all humans are born with, including barriers, like skin, chemicals, like stomach acid and tears,...
Is skin an example of specific immunity?
No. Skin is an example of non-specific immunity. Non-specific immunity is the body's generalized and ongoing defense system to protect from pathogens.
What are the four types of specific immunity?
The four types of specific immunity are vaccine acquired, disease acquired, naturally acquired, and curative. Natural immunity is passed down gener...
