Distinguish between natural immunity and artificial immunity?
Natural immunity is acquired through natural exposure to an infectious agent, or through maternal antibodies passed from mother to child. Artificial immunity is acquired through vaccines or deliberate exposure to an infectious agent, without experiencing the full illness. Both types of immunity result in the body producing antibodies to protect against future infections.
What gland plays a major role in the development of immunity?
The thymus gland plays a major role in the development of immunity. It is responsible for the maturation of T cells, which are a type of white blood cell that plays a critical role in the immune response.
Compare and contrast active and passive immunity and give a rea life example?
Active immunity is produced by the body's immune system in response to exposure to a pathogen or vaccine, leading to the production of memory cells for long-term protection. Passive immunity is acquired from an external source such as mother to infant transfer of antibodies or through medical intervention, providing immediate but short-lived protection as it does not generate memory cells. A real-life example is receiving a vaccination (active immunity) to develop immunity to a specific disease compared to receiving pre-formed antibodies through a blood transfusion (passive immunity) for immediate but temporary protection.
Where do antibodies come from in the active immunity process?
Antibodies are produced by B cells (a type of white blood cell) in response to the presence of a specific antigen, such as a virus or bacteria. Once the B cell recognizes the antigen, it matures into plasma cells that release antibodies into the bloodstream to target and neutralize the invading pathogen. This process is part of the active immunity response, where the immune system generates its own protection against future infections.
Is everyone born with natural immunity?
No, not everyone is born with natural immunity. Immunity can be innate, acquired through exposure to diseases, or acquired through vaccinations. A person's immune system can also be compromised due to various factors such as genetics, diseases, or medications.
Two blood cells chiefly responsible for the acquired immune response?
Lymphocytes
What type of blood cell is responsible for immunity?
White blood cells, specifically lymphocytes, are responsible for immunity. They play a key role in recognizing and defending the body against foreign invaders like viruses, bacteria, and other pathogens.
Do white blood cells initiate clotting process?
No, platelets and factors in the plasma are responsible for clotting. White blood cells mediate immunity.
What is pooled serum human globulin and what type of immunity might this confer?
Pooled human serum globulin is antibodies (or antitoxins) found in our blood. When administered to a patient after exposure to Hepatitis A it is a type of Artificially acquired passive immunity.

Artificial immunity is acquired through vaccines or deliberate exposure to an infectious agent, without experiencing the full illness. Both types of immunity result in the body producing antibodies to protect against future infections.
What are the blood cell?
White blood cells ( WBC), Red blood cells( RBC), and finally platelets. White blood cells are the cells that are responsible for the immunity of the cells, while red blood cells contain the oxygen containing pigment heamoglobin, and platelets are fragments of cells that are responsible for clotting.
What are The cells directly responsible for cellular immunity?
T cells are the cells directly responsible for cellular immunity. They recognize infected cells or aberrant cells and work to eliminate them from the body.
What is the lymphatic system responsible for?
The lymphatic system picks up fluid leaked from blood vessels and returns it to the blood; disposes of debris in the lymphatic stream; and houses white blood cells involved in immunity.
What cells responsible for immunity?
Immune cells responsible for immunity include white blood cells such as T cells, B cells, natural killer cells, and phagocytes like macrophages and neutrophils. These cells work together to detect and eliminate pathogens, infected cells, and other foreign substances to protect the body from infections and diseases.
What is blood titer?
blood titre is found by doing a blood test for immunity. the titre shows the level of immunity against something (i.e. Rubella)
