Immune Function, Inflammation & Infection

Immune Response

collective, coordinated response of the cells and molecules of the immune system

What are the types of immune defenses?

Innate and adaptive

What is the innate immunity?

natural resistance in when a person is born

What is adaptive immunity?

the second line of defense. It responds later the innate but its more effective

What are lymphoid organs connected by?

netwrok of lymph channels, blood vessels,and capillaries

What cells are invloved in the innate immunity?

epithelial cells

How do we develop aquired immunity

through the actions of B and T cells

Inflamation response

bodys protective reaction to injury, disase, or damage to tissues

What are the 3 stages of the inflammatory response?

warmth, pain, and decreased function/ pain at the site

What are the memory cells associated adaptive immunity

T lymphocytes and B lymphocytes

What is humoral immunity

What is IgG

most abundant antibody, activates complement system , and crosses placenta

What is IgA?

found in tears, saliva, secretions and it limits amount of attachment to cells

What is IgM

verifies if blood types do not match

What is IgD

antigen receptor on B cells

What is IgE

Almost in every allergic response and involves in inflmation

What is infection

invasion and multiplication of microrganisms in a body tissues

What is acute inflamation?

short duration last couple of mins to dates

Chronic inflammation

progressive inflamation and keeps adding to it; its much longer depending on tissue damage

What are the white blood cells for inflammation?

granulocytyes, neutrophils,eusophils,basophils, mast cells

What is the thymus?

helps mature the T lymphocytes

What is the lymphatic system?

collects fluid that builds up in tissue throughout the body

What are the functions of fluid?

Help maintain fluid balance, filters and check lymph for pathogens, filters blood of dead and damaged red cells, and produced white blood cell calued lymphocyte

What are the white blood cells?

found in the skin, blood, tissue of the body and they seek pathogens and destroy cellular debris

What are phagocytes?

engulf and digest pathogens and they also injest dead cells

What are the four a major types of phagocytes?

Neutrophils, eosinophils, basophils, and monocytes

What is neutrophils?

most abundant white blood cell, protection against bacterial infections, and when they are signaled they leave the blood stream to fight infection in body tissue.

What is eosinphil?

migrate to the sites of infection to destroy parasites and control immune reponse with allergy and asthma

Basophils

contain histamine and cruicial to allerguc reactions

What is histamine

dilate blood vessels

Vasodilation

increase blood flow and make it easier for other white blood cells to move out of the blood stream

What are monocytes

white blood cells found in blood stream

What are the 3 major types of lymphocytes>

B lymphocytyes, T Cells, and natural killer cells

What is humoral immunity?

a specific immune response that involves the use of antibodies and remeber specific pathogens and protect the body when the pathogen tries to come again

What is cell mediated immunity?

a specific immune response that helps destroy abnormal or infected cells without antibodies
