What are some functions of the immune system?

Protects from infection.

Removes and destroys dead/damaged cells.

Identifies/destroys malignant cells.
When does pathophysiology occur?

When the body does not recognize "self" from "non-self".
Immune function.

Describe differences between Natural (innate) Immunity versus Acquired (adaptive) immunity.

WBC action: releases cell mediators such as histamine, bradykinin, and prostaglandins, and engulf foreign substances.

Inflammatory response

Intact skin, chemical barriers, and acidic gastric secretions or enzymes in tears & saliva.
What is the difference between Active and Passive immunity?
What are the 3 defenses of the immune system?
- Phagocytic immune response
- Humoral or Ab response
- Cellular immune response
Comparison of Humoral (B cells) and Cellular (T cells) Immune responses.

What are some Humoral (B cell) responses to immunity?
- Humoral (B cells):
- phagocytosis
- anaphylaxis
- allergic hay fever and asthma
- immune complex disease
- bacterial and some viral infections
Comparison of Humoral (B cells) and Cellular (T cells) Immune responses.

What are some Cellular (T cell) immune responses?
- Cellular (T cells):
- transplant rejection
- delayed hypersensitivity
- Graft-vs-Host disease
- tumor destruction
- viral, fungal, parisitic infections
Which immunity is inherited from birth?

Nonspecific/innate/natural immunity.
Which type of immunity is received after birth?

What two types of immunity does this immunity divide into? Give an example.

acquired/adaptive/specific.

Active: defenses developed by self.

Passive: developed from sources outside of the body such as via breast-feeding.
What are some immune modulators and their functions (treatments)?

interferons: antiviral & antitumor properties to treat MS and chronic hepatitis.

Colony: regulates growth & differentiation of bone marrow cells.

Monoclonal Abo: growth and production of Abo for specific pathologic organisms.
