Q

Lymph

A

Clear watery fluid that surrounds body cells and flows in a system of lymph vessels throughout the body.

  • Originates in blood
  • Rich in lymph capillaries and vessels
  • Flows in lymph capillaries and vessels.
  • Flows through lymph nodes and lymphatic organs (liver, spleen, thymus, and nodes)
  • Absorb lipids in the intestine.

Lymphatic System Functions

A

Transports proteins and fluid that have leaked, back to the bloodstream
Lymphatic vessels absorb lipids from intestines and transport them to the bloodstream
Lymphocytes and monocytes protect the body by mounting a cellular attack on foreign cells and organisms.

Q

Thymus Gland

A

Provides immunity in fetal life and in early years of growth.

Makes cells immunocompetent in early life

Early removal from an animal impairs its ability to make antibodies and produce cells to fight antigens

Q

Immune System

A

Leukocytes: neutrophils, monocytes, and macrophages

Lymphoid organs: lymph nodes, spleen, thymus gland, tonsils, and adenoids; produce lymphocytes and antibodies

Immunity: the body’s ability to resist foreign organisms and toxins that damage tissues and organs; can be natural or adaptive

Q

Natural and Adaptive Immunity (cont’d)

A

B lymphocytes are responsible for humoral immunity.
- Originate in bone marrow from stem cells

  • B cells produce antibodies after exposure to specific antigens (viruses and bacteria)
  • B cell matures into plasma cell that produces antibodies called immunoglobulins to block the effects of antigens

Q

Natural and Adaptive Immunity (cont’d)

A

T lymphocytes are responsible for cell-mediated immunity; does not involve antibodies
- Cytotoxic T cells (T8 cells) attach to and directly kill antigens.

  • Other T cells secrete cytokines (interferons and interleukins) that help cells respond to antigens.
  • Helper T cells promote antibody synthesis by B cells and stimulate other T cells.
  • Suppressor T cells (regulatory T cell or Tregs) inhibit B and T cells and prevent them from attacking the body’s own good cells.

Q

Natural and Adaptive Immunity (cont’d)

A

Dendritic cells
- Dendritic cells are a macrophage derived from monocytes.

  • They recognize and digest foreign antigens.
  • They present antigens on the surface to stimulate B and T cells.
  • They transfer immunity by exposing dendritic cells in culture; then transfuse them and get them to stimulate T and B cells.

Q
  • Immunotherapy Examples
A
  • Vaccines: contain antigens from the patient’s tumor cells; stimulate the patient’s own T cells to recognize and kill the cancerous cells; active immunotherapy
  • Dendritic cells: cultured and exposed outside the body and reinfused
  • Monoclonal antibodies (MoAb): multiple copies of cells or genes that kill tumor cells; passive immunotherapy
