Q

Functions of the Lymphatic System

A
  1. Absorb fats and fat-soluble vitamins through the lacteals of the small intestine
  2. Remove waste products from the tissues and cooperate with the immune system in destroying invading pathogens.
  3. Return filtered lymph to the veins at the base of the neck.

Q

Lymphatic vessels

A

They eventually join together to form two ducts. Each duct drains a specific part of the body and returns the lymph to the venous circulation.

Interferons

A

Activate the immune system, fight viruses by slowing or stopping their multiplication, and signal other cells to increase their defenses.

34
Q

Interleukins

A

Directing B and T cells to divide and proliferate.

35
Q

Tonsils

A

Three masses of lymphoid tissue that form a protective ring around the back of the nose and upper throat.

Antibody

A

A disease fighting protein created by the immune system in response to the presence of a specific antigen.

42
Q

Immunoglobulins

A

Bond with specific antigens in the antigen-antibody response.

43
Q

Natural immunity

A

Resistance to disease present without the administration of an antigen or exposure to a disease.
