Lymphatic System

  • Anatomy- This system includes lymph, lymph nodes and vessels, leukocytes, tonsils, adenoids, thymus. and spleen.
  • Physiology- It is responsible for defending against disease-causing agents.
  • An antigen is any substance that elicits an immune response.
Types of Immunity
  • Passive Immunity is immunity to particular antigens as a result of genetic traits. In natural passive immunity, antibodies are passed from a mother to a child.
  • Active Immunity is produced by contact with an antigen. A common example of active immunity is vaccines. They are used to expose the body to a particular antigen.
Lymphatic System
  • This system contains structures involved in the transfer of lymph between tissues and the blood stream.
  • It includes the lymph and the nodes and vessels.
  • The largest body of lymphoid tissue in the human body is the spleen. The spleen resembles a very large lymph node.
  • The lymphatic system is important to the body’s defense mechanisms.
    1. It filters out organisms that cause disease, produces certain white blood cells, and generates antibodies.
    2. It is also important for the distribution of fluids and nutrients in the body because it drains excess fluids and protein so that tissues do not swell up.
Lymph
  1. A milky fluid
  2. Contains a type of white blood cells, called lymphocytes, along with proteins and fats
  3. It is through the actions of this system that our body is able to fight infection.
  4. Lymph plays an important role in the immune system and in absorbing fats from the intestines.
  5. There are more than 100 lymph nodes in the human body; they are mainly found in the neck, groin, and armpits.
