Lymphatic System
The Lymphatic System
And Immunity The cells, tissues, and organs of the lymphatic system play a central role in the body’s defenses against a variety of pathogens, or disease-causing organisms.
Acts against environment hazards, various pathogens, and internal threats.
Lymphocytes (primary cell) are vital to or overcoming infection and disease.
Lymphocytes respond to invading pathogens, abnormal body cells, and foreign proteins. They act to eliminate these threats or render them harmless through a combination of physical and chemical attacks.
Immunity is the ability to resist disease and infection.
There are two forms of immunity that work independently or together.
- Innate (nonspecific) immunity
- Adaptive (specific) immunity
The body has several anatomical barriers and defense mechanisms that either prevent or slow the entry of infectious organisms, or attack them if they do enter. These mechanisms are called innate (nonspecific) defenses because they do not distinguish one threat from another. These are defenses present at birth.
Lymphocytes provide an adaptive (specific) defense known as an immune response. Lymphocytes respond specifically, if a bacterial pathogen invades peripheral tissues lymphocytes organize a defense against that particular bacterium. Developed over time.
All the cells and tissues involved in producing immunity are considered part of the immune system. This physiological system not only includes the lymphatic system but also parts of the integumentary, cardiovascular, respiratory, digestive, and other systems. The Lymphatic System Components
Lymph – Originates as interstitial fluid. Resembles plasma but contains less suspended proteins.
Lymphatic Vessels or Lymphatics - Begin as lymphatic capillaries in the peripheral tissue, connect to form into larger lymphatics (with valves) and then into lymphatic ducts.
Lymphatic Ducts - Collect the lymph and returns it into circulation.
Lymphoid Tissues –
