Module 9 - Overview and Terminology
- lymphatic system has several main functions.
- elaborate network of lymphatic vessels is involved in returning the small amount of fluid
that is filtered out of capillaries at the periphery back into circulation. This is very
important for maintaining fluid balance.
- Specialized lymph vessels called lacteals are responsible for absorbing fat from the
digestive system and transporting it to the liver for processing. The lymphatic system
also plays a significant role in the defense of our body against microorganisms like
bacteria and viruses.
The ability of our body to resist damage from microorganisms is called immunity. We will look
at several types of immunity that play a role in protecting our body from harm.
Innate (non specific) immunity utilizes barriers like skin, chemical enzymes in saliva and tears,
as well as white blood cells in the blood and lymph system to destroy foreign substances.
Adaptive (specific) immunity utilizes antibody proteins that are generated specifically to
defend against a type of foreign invader our body has encountered before. Adaptive immunity
prepares our bodies for future encounters by creating memory cells that quickly respond the
next time the same type of foreign invader enters our body.
1. lymphocytes (Section 11.4): Nongranulocytic white blood cell involved in the immune
system; there are several types of lymphocytes with diverse functions, including
antibody production, allergic reactions, graft rejections, tumor control, and regulation
of the immune system.
2. Basophils (Section 11.4): White blood cell with granules that stain purple with basic
dyes; promotes inflammation and prevents clot formation.
3. lacteals (Section 14.1): Lymphatic vessel in the wall of the small intestine that carries
chyle from the intestine and absorbs fat.
4. lymph nodes (Section 14.2): Encapsulated mass of lymphatic tissue found along
lymphatic vessels; filters lymph and produces lymphocytes.
5. innate (Section 14.3): [innate immunity] Immune system response that is the same
on each exposure to an antigen; there is no ability to remember a previous exposure
to a specific antigen.
6. chemotaxis (Section 14.4): the ability of cells to move toward pathogens or sites of
tissue damage.
7. phagocytosis (Section 14.4): Ingestion and digestion by cells of substances, such as
other cells, bacteria, cell debris, and foreign particles.
8. inflammation (Section 14.4)
