Your Lab Summary: What were the most significant 2 or 3 concepts you learned while doing this Lab?
Exercise 1: Microscopic Anatomy of Lymphatic Structures
A. How are lymph, lymphatic vessels and lymph nodes related? a. They are related because the lymphatic system is a network of tissues and organs. It is made up mainly of lymph vessels, lymph nodes and lymph. Lymph vessels, which are different from blood vessels, carry fluid called lymph throughout your body. Lymph contains white blood cells that defend you against germs.
B. What are the two major functions of the lymph nodes?
a. The main function is to act as a drainage system by absorbing and expelling proteins, dead cells, bacteria and other waste products from the body. b. They are also a major part of the immune system, as they produce antibodies and lymphocytes.
C. What are the two functions of the spleen?
a. They break down red blood cells and make antibodies.
D. What is the function of the tonsils?
a. They function to guard against inhaled and ingested pathogens. They have deep pits that catch bacteria and food debris.
E. What are the structural similarities found in lymph nodes, spleen and tonsils? a. They all have a capsule, they are rounded organs with an internal parenchyma of lymphoid cells, they are placed strategically about the body in order to maximally filter air/blood.
