Lab 12 The Lymphatic System BIO202L
Student Name: Mackenzie Gasperich
Access Code (located on the lid of your lab kit): AC- FTCO54R
Pre-Lab Questions:
1. In what areas are lymph nodes clustered? Why is this desirable?
Lymph nodes cluster in the cervical region of the neck, axillary region of the underarms, and the inguinal
region near the groin area. This is desirable because
2. Explain how the flow of lymph is controlled through lymphatic vessels.
The flow of lymph is controlled by the contracations of the angions in the lymphatic vessels. The smooth
muscles in the walls of the vessels cause this contraction. The prevention of backward flow is due to the
valves in the lymphatic vessels.
Experiment 1: Examining the Microscopic Anatomy of Lymphatic System
Post-Lab Questions
1. Label the items in the following slide pictures based on your observations.
A- Lymphoid follice
B- germinal centers
C- connective tissue capsule
D- medullary cords
E- Red pulp
F- white pulp
