Utilize college level grammar and professional formaṄng when completing this worksheet.
Submissions without proper formaṄng, all required photos or sufficient responses will be
rejected. Pre- lab Questions
1. The experiments in this lab cover the lymphatic system. Provide a brief overview of this
system. Include a discussion on the structures involved, its purpose and the cells
involved. (Hint: Your response should be 5-6 sentences.)
The lymphatic system is a very imporntant part of the immune and circulatory systems.
This system includes structures such as the lymph nodes, lymphatic vessels, the spleen,
thymus, and tonsils. The primary purpose of the lymphatic system is to transport lymph,
a fluid that contains white blood cells, throughout the body. This helps to remove
toxins, waste, and other unwanted material from the body. The key cells that is involved
in the lymphatic system are lymphocytes, which incluides B cells and T cells, this plays a
crucial roles in the immune defense. The lymph nodes act as filters , trapping
pathogens, while the spleen and thymus help in the developments and activation of
immune cells. Overall, the lymphatic system helps the body maintain fluid balance and
protects the body against infections.

EXPERIMENT 1: EXAMINING THE MICROSCOPIC ANATOMY OF THE LYMPHATIC SYSTEM
Introduction Questions
1. In this experiment, you will review slides containing cells from lymph nodes and from
the spleen. Describe the specific functions of these tissues. Are they similar or
different? How? Lymph nodes and the spleen are both essesntial organs in the
lymphatic and immune systems, but have slightly different fucntions. On one hand the
lymph nodes filter lymphatic fluid and trap pathogens, this allows for B and T cells to
recognize and respond to infections. While on th eother hand the spleen filters blood
rather than lymph and removes old or damaged red blood cells while at the same time
initiating immune responses to bood-born pathogens. Both tissues contains similar
immune cells but they act on different fluids, lymph in nodes and blood in the spleen.
Although they have different fucntions, both organs work to protect the body from
infection and help maintian immune surveillance.
