BIOS255 Week 4 Lymphatic System
Learning Objectives:
State the components and functions of the lymphatic system
Trace lymphatic drainage through the major vessels of the lymphatic system.
Identify the mechanisms that cause movement of lymph through the lymph vessels.
Introduction:
The lymphatic system consists of lymphatic fluid, lymphatic vessels, lymphatic tissue, and
lymphatic organs located throughout the tissues of the body. It functions to drain excess
interstitial fluid from the tissues, to initiate an immune response against disease by producing
and transporting lymphocytes, and to transport dietary lipids absorbed by the gastrointestinal
tract into the blood. Lymphatic capillaries extend throughout the tissues of the body among
blood capillary beds. Interstitial fluid, similar in composition to blood plasma, leaches from the
blood capillaries into the surrounding tissue, bathing the cells and supplying each one with
nutrients, oxygen, and water while also removing waste, carbon dioxide, and water. Around 30
liters of fluid enter the arteriolar end of capillaries every day, but only 27 liters return to the
venous capillaries. The lymphatic system collects the missing 3 liters from the interstitial space
and returns it to the venous system. Let’s explore this system that can be found in so many
different places and perform multiple roles!
Assignment
Part 1: Complete the activities on Anatomy.TV for the Lymphatic System and Immunity:
Introduction, Vessels and Circulation, Organs and Tissues.
To access Anatomy.TV: Resources tab>Library>Library Resources-Database A-
Z>Anatomy.TV>Titles(default tab): Choose Lymphatic system and Immunity>choose
assigned sections
You will then work through the material and activities by scrolling down on the right. This
will allow you to see and work through all activities for that section.
As you complete the lab activities, have the lab report ready to record data.
Part 2: Complete the lab report.
Lymphatic System Lab Report
1. List the 4 components of the lymphatic system described in the
introduction. (1 point; 1/4 point each)
The four components of the lymphatic system are the lymph,
lymphatic vessels, lymphatic tissue and lymphatic organs.
2. List 3 functions of the lymphatic system. (1.5 points total; 1/2 point each)
