Chapter 20, Problem 3
The lymphoid organ that filters the blood is the ______, and the lymphoid organ that filters the lymph is the______.
Verified step by step guidance1
Step 1: Understand the role of lymphoid organs in the body. Lymphoid organs are part of the immune system and are responsible for filtering and monitoring fluids in the body, such as blood and lymph, to detect and respond to pathogens.
Step 2: Recall the primary lymphoid organ responsible for filtering blood. This organ removes old or damaged red blood cells and pathogens from the bloodstream, while also serving as a site for immune responses.
Step 3: Identify the lymphoid organ responsible for filtering lymph. This organ is distributed throughout the body and acts as a checkpoint for lymphatic fluid, trapping pathogens and debris while housing immune cells to initiate a response.
Step 4: Match the descriptions to the correct organs. The organ that filters blood is the spleen, and the organ that filters lymph is the lymph node.
Step 5: Review the anatomical locations and functions of the spleen and lymph nodes to reinforce understanding. The spleen is located in the upper left abdomen, while lymph nodes are found throughout the body, especially in areas like the neck, armpits, and groin.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Spleen
The spleen is a vital lymphoid organ responsible for filtering blood. It removes old or damaged red blood cells and pathogens, playing a crucial role in the immune response. The spleen also stores white blood cells and platelets, contributing to the body's ability to fight infections and maintain blood health.

Function of the Spleen
Lymph Nodes
Lymph nodes are small, bean-shaped structures that filter lymph fluid as it circulates through the lymphatic system. They contain immune cells that can detect and respond to pathogens, making them essential for the body's defense mechanisms. Lymph nodes swell during infections, indicating their active role in filtering and fighting off disease.

Lymphatic System
The lymphatic system is a network of vessels and organs that transport lymph, a fluid containing infection-fighting white blood cells. It plays a critical role in maintaining fluid balance in the body and is integral to the immune system. The system includes lymph nodes, the spleen, and other lymphoid tissues, facilitating the filtration of lymph and the immune response.

Textbook Question
Your friend tests her snake-wrangling skills on an eastern diamondback rattlesnake, and is bitten and envenomated (injected with the snake's venom). In the emergency department, doctors administer the antivenin CroFab, which contains antibodies to the toxins in snake venom. Is this an example of active or passive immunity? Will this confer any lasting protection to your friend?
