Question

Describe the location of the spleen and explain its functions. If the spleen is removed, what organs will compensate for its functions? (pp. 327-328)

Short answer

2. What are the main functions of the spleen? 3. What organs can compensate for the spleen's functions if it is removed?

Step-by-step solution

Location of the spleen

The spleen is located in the upper left abdomen, just below the diaphragm and behind the stomach. It's a part of the lymphatic system and is roughly the size of a fist.

Functions of the spleen

The spleen has several important functions. It acts as a filter for blood, removing old or damaged red blood cells and recycling them to create new ones. The spleen also stores platelets and white blood cells, which are vital for the immune system. Additionally, the spleen plays a role in identifying and eliminating harmful bacteria and other pathogens from the bloodstream.

Organs that compensate for the spleen's functions if removed

If the spleen is removed, several organs and systems in the body will compensate for its functions. The liver, in particular, plays a major role in taking over the spleen's filtering and blood cell recycling functions. The bone marrow, where blood cells are created, will also be more active in producing new cells when the spleen is not present. In addition, other parts of the lymphatic system, such as the lymph nodes and the thymus, will help support the immune function normally associated with the spleen.
