Verified step by step guidance

Understand the function of the spleen in the circulatory system. The spleen acts as a filter for blood, removing old and damaged red blood cells.

Recognize that the spleen contains specialized structures called sinusoids, which trap and fragment aging red blood cells.

Learn about the role of macrophages in the spleen. These cells engulf and break down the fragments of red blood cells, recycling components like iron.

Differentiate the spleen's function from other organs listed, such as the liver, kidneys, and intestines, which have different roles in the body.

Conclude that the spleen is the primary organ responsible for trapping and fragmenting aging red blood cells, based on its anatomical and physiological functions.
