Anatomy & Physiology of the Spleen

The video provides an overview of the spleen, detailing its location, blood supply, and functions. It explains the spleen's role in degrading old red blood cells and platelets, and its ability to mount an immune response against pathogens in the blood. The structure of the spleen is discussed, highlighting the red and white pulp, which are responsible for filtering blood and initiating immune responses. The video concludes with a brief mention of the next topic, the appendix.

Where is the spleen located in relation to the liver?

• On the left side of the abdomen

• Below the liver

• Above the liver

• On the right side of the abdomen

What is the primary function of the spleen related to red blood cells?

• Degradation of old red blood cells

• Transport of red blood cells

• Storage of red blood cells

• Production of red blood cells

How does the spleen differ from lymph nodes in terms of what it monitors?

• The spleen monitors blood, while lymph nodes monitor lymph

• The spleen monitors lymph, while lymph nodes monitor blood

• Both monitor blood

• Both monitor lymph

What role do white blood cells in the spleen play?

• They store nutrients

• They produce antibodies

• They monitor blood for pathogens

• They transport oxygen

What is the primary function of the red pulp in the spleen?

• To produce hormones

• To produce white blood cells

• To filter and degrade old red blood cells and platelets

• To store iron

Which cells are rich in the lymphoid follicles of the white pulp?

• Red blood cells

• Macrophages

• Platelets

• B-cells

What is the function of the periarteriolar lymphoid sheaths (PALS) in the spleen?

• They store red blood cells

• They are rich in T-cells and participate in immune responses

• They produce platelets

• They filter lymph
