GENERAL HISTOLOGY

Detailed explanation-1: -Lymph nodes filter lymph, and the spleen filters blood. The lymph node and spleen are known as the secondary lymphoid organs or the peripheral lymphoid organs. The pathogenic microorganisms and other foreign antigens are filtered from lymph by lymph nodes and from the blood by the spleen.

Detailed explanation-2: -False, the spleen filters blood, whereas lymph nodes filter lymph.

Detailed explanation-3: -The spleen also removes unhealthy, old, and misshapen red blood cells from circulation. Red blood cells carry oxygen throughout the body and remove carbon dioxide (a waste product). These disc-shaped cells are filtered by the spleen based on their physical characteristics.

Detailed explanation-4: -They filter out viruses, bacteria, and fungi that can cause illnesses. Most lymph nodes are in clusters in the neck, armpit, and groin area. They’re also found along the lymphatic pathways in the chest, abdomen, and pelvis, where they filter blood.
