Haemal node

Haemal Node

The Haemal Node is a type of lymph node that is found in the circulatory system of certain animals. It is particularly prevalent in the ruminant species, such as cows and sheep. The primary function of the haemal node is to filter the blood and remove any foreign substances that may be present.

Etymology

The term "haemal" is derived from the Greek word "haima", which means blood. The "node" part of the term refers to the node-like structure of this part of the circulatory system.

Function

The haemal node functions in a similar way to a regular lymph node. It filters the blood and removes any foreign substances, such as bacteria, viruses, and other potentially harmful particles. This helps to keep the blood clean and free from infection.

Location

Haemal nodes are typically located near the major blood vessels in the body. They are particularly common in the abdomen and thorax of ruminant animals.
