White Blood Cells: Eosinophil

The white blood cell is a very important cell in the human body. Without it, there would be no line of defense in our body and we would get sick very easily, which would be detrimental to our health. There are many types of white blood cells and eosinophil is just one of them. Eosinophil is a type of granulocyte and a specialized cell of the immune system. They are about three times the size of a red blood cell.

They do not have the same organelles as the typical eukaryotic cell as they have a two-lobed nucleus and a cytoplasm filled with large granules that contain digestive enzymes. 

This cell is mostly found in loose connective tissues like glands, reproductive organs, and the digestive tract. The main purpose of this cell is to destroy parasitic worms like pinworms, hookworms, and tapeworms. They release the digestive enzymes onto the surface of the worms, destroy them, and breaks down their remains. They also demolish invading germs, creates an inflammatory response especially for allergies and asthma, and has a role in forming organs. But, these jobs require the help of other red blood cells. White blood cells are considered a connective tissue as they are the site of immune responses.
