The human body contains hundreds of different types of cells. The exact number is still being researched, but it's estimated to be between 200 and 300.

Some of the most common cell types include:

* Nerve cells (neurons): Responsible for transmitting information throughout the body.

* Muscle cells: Enable movement and contraction.

* Blood cells: Transport oxygen, fight infections, and help with clotting.

* Skin cells: Protect the body from the environment.

* Bone cells: Form and maintain bones.

* Fat cells: Store energy and provide insulation.

* Liver cells: Filter blood and produce essential proteins.

* Kidney cells: Filter waste products from the blood.

* Pancreatic cells: Produce hormones and digestive enzymes.

* Intestinal cells: Absorb nutrients from food.

Each cell type has a unique structure and function, working together to maintain the body's health and well-being.
