Types of Cells Present in a Human Body

Humans are complex organisms made up of trillions of cells, each with their function and structure. There are about 200 types of cells present in the human body. The cells work in harmony to perform basic functions necessary for humans to survive. According to scientists, the number of bacterial cells exceeds the number of human cells. Some of the types of cells are given below:

Stem Cells

The stem cells originate as unspecialized cells and develop into specialized cells to build specific organs and tissues. The cells can divide many times to replenish and repair tissue. The scientists take advantage of the renewal properties of these structures.

Bone Cells

They are the connective tissue present in the skeletal system. The bone cells are made up of a matrix of collagen and calcium phosphate minerals. The types of bone cells are Osteoclasts, osteoblasts, and osteocytes.

Blood Cells

Bone marrow is produced by the blood cells. The types of blood cells are Red Blood Cell, White Blood Cell, and platelets. The blood cells determine the blood type and are responsible for transporting oxygen.

Muscle Cells

Forms muscle tissue to enable body movements. The types of muscle cells are skeletal, cardiac, and smooth.

Fat Cells

The fat cell is a major component of the adipose tissue. When fat is stored, the cells become round and swollen. It shrinks when the fat is used. Adipose has a critical endocrine function, which produces hormones that influence sex hormones.

Skin Cells

The skin cell is composed of epithelial tissue supported by connected tissue called dermis. The outermost layer is a flat and closely packed cell. They protect the internal structure of the body from damage and acts as a barrier against germs.

Nerve Cells

The basic unit of the nervous system is nerve cells. Nerves send signals to other body organs via nerve impulses. The central cell contains neurons, cytoplasm, and organelles.

Endothelial Cells

It makes the inner lining of blood vessels and body organs like brain, heart, etc. The endothelial cells are responsible for the creation of new blood cells.

Sex Cells

Sex cells are reproductive cells produced in male and female gonads that bring new life into existence. The male sex cells have a long tail-like projection called flagella. Female sex cells are relatively larger than the male sex cells.

Pancreatic Cells

Pancreatic cells regulate blood glucose concentration levels for the digesting of proteins, fats, etc. the pancreas function as both endocrine and exocrine organ. It means that it discharges hormones both through ducts and to organs directly.

Cancer Cells

Cancer cells work to destroy the body. It results from the development of abnormal cell properties that cause cells to spread to other locations.
