Types of cells that compose the human body.
What types of cells is the body made from?
Has direct major significance to obesity but very hard to measure.
There are hundreds of different cell types in the human body, but here are 20 of the most common types. Please note that providing exact percentages by weight for each cell type is difficult, as the abundance of specific cell types varies depending on factors such as location, age, and overall health:
Red blood cells (erythrocytes) - transport oxygen and carbon dioxide throughout the body
White blood cells (leukocytes) - protect the body from infections and foreign substances
Lymphocytes (T cells, B cells, and natural killer cells)
BasophilsPlatelets (thrombocytes) - aid in blood clotting
Epithelial cells - form the lining of body surfaces and cavities
Endothelial cells - line the interior surface of blood vessels and lymphatic vessels
Smooth muscle cells - found in the walls of internal organs and structures, such as blood vessels and the digestive tract
Skeletal muscle cells (muscle fibers) - responsible for voluntary movement
Cardiac muscle cells (cardiomyocytes) - make up the heart muscle
Adipocytes (fat cells)
- store energy in the form of fat and insulate the bodyNerve cells (neurons)
- transmit electrical signals and form the basis of the nervous system
Glial cells - support and protect neurons in the nervous system
c. MicrogliaFibroblasts - produce the extracellular matrix and collagen, playing a key role in wound healing
Chondrocytes - maintain and produce cartilage
Osteocytes - maintain and regulate bone tissue
Osteoblasts - form new bone tissueOsteoclasts - break down bone tissue
Spermatocytes - precursor cells that develop into sperm cells
Oocytes - female germ cells that develop into eggs
Pancreatic cells - involved in the production of digestive enzymes and hormones (e.g., insulin, glucagon)
Hepatocytes - the main functional cells of the liver, involved in metabolism, detoxification, and bile production
This list provides an overview of some of the most common cell types in the human body, but it's important to note that there are many more specialized cell types with unique functions.
