Hair is primarily made of a protein called keratin, which is produced by hair follicles in the skin. The main part of hair that we see is made up of dead cells, while the living cells are found at the base of the hair follicle.
Pus is primarily composed of dead white blood cells, debris, tissue fluids, and bacteria. It often has a thick, creamy consistency due to the mixture of these components.
Dandruff is primarily caused by the shedding of dead skin cells from the scalp. These dead skin cells are shed from the outermost layer of the epidermis, known as the stratum corneum.
Yes, the epidermis is made up of multiple layers of cells, with the outermost layers primarily consisting of dead skin cells. These outer layers provide a protective barrier for the body, while the deeper layers contain living cells responsible for skin regeneration and repair.
Yes, hair is primarily composed of a protein called keratin, which is produced by hair follicles in the skin. While hair itself is not alive, it is formed from living cells in the hair follicles.
The structure involved in the breakdown of red blood cells are called macrophages. Macrophages are white blood cells that are in connective tissues. They are formed to accumulate damaged or dead cells.

Dust is primarily made up of dead cells.
The process of recycling dead cells is carried out by specialized cells called phagocytes. These cells engulf and break down the dead cells, recycling their components into new molecules that can be used by the body for energy or building new cells.

Dead cells are found in the outermost layer of the skin, known as the stratum corneum. This layer is composed of flattened, fully keratinized dead skin cells that provide a protective barrier for the skin. Exfoliation helps to remove these dead cells and reveal healthy, radiant skin underneath.
Dandruff is primarily caused by the shedding of dead skin cells from the scalp. These dead skin cells are shed from the outermost layer of the epidermis, known as the stratum corneum.
Skin is primarily composed of living cells, but the outermost layer, known as the stratum corneum, consists of dead skin cells. These dead cells are essential for protective functions, forming a barrier against environmental damage and pathogens. Underneath this layer, living cells continuously regenerate, pushing older cells up to the surface where they eventually die and are shed. Thus, while the outermost layer is made of dead cells, the skin as a whole contains both living and dead cells.

Fecal matter primarily consists of water (about 75%), which helps in its consistency. The solid components include undigested food particles, bacteria (both live and dead), cells shed from the lining of the intestines, and various waste products from metabolism. Additionally, it contains salts, fats, and fiber. These components play a crucial role in the digestive process and overall gut health.
Most of the cleanup of dead red blood cells takes place in the spleen. The spleen contains specialized cells called macrophages that engulf and break down the old red blood cells, recycling their components for future use in the body.
Cells in the lower layers of the epidermis divide continually, producing new cells that constantly push through the layers of the epidermis. By the time those cells reach the outer layer of the epidermis, they are dead and ready to slough off.
