skin

skin is the largest organ of the body and, depending on the species and age, may represent ________of an animal’s body weight.

12%–24%

Anatomically, the skin consists of the following structures:

epidermis, dermis, appendageal system, subcutaneous muscles and fat

It is the outermost layer of the skin and contains no blood cells.

Epidermis

act as a physical and biological barrier to the external environment, preventing penetration by irritants and allergens. At the same time, it prevents the loss of water and maintains internal homeostasis.

epidermis

- made up of 95% of the cell in the epidermis. - Strengthen epidermis, makes it resistant to mechanical trauma. - Arrange into Strata (layers)

Keratinocytes (cytes-cells)

Epidermis Strata

Stratum Corneum , Stratum Lucidum, Stratum Granulosum, Stratum Spinosum, Stratum Basale

Cows do sweat, but they don’t sweat ‘efficiently’ as they reportedly sweat at only ___ the rate humans do.

10%

They also have the ability to “produce a type of foam or lather their bodies” because their sweat has a natural detergent called ?

latherin

small oil-producing gland present in the skin of mammals. Sebaceous glands are usually attached to hair follicles and release a fatty substance, sebum, into the follicular duct and thence to the surface of the skin.
