Roles of the skin

Answer 1

Skin is the largest organ that a person has, it covers a 20.83 sq ft on a adult sized body. there are three main layers of tissue that make up skin; they're the epidermis, the dermis, and also the subcutaneous fascia, which is also known as the hypodermis. Skin, acts a regulator for your body temperature which contributes to your overall homeostasis. the reason why you sweat and get goose bumps is because it's your body's attempt to return to homeostasis. the body changes the size in your blood vessels in your skin. as your temperature rises your blood vessels in your skin get larger, this is called vasodilation. this is when you sweat because it is your body's attempt to push as much hot blood as possible to a cooler surrounding area. the reverse of that is called vasoconstrict, this is when your blood vessels become smaller in diameter. the body forces blood away from the skin and back to the core where it is warmest; causing goose bumps. the sweat and sebaceous glands, located in the dermis have a part in maintaining a steady body temperature. there are two main types of sweat glands. the apocrine and the eccrine; the eccrine glands are important to the regulation of body temperature. sweat glands can be activated by heat, pain, fever, or nervousness. The innermost layer of skin which is known as the subcutaneous fascia is responsible for housing lipocytes, lipocytes produce the fat needed to not only provide padding , but also acts a insulation system for temperature regulation.
