The Integumentary System

The integumentary system involves skin, nails, nerves, hair, and glands. The main act of the integumentary system is to protect the body from the atmosphere. It works to protect from illnesses, body temperature and body moisture. In sequence for this to happen, the integumentary system works together with all different systems in our body. Functions of integumentary system protects, secrets, maintains body temperature, absorbs, and receives stimuli. The integumentary system is the organ system that secures the body from any damage or loss of water. The integumentary system protects us and has many functions. Secures the body's tissues and organs.
Our body communicates from parts to other parts in the body to help function and take care of us. Our systems maintain to help function us properly. One of our defenses to protect our immune system is the skin. We have very small glands in the skin which produce oils that work the skin. In the skin we have live immune cells which prevents infections. Vitamin D is how we get calcium, calcium and digestive system work together. Are skin works with our body temperatures. When we are very hot or very cold our brain send nerve impulses to our skin. When the hair on our skin is facing upward it's easier for the body to get more warmth then if the hairs are lying down. The glands below our skin create sweat and that helps us evaporate the coldness or heat. If we are too cold we will become warm but if we are too hot then we will cool off. Our skin plays a big role for our body. Our nervous system reacts from touch. Example, when your foot step on a toy, the foot's nerve cells send signals up leg then the spinal cord, and up to the brain. The brain
Epidermis has 5 layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. The germinativum and spinosum undergo continual cell division and produce all the layers. As cells moves toward the surface, they become flatter, increasingly full of keratin and finally die. Sebaceous glands are oil glands found all over the skin. Usually empty into hair follicles. Absent in the palms and soles. Produces sebum moisten and is waterproof. Infected glands produce acne. Sudoriferous glands is sweat helps inhibit the growth of bacteria. Important in maintaining body temperature. Hair follicles produce hairs. Epidermal growths that function in protection. Consists of a shaft above the surface, and root that penetrates the dermis. As daughter cells are pushed further from the growing region at the base of the follicle they harden and die. Most of hair shaft is dead material and almost entirely protein. Come in a variety of sizes and shapes. Nails like modification of the epidermis. Contains a free edge, a
