Informative Speech On Integumentary System

Today I am going to be writing to you about the Integumentary system. Integumentary system is the organ system that protects the body from damage. The system includes skin, nails, skin derivatives hair and glands. The integument is the largest system of the body. It includes 16% of our body weight. It is made up of two parts cutaneous membrane and accessory structures. The accessory structures include hair, nails and exocrine glands. Cutaneous membrane is the epidermis and papillary layer of the dermis. The papillary layer is the uppermost layer of the skin. The job of a integumentary system is to protect. The skin provides a protective barrier from the external environment and prevents dehydration by storing water and fat. It acts as a food source protecting our body from the effects of starvation. …show more content…
Epidermis is the outer layer of the skin and is the first line of defense. It contains layers of cells that contain the protein keratin. It has five to six layers. The outer of our skin is waterproof that’s why we don’t absorb water when we take baths. When the skin is healthy it is difficult for viruses and bacteria to enter. Cells of the epidermis have the ability to grow back. When we get a cut or a bruise the skin heals and replaces damaged skin with ease. We lose skin cells on a regular basis. Our skin forms a new outer layer about every 35 days. Large amount of dust is our dead skin cells. The epidermis and dermis make up the integument. Epidermal has five sublayers Stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum and stratum basale. Stratum corneum is the top layer of dead flat cells. Stratum lucidum is the thin layer of dead cells that we can 't see. Stratum granulosum become flat when the move to the epidermis surface. Stratum spinosum gets closer to stratum granulosum. Last, but not least is the stratum basale it consists of basal cells that make new cells for the
