Protects the body from various types of damage, such as a loss of water or abrasion from outside. The most extensive organ system has the skin and accessory structures, including hair, nails, sweat glands, and specialized nerve receptors for stimuli (changes in internal or external environments) such as touch, cold, heat, pain, and pressure. It’s main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.
it includes the salivary glands, sweat glands, and glands within the gastrointestinal tract.
The skin consists of epidermis and dermis. The cells are keratinocytes, melanocytes, merkel cells and langerhans cells.
Dermatologists specialize in treating diseases, disorders, and injuries of the skin, hair and nails. They treat common conditions such as acne and warts; chronic skin conditions such as eczema and psoriasis; and more serious diseases like skin cancer. Also some harmful aspects that can occur in the system include stretch marks when pregnant, blisters on the skin, and burns.
Relationship To Other Body Systems
Skeletal system: The integumentary system protects bones, and makes the vitamin D the bones need which makes them harder.
Muscular system: The integumentary system protects the muscles, it promotes heat which helps in the blood flow throughout the body, and activates the sweat glands.
Nervous system: The integumentary system protects the bodies organs.
Endocrine system: The integumentary system protects organs, converts hormones to a state to where they are active. Androgens are involved in regulation of hair growth.
Cardiovascular system: The integumentary system protects organs and prevents fluid loss throughout this system. This system serves as blood protector; Cardio system transports oxygen and nutrients to skin and removes waste from skin, along with providing substances needed by skin glands for sweating.
Respiratory system: The integumentary system protects respiratory organs, along with connecting oxygen to skin cells and removing CO2 from the blood.
Digestive system: The integumentary system protects organs,and provides vitamin D. The digestive provides needed nutrients to the skin.
Urinary system: The integumentary system excretes salts in sweat. The urinary system activates vitamin D made by skin cells, and disposes nitrogenous wastes of skin metabolism.
Reproductive system: This system has modified sweat glands that produce milk. When someone is pregnant we all know that their stomach has to expand because of the fetus inside of her which can cause a change in skin pigmentation.
