The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is by far the largest organ in the body. The average person’s skin weighs 10 pounds and has a surface area of almost 20 square feet.
The integumentary system consists of the skin, hair, nails, glands, and nerves.
Likewise, is hair an organ? Hair is an accessory organ of the skin made of columns of tightly packed dead keratinocytes found in most regions of the body. As the follicle produces new hair, the cells in the root push up to the surface until they exit the skin. The hair shaft consists of the part of the hair that is found outside of the skin.
Subsequently, one may also ask, what is the anatomy and physiology of the integumentary system?
The integumentary system consists of the skin, hair, nails, the subcutaneous tissue below the skin,and assorted glands. The most obvious function of the integumentary system is the protection that the skin gives to underlying tissues.
What is your largest organ?
How many systems are in our body?
How do you keep your integumentary system healthy?
To keep it gentle: Limit bath time. Hot water and long showers or baths remove oils from your skin. Avoid strong soaps. Strong soaps and detergents can strip oil from your skin. Shave carefully. To protect and lubricate your skin, apply shaving cream, lotion or gel before shaving. Pat dry. Moisturize dry skin.
How does skin protect the body?
The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
How is skin formed?
Skin is made up of three layers. The outermost is the epidermis. This consists mainly of cells called keratinocytes, made from the tough protein keratin (also the material in hair and nails). Keratinocytes form several layers that constantly grow outwards as the exterior cells die and flake off.
What are the 11 systems in the body?
The 11 organ systems of the body are the integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive. Although each of your 11 organ systems has a unique function, each organ system also depends, directly or indirectly, on all the others.
What is keratin protein?
Keratin (/ˈk?r?t?n/) is one of a family of fibrous structural proteins known as scleroproteins. It is the key structural material making up hair, nails, feathers, horns, claws, hooves, calluses, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress.
What are the two main components of the integumentary system?
The two main components of integumentary system are the skin and the appendages. The skin is the largest organ in the body. It has layers which have different functions of protecting the body: the epidermis, dermis and hypodermis.
What are the 7 functions of the integumentary system?
Terms in this set (7) Protection. Microorganism, dehydration, ultraviolet light, mechanical damage. Sensation. Sense pain, temperature, touch, deep pressure. Allows movement. Allows movement muscles can flex & body can move. Endocrine. Vitamin D production by your skin. Excretion. Immunity. Regulate Temperature.
What are the four functions of integumentary system?
Functions include: Protect the body’s internal living tissues and organs. Protect against invasion by infectious organisms. Protect the body from dehydration. Protect the body against abrupt changes in temperature, maintain homeostasis. Help excrete waste materials through perspiration.
What is the function of hair?
Hairs (or pili; pilus in the singular) are characteristic of mammals. The functions of hair include protection, regulation of body temperature, and facilitation of evaporation of perspiration; hairs also act as sense organs. Hairs develop in the fetus as epidermal downgrowths that invade the underlying dermis.
What is hair made of?
Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft.
What type of tissue is the epidermis?
