The integumentary system is a system of organs that excretes, stores fat and helps in temperature regulation. It is made up of the skin, hair, nails, the subcutaneous tissue below the skin and includes dermatology as well. The integumentary system is also known as the cutaneous membrane and it is the largest organ in the body. In this article we will explore further into what exactly the integumentary system is and how it works.
The main functions of the skin are to act as a barrier from things from entering or leaving our bodies. The skin protects us from microbes, ultraviolet radiation and chemicals. Other functions of our skin include helping to regulate body temperature by sweating, storing nutrients such as vitamins A, D, E and K as well as acting as a sense organ for touch.
There are three different types of skin layers:
Epidermis: This layer is only about 0.1mm thick in most areas of our body but can be thicker in areas such as our palms and soles. It consists mostly of keratinocytes which are cells that produce keratin to give our skin strength and elasticity. The epidermis also contains melanocytes which produce melanin and protects us against UV radiation damage while giving us pig
The integumentary system is the organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside. The system comprises the skin and its appendages (including hair, scales, feathers, hooves, and nails).
The integumentary system has a variety of functions; it may be protective (barrier against injury and harmful chemicals), but also plays important roles in temperature regulation, sensation, synthesis of certain vitamins and skin pigmentation. In most terrestrial vertebrates with significant exposure to sunlight, the integumentary system also provides for vitamin D synthesis.
The skin is the largest organ in the body. For the average adult human, the skin has a surface area of between 1.5-2.0 square metres (16.1-21.5 sq ft), most of it is between 2–3 mm (0.079–0.118 in) thick. The average square inch (6.5 cm²) of skin holds 650 sweat glands, 20 blood vessels, 60,000 melanocytes, and more than 1,000 nerve endings.
The epidermis is composed of multiple layers of flattened cells that overlie a base layer (stratum basale) composed of columnar cells
The integumentary system is the largest and most visible organ in the human body. It is composed of cells, tissues and organs that protect the human body from various kinds of dangers, help maintain homeostasis, receive and interpret stimuli, and regulate body temperature.
The integumentary system is the body system that consists of the skin, hair, nails, and associated muscles and glands. The biggest organ in the body is the skin, which accounts for about 15% of a person’s total body weight.
The skin has three main functions: protection, regulation, and sensation. Protection against trauma and infection is the primary function of the skin. The skin provides a waterproof barrier that prevents pathogens from entering our bodies. It also acts as a barrier from ultraviolet radiation from sunlight. The epidermis has cells called melanocytes that produce melanin, which gives our skin its color and protects it from UV rays. The dermis produces an oily substance called sebum, which makes our skin waterproof by covering it in oil.
Regulation refers to the ability of the skin to regulate temperature by sweating or shivering. Sweating cools us down when we are too hot and shivering warms us up when we are too cold. Sensation refers to our ability to feel sensations such as pain, touch, pressure, temperature, and vibration through receptors in our skin called nerve endings.
The skin is the largest organ in the human body. It protects the body from injury, regulates body temperature and produces Vitamin D. The integumentary system consists of the skin, hair, nails and exocrine glands.
The skin has three layers: the epidermis, dermis and subcutaneous tissue (hypodermis). The epidermis is the outermost layer of the skin. It provides a waterproof barrier and creates our skin tone. The dermis lies below the epidermis and contains tough connective tissue, sweat glands, hair follicles and blood vessels. The deepest layer of skin is called subcutaneous tissue or fat layer. This layer of fat insulates the body and gives it energy for metabolism.
The integumentary system is made up of the skin, hair, nails, and related muscles and glands. The skin is only a few millimeters thick but 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. Its primary function is to act as a protective covering for the body. The other functions of the skin include maintaining body temperature, storing water and fat, synthesizing vitamin D, excreting waste products (such as urea), and receiving sensory information about pressure, pain, vibration, temperature, and body position.
