Cover Outer (Integument)

The outer covering, also known as the integument, is our skin. This organ is the outermost layer of our body and performs many important functions.

One of the main functions of skin is to protect our body. It prevents external factors such as toxins, ultraviolet rays and bacteria from affecting our body. The skin also helps maintain the body's hydration, protects against heat loss, and is also an important sensory organ that can respond to various types of stimuli such as pressure, temperature, pain, and so on.

The skin consists of three main layers: epidermis, dermis and subcutaneous adipose tissue. The epidermis is the outermost layer of the skin and is made up of a number of different cells, such as keratinocytes, which produce keratin, a protein material that gives the skin its strength. The dermis lies beneath the epidermis and contains many different structures such as sebaceous glands, hair follicles, and blood vessels. Subcutaneous adipose tissue is located under the dermis and serves as a source of energy for the body and also helps retain heat.

The skin also plays an important role in the synthesis of vitamin D. When our skin is exposed to ultraviolet light, it begins to produce vitamin D, which is then used to strengthen bones and teeth.

Even though the skin is our most external organ, it can still be prone to a number of problems such as dryness, itching, various types of rashes, infections and others. Therefore, it is important to take care of your skin and monitor its condition.

In general, the outer integument is an incredibly important organ for our body, which performs many different functions. It protects our body, regulates temperature and is a source of vitamin D, among many other functions, making it essential for our health and well-being.

External cover or Integument is one of the parts of the human body that protects internal organs and provides thermoregulation. It consists of several layers of skin: epidermis, dermis, subcutaneous fat and muscles. Each of these layers performs its own function and helps protect the body from harmful environmental factors.

The epidermis is the topmost layer. It consists of cells that protect the inner layer of the dermis from bacteria and other microorganisms. The epidermis contains protective lipids such as ceramides and ceramides, which help retain moisture and protect the skin from water loss.

The dermis is the next layer. The dermis is made up of connective tissue, collagen and elastin, which provide the skin with firmness and elasticity. Also in the dermis are the sebaceous glands, Padian glands and Meibomian glands. The latter secrete a secretion that creates an oily film on the surface of the skin and protects it from water and dirt.

Subcutaneous fat is the third layer. This layer contains a large amount of fat, which serves as a source of energy for the body and helps retain heat during the cold season. There are very few cells in this layer and they fill the gaps between the fibers of the dermis.

Muscle is the last layer. Muscles help us move and control facial expressions. Muscles also respond to changes in temperature and humidity, allowing us to adapt to environmental changes and regulate our body temperature.

The outer integument plays an important role in protecting the body. Damage to it can lead to infection, allergic reactions, and other problems such as scarring or age spots. Therefore, it is very important to take care of your skin and monitor its health. It is necessary to drink enough water, eat right, and use special creams and lotions for skin care.
