Answer:

Why is healthy skin important? Healthy skin is important because it is your first line of defense against bacteria and other pollutants in the environment. Healthy skin is more resilient when faced with external stresses, serves as an important sensory organ and helps to regulate our body temperature.

The outermost layer of skin, called the epidermis, produces a thin barrier layer called the stratum corneum. This layer varies throughout the body in its structure, thickness, composition and functional properties. For example, the skin on your palms and soles is thicker than on your face.

Skin changes such as wrinkling are one of the physical alterations most readily associated with aging. It may surprise you that the outer layer of the skin, the stratum corneum, changes very little as we age. The main changes occur at a deeper level. Collagen, a basic chemical building block of skin and connective tissue, decreases with age.

The ___________ propel debris-laden mucus away from lower respiratory system structures.
Aliun [14]

The cilia propel debris-laden mucus away from lower respiratory system structures.

<h3>What is function of mucous membrane?</h3>
  • Another general defense against possible infections is provided by the mucous membranes that line the digestive, urinary, and respiratory tracts, as well as the nose, mouth, and lungs.
  • In order to cover and protect the more delicate cell layers underneath it and to trap waste and particle matter, including microorganisms, mucous membranes are made up of a layer of epithelial cells connected by tight junctions.
  • Because they feature ciliated appendages, which resemble hairs, the epithelial cells lining the upper portions of the respiratory tract are known as ciliated epithelial cells.
  • Mucus that contains debris is forced out and away from the lungs by the cilia's movement. The mucus is then coughed up, sneezed out, or swallowed and destroyed in the stomach. The mucociliary escalator is another name for this route of elimination.

What cause's cell division
