Colt1911 [192]

The inner layer, the dermis, consists of a superficial papillary region of loose, areolar connective tissue, connective tissue and a thicker and deeper reticular region of dense irregular connective tissue connective tissue.

<h3>The layers of the skin</h3>

The skin is the largest peripheral organ that covers the outer layers of the body. It is made up of two layers namely:

  • Epidermis: The epidermis is the outer layer and it is made up of stratified squamous epithelium.

  • Dermis: The dermis is the inner layer of skin. it is made up of superficial and deep layers.

The superficial layer is made up of papillary region of loose areolar connective tissue which helps to attach epithelial tissue to other underlying tissues.

While the deep layer is made up of dense irregular connective tissue which provides strength, making the skin resistant to tearing by stretching forces from different directions.

tia_tia [17]

Answer:

C) decreased functional reserve

Explanation:

Ageing is a biological process which leads to the loss of function of the tissue and cells of the organism.

The biological ageing is determined genetically and can be correlated with the chronological ageing. The ageing is also influenced by the environmental factors which could interfere with the physiology, anatomy and morphology of the organisms.

The cell division cycle gets arrested to prevent the proliferation of these damaged cells and to remove the harmful factors from the body. This leads to the loss of function of the cells and tissues.

Thus, Option-C is the correct answer.
