What tissue(s) is associated with skin cells?

The tissues that are associated with skin cells are epithelial tissue, connective tissue and subcutaneous cellular tissue.

Explanation:

The skin is the outermost covering that the human body possesses, fulfilling important functions such as protection, relationship with the external environment - through sensitive receptors - and thermoregulation.  Skin is divided into epidermis, dermis and hypodermis.

The external cells of the skin, the epidermis, are epithelial cells that when united form the keratinized flat stratified epithelium, a epitelial tissue.  The second layer of the skin, dermis, is predominantly formed by elastic fibers that associate to form the connective tissue. The innermost layer of the skin is the hypodermis, or subcutaneous cellular tissue, formed mainly by fat cells.

Finally, the skin cells are related to other tissues, such as the vascular and nervous, necessary for the nutrition and sensitivity of the skin

Los pulmones y el sistema respiratorio permiten la entrada del oxígeno del aire en el organismo, así como la expulsión de dióxido de carbono al espirar. La respiración es el término que se utiliza para denominar el intercambio de oxígeno procedente del entorno por el dióxido de carbono que se produce en las células.
