Laboratory Activity 3:
Skin
1
, Introduction
The integumentary system majorly consists of the skin which is considered to be the first line
of defense of the body. It also includes accessory structures like the hair, nails, and glands.
The structures that compose the integumentary system are the physical features that are
primarily noticed, thus, encounters the external factors the body collides with. It protects the
internal systems from the foreign bodies and also exposes identifiable formations that may
reveal internal diseases or biological and physiological issues that are not easily recognized
(VanPutte et al., 2016, 94).
The major functions of the integumentary system include protection, sensation, vitamin D
production, temperature regulation, and excretion (VanPutte et al., 2016, 94-95). Such
functions define the defensive nature of the skin and the other accessory structures of the
topic system. The different organs (skin, hair, nails, and glands) can also be destructured and
closely examined to view its different compositions that explain how each organ performs
their functions. For instance, the skin is widely known to be composed of several layers with
varying roles.
In the laboratory activity, Skin, the objectives will be to: (1) further identify the organs of the
integumentary system; (2) thoroughly define and describe the major functions of the organs
the comprises the integumentary system; (3) intricately identify the difference between the
epidermis, dermis, and the subcutaneous layer; and (4) identify the layers of the skin, a hair
follicle, an arrector pili muscle, a sebaceous gland, and a sweat gland on a microscope slide
(in this case, a zoomed image from a smartphone's camera feature), diagram, or model.
