Integumentary System Basics

Front

What is the primary function of the integumentary system?

Back

The primary function of the integumentary system is to protect the body from external damage, regulate temperature, and provide sensory information.

Front

What are the main layers of the skin?

Back

The main layers of the skin are the epidermis, dermis, and hypodermis (subcutaneous layer).

Front

What is homeostasis in relation to the skin?

Back

Homeostasis in relation to the skin refers to the skin's ability to maintain a stable internal environment, including temperature regulation and moisture balance.

Front

What is the role of sweat glands in thermoregulation?

Back

Sweat glands help cool the body by producing sweat, which evaporates from the skin surface, removing heat.

Front

What is the Stratum Corneum?

Back

The Stratum Corneum is the outermost layer of the epidermis, consisting of dead, flattened skin cells that provide a barrier to protect underlying layers.

Front

How do blood vessels in the skin respond to heat?

Back

Blood vessels in the skin dilate (widen) to increase blood flow, allowing heat to dissipate and cool the body.

Front

What is the function of the dermis?

Back

The dermis provides structural support to the skin, contains blood vessels, nerves, hair follicles, and glands.

Front

What is the significance of the vasculated area of the skin?

Back

The vasculated area of the skin, primarily the dermis, is significant for supplying nutrients, regulating temperature, and facilitating healing.

Front

What is the role of keratin in the skin?

Back

Keratin is a protein that provides strength and waterproofing to the skin, particularly in the outer layers.

Front

What happens to the oldest cells of the epidermis?

Back

The oldest cells of the epidermis, found in the Stratum Corneum, eventually shed off as new cells are produced in the lower layers.
