Integumentary System (DHO part 1)

The skin is a/an ​ (a)   because it serves as a covering; a/an ​ ​ (b)   because it consists of different types of tissues that work together; and a/an ​ (c)   because it has multiple organs that work together for a particular function.

• membrane
• organ
• system
• organism
• cell
• tissue

The skin performs many functions including: ​ (a)   against injury, sun damage, and infection; ​ (b)   by dissipating or retaining heat through capillary dilation or constriction; and ​ (c)   as urea and uric acid are released with sweat.

• protection
• temperature regulation
• waste elimination
• water barrier
• sensory perception
• vitamin production
• storage
• absorption

The skin performs many functions including: ​ ​ (a)   due to the presence of merkel cells; ​ (b)   for fat, glucose, and water; and it serves as a ​ (c)   to prevent evaporation.

• sensory perception
• storage
• water barrier
• vitamin production
• absorption
• protection
• temperature regulation
• waste elimination

• sensory perception
• storage
• water barrier
• vitamin production
• absorption
• protection
• temperature regulation
• waste elimination

The skin performs many functions including: ​ ​ ​ (a)   which makes transdermal medications possible and ​ (b)   which is activated by the sun.

• absorption
• vitamin production
• protection
• temperature regulation
• waste elimination
• storage
• water barrier
• sensory perception

When the skin is working to regulate temperature, blood vessels ​ (a)   to release excess heat and ​ (b)   to retain heat.

• dilate
• constrict

In addition to dilating and constricting blood vessels, the skin also regulates temperature through evaporation of perspiration by the ​ (a)   glands.

• sudoriferous
• sebaceous

Match the following

• primary type of cells of the epidermis; adds strength and protection.

• Merkel Cells

• fight infections

• Keratinocytes

• touch receptors

• Dendritic Cells (langerhans cells)

The dermis, which is also called the ​ (a)   or "true skin", has a ​ (b)   layer which forms the fingerprints and a ​ (c)   layer which contains the blood vessels, nerves, hair follicles, and sweat and oil glands.

• corium
• papillary
• reticular

Match the following

• inner layer which is mostly fat and anchors the skin to the body

• dermis

• middle layer which holds the blood vessels, nerves, lymph, sweat and oil glands

• epidermis

• outer layer which has 5 layers of its own

• hypodermis
