2 Parts of the System Made up of skin, hair, and nails. Skin is the major organ of the system. It is made up of 3 layers: Epidermis- Outermost layer; 5 sub-layers, no blood vessels or nerves. Dermis- Elastic connective tissue, contains blood vessels, nerves, involuntary muscle, sweat glands, & hair follicles. Subcutaneous fascia (hypodermis)- Innermost layer; made up of elastic & fibrous connective tissue, fatty tissue, and it connects to underlying muscles.

4 Parts of the Hair Follicle

5 Functions Protection-
Barrier to the suns ultraviolet rays, pathogens & germs. Holds in moisture. Sensory Perception- The nerves help body to respond to pain, pressure, temperature, and touch sensations. Body temperature regulation- Blood vessels help body retain or lose heat. Storage- Tissues are temporary storage for fats, glucose, water, vitamins, and salts.

6 Functions continued… Absorption-
Substances can be absorbed through the skin, called transdermal medication. Excretion- Skin eliminates salt, waste, & excess water Production- Skin helps in the production of Vitamin D using UV rays from the sun.

7 Pigmentation Skin color is determined by pigments in the epidermis.
Melanin, a pigment, is produced in the epidermis by melanocytes. Every person has the same number of melanocytes, racial groups is what determines the amount of melanin produced.

8 Complications of Pigmentation
A person with an absence of pigments is an albino. Erythema is the reddish color of the skin caused by burns or congestion of blood in the vessels. Jaundice is a yellow discoloration of the skin. Indicates bile in the blood.
