• Heart, lungs, and kidneys

• Skin, hair, and nails

• Bones, muscles, and joints

• Stomach, liver, and intestines

What is the primary function of the integumentary system?

• Circulation

• Respiration

• Protection

• Digestion

How does the skin contribute to thermoregulation?

• By facilitating muscle contraction

• By producing digestive enzymes

• By synthesizing proteins

• By sweating and vasodilation

Where does mitosis occur within the epidermis?

• Stratum corneum

• Stratum basale

• Stratum granulosum

• Stratum lucidum

What is the role of melanin in the skin?

• To regulate body temperature

• To aid in digestion

• To protect against UV radiation

• To produce vitamin D

What causes the different colors in skin?

• The amount of keratin

• The thickness of the epidermis

• The quantity of melanin

• The number of sweat glands

What is the significance of the stratum basale?

• It is responsible for skin color

• It is the outermost layer of the skin

• It is where hair growth begins

Which layer of the skin contains sweat glands?

What is the function of the hypodermis?

• To store fat and provide insulation
