What are the three main functions of the skin?

• Protection, regulation, and sensation

• Transport, support, and protection

• Respiration, circulation, and filtration

• Digestion, absorption, and elimination

How does the skin protect the body from pathogens?

• Acting as a physical barrier, producing antimicrobial substances, and housing immune cells

• By providing a warm environment for pathogens to thrive

• By attracting more pathogens to the body

• By weakening the immune system

Explain the role of the skin in regulating body temperature.

• The skin regulates body temperature through the process of thermoregulation.

• The skin regulates body temperature by producing vitamin D.

• The skin regulates body temperature by controlling blood pressure.

• The skin regulates body temperature by aiding in digestion.

What is the function of sebaceous glands in the skin?

• Produce vitamin C for the skin

• Moisturize and protect the skin

• Regulate body temperature

• Produce sweat to cool the body

How does the skin help in the synthesis of vitamin D?

• The skin absorbs vitamin D from the air

• The skin produces vitamin D when exposed to sunlight.

• Vitamin D is produced in the liver, not the skin

• Vitamin D is only obtained through diet and supplements

Describe the role of the skin in sensation.

• Sensation is solely dependent on the muscles, not the skin

What is the function of melanin in the skin?

• It is responsible for producing vitamin D

• It provides structural support to the skin

• It helps protect the skin from the harmful effects of ultraviolet (UV) radiation.

• It helps in regulating body temperature

Explain how the skin acts as a barrier to UV radiation.

• The skin produces melanin and thickens the outer layer to absorb and dissipate UV radiation.

• The skin secretes UV-blocking oils

• The skin becomes transparent to UV radiation

• The skin absorbs UV radiation and stores it for energy

How does the skin help in maintaining homeostasis?

• Causing dehydration, allowing pathogens to enter, and regulating body temperature

• Regulating body temperature, protecting against pathogens, and preventing water loss

• Promoting water loss, regulating body temperature, and protecting against pathogens

• Preventing water loss, regulating body temperature, and causing skin infections

What role does the skin play in the excretion of waste products?

• Producing more waste products

• Transporting waste products to the liver

• Eliminating waste products through sweat glands

• Storing waste products in the skin
