검증된 단계별 안내1
Understand the role of the skin in hormone production. The skin is involved in the synthesis of certain hormones, particularly those related to calcium regulation.
Identify the hormone related to calcium regulation. Calcitriol is the active form of vitamin D, which is crucial for calcium homeostasis in the body.
Learn how calcitriol is produced. The skin synthesizes vitamin D3 when exposed to sunlight, specifically UVB radiation. This vitamin D3 is then converted into calcitriol through processes in the liver and kidneys.
Differentiate between the hormones listed. Insulin, adrenaline, and thyroxine are not produced by the skin. Insulin is produced by the pancreas, adrenaline by the adrenal glands, and thyroxine by the thyroid gland.
Conclude that calcitriol is the hormone produced by the skin, as it is involved in the synthesis pathway starting from vitamin D3 production in the skin.
