What is the name of the organ that synthesizes vitamin D?

In the presence of sunlight, a form of vitamin D3 called cholecalciferol is synthesized from a derivative of the steroid cholesterol in the skin. The liver converts cholecalciferol to calcidiol, which is then converted to calcitriol (the active chemical form of the vitamin) in the kidneys.

Which part of the body system controls fluid loss protects deep tissues and synthesizes vitamin D?

Which body system protects underlying organs regulates body temperature and helps make vitamin D?

The integumentary system is the largest of the body’s organ systems, made up of the skin and its associated appendages. The integumentary system distinguishes, separates, and protects the organism from its surroundings, but also plays a key metabolic function, as the major region for vitamin D production.

Which body system protects and covers the body?

The skeletal system provides the shape and form for our bodies in addition to supporting and protecting our bodies, allowing bodily movement, producing blood cells, and storing minerals. This system consists of bones, cartilage, and joints.

How does the body synthesizes vitamin D?

Vitamin D3 (cholecalciferol) is synthesized in the skin by the reaction of 7-dehydrocholesterol with UVB radiation, present in sunlight with an UV index of three or more.

Is vitamin D synthesized in the body?

A unique aspect of vitamin D as a nutrient is that it can be synthesized by the human body through the action of sunlight. These dual sources of vitamin D make it challenging to develop dietary reference intake values. Vitamin D, also known as calciferol, comprises a group of fat-soluble seco-sterols.

What synthesizes vitamin D and prevents water loss?

The skin plays important roles in protection, sensing stimuli, thermoregulation, and vitamin D synthesis. It is the first layer of defense to prevent dehydration, infection, and injury to the rest of the body. Sweat glands in the skin allow the skin surface to cool when the body gets overheated.
