Respuesta :

  • Hormones are chemical messengers secreted by glands.

In order to reach different organs and tissues throughout the body, endocrine glands release hormones (chemical messengers) into the bloodstream.

  • Endocrine glands secrete hormones directly into the bloodstream.

Hormones are directly released into the bloodstream by endocrine glands.

  • The pituitary gland plays an important role in puberty and growth.

The pituitary gland regulates a variety of essential bodily processes and functions, including metabolism, growth, sexual development, reproduction, blood pressure, and many others.

  • Epinephrine, triggering the "fight or flight" response, is produced by the adrenal glands, which sit on top of the kidneys.

Corticosteroid hormones and epinephrine, which are produced and released by the adrenal glands, keep blood pressure stable and control metabolism.

  • Less

When hormone concentrations are high, the gland will produce less of the hormone.

  • Many cells produce chemicals called steroids, hormone-like substances that impact inflammation and reproduction.

Eicosanoids (such as prostaglandins and thromboxanes), steroids, and phytoestrogens are examples of compounds that can be categorized as hormones (e.g. estrogen and brassinosteroid)

  • The gland that helps regulate growth, body temperature, and the level of calcium in the blood are called the thyroid and parathyroid.

The thyroid and parathyroid glands are situated behind the larynx, in the front of the neck (voice box). The metabolism of the body is significantly influenced by the thyroid. The balance of calcium in the body is controlled in part by the parathyroid glands.
