16. Which of the following statements is true of the adrenal glands?
A. They're located in the neck.
B. They're ductless glands.
C. They help regulate the pituitary gland.
D. They secrete prolactin.

Respuesta :

(b) they are ductless glands. The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol, found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla.

Answer:

B. They're ductless glands.

Explanation:

The adrenals are glands located one over each kidney, they have no ducts, but distinct secretory tissues, the outer part being the cortex, while the inner part is the medulla.

Adrenal glands are responsible for producing various hormones, such as adrenaline (a hormone that prepares the body to perform physical activities and physical efforts) and noradrenaline (whose main function is to keep blood pressure at normal levels). Both are produced in the adrenal medulla from biochemical modifications of tyrosine.

In addition, they also secrete aldosterone, the hormone responsible for salt resorption by the kidneys, and cortisol, which helps control stress and decrease inflammation.
