Answer to Question #90654 in Cell Biology for ahmad

Question

Which of the following answer choices is a true statement?

The pituitary gland has multiple functions related to the endocrine system.
Secretory cells of an endocrine gland are embedded in muscle tissue.
An endocrine gland is a cluster of hormone-secreting cells surrounded by a network of capillaries.
Target cells produce hormones that are transported throughout the body by the circulatory system.

Answer 1

The true statement is

An endocrine gland is a cluster of hormone-secreting cells surrounded by a network of capillaries.

Endocrine glands are the glands of the endocrine system that secretes hormone directly into the blood such as pituitary gland, parathyroid gland, ovaries, testes etc.

The anterior pituitary gland is surrounded by a capillary network that extends from the hypothalamus and also the follicles of the thyroid gland produce hormones are released into the surrounding capillary network for transport to the rest of the body with the help of the circulatory system. Each parathyroid gland is covered by connective tissue and contains many secretory cells that are associated with a capillary network. 

So it can be concluded from the above information that the endocrine glands are surrounded by  network capillaries to transport the secreted hormone to the body.
