Question

Ductless glands are called
a. Alveolar glands
b. Tubular glands
c. Exocrine glands
d. Endocrine glands

Answer 1

Hint: Hormones secreted directly into the blood rather than the ducts that present the endocrine system of the endocrine glands where the endocrine glands have lack of ducts. And also known by the name ductless gland. Adrenal gland, hypothalamus gland, parathyroid gland, pineal gland, ovaries gland and pituitary gland are the major gland of the endocrine system.

Complete answer:
A structure that generates the hormones in the body known as endocrine glands. But not secrete the hormones indirectly to the bloodstream that’s why known as the name ductless gland. Hormonal systems help to produce the various hormones through the group of endocrine glands. The activities of the body function mainly tended by the endocrine system. Hypothalamus plays the most important role in the endocrine system that’s linked through the nervous system via the pituitary gland.

In the endocrine system group of capillaries present that’s helped to diffuse the hormones into the bloodstream and also referred to the ductless gland. The hormones like GH, prolactin, TSH, ACTH, produced by the endocrine system into the bloodstream. But the abnormal hormone secretion of the endocrine system generated some disease like gigantism, acromegaly, and dwarfism.

Hence, the correct answer is option (D).

Note: Ductless gland is also known by the name endocrine gland. With the help of the endocrine glands secretion of the hormones not through the ducts or tube but also released directly into the blood. Pancreas is the largest endocrine gland present in the human body and helps to produce the hormones like glucose, insulin and sugar present in the blood entering through the cell in the human body.
