Endocrine glands put their secretions directly into

  1. Ducts

  2. Blood

  3. Both

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct because endocrine glands lack ducts. Hence they are also called ductless glands.
  • The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus, and adrenal glands.
  • Hence endocrine glands put their secretions directly into the blood.
  • So, the correct answer is 'Blood'.

Hormones are produced by

  1. Exocrine glands

  2. Endocrine glands

  3. Holocrine glands

  4. Apocrine glands
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A. Exocrine glands are the glands that secrete their products through ducts.
B. Endocrine glands are the ductless glands which secrete their products directly into the blood.
C. Holocrine glands secrete their products in the cytoplasm which are released due to rupture of cell membrane.
D. Apocrine glands are generally present in the skin and secrete their products on the skin surface.
Hormones are produced by endocrine glands. They are secreted in the blood stream from which they are carried to their target organs.
So, the correct answer is 'Endocrine glands'.

How many of them are secreted by exocrine glands?

  1. Twelve

  2. Three

  3. Eight

  4. Nine
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
 Endocrine glands Thymosin is secreted by the thymus gland.Cortisol is secreted by the adrenal gland.Androgen is secreted by the adrenal gland.Renin is secreted by the kidney.
 Exocrine glands Saliva is secreted by the salivary gland.Pancreatic juice is secreted by the pancreas.Ear wax is secreted by the ceruminous gland.Tear is secreted by lacrimal gland.Milk is secreted by the mammary gland.Mucus is secreted by nasal mucosa as well as through bronchi and trachea.Oil is secreted by sebaceous gland.Bile is secreted by the liver.
  • HCl is secreted by parietal cells and digestive enzymes are secreted by different digestive organ (stomach and small intestine).
  • So, the correct answer is 'Eight'.

Which of the following gland has both exocrine and endocrine parts?

  1. Thyroid

  2. Pituitary

  3. Adrenal

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The endocrine system is composed of ductless glands. Endocrine glands secrete hormones. Glands that have ducts are called exocrine glands. The secretions of exocrine glands reach their target by travelling through a duct (tube). The mixed gland is a gland that produces endocrine and exocrine secretions. The pancreas is an example of a mixed gland because it secretes hormones in the circulation, like insulin and glucagon, but it also releases an exocrine secretion, the pancreatic juice. Whereas, thyroid, pituitary and adrenal glands are not having both endocrine and exocrine system.

Therefore, the correct answer is option D.
