C Correct answer
Explanation

The endocrine system is composed of several endocrine glands. A ductless gland or endocrine gland secretes its product, i.e., hormones directly into the bloodstream and shows its effects at distinct part of the body. Adrenal gland located above kidneys produces adrenalin.

Mucus, saliva, earwax, oil, milk, digestive enzymes, bile juice, tear, cortisol, androgen, HCL, thymosin, rennin, Pancreatic juice

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'.

A Correct answer
Explanation

Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous.

So, the correct option is ‘Saliva’.

D Correct answer
Explanation
A. Alveolar glands are also known as saccular glands and consist of a sac-like secretory portion.
B. Tubular glands have a straight duct with opening that comprises of clusters of secretory glands.
C. Exocrine glands are the glands that secrete their products through ducts.
D. Endocrine glands are the ductless glands which secrete their products directly into the blood.
So, the correct answer is 'Endocrine glands'.

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.

In which category of gland, secretary cells mature, rupture and becomes the secretary product.

Type Example
$1$ Holocrine gland Sebaceous gland
$2$ Exocrine gland Salivary gland
$3$ Apocrine gland Mammary gland
$4$ Merocrine gland Pancreas
  1. $1$
  2. $2$
  3. $3$
  4. $4$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Holocrine glands are a type of exocrine glands. They basically release their contents by rupturing, resulting in the death of the secretory cells itself and the contents are released into the lumen. For example, sebaceous glands.

So, the correct answer is '1'.

Intercellular communication in multicellular organisms occur through 

  1. Digestive system only

  2. Nervous system only

  3. Both nervous and endocrine system

  4. Respiratory system only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In our body, we have 2 types of control and coordinating systems. One is through neurons, known as the nervous system and another is through hormones known as the endocrine system.

Both these systems are responsible for maintaining the overall regulatory system of the body.
So, option C " Both nervous and endocrine system" is the correct answer.
