Endocrine and Exocrine Glands
690 Questions
The endocrine and exocrine glands topic explores the human body's essential secreting structures, including the pituitary, thyroid, and salivary glands. Questions often focus on gland locations, their specific secretions, and crucial physiological functions. This subject is a core component of the general science syllabus across many highly competitive examinations.

Endocrine and Exocrine Glands Questions
-
pitutary
-
liver
-
pancreas
-
salivary
A
Correct answer
Explanation
The pituitary gland is called the 'master gland' because it secretes hormones that regulate other endocrine glands, including the thyroid, adrenal glands, and reproductive glands. The liver produces bile and metabolizes nutrients, the pancreas produces digestive enzymes and insulin, and salivary glands produce saliva.

Thyroid
-
Pancreas
-
Pituitary
-
Parathyroid
B
Correct answer
Explanation
The pancreas is correctly described as pistol-shaped in anatomical literature. Its head resembles the handle of a pistol, while its body and tail correspond to the barrel and muzzle. The thyroid is butterfly-shaped, the pituitary is pea-sized, and the parathyroids are tiny rice-grain sized glands.

Lungs
-
Hormone
-
Salivary gland
-
Sweat gland
B
Correct answer
Explanation
Ductless glands (endocrine glands) secrete hormones directly into the bloodstream. Hormones are chemical messengers that regulate body functions. 'Lungs' are respiratory organs. 'Salivary gland' and 'Sweat gland' are exocrine glands with ducts, not ductless.

-
Endocrinologist
D
Correct answer
Explanation
Endocrinologists specialize in treating thyroid problems and other ductless (endocrine) glands that produce hormones. Urologists treat urinary issues, Oncologists treat cancer, and Podiatrists treat foot disorders. The thyroid is a key endocrine gland.

None of these
B
Correct answer
Explanation
The liver is the largest gland in the human body, weighing about 1.5 kg in adults. It performs over 500 functions including detoxification, protein synthesis, and bile production. The thyroid and pancreas are much smaller endocrine glands. The liver is both a gland and the largest internal organ.
-
Lachrymal
-
Pituitary
-
Thyroid
-
Pancreas
A
Correct answer
Explanation
The lacrimal glands (also spelled lachrymal) are the tear-producing glands located above each eye. They secrete the watery layer of tears that lubricates and protects the eyes. The pituitary is the 'master gland', thyroid regulates metabolism, and pancreas produces digestive enzymes and hormones like insulin.
-
Pancreas
-
Thyroid
-
Pituitary
-
Spleen
C
Correct answer
Explanation
The pituitary gland is called the 'master gland' because it produces hormones that control other endocrine glands like thyroid, adrenal glands, and reproductive glands. It's located at the base of the brain and regulates growth, metabolism, reproduction, and stress response. The pancreas regulates blood sugar, thyroid controls metabolism, and spleen is part of immune system.

-
Pancreas
A
Correct answer
Explanation
Lachrymal glands, located above each eye, produce tears that lubricate and protect the eyes. Tears contain water, salts, and antibodies to keep eyes moist and clean.

Liver
-
Pancreas
-
None of these
B
Correct answer
Explanation
The liver is the largest gland in the human body, weighing around 1.5 kg. It performs vital functions including detoxification, bile production, and nutrient metabolism.

-
Spleen
C
Correct answer
Explanation
The pituitary gland is called the master gland because it produces hormones that regulate other endocrine glands. It controls growth, metabolism, and reproduction.

Pituitary
-
Infundibulum
B
Correct answer
Explanation
The liver is the largest gland in the human body (weighing about 1.5 kg) and also the largest internal organ. It performs over 500 functions including detoxification, protein synthesis, and bile production. Pancreas is a gland but much smaller.
-
Thyroid
-
Adrenal
-
Thymus
-
Pituitary
B
Correct answer
Explanation
The adrenal glands sit atop each kidney like a cap. They produce hormones like cortisol and adrenaline. The name literally means 'near the kidney'. Other options are endocrine glands but not positioned above kidneys.
C
Correct answer
Explanation
The liver is the largest gland in the human body and also the largest internal organ. It weighs about 1.5 kg and performs over 500 functions including detoxification, protein synthesis, and bile production. The kidney is an organ, not primarily a gland. 'Viens' appears to be a misspelling of 'veins'.
-
thyroid
-
pituitary
-
liver
-
kidney
C
Correct answer
Explanation
The liver is the body's largest internal gland (1.4-1.6 kg), performing vital functions: bile production, detoxification, protein synthesis, glycogen storage. The thyroid and pituitary are much smaller endocrine glands. Kidneys filter blood but are excretory organs, not glands.

A
Correct answer
Explanation
The liver is the largest internal organ and largest gland in the human body, weighing approximately 1.4-1.6 kg in adults. It performs vital functions including detoxification, protein synthesis, and bile production. The brain, while heavy, is not classified as a gland. Kidneys, eyes, and stomach are smaller than the liver.
