Biology Quiz on Human Body

In which part of the body is the thyroid gland located?

• Chest

• Head

• Throat

• Abdomen

Answer explanation

The thyroid gland is located in the throat, specifically in front of the trachea and below the larynx. This makes 'throat' the correct answer, as it is not found in the chest, head, or abdomen.

What disease is treated by insulin?

• Cancer

• Tuberculosis (TB)

• Anemia

• Diabetes

Answer explanation

Insulin is a hormone that regulates blood sugar levels, making it essential for treating diabetes. The other options, cancer, tuberculosis, and anemia, are not treated with insulin.

Which of the following chemical substance is secreted by the pancreas?

• Protein

• Insulin

• Vitamin C

• Fatty acid

Answer explanation

Insulin is a hormone secreted by the pancreas that regulates blood sugar levels. The other options, such as protein, vitamin C, and fatty acids, are not secreted by the pancreas.

Where is insulin produced in the human body?

• Liver

• Spleen

• Pancreas

• Bile duct

Answer explanation

Insulin is produced in the pancreas, a gland located behind the stomach. It plays a crucial role in regulating blood sugar levels, making the pancreas the correct answer.

Match the following in the correct order: Hormone Secretory gland (P) Hormones of Colip (Q) Aldosterone (R) Prolactin (S) Melatonin

• P-a, Q-b, R-c, S-d

• P-b, Q-d, R-c, S-a

• P-c, Q-a, R-d, S-b

• P-d, Q-c, R-b, S-a

Answer explanation

The correct matches are: P-c (Hormones of Colip), Q-a (Aldosterone), R-d (Prolactin), S-b (Melatonin). This aligns with the functions and secretory glands of each hormone.

Graves (Exophthalmic Goitre) disease is caused by over-secretion of .............. due to increase in thyroid.

• Thyroid hormone

• Parathormone

• Aldosterone

• Testosterone

Answer explanation

Graves' disease, also known as Exophthalmic Goitre, is caused by the over-secretion of thyroid hormone due to an increase in thyroid activity, leading to symptoms like bulging eyes and hyperthyroidism.

Which of the following hormones is not secreted by the pituitary gland?

• Thyroid stimulating hormone

• Prolactin

• Vasopressin

• Somatostatin

Answer explanation

Somatostatin is not secreted by the pituitary gland; it is produced in the pancreas and hypothalamus. The other hormones listed—thyroid stimulating hormone, prolactin, and vasopressin—are all secreted by the pituitary gland.

Which human organ contains the 'Islets of Langerhans'?

• Brain

• Gall bladder

• Liver

• Pancreas

Answer explanation

The 'Islets of Langerhans' are clusters of cells in the pancreas that produce hormones like insulin. This makes the pancreas the correct answer, as the other options do not contain these structures.

Which among the following is not digestive enzyme?

• Proteus (Protease)

• Amylase

• Lipase

• Superoxide dismutase

Answer explanation

Superoxide dismutase is an enzyme that helps break down superoxide radicals, not a digestive enzyme. In contrast, protease, amylase, and lipase are all digestive enzymes that break down proteins, carbohydrates, and fats, respectively.

Which acid is secreted by certain glandular cells of the stomach lining?

• Hydrochloric

• Ethanoic

• Formic

• Nitric

Answer explanation

The acid secreted by certain glandular cells of the stomach lining is hydrochloric acid. It plays a crucial role in digestion and maintaining the acidic environment of the stomach.
