1.
____________ glands are there in Endocrine system.
Explanation
The endocrine system consists of several glands that secrete hormones directly into the bloodstream. These hormones regulate various bodily functions and maintain homeostasis. The correct answer is "seven" because there are seven major glands in the endocrine system: the hypothalamus, pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and gonads (ovaries in females and testes in males). Each of these glands plays a crucial role in controlling different aspects of the body's functions and maintaining overall health.
2.
____________ produces insulin.
Explanation
The pancreas produces insulin.
3.
_______________ gland is known as master gland.
Explanation
The pituitary gland is known as the master gland because it plays a crucial role in regulating the functions of other endocrine glands in the body. It produces and releases hormones that control various bodily processes, including growth, metabolism, reproduction, and stress response. The pituitary gland is connected to the hypothalamus and receives signals from it to release or inhibit the production of specific hormones. Its control over other endocrine glands makes it the "master" regulator of the body's hormone system.
4.
The job of insulin is to ________________the blood sugar.
Explanation
Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. It works by facilitating the uptake of glucose from the bloodstream into cells, thereby reducing the concentration of glucose in the blood. This process is known as lowering blood sugar levels.
5.
_________________ regulates metabolism and uses iodine.
Explanation
The thyroid gland is responsible for regulating metabolism and requires iodine to produce thyroid hormones. These hormones play a crucial role in controlling the body's metabolism, energy levels, and growth. The thyroid gland absorbs iodine from the bloodstream and uses it to produce thyroxine (T4) and triiodothyronine (T3), which are essential for maintaining proper metabolic function. Therefore, the correct answer is "Thyroid."
6.
Testes controls the development of sex organs in males.
Correct Answer
A. True
Explanation
The testes produce and release hormones such as testosterone, which are responsible for the development and functioning of male sex organs. These hormones play a crucial role in the development of the reproductive system, including the growth of the penis, scrotum, and prostate gland. Additionally, the testes are responsible for the production of sperm, which is necessary for reproduction. Therefore, it is true that the testes control the development of sex organs in males.
7.
The adrenal gland is found on the top of the kidneys.
Correct Answer
A. True
Explanation
The adrenal gland is indeed found on the top of the kidneys. These small, triangular-shaped glands are situated on the upper part of each kidney and are responsible for producing hormones such as adrenaline, cortisol, and aldosterone. They play a crucial role in regulating various bodily functions, including metabolism, blood pressure, and stress response.
8.
Pituitary gland is located below the voice box.
Correct Answer
B. False
Explanation
The pituitary gland is actually located at the base of the brain, not below the voice box. It is a small, pea-sized gland that plays a crucial role in regulating various bodily functions and secreting hormones. Its position in the brain is important for its communication with the hypothalamus and its control over other endocrine glands in the body.
9.
Ovaries balance the amount of water in the body.
Correct Answer
B. False
Explanation
The statement is false. Ovaries are reproductive organs in females responsible for producing eggs and releasing hormones like estrogen and progesterone. They do not have a direct role in balancing the amount of water in the body. The regulation of water balance is primarily controlled by the kidneys and the hormone vasopressin.
10.
Adrenaline prepares body for fight or flight.
Correct Answer
A. True
Explanation
Adrenaline is a hormone released by the adrenal glands in response to stress or danger. It triggers a series of physiological changes that prepare the body for a fight or flight response. These changes include increased heart rate, heightened senses, and increased blood flow to muscles. Therefore, the statement that adrenaline prepares the body for fight or flight is true.
