Introduction:
For the regulation of other organs in the body, the endocrine system in response to internal signals secretes various hormones. The hormones are chemical signals secreted by the endocrine glands.

Answer to Problem 1DYKB
Correct answer:
Programmed cell death/destruction of aging cells is not a general process controlled by the endocrine system. Therefore, option d. is correct.
Explanation of Solution
Reason for the correct statement:
Option d. is given as “Programmed cell death/destruction of aged cells”. The endocrine system controls and regulates the growth, development, and
Hence, option d. is correct.
Reasons for incorrect statements:
Option a. is given as “development, growth, and metabolism”
Endocrine system stimulates the secretion of thyroid hormones that are responsible for growth, development of some tissues and organs and also involved in the metabolism of the body. Hence, option a. is incorrect.
Option b. is given as “control of reproductive activities”. Endocrine glands control reproduction by stimulating the secretion of testosterone, progesterone, and estrogen that controls the growth and development of male and female reproductive parts.
Hence, option b. is incorrect.
Option c. is given as “maintenance of homeostasis of blood composition”.
Endocrine controls the homeostasis of blood composition by stimulating parathyroid hormones, insulin, glycogen. Hence, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
Endocrine glands are made up of epithelial tissues, which cause the release and production of hormones.
