Question

Explain chemical coordination in humans and give the names and functions of some hormones.

Answer 1

1. In the human body, chemical control occurs through stimulation, where stimulants are produced from endocrine glands, and chemicals are produced near the contact sites of nerve cells.
2. Endocrine glands are separate from the duct, and their secretions mix directly with the blood. The receptors of these glands reach all the parts of the body through blood, which are located at certain places in the body.
3. Endocrine glands work to control and coordinate with the nervous system, and they participate in controlling and coordinating various functions of the body, for which there is cooperation between these two organizations.
4. When various activities begin, stimulants are secreted as per requirement. The amount and timing of secretion of the propellant is always regularly controlled.
5. Pituitary, pituitary gland, adrenal glands, taste buds, some cells, gonads - ovaries, testicles, and thymus glands are all important endocrine glands.
6. Growth stimulant, adrenal gland stimulant, thyroid gland stimulant, prolactin, oxytocin, luteinizing hormone, antitumor stimulant, follicular gland stimulant, these are the stimulants of pituitary gland. Of these, growth promoters are essential for the growth of the body. Prolactin, oxytocin, luteinizing hormone, follicle stimulating hormone, these hormones are especially important for the reproduction of women's body.
7. Estrogen and progesterone, which are produced by the ovaries, are essential for the physical development of women, while testosterone, which is produced by the testicles, is important for men.
8. The cells of the taste buds produce glucagon and insulin and regulate blood sugar levels.
9. The thyroid gland significantly produces thyroxine and calcitonin. Due to thyroxine, the metabolic process in its body remains functioning smoothly.
10. Adrenaline, noradrenaline, and corticosteroids from the adrenal glands constitutively control many body functions. They include controlling behavior in emergency situations and emotional episodes, stimulating transmission of the cardiovascular and circulatory systems, and stimulating metabolic processes. They also keep the balance of Na and K and metabolism under control.
11. This type of chemical control is very slow in maintaining body position and coordination, but the process is necessary over a long period of time.
