The regulation of human life activities must pay attention to correct methods and forms, and the regulation includes hormone regulation, fluid regulation, neural regulation, etc., as well as internal environment, water and salt regulation and other forms of regulation. Paying attention to regulation is more conducive to health. 1. Plant regulation is mainly based on hormone regulation. Plant hormones are synthesized in the plant body and transported to the site of action, which have a significant effect on the life activities of the plant body. The main growth hormones such as auxin: promote plant growth; promote rooting of cuttings; promote fruit development; prevent falling flowers and fruits; low concentrations promote plant growth, high concentrations inhibit plant growth, and even cause plant death. Used for weed control. 2. The body fluid regulation of humans and higher animals includes hormone regulation and chemical regulation (CO2). For example, the pituitary gland secretes growth hormone, which controls human growth and development. Insufficient secretion of growth hormone in childhood can cause dwarfism, while excessive secretion can cause gigantism. Excessive secretion of growth hormone in adults can cause acromegaly. The thyroid gland secretes thyroid hormone, which can promote metabolism in the body and increase the excitability of the nervous system. Insufficient secretion of the thyroid gland in childhood can cause cretinism. Insufficient secretion of the thyroid gland in adults can cause endemic goiter. Excessive secretion of the thyroid gland can cause hyperthyroidism. 3. Neuroregulation is the main way to regulate animal life activities. After people perceive environmental stimuli, they will respond quickly. In this reaction process, many organs or tissues need to be involved, such as eyes, nose, ears, skin, nerves, brain, spinal cord and motor organs. This is a continuous process of receiving information → transmitting information → processing information → transmitting information → reacting, and is the result of the coordinated action of many organs. 4. In addition, animal behavior, constant body temperature, stable osmotic pressure, blood sugar balance, immune regulation, etc. are all indispensable conditions for the normal operation of various life activities. |
