Hormone System of our Body: Endocrine System
Hormone System of our Body: Endocrine System
Animals including humans have a complicated procedure for the functioning of different types of life processes for example respiration, digestion, reproduction, excretion, etc. On account of the functioning of different organs, they have the sensory system and endocrine system for control and coordination. The Endocrine System is liable for the compound coordination of all organs in systems. Various physiological functions of our bodies are heavily influenced by the endocrine system. It comprises all the glands of our body that releases different chemicals for example hormones and enzymes. Endocrine glands are ductless glands. Hormones assume a fundamental part in executing different functions in the body including growth, repair, and development of the body, in turn, the functioning of these organs supports the sensory system.
Endocrine glands in the animals coordinate with the nervous system,endocrine glands are pituitary gland, the pineal gland, the thyroid, the parathyroid, the thymus, the pancreas, the adrenal gland, and the hypothalamus.
The endocrine system is a hormone system, endocrine systems are found in all mammals, birds, fish, etc. This system of hormones includes all the glands located in different parts of our body.
Hormones are made by the glands and released into the bloodstream or the fluid surrounding cells, the receptors which are found in different parts of our body recognize and respond to the hormones.
Function of the hormones:Hormones are chemical messengers that are released into the bloodstream and act on an organ in another part of the body. Hormones reach to all parts of the body, and only target cells with compatible receptors are equipped to destine a particular function.
The hormone receptors that are produced within the cells, these receptors switch on or switch off specific biological processes in cells, tissues, and organs.
Hormones control or regulate many biological processes, such as Insulin is produced by the pancreas for controlling the body’s sugar level
Hypothalamus: The hypothalamus connects our endocrine system to our nervous systems. The hypothalamus controls the endocrine system . Hyopothelemus maintains the balance of our body for example body temperature, hemostasis(water absorption by the kidney), heart rate, blood pressure, electrolyte balance, appetite, sleep cycles, and production of the substance that affects the release of hormones from the pituitary glands.
Pituitary gland: The pituitary gland receives signals from the hypothalamus which are delivered by the hypothalamus gland. The pituitary gland produces its own hormones, several of which act on other endocrine glands,the pituitary gland regulates the secretion of all body hormones in endocrine system,it is that’s why it is also known as master gland of humane body.
Thyroid gland: The thyroid gland is responsible for the growth and development and maturation of vertebrates and also regulates metabolism.
Adrenal glands: The adrenal gland is located in the brain, it consists of two glands the cortex and medulla. Both glands produce hormones that control stress levels and regulate blood pressure, glucose metabolism, and hemostasis.
Pancreas: The pancreas is located in the lower part of the abdomen and is responsible for producing glucagon and insulin. Both hormones help regulate the concentration of glucose in the blood.
Gonads: Gonads are reproductive glands, in male, it exists as testes and in female as ovaries, the testes and ovaries release androgen, estrogens, and progestins but the released amount is different in male and female. All of these hormones regulate growth, development, and reproductive cycles.
