(a) Homeostasis
(b) Endocrine system
(a) Homeostasis may be defined as the ability of the individual to regulate its internal conditions by controlling its various physiological processes such as blood pH and body temperature. Homeostasis is required for maintaining the health of the individual if the conditions of the surroundings change. Homeostasis is controlled by the nervous system and the endocrine system.
(b) Endocrine system - All the physical activities and life processes in humans are controlled and regulated by the nervous system along with another regulatory system known as the endocrine system. The endocrine system includes various ductless glands which secrete chemicals and hormones directly into the blood. These hormones are then transported to their target site which is far away from their site of production. The response of the target tissue to the action of hormones require seconds/ minutes or even more time. Some examples of the endocrine system are the pituitary gland, thyroid gland and adrenal gland.
