Physiological needs cover two main concepts: homeostasis and appetite (Datta 2011). Homeostasis is defined as “the tendency of a system‚ especially the physiological system of higher animals‚ to maintain internal stability‚ owing to the coordinated response of its parts to any situation or stimulus that would tend to

In order to be classified as a cell‚ the object in question must be able to reproduce‚ respond to chemical signals‚ obtain energy‚ maintain homeostasis‚ and undergo evolution. All cells can be divided into two different categories: prokaryotes or eukaryotes. Bacteria and archaea are classified as prokaryotes while animals and plants are eukaryotes.

ages‚ thyroid hormones play a role in protein synthesis and breakdown‚ increase body heat production in times of prolonged cold weather‚ and set basal metabolic rate. Calcitonin is also regulated by the thyroid gland and is involved with calcium homeostasis between the bone and the circulation. The parathyroid glands are two sets of organs associated with the thyroid gland. The chief cells produce parathyroid hormone (PTH) whose main function is to regulate calcium levels in the body.
