Apocrine vs Merocrine Apocrine and merocrine glands are both types of exocrine glands, which secrete products through ducts. The main differences between the two are how they release their secretions, their location, and the composition of their secretions: Release method Apocrine glands release their secretions by pinching off parts of the cell membrane, while merocrine glands release their secretions through exocytosis, which doesn't damage the cell. Location Apocrine glands are found deep within the skin, while merocrine glands are found on the surface of the skin. Secretion composition Apocrine gland secretions are thicker and contain nutrients for skin bacteria, while merocrine gland secretions contain water and sodium chloride. SALTY Thermoregulation Thermoregulation is the process by which an organism maintains its body temperature within a certain range, even when the external temperature is different. It's a key part of homeostasis, which is the state of dynamic stability within an organism's internal conditions. Here are some key points about thermoregulation: How it works The hypothalamus is the body's thermostat, and it regulates temperature homeostasis by balancing heat production and heat loss. The hypothalamus contains temperature sensors that receive information from the body's peripheral and central thermoreceptors. These sensors detect surface temperatures and core temperatures, respectively. –Thermoregulation ▪The main function of sensible perspiration ▪Eccrine sweat glands work with cardiovascular system to regulate body temperature
