Homeostasis Concept Map

Homeostasis refers to the process by which biological systems maintain stability while adjusting to changing external conditions, ensuring optimal functioning of organisms.

Feedback mechanisms help maintain homeostasis by regulating internal conditions, primarily through negative feedback, which counteracts changes, and positive feedback, which amplifies changes.

The hypothalamus regulates various physiological processes, including temperature, hunger, thirst, and emotional responses, and controls the autonomic and endocrine systems to maintain homeostasis.

Hormones act as chemical messengers that coordinate and regulate physiological processes, such as metabolism, fluid balance, and the stress response, to maintain internal stability.

Circadian rhythms are natural, internal processes that regulate the sleep-wake cycle and other bodily functions, repeating roughly every 24 hours and influenced by external cues like light.

The central nervous system consists of the brain and spinal cord, responsible for processing and transmitting information throughout the body, controlling most bodily functions and responses.

The peripheral nervous system includes all nerves and ganglia outside the brain and spinal cord, connecting the CNS to limbs and organs, and facilitating communication between the brain and the body.

Oxytocin is a hormone involved in social bonding, reproduction, and childbirth, playing a crucial role in uterine contractions during labor and influencing behaviors like trust and empathy.

The three main lines of defense for acid-base homeostasis are chemical buffers, the respiratory component regulating breathing, and the metabolic component involving the kidneys.
