1. IntroHomeostasis-1

Anatomy

The study of the structure of the body and its parts.

Physiology

The study of the functions and processes of the body and its parts.

Homeostasis

The maintenance of a stable internal environment despite changes in external conditions.

Cells

The smallest functional unit of an organism, forming the basic building blocks of life.

Tissue

A group of similar cells working together to perform a particular function.

Organ

A structure composed of at least two different types of tissues working together to perform specific functions.

Organ System

A group of organs that work together to carry out complex functions.

Metabolism

The total of all chemical reactions that occur within a body, including anabolism and catabolism.

Negative Feedback

A regulatory mechanism that reverses a change in a controlled condition.

Positive Feedback

A regulatory mechanism where a change in a controlled condition results in an even greater change.

Stimulus

Any detectable change in the internal or external environment.

Integrator

The component of a feedback loop that processes information and determines the appropriate response.

Effector

An organ or cell that acts in response to a stimulus.

Response

The outcome or action taken as a result of a stimulus being detected.

Homeostatic Feedback Loop

A process that uses feedback to maintain a system's stability.

Autoregulation

The automatic adjustment of organs or tissues to environmental changes.

Extrinsic Regulation

Regulation of the body's systems by external factors such as the nervous or endocrine systems.

Nutrients

Substances that provide energy and materials for growth and maintenance of the body.

Cellular Respiration

The process of converting glucose and oxygen into energy (ATP) for cellular functions.

Disturbance

A failure to maintain homeostasis that can lead to disease or dysfunction.

Set Point

The ideal normal value of a variable in the body that the body tries to maintain.
