The process by which the body maintains stable internal conditions such as temperature, blood pressure, and pH, despite changes in the external environment.

The body’s ability to keep its internal environment relatively constant, allowing cells and organs to function properly.

A process that helps maintain homeostasis by reversing a change to return the body to normal conditions. Example: sweating to cool the body when it gets too hot.

A response that strengthens or increases the original stimulus instead of reversing it. Example: contractions during childbirth.

Large molecules made by living organisms that are essential for life, including carbohydrates, lipids, proteins, and nucleic acids.

Organic molecules that provide quick energy for the body; examples include sugars and starches.

Fat molecules that store long-term energy, make up cell membranes, and help protect organs.

Molecules made of amino acids that perform many functions in the body, such as building tissues, enzymes, and hormones.

A group of similar cells that work together to perform a specific function in the body.

Groups of organs that work together to maintain homeostasis and support life functions, such as the circulatory, respiratory, and nervous systems.

Term	Definition
Homeostasis	The process by which the body maintains stable internal conditions such as temperature, blood pressure, and pH, despite changes in the external environment.
Internal Stability	The body’s ability to keep its internal environment relatively constant, allowing cells and organs to function properly.
Negative Feedback	A process that helps maintain homeostasis by reversing a change to return the body to normal conditions. Example: sweating to cool the body when it gets too hot.
Positive Feedback	A response that strengthens or increases the original stimulus instead of reversing it. Example: contractions during childbirth.
Biomolecules	Large molecules made by living organisms that are essential for life, including carbohydrates, lipids, proteins, and nucleic acids.
Carbohydrates	Organic molecules that provide quick energy for the body; examples include sugars and starches.
Lipids	Fat molecules that store long-term energy, make up cell membranes, and help protect organs.
Proteins	Molecules made of amino acids that perform many functions in the body, such as building tissues, enzymes, and hormones.
Tissue	A group of similar cells that work together to perform a specific function in the body.
Organ Systems	Groups of organs that work together to maintain homeostasis and support life functions, such as the circulatory, respiratory, and nervous systems.
