Metabolic Reactions and Body Systems

Vocabulary flashcards created to review key concepts related to metabolic reactions and body systems.

Metabolic Reactions

The chemical processes happening inside the cells of living things that convert food into energy and build and break down molecules.

Body Systems

A group of organs and tissues that work together to perform specific functions essential for keeping the body alive and healthy.

Organs

Parts of the body made up of different tissues working together to perform specific jobs.

Tissue

A group of similar cells that work together to perform a specific function within an organism.

Cells

Tiny, self-contained building blocks that make up all animals.

Structure

Refers to how something is built or organized.

Function

The natural role or job that a part or system plays within a living organism.

Models

Representations or tools used to understand, explain, and predict complex phenomena.

Endoscopy

A medical exploration inside the body using a camera and long tube.

Digestion

The process by which the body breaks down food into smaller, absorbable substances.

Absorption

The process of taking in smaller, simpler substances from digested food.

Mechanical breakdown

The physical breaking down of large chunks of food by teeth.

Chemical breakdown

The breakdown of large food molecules into smaller nutrient molecules with the help of chemicals.

Dialysis tubing

A special tubing that acts as a semi-permeable membrane.

Glucose

A simple sugar that serves as the main fuel source for the body's cells.

Starch

A complex carbohydrate made of many smaller glucose units linked together.

Benedict’s Solution

A blue liquid used to test for the presence of certain sugars like glucose.

Iodine

A liquid used to test for the presence of starch.

Indicator

A substance that changes color to signal the presence or strength of a condition.

Pipette

A laboratory tool used to transport a measured volume of liquid.

Nutrients

Vital substances found in food necessary for growth, health, and proper function.

Fiber

Indigestible plant material that helps clean out intestines.

Complex Carbohydrate

Long chains of sugar molecules that take longer to digest.

Saliva

Watery liquid produced in the mouth, containing enzymes for breaking down food.

Amylase

An enzyme that breaks down complex carbohydrates into monosaccharides.

Enzyme

Specialized proteins that speed up chemical reactions necessary for life.

Fat

An important nutrient for energy storage and cell building.

Protein

Essential molecules acting as building blocks for growth and repair.

Simulation

Acting or pretending to be in a real-life situation to learn or practice skills.

Villi

Tiny bumps in the small intestine that help absorb nutrients.

Nutrition Label

A sticker on packaged foods providing information about nutrients and energy.

Bromothymol blue

A chemical pH indicator that changes color based on acidity.

Sensor or Probe

A device that detects and responds to environmental changes.

Alveoli

Tiny air sacs in the lungs that allow for gas exchange.

Respiration

The process by which living things obtain energy from food and oxygen.

Inhale

The act of taking in air through the lungs.

Exhale

The act of pushing air out of the lungs.

Cellular Respiration

The process where cells break down food using oxygen to create energy (ATP).

Metabolic Reaction

The chemical processes that allow cells to function and stay alive.
