CATEGORY 1: Anatomy vs. Physiology
This field studies the structure of body parts
Anatomy
The smallest units of living organisms
Cells
This system provides the body’s external covering
Integumentary system
The maintenance of stable internal conditions
Homeostasis
A chemical bond formed by the attraction between oppositely charged ions
Ionic Bond
This field studies how body parts function
Physiology
Groups of similar cells performing a specific function
Tissues
This system transports blood, oxygen, and nutrients
Cardiovascular system
The part of a feedback system that detects change
Receptor
The scale measuring acidity and alkalinity
pH scale
The plane that divides the body into anterior and posterior portions
Frontal (coronal) plane
Structures composed of two or more tissue types
Organs
This fast-acting control system includes the brain and spinal cord
Nervous system
The control mechanism that reverses a change
Negative Feedback
A reaction that releases energy, such as the breakdown of ATP
Exergonic reaction
The microscopic study of tissues
Histology
Organs that work together for a common purpose
Organ systems
This system produces hormones that regulate growth and metabolism
Endocrine system
This type of feedback amplifies the original stimulus
Positive feedback
The chemical reaction that breaks larger molecules by removing water
Dehydration synthesis
The serous membrane that surrounds the lungs
Pleura
The level representing the entire human body
Organism
This system eliminates nitrogenous wastes and regulates pH
Urinary system
Oxytocin increasing labor contractions is an example of this feedback
Positive Feedback
The relationship between acids, bases, and hydrogen ion concentration
Acids increase H⁺ while bases decrease H⁺
