The study of the structure of the body.

The study of the function of the body's structures.

Anatomy and physiology are interdependent; structure influences function and vice versa.

The visual examination of the body's appearance.

Feeling a structure with the hands to examine it.

Listening to sounds produced by the body to assess health.

Tapping on the body to feel for resistance or listen for sounds.

Cutting and separating body tissues to study their relationships.

The process of maintaining internal stability in the body despite external changes.

A mechanism that reverses a change to maintain homeostasis, keeping variables close to a set point.

The widening of blood vessels to increase blood flow and release heat when the body is too warm.

The narrowing of blood vessels to decrease blood flow and retain heat when the body is too cold.

The process by which the body maintains its internal temperature within a narrow range.

A group of similar cells performing a specific function in an organ.

The simplest unit of life that is considered alive.

Microscopic structures within a cell that perform individual functions.

A mechanism that amplifies a change in a process.

Properties that distinguish living things from nonliving, like organization and metabolism.

Differences in physiological traits among individuals, influenced by various factors.

The change in form or function of an organism over time.

The biological process of producing offspring to pass on genes.

A mechanism that regulates blood pressure via feedback loop.

Structure that senses changes in the body.

Control center that processes sensory information and directs a response.

Cell or organ that executes corrective actions to restore homeostasis.

Childbirth, blood clotting, and nerve signal generation are instances of positive feedback.

Anatomy and physiology cannot be separated; they work together.

All structure and function results from cellular activity.

The human body is shaped by evolutionary processes.

Human structure is organized in levels of increasing complexity.

Matter and energy flow down gradients.

A medical imaging technique using X-rays to view internal structures.

A technique to visualize blood flow and blockages using X-ray images.

A medical imaging technique using low-intensity X-rays and computer analysis to create slice-type images.

An imaging technique that uses magnets and radio waves to create high-quality images, particularly of soft tissues, without X-ray exposure.

A type of MRI that shows real-time changes in brain activity by measuring blood flow.

An imaging test that assesses the metabolic state of tissues using radioactively labeled glucose.

A method of visualizing cross-sections of the body, commonly used in CT scans.

Glucose that has been tagged with a radioactive element, used in PET scans to evaluate tissue metabolism.

The process of capturing images of non-bony parts of the body, best done with MRI.

The ability to observe the brain’s activity and response live, often through techniques like fMRI.
