Human Body Concept Map

Metabolism is the set of chemical processes that occur in living organisms to maintain life, including converting food into energy, building and repairing tissues, and removing waste products. It is divided into catabolism (breaking down molecules for energy) and anabolism (using energy to build molecules).

Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes, regulating conditions like temperature, pH, and blood sugar through feedback mechanisms.

Organ systems are groups of organs that work together to perform major functions in a living organism, such as the digestive, respiratory, circulatory, and nervous systems, all interacting to keep the body functioning.

Physiology is the branch of biology that studies how living organisms function, focusing on the normal processes of cells, tissues, organs, and body systems to understand how the body maintains life and responds to changes.

Anatomy is the study of the structure of living organisms, focusing on the parts of the body and how they are arranged, such as organs, tissues, bones, and muscles.

Catabolism is the part of metabolism that breaks down complex molecules into simpler ones, releasing energy in the process, often associated with digestion and cellular respiration.

Anabolism is the part of metabolism that uses energy to build complex molecules from simpler ones, such as proteins and lipids, and is associated with growth, repair, and synthesis of biomolecules.

Metabolic rate is the amount of energy the body uses to maintain basic functions like breathing, circulation, and temperature regulation. It is influenced by factors such as age, sex, body size, and muscle mass.

ATP (adenosine triphosphate) is the main energy-carrying molecule in cells, acting as a usable energy currency. The chemical energy stored in food is converted into ATP during digestion and cellular respiration, which cells then use to power cellular processes.
