Body
The body refers to the physical structure that contains and supports the vital organs of an organism, including humans.
Key Concepts
Several key concepts are essential to understanding the human body:- Anatomy: The study of the structure and organization of living organisms.
- Physiology: The study of the functions and processes that occur within living organisms.
- Homology: The shared characteristics between different species or structures.
- Developmental biology: The study of how living organisms develop from embryonic stages to adulthood.
Understanding these concepts is crucial for grasping the complexities of human health and disease.
Technical Details
The human body consists of approximately 37.2 trillion cells, with an estimated 60-70% of body mass composed of water (5). The average adult human has a heart rate of around 72 beats per minute, while the brain consumes approximately 20% of total energy expenditure (6).- Human genome: The complete set of genetic instructions encoded in an organism's DNA.
- Mitochondria: Organelles responsible for generating energy through cellular respiration.
- Nervous system: A complex network of neurons and glial cells that transmit and process information.
These technical details provide insight into the intricate mechanisms that govern human biology.
