Final answer:
Approximately 50 - 70% of the human body is composed of fluid, which is distributed throughout the body in different compartments.
Step-by-step explanation:
The human body is composed of approximately 50 - 70% fluid. This fluid is distributed throughout the body, including within cells and between cells in tissues and organs. The intracellular fluid amounts to about 50% of body weight in lean individuals, while extracellular fluids represent about 20% of body weight, with 15% in the interstitial fluid and 5% in blood plasma. Approximately 50 - 70% of the human body is composed of fluid. This fluid is distributed between intracellular compartments (fluid within cells) and extracellular compartments (fluid outside cells). Water is essential for various physiological functions, including digestion, absorption, circulation, and temperature regulation. The percentage can vary across individuals based on factors such as age, sex, and overall health. Infants and young children generally have a higher percentage of body water compared to adults. Adequate fluid intake is crucial for maintaining hydration, supporting organ function, and sustaining overall health. Balancing fluid levels is vital for proper cellular function and maintaining homeostasis.
