Most of the total body weight of an animal consists of (a) Water. Water is a fundamental component of living organisms, constituting a substantial proportion of an animal’s body mass. It serves essential roles in biological processes, including hydration, nutrient transport, waste removal, and temperature regulation. Water forms the basis of bodily fluids, such as blood, lymph, and digestive juices, facilitating various physiological functions. While blood, bone, and tissues are crucial components of an animal’s body composition, they collectively make up a smaller proportion compared to water. Blood primarily consists of plasma and cells, bone provides structural support and mineral storage, and tissues comprise cells organized into specialized structures performing specific functions. However, water surpasses them all in terms of sheer volume, making it the predominant constituent of an animal’s body weight and indispensable for sustaining life and metabolic activities.
