Which of the following can be classified as body fluids?

Air
Blood and saliva
Metal particles
Plastic substances

The correct answer is: Blood and saliva

Body fluids refer to the liquid substances that circulate within living organisms and play vital roles in physiological functions. Blood and saliva are prime examples of body fluids, as they are essential for various bodily functions such as nutrient transport, waste removal, digestion, and immune response. Blood is a specialized fluid that carries oxygen, nutrients, hormones, and waste products throughout the body, while saliva aids in digestion and oral health by helping break down food and providing antimicrobial properties. These fluids are involved in critical processes necessary for maintaining homeostasis and overall health. The other options, while they may serve important roles in different contexts, do not fit the definition of body fluids. Air is a gaseous substance and does not consist of liquids. Metal particles and plastic substances are solid materials that are not involved in the biological processes of living organisms, justifying why they cannot be classified as body fluids.
