Textbook Question

Which of the following is not a function of water?a. dispersing nutrients throughout the body;b. helping prevent cancer;c. helping to regulate body temperature;d. helping to regulate blood pressure

Verified step by step guidance

Step 1: Understand the functions of water in the human body. Water is essential for various physiological processes.

Step 2: Consider option (a): Dispersing nutrients throughout the body. Water is a major component of blood and lymph, which transport nutrients to cells.

Step 3: Consider option (b): Helping prevent cancer. While water is crucial for overall health, it does not directly prevent cancer.

Step 4: Consider option (c): Helping to regulate body temperature. Water is involved in thermoregulation through processes like sweating and evaporation.

Step 5: Consider option (d): Helping to regulate blood pressure. Water maintains blood volume, which is important for blood pressure regulation.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Functions of Water in the Body

Water plays several critical roles in the human body, including transporting nutrients, regulating temperature, and facilitating biochemical reactions. It acts as a solvent for various substances, ensuring that nutrients are effectively dispersed throughout the body. Understanding these functions is essential to evaluate the options presented in the question.

Nutrient Transport

One of the primary functions of water is to act as a medium for transporting nutrients and waste products in the bloodstream. This process is vital for maintaining cellular function and overall health, as it ensures that essential nutrients reach cells while removing toxins. Recognizing this function helps clarify why option 'a' is a valid function of water.

Thermoregulation

Water is crucial for thermoregulation, which is the body's ability to maintain a stable internal temperature. It absorbs heat and helps dissipate it through processes like sweating. This concept is important for understanding why option 'c' is a function of water, while also allowing for the evaluation of the other options in the context of water's roles.
