BIO NMDCAT Biological Importance of Water
nmdcat.online June 27, 2026

The physical property of water that allows for the transport of nutrients and gases in blood is its

A. High heat capacity, which maintains thermal gradients
B. Low viscosity, which facilitates fluid flow through narrow vessels
✓
C. High surface tension, which allows it to form droplets
D. Capacity to form ice at low temperatures

📝 Explanation

Viscosity is the internal resistance to flow. Water has a relatively low viscosity compared to other liquids like oils. This property allows blood (a water-based fluid) to be pumped efficiently through the cardiovascular system with minimal energy loss due to friction.
