What is the relation between the viscosities of blood and water?a)Both...
- Viscosity is a measure of resistance to flow which arises due to the internal friction between layers of fluid.
- This resistance to fluid motion is like internal friction analogous to friction when a solid moves on a surface.
- Strong intermolecular forces between molecules hold them together and resist the movement of layers past one another.

What is the relation between the viscosities of blood and water?a)Both...
Relation between the viscosities of blood and water:
Blood and water are both fluids, but they have different viscosities. Viscosity is a measure of a fluid's resistance to flow and is influenced by factors such as temperature, composition, and molecular interactions. In the case of blood and water, their viscosities are different, with blood being more viscous than water.
Explanation:
Blood is a complex fluid that consists of various components, including red blood cells, white blood cells, platelets, and plasma. These components contribute to the viscosity of blood. The presence of red blood cells, which are responsible for transporting oxygen throughout the body, significantly affects the viscosity of blood.
Red blood cells are disc-shaped and flexible, but they can stack on top of each other and form a column-like structure in the bloodstream. This phenomenon is known as rouleaux formation. The interaction between red blood cells and plasma proteins, such as fibrinogen, contributes to the viscosity of blood. The aggregation of red blood cells and the resistance they create while flowing through blood vessels result in a higher viscosity compared to water.
On the other hand, water is a simple fluid consisting of H2O molecules. It has a lower viscosity compared to blood due to the absence of cellular components and plasma proteins. The molecules in water are not as closely packed as red blood cells, leading to less resistance to flow.
Therefore, based on the composition and cellular components, blood is more viscous than water. The viscosity of blood is essential for its proper functioning, as it allows for the efficient flow of blood through the narrow capillaries and ensures adequate oxygen and nutrient delivery to the body's tissues.
In conclusion, the correct answer is option 'C': Blood is more viscous than water.
