Question

In our circulatory system, blood transports blood cells and dissolved ions when it moves through the body.

Which of the following terms is suitable for blood?

Solution
Suspension
Colloid

Answer 1

I think the correct answer from the choices listed above is the second option. The term that best suit for blood would be suspension. Solutions are for homogeneous mixtures which blood obviously isn't, and colloids are also homogeneous mixtures with a dispersed phase and a continuous phase. So, it must be suspension.

Answer 2

Answer: Suspension

Blood is a liquid connective tissue which flows all over the body of animal body including human. Blood can be characterized as three forms of mixtures that are solution, colloid and suspension. Blood is a solution as it dissolves within it substances such as salts, urea, gases, glucose and others. It is a colloid because it is composed of plasma proteins, such as albumin, transport proteins and antibodies. Blood can also be considered as suspension because it consists if blood cells and platelets.

According to the given situation, the blood transports blood cells and dissolved ions. The presence and transportation of blood cell indicates that it is a suspension.
