Question

Blood is an example of?

Answer 1

Hint: We need to know that a sol is a colloid made out of very small solid particles in a continuous liquid medium. Sols are quite stable and show the Tyndall effect. Examples include blood, pigmented ink, cell fluids, paint, antacids and mud. Artificial sols may be prepared by dispersion or condensation.

Complete answer:
Blood is a colloidal solution.
We need to know that blood is a solution of salts, glucose, urea and a few other small compounds. It's a colloid of plasma proteins, including albumin, transport proteins and antibodies. It's also a suspension of blood cells and platelets. Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.
In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes \[55\% \]of blood fluid, is mostly water (\[92\% \] by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. In its normal stable state, blood is a suspension, which is a colloid. It mainly consists of red & white blood cells, and lymphocytes suspended in plasma. Blood has the characteristic of both a colloid and a suspension making it a colloidal suspension. In its normal stable state, blood is a suspension, which is a colloid. It mainly consists of red & white blood cells, and lymphocytes suspended in plasma.

Note:
We have to remember that hemoglobin molecules normally form a colloidal suspension inside red blood cells, which typically have a “donut” shape and are easily deformed, allowing them to squeeze through the capillaries to deliver oxygen to tissues. Blood mainly consists of red & white blood cells, and lymphocytes suspended in plasma.
