Question

Urea is transported by
A. Plasma
B. RBC
C. WBC
D. All of the above.

Answer 1

urea is the waste product that is produced in the body, so this should be eliminated or excreted out of the body in order to maintain the metabolic activities and harmony of the body, this byproduct should be excreted.

Complete answer:
In the body, blood is made up of several components, which include the different types of cells, such as RBC, WBC, and platelets, etc
Along with the solid components, blood also contains a liquid portion called plasma
Plasma has a very important role in transport, it transports all nutrients produced in the body to different body parts.
At the same time, it also collects the waste products produced during the regular metabolism from all body organs and excretes out of the body.
So urea is also eliminated from the body by plasma
And plasma plays an important role in maintaining the blood pressure.
Where as other given options are WBC and RBC they have their own role in the blood
They are major components, when it comes to RBC they have hemoglobin and have an essential role in carrying the oxygen and carbon dioxide to body parts.
WBC are immune cells, they play a vital role in maintaining body immunity, whenever the foreign particle enters the body, they are identified and protects the body from all disease-causing organisms.
So RBC and WBC do not have any role in the transport of urea.

So, the correct option: A. Plasma.

Note:
Blood is the major component of the body, each type of cells have their unique role, so it’s good to know every function of each component. If urea isn't eliminated from the body, it causes an increase in the acid nature of blood so it is important to excrete it out.
