The function of blood is to

  1. Absorb nutrients

  2. Transport gases

  3. Produce food

  4. Both B and C


Correct Option: B
Explanation:

Blood performs many important functions within the body. These functions include the supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells), the supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins e.g., blood lipids), transport of gases etc.

Therefore, the correct answer is option B.

By what name is the liquid medium of blood Known as?

  1. waste (excretory) substance

  2. Blood particle

  3. plasma

  4. Waste material


Correct Option: A

How blood maintains water balance in the body ?

  1. By regulating the pH of the body

  2. By bringing constant exchange of water between circulating blood and tissue fluid

  3. By transporting the excretory material

  4. All of the above


Correct Option: B
Explanation:

Blood maintains water balance in the body by bringing constant exchange of water between circulating blood and tissue fluid. Regulating pH and transportation of excretory material are other functions performed by blood.

Blood carries

  1. Oxygen

  2. Waste

  3. Food

  4. All of the above


Correct Option: D
Explanation:
The blood transports oxygen from the lungs to the cells of the body, where it is needed for metabolism. Blood also provides the cells with nutrients, transports hormones and removes waste products
So, the correct answer is 'All of the above'

What fraction of your body is water? 

  1. 1/4

  2. 2/3

  3. 1/2

  4. 1/3


Correct Option: B
Explanation:

About 2/3 of the average human body is water, mostly within the cells. The amount of water in the human body ranges from 50-75%. The average adult human body is 50-65% water, averaging around 57-60%. The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age. Thus, option B is correct.

Substances transported by blood are..............

  1. Food materials

  2. Excretory materials

  3. Hormones

  4. All of the above


Correct Option: D
Explanation:
Blood Is an important fluid connective tissue which circulates throughout the body. It transports food, waste, hormones, oxygen etc. throughout the body.

Which of the following is not a function of blood ?

  1. Transport of food materials

  2. Transport of oxygen

  3. Transport of excretory materials

  4. None of these


Correct Option: D
Explanation:

Blood Is an important fluid connective tissue which circulates throughout the body. It performs some very important functions like transport of oxygen from lungs to the cells, transport of food material, Transport of excretory material, Transport of other substances and Transport of cell wreckage. etc. 

How blood helps in the transport of heat ?

  1. It transports heat from alimentary canal to different body parts.

  2. Export heat from endocrine glands to the places of use.

  3. Allows transfer of heat from deeper tissues to the surface of the body where it can be lost.

  4. All of the above


Correct Option: C
Explanation:

Blood allows heat transfer of heat from deeper tissues to the surface of the body where it can be lost. Hormones are carried by blood from endocrine glands to place of use, Also glucose and other nutrients are transported from alimentary canal through blood to different cells in the body.

How blood maintains the physiological co-operation of the body?

  1. By changing the temperature of the body

  2. By producing nutrients

  3. By circulating from one part to other

  4. All of the above


Correct Option: C
Explanation:

The main function of the cardiovascular system is, therefore, to maintain blood flow to all parts of the body, to allow it to survive. Veins deliver used blood from the body back to the heart. In the lungs, the blood picks up oxygen that we breathe in and gets rid of carbon dioxide, which we breathe out.


So, the correct option is 'By circulating from one part to other'.

Which of the following is a function of blood?
(a) Transport of food materials.
(b) Transport of hormones.
(c) Transport of heat.

  1. One statement is correct.

  2. Two statements are correct.

  3. All statements are correct.

  4. No statement is correct.


Correct Option: C
Explanation:

Blood transports the digested food from the alimentary canal to the tissue. Blood also distribute hormones secreted by the endocrine glands. The blood helps in keeping the temperature of the body uniform by distributing heat. Thus option C is the correct answer.
