Question

state the function of following transport system
1.Blood
2.lymph

Answer 1

1) transport oxygen and other nutrients. also maintains pH level of body

2) it helps in transportation of absorbed fats from intestine and drains excess fluid from extracellular spaces back into blood

Answer 2

Functions of Blood System:-

Transport: to and from tissue cells 

• Nutrients to cells: amino acids, glucose, vitamins, minerals, lipids (as lipoproteins). 

• Oxygen: by red blood corpuscles (oxyhaemoglobin - 4 x O2

molecules/haemoglobin). 

• Wastes from cells: urea, CO2 (mainly as HCO3

-

 in solution in the plasma). 

Temperature Regulation: by altering the blood flow through the skin. 

Immunity: protection against pathogens — blood clotting; phagocytes, lymphocytes and antibodies 

distributed in blood. 

Communication: hormones distributed to all parts of the body in the blood. 

Defence: clotting following a wound 

 

 Functions of the Lymphatic System:

Circulatory role 

• Return the excess tissue fluid to the blood: this maintains blood volume, pressure and 

concentration. 

• Collect and deliver the absorbed lipids from the small intestine to the blood 

Defence role 

• The lymph nodes filter out pathogens in the lymph. 

• Production and ‘export’ of lymphocytes to the blood system for general distribution. 

• Detection of antigens and production of specific antibodies
