The following simplified diagram refers to the outline plan of the circulation of blood in a mammal. Study the diagram and write the number and the name of the blood vessel in each case as mentioned ahead.
(a) Several hours after a meal containing a lot of protein, which vessel will contain the highest concentration of urea?
(b) Which vessel would contain the highest concentration of amino acids and glucose soon after a meal?,
(a) Hepatic vein (7) will contain the highest concentration of urea. (liver produces urea & other waste materials & then pours it all in the right auricle of the heart from where it is transferred to right ventricle & then lungs for oxygenation)
(b) Hepatic portal vein would contain the highest concentration of amino acids and glucose soon after a meal as hepatic portal vein starts from intestine and stomach and ends in liver.
