Explanation / Answer

Option e is right one

The absorbed water soluble drug from the intestine reaches into the PORTAL VEIN; where it contains oxygen depleted blood carries it into liver

Immediately before reaching the liver portal vein is divided into right and left PORTAL VENULE and it courses along side and forms the vascular components of the portal triad

Hence these veins empty into hepatic SINUSOIDS to supply blood to the liver which further passes to the CENTRAL VEIN which drains it into hepatic vein

From hepatic vein, it leads into superior venacava where the blood reaches in HEART AND LUNGS further it reaches into the BRAIN

3; The option e is true

4 option b is the right answer

LUMEN OF LIVER SINUSOID BLOOD LUMEN OF BILE DUCT BILE LUMEN OF HEPATIC ARTERY BLOOD LUMEN OF GALL BLADDER BILE LUMEN OF CYSTIC DUCT BILE HEPATIC MACROPHAGE BLOOD HEPATOCYTE BOTH BLOOD AND BILE LUMEN OF DUODENUM NEITHER BILE OR BLOOD LUMEN OF CENTRAL VEIN OF LIVER LOBULES BLOOD LUMEN OF PORTAL VENULE BLOOD LUMEN OF HEPATIC PORTAL VEIN BLOOD
