Pancreas, Liver,and Gallbladder P2

Question 1

Pancreatic acini

Answer 1

99% of pancreatic tissue, comprising the exocrine portion of the gland, and producing the fluid and digestive enzymes that make up pancreatic juice

Question 2

hepatocyte

Answer 2

The functional cells of the liver make up 80% of the volume of the liver. They perform a huge range of metabolic, secretory & endocrine functions

Question 3

Sinusoidal capillary

Answer 3

The most porous capillaries running through the hepatic lobules. They allow most of the contents of the blood to move into the hepatic interstitial fluid

Question 4

Hepatic laminae

Answer 4

Rows of hepatocytes within a hepatic lobule. They run alongside hepatic sinusoids and bile canaliculi

Question 5

Bile canaliculi

Answer 5

Small bile ducts running among the hepatocytes that collect produced bile and convey it to bile ductules, and eventually to bile ducts

Question 6

Central vein

Answer 6

The primary vein of a hepatic lobule, collecting blood from sinusoid capillaries and moving it to the hepatic vein

Question 7

Hepatic vein

Answer 7

Collects venous blood from the central veins of the liver and conducts it to the inferior vena cava

Question 8

Hepatic artery

Answer 8

Primary arterial branch serving the liver. It’s one of the 3 branches of the celiac trunk

Question 9

Hepatic portal vein

Answer 9

The “other “ source of afferent blood to the liver!! It brings blood from the capillary beds of the intestine to the liver

Question 10

Bile duct

Answer 10

Collects bile from the bile canaliculi (via bile ductules). Eventually, they flow into the left and right hepatic ducts and into the common hepatic duct

Question 11

Portal triad

Answer 11

The combination of one bile duct, one hepatic artery, and one hepatic portal vein. It’s the central structure of a hepatic acinus

Question 12

Stellate reticuloendothelial cell

Answer 12

Fixed phagocytes sitting within sinusoid capillaries of the liver, breaking down pathogens and worn-out blood cells

Question 13

Hepatic acinus

Answer 13

Currently accepted functional unit of the liver. Bordered by two central veins laterally, with a portal triad running through the center. Zone 1 is hepatocytes, hepatic laminae, bile canaliculi, and sinusoids closest to the center portal triad. Zone 3 is the same structure furthest from the portal triad - closet to the central veins. Zone 2 structures are between Zone 1 and Zone 3 in location and function.
