The Islets of Langerhans are the clusters of endocrine cells scattered throughout the pancreas that secrete hormones like insulin and glucagon.

Kupffer cells are found in liver sinusoids (a-q). Beta-cells are in the Islets of Langerhans (b-p). Brush border cells are in the small intestine (c-t). Paneth cells are also in the small intestine (d-t). Note: The provided option D matches a-q and b-p, which are correct.

The pancreas is a heterocrine gland, meaning it has both exocrine functions (secreting digestive enzymes) and endocrine functions (secreting hormones).

Renin is an enzyme secreted by the juxtaglomerular cells of the kidney, not the pancreas. Insulin, glucagon, and somatostatin are all produced by the endocrine pancreas.

The liver is the primary site for the urea cycle, where toxic ammonia produced by protein metabolism is converted into urea for excretion.

Pancreatic juice contains nucleases, specifically DNA-ase and RNA-ase, which break down nucleic acids into nucleotides.

The liver is the largest internal organ and the largest gland in the human body.

The Islets of Langerhans are the endocrine cell clusters found within the pancreas.

The human liver is anatomically divided into four lobes: the right, left, caudate, and quadrate lobes.
