•  The liver is digestive glands situated outside the digestive tract.
• The liver is the largest gland of the human body.
•  It weighs about 1.2 to 1.5 kg in an adult human, so option B is correct

The liver is the body's largest gland. An adult human liver weighs between 3.2 and 3.7 pounds. The right lobe of the liver is the largest and is six times larger than the left lobe.

Kupffer cells, also known as Browicz-Kupffer cells are specialized macrophages located in the liver lining the walls of the sinusoids that form part of the reticuloendothelial system. Red blood cells are broken down by phagocytic action of Kupffer cells, where the hemoglobin molecule is split. The globin chains are re-utilized, while the iron-containing portion, heme, is further broken down into iron, which is re-utilized, and bilirubin, which is conjugated to glucuronic acid within hepatocytes and secreted into the bile.

In mammalian bodies, Kupffer cells are the most abundant tissue macrophages as they constitute 80-90% of them. Also known as Kupffer-Browicz cells or stellate macrophages; these specialized macrophages are specifically found in the liver.

• Each lobule in the liver is made up of millions of hepatic cells, which are the basic metabolic cells. 
• These lobules are held together by a fine, dense, irregular, fibroelastic connective tissue layer which extends from the fibrous capsule covering the entire liver known as Glisson's capsule.
•  Glisson's capsule forms a layer of connective tissue surrounding the liver and ensheathing the hepatic artery, portal vein, and bile ducts within the liver. Hence, Glisson's capsule is associated with the liver.

Liver is the largest gland of the body weighing about 1.2 to 1.5 kg in an adult human. It is situated in the abdominal cavity, just below the diaphragm and has two lobes. The hepatic lobules are the structural and functional units of liver containing hepatic cells arranged in the form of cords. Each lobule is covered by a thin connective tissue sheath called as the Glisson's capsule.

Kupffer cells, also known as Browicz-Kupffer cells are specialized macrophages located in the liver lining the walls of the sinusoids that form part of the reticuloendothelial system. 

• In vertebrates, the gallbladder is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. 
• In humans, the pear-shaped gallbladder present on the right lobe of the liver that lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. Hence, Gallbladder is found in

Kupffer cells are specialized macrophages located in the liver lining the walls of the sinusoids, that form part of the reticuloendothelial system.

Liver is the largest gland of human body. Liver sinusoids are lined by the endothelial cells mostly but a few macrophages cells are also present. These are called as Kupffer's cells (phagocytic cells).
