While they are both responsible for phagocytosis and killing microorganisms, macrophages also activate T cells and initiate the immune response. They are also produced by different progenitors, (neutrophils by common granulocyte precursor and macrophages by and unknown precursor which then becomes a monocyte (immature macrophage)).
Hepatocytes make up the main part of liver tissue, and are involved in almost all of the main functions of the liver. This includes the synthesis of clotting factors and bile, the storage of lipids and glycogen, and the biotransformation of toxic substances and waste products.
Hepatic macrophages are called Kupffer cells. These line the sinusoids (small blood vessels) of the liver, and are responsible for the phagocytosis (engulfing) of debris and old red blood cells.

Process in which alcohol enters the boloodstream?
In the liver from hepatocytes (liver cells) in to the Hepatic sinusoids.
Where would you expect to find the hepatic macrophages of the liver?
Hepatic macrophages are special phagocytic cells, also called Kupffer cells, that line the sinusoids and remove debris from the blood.
Structural and functional unit of liver?
The structural unit of the liver is the hepatic lobule, which consists of hepatocytes arranged in radiating cords around a central vein. The functional unit is the liver acinus, which is a specific zone within the hepatic lobule responsible for performing metabolic functions such as detoxification, protein synthesis, and glycogen storage.
What is hepatic tissue?
Hepatic tissue refers to the tissue found in the liver, which is responsible for various functions such as detoxification, metabolism, and storage of nutrients. It is made up of hepatocytes, which are the main functional cells of the liver. Hepatic tissue plays a crucial role in maintaining the body's overall health and well-being.
What is the difference between renal and hepatic circulation?
Renal circulation, receiving about 20% of cardiac output, branches from the abdominal aorta and returns to the ascending vena cava. Hepatic circulation is the system of veins made of the hepatic portal vein and its tributaries.
How does bile leave the hepatocytes?
The bile produced by hepatocytes drains into canaliculi, which are small channels that take the bile to the bile ductules. These eventually merge to become the common bile duct, which opens into the duodenum (the first part of the small intestine).
What is the path of bile from its secretion to the gallbladder for storage and concentration and then to the duodenum listing the structures in order?
a. hepatocytes b. bile canaliculi c. bile ducts d. left & right hepatic ducts e. common hepatic duct f. cystic duct g. gallbladder h. cystic duct i. common hepatic duct j. hepatopancreatic ampulla k. duodenum
What cells do you have in the liver?
hepatic cells.
Is hepatic liver cancer the same as heptaocellular carcinoma of the liver?
Yes, "hepatic liver cancer" and "hepatocellular carcinoma (HCC) of the liver" are referring to the same condition. Hepatocellular carcinoma is the most common type of primary liver cancer, and it specifically refers to cancer that begins in the hepatocytes, which are the main type of liver cells. "Hepatic" simply means "related to the liver," so "hepatic liver cancer" is another way to describe hepatocellular carcinoma or liver cancer that originates in the liver cells.
The functional unit of the liver is known as?
the hepatic lobule is the structural and functional unit of the liver. there are about 50,000 - 1,00,000 lobules in the liver. the lobule is a honey comb like structure and it is made up of liver cells called hepatocytes.
What organ contains lobules with sinusoids that lead to a central venous structure?
The liver contains lobules with sinusoids that lead to a central vein called the central vein or hepatic vein. Each lobule is made up of hepatic cells (hepatocytes) arranged around a central vein, which functions to drain blood from the sinusoids in the lobule.
Trace the flow of bile from the liver to the duodenum listing all of the structure that come into contact with the bile on its journey.?
The hepatocytes in the liver produce bile, which then flows through the left and right hepatic ducts to the common hepatic duct. Once the common hepatic duct is filled, the bile flows into the cystic duct and then into the gallbladder where it is stored. The gallbladder allows the bile to flow back into the cystic duct and then the common bile duct which empties into the duodenum.
