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)).

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).
Where is the stellate macrophages of the liver?
Stellate macrophages of the liver, also known as Kupffer cells, are located in the liver sinusoids, which are specialized blood vessels within the hepatic tissue. They play a crucial role in the immune response by phagocytosing pathogens and debris in the bloodstream. Kupffer cells are positioned strategically to monitor blood as it flows from the portal vein and hepatic artery, allowing them to perform their functions effectively.
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.
How do hepatocytes divide?
Hepatocytes, the main functional cells of the liver, primarily divide through mitosis. In response to liver injury or increased demand for hepatic function, these cells can undergo a process called compensatory hyperplasia, allowing for regeneration. Hepatocytes are capable of entering the cell cycle from a quiescent state, and their ability to replicate is influenced by various growth factors and cytokines. However, they typically maintain a stable size and number under normal conditions, only proliferating when necessary.
What is hapatic parnchyma?
Hepatic parenchyma refers to the functional tissue of the liver, primarily composed of hepatocytes, which are the main liver cells responsible for various metabolic processes, detoxification, and bile production. This tissue is organized into lobules that facilitate the efficient exchange of substances between the blood and liver cells. The health and functionality of the hepatic parenchyma are crucial for overall liver function and metabolism. Damage to this tissue can lead to liver diseases and impaired metabolic functions.
