What organelles are in the liver?
The two main cell organelles of the liver, the mitochondria and the endoplasmic reticulum, comprise about 80% of the total liver protein.
Why do liver cells have a lot of smooth endoplasmic reticulum?
Large amounts of smooth ER are found in liver cells where one of its main functions is to detoxify products of natural metabolism and to endeavour to detoxify overloads of ethanol derived from excess alcoholic drinking and also barbiturates from drug overdose.
Do liver cells have a lot of ER?
Liver cells have an impressive network of smooth endoplasmic reticulum. Similarly, cells of the ovaries and testes, which produce the lipid-containing hormones estrogen and testosterone, contain large amounts of smooth endoplasmic reticulum.
Where are liver cells found?
In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm. Its other roles in metabolism include the regulation of glycogen storage, decomposition of red blood cells, and the production of hormones.
How big is a liver cell?
Normal Liver and Gallbladder. Hepatocytes constitute the predominant cell type of a normal liver (Fig. 9-1A&B). They are slightly oval to polygonal plump cells, with a diameter of 25 to 30 μm (approximately 3 to 4 erythrocyte diameters).
Why do liver cells have lots of ribosomes?
Liver cells contain more ribosomes than fat cells because the liver is an organ in which much protein synthesis occurs, and ribosomes are the cell…
What are the main organelles in a liver cell?
What does a liver cell contain? The main organelles in the Liver cell are: the Nucleus, DNA, RNA and the cytoplasm. The Nucleus contains DNA, and acts as a control center for the cell .
What do liver cells have a lot of?
The main organelles in the Liver cell are: the Nucleus, DNA, RNA and the cytoplasm. The Nucleus contains DNA, and acts as a control center for the cell. All cells contain the same copy of DNA cells.
Why do liver cells have a lot of smooth ER?
In addition, smooth ER is abundant in the liver, where it contains enzymes that metabolize various lipid-soluble compounds. Additionally, what organelles do liver cells have a lot of? Hepatocytes comprise the principle cell population in the liver.
What do hepatocytes do in the blood stream?
Hepatocytes must be able to make contact with the blood stream. They do this in areas known as sinusoids. Also in the sinusoids are specialized “trash collector” cells known as Kupffer Cells. These cells serve to clean up junk and swallow up foreign invaders such as bacteria and viruses. They do this by literally swallowing their target. Yummy!
