What tissue is the liver composed of?
The liver is made of very soft, pinkish-brown tissues encapsulated by a connective tissue capsule. This capsule is further covered and reinforced by the peritoneum of the abdominal cavity, which protects the liver and holds it in place within the abdomen.
Is the liver a group of tissues?
Liver tissue consists of a mass of cells tunneled through with bile ducts and blood vessels. Hepatic cells make up about 60 percent of the tissue and perform more metabolic functions than any other group of cells in the body.
What is the structure of the liver?
The liver is roughly triangular and consists of two lobes: a larger right lobe and a smaller left lobe. The lobes are separated by the falciform ligament, a band of tissue that keeps it anchored to the diaphragm. A layer of fibrous tissue called Glisson’s capsule covers the outside of the liver.
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.
What kind of epithelium is the liver made of?
It will be made of simple cuboidal epithelium (arrow). Liver, Human – 400X Bile ducts (bd) collect bile from the liver lobules and take it out of the liver. Where you see a small bile duct like this, you may also be able to find a small artery (bv) and a small vein.
How are the cells of the liver arranged?
The liver can be confused with other organs that contain mainly small cells of glandular epithelium, such as the pancreas. Most of the pancreatic cells are arranged in small spherical secretory units that look like circles when sectioned.
What is the microscopic structure of the liver?
Microscopic structure of the liverLiver cells, or hepatocytes, have direct access to the liver’s blood supply through small capillaries called sinusoids. Hepatocytes carry out many metabolic functions, including the production of bile.
How is liver tissue used in biochemical studies?
Andrew J. Connolly MD, PhD, in Autopsy Pathology (Second Edition), 2009 Tissue (liver, brain, kidney, cardiac muscle, skeletal muscle, peripheral nerve) obtained at autopsy may be used for biochemical studies in the diagnosis of inborn errors of metabolism.
