The Cell

The cell |
|
The cell is the building block of all biological structure. In this image a few polygonal cells of the liver are attached together. Each cell has a central dark nucleus which is embedded in a pinkish cytoplasm. The nucleus takes up approximately 1/5 to 1/6 of the volume of the cell. (Image courtesy of Barbara Banner M.D.) 13440 |
The Tissue
|
Cells Align and Combine – Sinusoids – Shapes – New Unit – Tissue |
|
The cells of the liver are organized in cords and plates and are organized like spokes of a wheel around the central vein. The plates and cords are lined by the sinusoids which are the channels which carry blood to the liver. Just below the sinusoids, between the wall of the sinusoid and the capsule of the liver there is a space called the space of Disse which carries the lymphatic fluid of the liver. (Image courtesy |
Tissue Units
|
Tissue Aligns and Combines – Shapes – New Unit – Lobule |
|
The sinusoids and hepatic cords combine to form a liver lobule which is a functional and structural unit of the liver. At the center of the lobule is the central vein from which emanate many cords of liver tissue. At the periphery of the lobule there are 4-5 groups of portal triads consisting of distal branches of the portal vein (dark blue), hepatic artery (red) and biliary radicle (green). They create the border of the lobule. (Image courtesy of Ashley Davidoff M.D.) 13009 W |
Organs
|
Lobules Align and Combine – Shapes Up – New Unit – The The liver |
|
The lobules of the liver combine to form lobes. The liver has two lobes. In this anatomical specimen the right lobe is seen on the left side of the image lateral to the stone containing gallbladder, while the left lobe is seen with the branching potal triad surrounded by the whitened connective tissue. on the right side of the image.

Lobules Align and Combine – Shapes Up – New Unit – The The liver

In this anatomical specimen the right lobe is seen on the left side of the image lateral to the stone containing gallbladder, while the left lobe is seen with the branching potal triad surrounded by the whitened connective tissue. on the right side of the image.

Tissue Aligns and Combines – Shapes – New Unit – Lobule
The sinusoids and hepatic cords combine to form a liver lobule which is a functional and structural unit of the liver. At the center of the lobule is the central vein from which emanate many cords of liver tissue. At the periphery of the lobule there are 4-5 groups of portal triads consisting of distal branches of the portal vein (dark blue), hepatic artery (red) and biliary radicle (green). They create the border of the lobule.

Cells Align and Combine – Sinusoids – Shapes – New Unit – Tissue
The cells of the liver are organized in cords and plates and are organized like spokes of a wheel around the central vein. The plates and cords are lined by the sinusoids which are the channels which carry blood to the liver. Just below the sinusoids, between the wall of the sinusoid and the capsule of the liver there is a space called the space of Disse which carries the lymphatic fluid of the liver. (Image courtesy
