Question

The liver is:
A. A reddish brown
B. A reddish
C. A brown
D. Cream coloured

Answer 1

Hint:-The liver is an organ only found in vertebrates which detoxifies various metabolites, synthesizes proteins and produces biochemicals necessary for digestion and growth. 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.

Complete step-by-step solution:-
The liver is a reddish Brown, which is shaped like an organ with two lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kilogram and has a width of about 15 centimeter. There is considerable size variation between individuals, with the standard reference range from men being 972-1860 gram and for women 600- 1770 gram . It is both the heaviest internal organ and the largest gland in the human body.
So, the correct answer is option A.

Additional information:- The liver is connected to two large blood vessels , the hepatic artery and the portal vein. The hepatic artery carries oxygen rich blood from the aorta via the celiac trunk whereas the portal vein carries blood reaching digested nutrients from the entire gastrointestinal tract and also from the spleen and pancreas. These blood vessels subdivide into small capillaries known as liver sinusoids , which then lead to lobules.

Note:- Lobules are the functional units of liver. Each lobule is made up of millions of hepatic cells known as him hepatocytes, which are the basic metabolic cells. The lobules are held together by a fine, dense, irregular fibro elastic connective tissue layer extending from the fibrous capsule covering the entire liver known as Glisson’s capsule.
