Liver is called the reticular gland because

  1. The shape is reticular

  2. It contains reticular tissue

  3. Lobules branches and anastomose with one another to form a network

  4. Hepatic duct and cystic duct unite to form the bile duct
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • The liver is an organ that is present on the right side of the stomach.
  • Liver tissue is made up of lots of smaller units of liver cells called lobules. Many canals carrying blood and bile run between the liver cells. 
  •  Reticular fibre is a type of fibre in connective tissue. It is composed of type III collagen secreted by reticular cells. Reticular fibres crosslink to form a fine meshwork(reticulin). 
  • This network acts as a supporting mesh in soft tissue such as liver, bone marrow and the tissues and organs of the lymphatic system. Hence, the Liver is called the reticular gland because it contains reticular tissue.
So, the correct answer is 'It contains reticular tissue'.
