Which is the only organ in the human body that can regrow and regenerate?

Option 3 : Liver

The correct answer is option 3 i.e.,  Liver.

• The Liver is the only organ in the human body that can regenerate.
• The liver is both exocrine and endocrine glands and it produces an enzyme called bile juice.
• Bile is used to churn fats in the stomach.
• The liver is the largest gland in the body.
• Malfunction of the liver can cause diseases like Hepatitis A and Hepatitis B.
• Spleen: It is also known as the “graveyard of blood” as it filters the blood by removing microbes and worn-out RBCs.

  To be more specific, it's produced by the beta cells in the islets of Langerhans in the pancreas.
• When we eat, the glucose level rises, and insulin is released into the bloodstream.
