Answer 1

The liver is the largest, internal and diverse metabolically complicated organ in humans. The human liver is involved in many different functions. In the human body, the liver is located in the upper right area of the abdomen, below the rib cage and the lungs. The liver is a solid organ, which is weighted nearly 3–3.5 pounds or 1493.79 grams.

Complete step by step answer: The liver is reddish-brown in color with a rubbery type texture. The liver is triangular and has two lobes; a larger right lobe and a smaller left lobe. The lobes are parted by the falciform ligament. It is 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. This capsule is further covered by the peritoneum, a membrane that forms the lining of the abdominal cavity. This helps the liver to keep in place and protects it from any physical damage. Liver cells contain a nucleus and they possess a cell membrane, but not a cell wall. It has two main sources of blood:
a. Hepatic Portal Vein – it carries nutrient-rich blood from the digestive system.
b. Hepatic Artery – it carries oxygenated blood from the heart.
Hence, the correct answer is option C.

Note: The liver is the only organ which has the ability to regenerate efficiently. The most important functions of the liver are listed below:
i. It produces and excretes bile.
Ii. It detoxifies the blood and purifies it.
iii. It acts as a blood clotting factor.
iv. Produce proteins for blood plasma.
