Liver of Dog
Liver of Dog weighs about 3% of the body weight. It consists of five lobes -Right Lateral, Central, Caudate, Lt-central and Lt-lateral divided by fissures, which converge towards the portal fissure.
- The left lateral lobe is largest and is oval
- The left central lobe is prismatic
- The right central lobe is second in size and presents a tongue-shaped quadrate lobe divided from it by a deep fissure in which the gall bladder is lodged
- The right lateral is third in size and is oval. On its visceral face is the
- Caudate lobe made up of a caudate process on the right and a papillary process on the left
The parietal surface is convex and is related to the diaphragm and the adjacent part of the inferior wall of abdomen. The visceral surface is concave and presents the large gastric impression on the left lateral lobe. The portal fissure is between the papillary and caudate lobes.
The dorsal border presents a deep renal impression for the right kidney on the caudate lobe and medial to it, the caudal vena cava passes in a deep groove then continues on the parietal face of right lateral and central lobes. Next to the caudal vena cava, the dorsal border presents a large oesophageal notch.
The ventral border lies on the floor of abdomen at a variable distance behind the xiphoid cartilage. The gall bladder lies between the two parts of the right central lobe.
