The liver, it's the largest visceral tissue mass in the human body and consists of four lobes.

Those lobes are the right, left, quadrate, and caudate lobes.

The liver can weigh up to 2 kilograms and can make up about 2% of a human's overall body weight.

The right lobe is the largest and fills the majority of the right upper quadrant of the abdomen,

and the left lobe is much smaller and takes up the median part.

The blood supply of the liver is made up of the portal vein and the proper hepatic artery.

The hepatic artery itself arises from the ciliac trunk from the

common hepatic artery and brings the oxygenated blood to the hepatic tissues

while the portal vein collects deoxygenated blood from the abdominal contents and filters it, eliminating all the bad things and toxins and processes the nutrients that collects during absorption from the entire GI Tract.

Now you might be wondering why we're going into this cute little sort of review

about liver anatomy and blood supply. Well it turns out that complex vascular

supply and all the things the liver has to do from metabolic standpoint actually make it very vulnerable

to circulatory disturbances and those individual disturbances then can present as individual

liver diseases.

So I'm Dr. Nikakeets Son Paul, your friendly

neighbor internist and gastrantroologist, and welcome to this

week's podcast. We're going to talk about vascular conditions of the liver.

These are going to be ischemic hepatitis and hepatic infarction. Now our first topic is ischemic hepatitis, but many of you've heard of it called

shock liver, but shock liver is a bit of a misnomer because you can actually

have ischemic hepatitis in the absence of any type of shock,

whether that be cardiogenic or septic shock. And so the term that we really prefer is a schemic

hepatitis. Practically in the past it used to be
