Abdomen Sonography: Liver Perfusion and Function - Video Lesson

Hey everyone. Welcome back to today's lesson on the vascular perfusion and physiology of the liver. In this lesson, we'll review the liver's primary functions, metabolic, synthetic, and detoxification, and touch on common lab tests used to assess liver function. We'll also look at the blood supply to the liver, including the hepatic artery and portal vein, along with the hepatic veins. We'll wrap up by identifying normal Doppler waveforms of the portal venous system. Let's get started. The liver has many functions, but let's focus on the major ones that sonographers are required to know. First up, the liver is a metabolic powerhouse. It metabolizes carbohydrates, fats, amino acids, vitamins, and proteins, which allows it to produce key substances like bile and urea. Bile is stored in the gallbladder and plays a vital role in fat digestion. Urea is formed when the liver breaks down toxic
