Hi, everyone. Let's take a look at this practice problem together. Albumin is an important protein that is responsible for osmotic pressure balance in which organ is albumin synthesized. The answer options are a bones, B, pancreas, C, kidneys and D liver. So, recall that albumin is a plasma protein, meaning it is a protein in the blood. And as the question states, it's responsible for osmotic pressure balance. How does it do this? Well, Albumin has a large and globular shape, the size and shape of albumin makes it unable to cross the vascular walls. So, bean is stuck in the bloodstream and since it's a large protein in the bloodstream, it attracts water into the blood. And that is how that is how it maintains the osmotic pressure balance. So what organ synthesizes albumin? It's not bones, it's not the pancreas and it's not the kidneys, it's the liver. And in fact, the liver is responsible for synthesizing and releasing over 90% of the plasma proteins. So the correct answer is option D liver. All right, everyone. I hope you found this helpful and I'll see you soon for the next practice problem
