    Hello all; I'm new to the forums, so I hope this is the right place to be posting this question! In my biology class, we recently went over the different filtration sites of the kidneys. However, we were told that most larger molecules (red blood cells) are simply not put through this process because of their importance to our health. For a laboratory paper, however, we are being asked to map out a path that a large organic molecule of > 10000 daltons would take through the kidneys. How is this possible? I have looked for information elsewhere on the web, but I haven't been too successful. Any help would be greatly appreciated!

    not exactly sure what you are asking here. If a red blood cell passed into the kidney tubule it would pass out through the collecting ducts, through the ureter to the bladder and leave the body via the urethra. What different filtration sites are you talking about? there is only the glomerulus/bowmen's capsule, are you referring to reabsorption, secretion, and post-secretary reabsorption?

    who told you that? sodium is important to your health but it is filtered.

    if larger molecules and cells passed through then it would not be a filtration system it would just be an open tube
