And this filtered blood that enters Araboman's capsule is known as the glomerulus filtrate, or simply Arifiltrate. So from now on, when we refer to the blood found inside this region, that is Arifiltra, but the blood found here is known as simply the blood plasma or our blood. Now, this portion of the nephron is known as the Proximal convoluted tubule. And as our blood plasma travels, as our filter travels across the proximal convoluted tubule, reabsorption as well as secretion begin to take place. So certain molecules such as, for example, amino acids, sodium ions, as well as other things such as our glucose molecules, are reabsorbed from the filtrate and back into our blood plasma. But other waste products such as, for example, hydrogen ions and creatine molecules, are secreted from the blood plasma and into the lumen of the proximal convolute.
