All blood leaving the GI tract first goes to the liver through the hepatic portal vein for processing and detoxification before entering the general circulation.
Another name for the gut is the gastrointestinal tract (GI tract) or digestive system.
The walls of the GI tract are composed of four main layers of tissue: mucosa, submucosa, muscularis, and serosa. Each layer has a specific function that contributes to the digestive process.
Most of the GI tract is composed of simple columnar epithelium. This type of epithelium is well-suited for secretion and absorption processes due to the presence of microvilli, which increase the surface area available for these functions.
What's the name of a condition that develops after the acute phase of an illness or injury has ended
Yes. But plugging it doesn't make it anymore effective and/or stronger. The best route is orally so your GI tract can convert the majority of the drug into dextroamphetamine.
It gets into the blood which carries it to the brain.
No, a drug that is 100 percent absorbed from the gastrointestinal (GI) tract would not necessarily have 100 percent bioavailability. Bioavailability is affected by factors such as first-pass metabolism in the liver, which can reduce the amount of the drug that reaches the systemic circulation unchanged. Thus, even if a drug is fully absorbed, its bioavailability may be less than 100 percent.

It depends on the intrinsic properties of the drug and the route of administration. Oral drugs are often absorbed from the GI tract into the hepatic portal vein, undergo first pass, and then reach the systemic circulation. They can be biotransformed (metabolized) in the liver, kidneys or even lungs. Most drugs are excreted by the kidneys into the urine, but some are excreted into bile by the liver. Blood flow to particular organs, and the relative lipophilicity of the drug affect how it will behave in the body. It's metabolism is also key in figuring out how it will be excreted.
cefpodoxime proxetil is a prodrug that is de-esterified in the GI tract. It becomes cefpodoxime free acid which is the active metabolite.
It bypasses the GI tract, thereby decreasing the absorption time, allowing it to become therapeutic at a faster rate.
The stomach has the thickest walls and the strongest muscle in all the GI tract organs. : )
