GENERAL HISTOLOGY

Detailed explanation-1: -The liver also cleans blood that has just been enriched with vitamins and minerals during digestion. After you’ve eaten something, the vitamins, minerals, and other nutrients from the food pass from the intestine into the blood.

Detailed explanation-2: -All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

Detailed explanation-3: -Anatomy of the liver The liver has many functions. There are 2 distinct sources that supply blood to the liver: Oxygenated blood flows into the liver through the hepatic artery. Nutrient-rich blood flows into the liver from the intestines through the hepatic portal vein.

Detailed explanation-4: -Stomach: An organ with strong muscular walls, the stomach holds the food and mixes it with acid and enzymes that continue to break the food down into a liquid or paste.

Detailed explanation-5: -No digestion occurs in the esophagus. After passage through the esophagus, the bolus will enter the stomach and undergo mechanical and chemical digestion. Mechanical digestion in the stomach occurs via peristaltic contractions of the smooth muscle from the fundus towards the contracted pylorus, termed propulsion.
