1. After the surgical removal of the gallbladder, a person must be especially careful with the intake of fat. The gallbladder stores bile produced by the liver, which helps in the digestion of fats. Without the gallbladder, fat digestion may be compromised, leading to potential issues with fat absorption and digestion. 2. The organ responsible for the production of bile is the liver. Bile is produced by the liver and stored in the gallbladder. It plays a crucial role in emulsifying fats, aiding in their digestion and absorption in the small intestine. 3. Peristalsis is the wave of muscular contraction that moves food down the esophagus. This rhythmic movement helps propel food through the digestive system, allowing for the mechanical breakdown and absorption of nutrients along the way. 4. Molar teeth are designed for shearing and grinding. They play a key role in chewing and breaking down food into smaller particles, which facilitates further digestion and absorption in the digestive tract. 5. Choking can result from food stalled in the pharynx, obstructing the airway. It is essential to chew food thoroughly and swallow carefully to prevent choking incidents. 6. In humans, most of the chemical digestion and absorption occur in the small intestine. This is where enzymes break down food into smaller molecules that can be absorbed into the bloodstream through the intestinal wall. 7. Bile is stored and concentrated in the gallbladder. The gallbladder releases bile into the small intestine to aid in the digestion and absorption of fats. 8. The process of moving digested food through the villi into the bloodstream is known as absorption. Villi are small finger-like projections in the small intestine that increase the surface area for nutrient absorption into the blood circulation. 9. Undigested parts of food that were not absorbed pass into the large intestine where water is absorbed, and the remaining material forms feces, which is eventually eliminated from the body through the rectum and anus.
