Digestive System

Yes, villi are finger-like projections found in the lining of the small intestine, which is part of the gastrointestinal tract. Villi increase the surface area of the intestine, helping to improve nutrient absorption.

A perch has a complete digestive tract, which includes a mouth, esophagus, stomach, intestine, and anus. This structure allows for more efficient digestion and nutrient absorption compared to organisms with a gastrovascular cavity.

Digesting" a solid material in chemistry means to contact the material with a liquid until at least part of the original material is dissolved in the digesting liquid. Heating is often applied to speed the reaction. Thus, biological digestion in humans is a special case of chemical digestion, when solid food particles are mixed with the natural acid solution in the stomach and changed to water soluble materials.

Proteins that carry out enzymatic activity are known as enzymes. Enzymes can catalyze the conversion of substrate into the product. In digestion hydrolytic enzymes such as proteases, lipases, glycosidases such as amylase digest proteins, lipases, and carbohydrates respectively.

Technically, it would be to "fecate." That means to accumulate feces. Defecate means to remove fecal matter from the body.

Inflammation occurs in the body as a natural response to injury or infection. It is the body's way of protecting itself and initiating the healing process by sending immune cells and chemicals to the affected area. Chronic inflammation, however, can lead to various health issues.

Activated charcoal is commonly used to help relieve symptoms of gas, bloating, and diarrhea by binding to toxins and gas in the digestive tract. It may also be used in cases of drug overdose or poisoning to help prevent absorption of harmful substances in the body.

The mitochondria is the organelle responsible for generating energy through cellular respiration, which involves taking in oxygen and releasing carbon dioxide. This process is essential for the cell to "breathe" and produce ATP for various cellular functions.

Fiber is a nutrient that is not fully absorbed by the digestive system because humans lack the necessary enzymes to break it down completely. Instead, fiber passes through the digestive tract mostly intact, providing benefits like promoting healthy bowel movements and supporting gut health.

The caecum (also cecum) is a pouch-like structure at the beginning of the large intestine between the ileum and the colon. It is the structure to which the appendix is attached.

Yes, barfing is a physical change because it involves a change in state and appearance of food without altering its chemical composition. The food that is consumed undergoes physical changes as it comes back up from the stomach.

Protease enzymes, such as pepsin and trypsin, are responsible for breaking down proteins in food into smaller peptides and amino acids. These enzymes work in the stomach and small intestine to facilitate the digestion of proteins.

That condition is called as GERD or gastro-esophageal reflux disease. You have no anatomical spincture to prevent the back flow of stomach contents into esophagus. But then the physiological spincture is present to prevent such back flow. Some times this spincture fails and the contents of the stomach may come up. This happens during sleep, when you are in horizontal position and not awake to prevent the spill in the larynx. Such spill make you to get up, out of sleep suddenly and may cause laryngitis.

The stomach precedes the small intestine in the digestive system. After food is chewed in the mouth and mixed with saliva, it travels down the esophagus and enters the stomach where further digestion and breakdown of food occurs before passing on to the small intestine for absorption of nutrients.

This weakness and bulging of the respiratory diaphragm where the esophagus passes occurs more often in women than in men. It can cause abdominal pain, heartburn and sometimes chest pain that can be mistaken for a heart attack.

Protease enzymes, such as pepsin and trypsin, speed up the breakdown of proteins in food. These enzymes help break down the proteins into smaller peptides and amino acids, which can then be absorbed by the body for energy and building blocks.

The endogenous water in the gastrointestinal tract comes from secretions produced by the digestive system, such as saliva, gastric juices, pancreatic juices, and bile. This water is essential for the digestion and absorption of nutrients in the gut.

Do you mean Enzyme?

Enzymes are proteins that participate in cellular metabolic processes with the ability to enhance the rate of reaction between biomolecules. Some enzymes can even reverse a reaction from the direction it would normally take, by reducing the activation energy (Ea) to the extent that the reaction favours the reverse direction. Simlarly, enzymes can catalyze reactions that might not otherwise occur, by lowering the Ea to a more "affordable" level for the cell.

Enzymes can be isolated using various protein purification methods. The purity of an enzyme preparation is measured by determining it's specific activity

The enzymes in the saliva works fastest at optimum temperature (Body temperature) around 37 degrees Celsius.

Actually, that's not completely accurate. The higher the temperature, the faster the rate of any chemical reaction, and that's also true of the enzymes in the human body. Our body temperature is regulated right around 37 degrees centigrade (98.6 F), but your body temp can increase, and it does during hard exercise or when you're feverish. At those higher temperatures the enzymes will work more rapidly than they do at 37 degrees.

Now, why should that be the case? Why not operate always at optimum temperature?

Because as temperature increases, we eventually arrive at a point at which the enzymes begin to denature and stop working. When that happens, the individual dies, which is not a good thing. That's why your body's normal operating temperature is not the optimum temperature for your enzymes. If your body temperature was regulated at optimum temperature under relaxed conditions, when you began to exercise or when you got a fever, your enzymes would denature and you'd die. Regulating your body's temperature at a point 4 or 5 degrees below optimum represents an important safety factor.

As the bible states nobody is perfect but god forgives all sins such as lieing. On the other hand an average person lies more than one billion times every five years! So you do the math to what ever your question is.

The mouth is involved in both chemical and mechanical breakdown of food. Mechanical breakdown occurs through chewing and mixing with saliva, while chemical breakdown is initiated by enzymes in saliva that start breaking down carbohydrates.

Protein chains are broken down into amino acids by enzymes in the stomach and small intestine during the process of digestion. These enzymes break the bonds between amino acids, allowing them to be absorbed into the bloodstream.

There are two that begin to be digested in the mouth. Sugars by amylase and fats by lingual lipase.

All the digestive enzymes are made of protein, yet some of them are protein-digesting enzymes. If they were all dumped into the same "pot" the protein digesting enzymes would quickly destroy the other enzymes, and the whole process would grind to a halt. The body must separate protein digestion from other processes.
