Digestive System

It is the saliva produced by the mouth which starts to break down the food. The technical term for the enzyme is salivary amylase.

Lysosomes are the organelles responsible for carrying digestive enzymes that can break down foreign material such as bacteria. They help to maintain cell health by removing waste and harmful substances.

Lactose, a sugar found in dairy products, cannot be digested properly if the body does not produce enough lactase enzyme. This can lead to digestive issues such as bloating, gas, and diarrhea in individuals who are lactose intolerant.

Absorption in biology refers to the process by which substances, such as nutrients and water, are taken up by cells and tissues in the body. This process typically occurs in the digestive system, where nutrients from food are absorbed into the bloodstream for use by the body's cells.

The epithelial lining of the gastrointestinal tract is called the mucosa. It is composed of specialized cells that help with absorption, secretion, and protection within the digestive system.

Eating uranium is a bad idea, as you probably guessed. Fortunately for people, most uranium that is ingested will pass relatively quickly through the digestive tract, but some may be absorbed. Absorbed uranium poses a hazard, and the amount of uranium ingested would have to be quantified to make an assessment. Breathing uranium, which is a separate issue, is much more hazardous.

There will be variations in the amounts of uranium absorbed by the body that will depend on whether the ingested material is uranium metal or whether it is a compound of this actinide. Organic compounds will be absorbed more readily than, say, uranium oxide. Further, the uranium that gets uptaken may be deposited in the bones, the liver or other places.

The long term effect of absorbed uranium is that is may be in someone for a while and present a radiation hazard. We know that uranium is radioactive, though weakly. If uranium is deposited in tissue, it may stay there for a while. Radioactive decay will leave decay products, which are also radioactive, stuck within the affected tissue. Anyone who "takes in" uranium may be in store for some body scans to assess damage and what risks the future may hold. It is a challenge to quantify the amount of uranium that a person may have within him, and medical assessment will depend on a good workup.

An antacid solution used to neutralize excess stomach acid would have a higher pH than stomach acid, typically closer to 7 or slightly above to effectively neutralize the acid. This means that the antacid solution would be less acidic and more basic compared to stomach acid.

Yes, stomach acid can dissolve organic materials like fingernails due to its high acidity (pH 1.5-3.5). The time it would take for stomach acid to dissolve fingernails would vary depending on factors such as the strength of the acid, the size of the nail piece, and the individual's digestive system, but it could potentially happen within a few hours to a couple of days.

A fat is an ester of three 'fatty acids' and glycerol.

Digestive fluids contain various catalysts such as enzymes, which help break down large molecules into smaller ones for absorption and utilization by the body. Some common enzymes found in digestive fluids include amylase, protease, and lipase, which assist in the digestion of carbohydrates, proteins, and fats, respectively.

The loops of the small intestine, specifically the jejunum and ileum, are anchored to the posterior wall of the abdominal cavity by the mesentery. This double-layered fold of peritoneum provides support and allows for mobility of the intestines during digestion and absorption of nutrients.

The cells found in the gastric glands include mucous cells, parietal cells, chief cells, and enteroendocrine cells. These cells secrete mucus, hydrochloric acid, pepsinogen, and various hormones to help with digestion and stomach function.

No, bile does not neutralize stomach acid. Bile is produced by the liver and stored in the gallbladder, where it helps to emulsify fats in the small intestine. Stomach acid is mainly neutralized by bicarbonate secreted by the pancreas in the small intestine.

The main function of the digestive system is to take the food we eat and take out the minerals and vitamins that then get carried to the muscles in your body by the blood (circulatory system). The leftovers gets carried to your kidneys (who filter them) and anything that the digestive system didn't get gets sent back to the organs and muscles by the blood stream.

Any form of digestion is a chemical reaction. It begins when you chew with the saliva in your mouth and continues all the way down to your intestine. Bread, which contains mostly starches, is converted into sugars, which in turn provide your body with energy. This is why runners and other athletes sometimes eat pasta the night before they have an event.

Ameoba extends pseudopodia around the food particle until they join, enclosing the particle in a membrane-bound vesicle. A lysosome merges with the new food vacuole, dumping its enzymes in to digest the food. The products of digestion are then absorbed through the membrane.

No, digestive enzymes are not necessary for mechanical digestion. Mechanical digestion involves the physical breakdown of food into smaller pieces through actions like chewing and churning, while digestive enzymes are responsible for breaking down food chemically into nutrients that can be absorbed by the body during the process of chemical digestion.

Digestive enzymes actually help speed up the digestion process by breaking down proteins, carbohydrates, and fats into smaller molecules that can be absorbed by the body more easily. They work in coordination with the body's natural digestive processes to enhance overall digestion and absorption of nutrients.

Digestive juices do contain water, but the exact amount can vary. For example, saliva is about 99% water, while gastric juice is composed of around 98% water. In general, water plays a crucial role in helping to break down food and facilitate the digestive process.

The five main organs in the digestive system are the mouth, esophagus, stomach, small intestine, and large intestine. These organs work together to break down food, absorb nutrients, and eliminate waste from the body.

Some viruses can survive passage through the gastrointestinal tract due to their ability to resist stomach acid and bile salts. However, many viruses are not able to survive this harsh environment and are inactivated before they can infect cells in the intestines.

pepsin is an enzyme in the stomach specific to proteins sucrose is a di-sacaride ie sugar not a protein common this is easy stuff think about it each substrate has a specific enzyme this is extremely basic stuff don't consider a career in biochemistry buddy

Pepsin works best at 37 C because that is it's optimal temperature. The temperature at which it works best. Every enzyme has one which is based on the molecular geometry and binding of the protein...

A physical change that occurs during digestion is the mechanical breakdown of food into smaller pieces through chewing and churning in the stomach. A chemical change that takes place is the breakdown of macromolecules like proteins, carbohydrates, and fats into simpler molecules like amino acids, glucose, and fatty acids through the action of enzymes.

Food is chewed and moistened in the mouth, where it mixes with saliva to begin the process of breaking down carbohydrates. The teeth help mechanically break down food into smaller pieces, while enzymes in the saliva start to chemically digest starches.
