Digestive System

1.The answer is your bones because it contains calcium.

2.The correct answer is hair and nails, because they're all made of ceratine

This test, whether performed for basal gastric acid secretion, gastric acid stimulation, or both, requires the passage of a lubricated rubber tube, either by mouth or through the nasal passage, while the patient is in a sitting or.

After macromolecules are broken down in the digestive process, their constituent molecules are absorbed into the bloodstream and used by the body for various functions. Carbohydrates are broken down into glucose for energy, proteins are broken down into amino acids for building and repairing tissues, and lipids are broken down into fatty acids for energy storage and cell membrane synthesis.

No, stomach acid is not an enzyme. Stomach acid primarily consists of hydrochloric acid and helps to break down food and kill bacteria in the stomach. Enzymes are proteins that facilitate chemical reactions in the body, while stomach acid aids in digestion by creating an optimal environment for enzymes to work.

Yes, the pharynx is part of the gastrointestinal tract. It is located at the back of the throat and serves as a passage for food and liquids to move from the mouth to the esophagus.

The body might use reducing agents, such as glutathione or NADH, to regenerate vitamin C that was lost in a cooked vegetable. These compounds have the ability to convert the oxidized form of vitamin C (dehydroascorbic acid) back to its active reduced form (ascorbic acid).

Milk of magnesia (magnesium hydroxide) is most commonly found as a liquid. The magnesium in the liquid can both neutralize excess stomach acid and, if taken in slightly larger doses, act as a saline laxative. This means that the magnesium works to pull salt or a saline solution from the blood into the intestines, therefore increasing the amount of water in the intestines and causing a laxative action. Milk of magnesia is generally considered to be one of the more gentle laxatives, as opposed to stimulant laxatives such as Dulcolax.

Bile salts produced by the liver help emulsify lipids, breaking them down into smaller particles that are more easily digested by enzymes. Lipase enzymes then work to break down the emulsified lipids into fatty acids and glycerol that can be absorbed by the body. Additionally, the presence of bile and lipase enzymes are important for the absorption of fat-soluble vitamins.

Goblet cells are the cells that produce mucus in the large intestine. These cells are specialized to secrete mucins, which help protect the intestinal lining and provide lubrication for the passage of stool.

The esophagus does not produce any enzymes. Even so, sometimes digestive enzymes produced in the stomach can make their way into the esophagus due to a hernia or a condition called gastroesophagic reflux.

A single starch molecule contents few thousands glucose monomers in single molecule.

Fatty acids are broken down through a process called beta-oxidation, which occurs in the mitochondria. During beta-oxidation, fatty acids are converted into acetyl-CoA, which can then enter the citric acid cycle for energy production.

The organelle that contains digestive enzymes used to recycle unwanted material in the cell is the lysosome. Lysosomes break down biomolecules and cellular waste through a process called autophagy, which helps maintain cellular homeostasis by removing damaged organelles and foreign particles.

The biological toxin you are referring to is likely a chemotherapeutic agent such as methotrexate. This drug targets rapidly dividing cells, including those in the bone marrow, gastrointestinal tract, and skin, leading to side effects such as oral and skin ulcerations, as well as gastrointestinal bleeding. By inhibiting cell proliferation, these toxins can effectively target cancer cells but also affect normal rapidly dividing cells.

Gravy is a protein based liquid and so the enzyme that breaks it down is protease, this is the same case as blood, egg or sweat.

Fatty acids and glycerol

The digestive enzymes in Hydra are produced in their cells, specifically in the gastrodermis, which lines the inner cavity of the body column. These enzymes help break down food particles that are ingested by Hydra for absorption and nutrient acquisition.

Germs in food are killed in the stomach due to the highly acidic environment. The stomach has a low pH level, typically around 1.5-3.5, which helps to kill off harmful bacteria and pathogens that may be present in the food we consume. Additionally, enzymes in the stomach also aid in breaking down the food and further reducing the risk of infection.

Lipids are broken down by the enzyme Lipase.

Alcohol and aspirin are the only two substances that can be absorbed directly across the stomach's mucosal epithelium without needing to enter the bloodstream through the small intestine. This is because these substances are lipid-soluble and can pass through the cell membranes of the stomach lining.

Small substances produced when proteins are digested are called amino acids. Amino acids are the building blocks of proteins and are absorbed by the body to use in various biological functions.

The enzyme responsible for breaking down bananas is called amylase. Amylase helps to break down the complex carbohydrates in bananas into simpler sugars like glucose, which can then be absorbed and used by the body for energy.

It's called saliva and the enzyme is call amylase or ptyalin.

Goldfish typically take about 24 to 36 hours to digest their food. It can vary depending on factors such as the size of the food particles and the temperature of the water. Overfeeding can lead to digestive issues in goldfish, so it's important to feed them in moderation.

Your mouth is a fertile home for millions of bacteria. Your brain tells your mouth to prepare for the arrival of food by secreting saliva, which is why your mouth waters when you see, smell, or even think about food. Saliva contains the enzyme amylase, which begins the digestion of starchy foods, such as potatoes and rice, and it moistens and lubricates food to help swallowing. Saliva also contains antimicrobial substances that inhibit the growth of pathogenic bacteria. But Streptococcus mutans thrives in your mouth and can easily bypass these defenses. It also loves sugar, and uses it to form a film, or plaque, on the surfaces of teeth. Bacteria thriving within these plaques turn sugar into acid, which then creates cavities in your teeth. However, large numbers of S.mutans suppresses the growth of another bacterium found in the mouth, Streptococcus pneumoniae, which can cause pneumonia and meningitis. By restricting the numbers of S.pneumoniae, S.mutansdecreases the risk of these serious diseases developing, so it's more important to keep sugar and refined carbohydrates out of your mouth than it is to try to eliminate all the bacteria.
