What irritators are used to obtain a stimulated portion of gastric juice in gastric fractional intubation?

Answers

Gastric acid, gastric juice, or stomach acid, is a digestive fluid formed within the stomach lining. With a pH between 1 and 3, gastric acid plays a key role in digestion of proteins by activating digestive enzymes, which together break down the long chains of amino acids of proteins. Gastric acid is regulated in feedback systems to increase production when needed, such as after a meal. Other cells in the stomach produce bicarbonate, a base, to buffer the fluid, ensuring a regulated pH. These cells also produce mucus – a viscous barrier to prevent gastric acid from damaging the stomach. The pancreas further produces large amounts of bicarbonate and secretes bicarbonate through the pancreatic duct to the duodenum to neutralize gastric acid passing into the digestive tract.

The active components of gastric acid are protons and chloride. Often simplistically described as hydrochloric acid, these species are produced by parietal cells in the gastric glands in the stomach. The secretion is a complex and relatively energetically expensive process. Parietal cells contain an extensive secretory network (called canaliculi) from which the "hydrochloric acid" is secreted into the lumen of the stomach. The pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, a level maintained by the proton pump H+/K+ ATPase.[1] The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline tide.

The highly acidic environment in the stomach lumen degrades proteins, e.g. food. Peptide bonds, which comprise proteins, are labilized. The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). The low pH activates pepsinogen into the enzyme pepsin, which then aids digestion by breaking the amino acid bonds, a process called proteolysis. In addition, many microorganisms are inhibited or destroyed in an acidic environment, preventing infection or sickness.

How can you show joy of effort, respect
for others and fair play when you are
playing sports? Give two examples for
each.​

Answers

Fair play, which is an essential and central part of successful involvement, promotion and development in both sport and life, can teach people tolerance and respect for others. It allows them to integrate into society and create a sense of teamwork.

Setting the rules and getting everyone to agree on the rules is the first step to avoiding arguments when the competition has begun. Sometimes it's even fun to make up your own rules as you go along, but make sure that everyone is clear on what the rule changes are. That's the way to fair play.

Obeying rules of the game or sport shows the joy of effort, respect  for others and fair play.

We can show joy of effort, respect  for others and fair play when we are  playing sports through obeying the rules of the sport and don't taking failure personal or don't be aggressive. If we obey all the rules of the sport then it means that you show joy of effort, respect  for others and fair play.

Taking a sport as a sport not personal and avoiding aggressive behaviour also a form of joy of effort, respect  for others and fair play so we can conclude that obeying rules of the game or sport shows the joy of effort, respect  for others and fair play.

what a personal lifestyle choice involves​

Answers

It is a person's choices and preferences outside of work that define personal life, including one's choice of hobbies, cultural interests, manner of dress, mate, friends, and so on. In particular, what activities one engages in during leisure-time defines a person's personal life.

Apart from hunter-gatherers, most pre-modern peoples' time was limited by the need to meet necessities such as food and shelter through subsistence farming; leisure time was scarce. People identified with their social role in their community and engaged in activities based on necessity rather than on personal choice. The modern conception of "personal life" is an offshoot of modern Western society. Modern people tend to distinguish their work activities from their personal life and may seek work–life balance. It is a person's choices and preferences outside of work that define personal life, including one's choice of hobbies, cultural interests, manner of dress, mate, friends, and so on.

name different types of medicine that you can make in the woods

Answer:

Explanation:

Natural Aspirin and Acne Medication

Willow bark, also known as “nature's aspirin,” contains a precursor to aspirin, which essentially provides the same benefits as the tablet. Early incarnations of aspirin were made by boiling the bark of the white willow tree.

Within the plant kingdom, trees make a substantial contribution to this figure and many species are used in traditional and modern medicine. Medicine from trees, extracted from the wood, bark, roots, leaves, flowers, fruits or seeds is fundamental to the well-being of millions of people.

Tulsi,pudina, curry leaves and aloe-vera plants are known for their medicinal uses but the coutry also home to big trees that holds special significance in Ayurveda of India. The list of famous medicinal trees in India also includes bahera tree, Albizia lebbeck, Maulsari, Indian Mahogany and Eucalyptus.

Wood contains thousands of compounds, though only a fraction of them are known to us today. Many of the compounds are linked to the tree’s defence mechanisms. They protect the tree against fungi and many other pathogens. Scientists are now investigating whether these compounds could also benefit people. For example, spruce resin protects damaged bark surface from fungal spores, and it has also been used to treat human wounds throughout the ages. Now, the efficacy of resin in wound treatment has been verified in medical research.

Xylitol is also known as birch sugar. The name reveals the origin and purpose of the compound. German and French scientists discovered xylitol as a chemical compound back in the 1890s, but it wasn’t until the 1970s when its benefits in dental health were discovered and verified by scientists in Finland.

In the early 1970s, scientists at the University of Turku discovered that xylitol prevents cavities. Some years later, researchers at the University of Oulu also found it to reduce ear infections in children. Xylitol is manufactured from birch hemicelluloses.

Antibodies for high cholesterol and cardiovascular diseases have also been discovered in wood. Pine compounds can be used to make plant sterols and stanols, which are added to margarines and yogurt products. When consumed regularly, these products can help to reduce cholesterol.

Betulin, a product of birch bark, also reduces cholesterol. Betulin gives birch bark its white colour, and it has strong antibacterial properties. The use of betulin in medicines has been researched in Finland as well as other countries including China. The betulin molecule is so large that it cannot penetrate the cell wall. Medical researchers are trying to use betulin to protect the cell surface against diseases. Betulin has been found to limit the activity of the HIV virus. The possibility of using it as an HIV drug is currently being studied.

The part of the tree branch which is inside the stem is called softwood knot. A compound called HMR lignan is harvested from the knots of spruces. It can help to prevent cancer and cardiovascular diseases. Another Finnish invention, the HMR lignan is also being studied for possible application as a HIV drug, just like betulin.

All compounds extracted from trees can be harvested at pulp plants during pulp manufacture. In future biorefineries, wood will have increasingly more diverse uses as an ingredient in a range of different products. The study and discovery of new compounds with health benefits from trees and other forest products are ongoing. In addition to the pharmaceutical industry, the cosmetics industry is also interested in products originating from wood.
