Explain the mechanics of breathing. Include the role of intercostal muscles, diaphragm, and air pressure.

Answers

Answer 1

When naturally occurring, inspiration and expiration occur with contraction and relaxation of the diaphragm and intercostal muscles. On inspiration, the diaphragm contracts and lowers and the ribs contract and rise. This enlarges the rib cage, lowers internal pressure, and forces air into the lungs.

What Respiratory Mechanics?

The basic function of the respiratory system is to supply the organism with oxygen (O2) and to remove from it the gaseous product of cellular metabolism, that is, carbon dioxide (CO2). In unicellular organisms, gas exchange occurs directly between the cell and the surrounding medium through simple diffusion. In multicellular organisms, diffusion between the external environment and the interior of the cell mass occurs slowly, due to the distance to be covered by the gases.

With this information, we can conclude that When naturally occurring, inspiration and expiration occur with contraction and relaxation of the diaphragm and intercostal muscles. On inspiration, the diaphragm contracts and lowers and the ribs contract and rise. This enlarges the rib cage, lowers internal pressure, and forces air into the lungs.

The availability heuristic, often referred to as the availability bias, is a mental shortcut that depends on the first instances that come to a person's mind when evaluating a certain subject, idea, approach, or choice.

According to the availability heuristic, something must be essential if it can be remembered, or at least more important than alternatives that are more difficult to remember. The availability heuristic thus leads to people's propensity to heavily weigh their judgments toward more recent information, biasing fresh opinions in favor of that most recent news.

Development in Nepal is not uniform in different places. This means that being a tourism-oriented country, the most visited areas have greater development, what can be done for balanced regional development in Nepal is the correct distribution of income.

What is nepal?

Nepal is a poor nation with an economy based on agriculture and tourism. About 90% of the inhabitants work in agriculture, mainly in rice cultivation. The Indian influence, increasingly strong, in a short time gave rise to a strongly Indianized caste society and a powerful Buddhist center. Tourism has grown since democracy was restored in 1990, helped by the lifting of restrictions on foreigners in 18 areas in the northwest of the country. Lumbini - the birthplace of Buddha - and the lake town of Pokhara are among the main attractions.

Answers

Medical abbreviations are still commonly used in healthcare settings because using abbreviations saves time and space while writing medical records of patients, as well as they allow some privacy because mostly only professionals can understand these abbreviations.

These abbreviations are useful but they have their cons too, as they can create confusion because one abbreviation can have more than one contradictory meaning. which can lead to miscommunication of information. This can be dangerous in healthcare settings.

To increase the safety of using medical abbreviations a national or standard list of abbreviations should be created by the healthcare and government organizations to ensure that one abbreviation has only one meaning and to avoid confusion.

Another thing can be to limit the unnecessary usage of abbreviations because it can lead to miscommunication.

______________ chemically alter the make-up of nutrients, changing them into a form that can be readily used by cells

Answers

Answer:

Enzymes

Explanation:

An example of a biological catalyst is an enzyme. A catalyst is a substance that quickens a chemical process. In order to cause a bond to form or break, an enzyme must first attach to its target, also known as a substrate. Although the enzyme does not really take part in the chemical reaction, it helps to make it happen and increases the likelihood that it will. Alcohol dehydrogenase is a prime illustration of this. This enzyme is in charge of cleansing your blood of alcohol. It functions by bringing the molecules of ethanol and NAD+ very close together and holding them there long enough for the ethanol molecule to transfer a hydrogen atom to NAD+, resulting in the formation of acetaldehyde and NADH. The byproducts of the conversion of acetaldehyde to acetyl CoA, which is utilized as energy, are expelled. There are several mechanisms by which enzymes can be controlled in the body, including pH and substrate concentration. You don't want an enzyme to be active if it isn't being used since it can start catalyzing things that you don't want it to. For instance, the stomach enzyme pepsin, which breaks down proteins, only works when the pH is below 4. (for reference, blood pH is 7.3 while stomach pH is around 2). This is extremely beneficial to your health since pepsin won't start working until it is secreted into the stomach, where it belongs. Your cells' proteins would be degraded if pepsin were present, which would be extremely harmful. Another method for controlling enzyme activity is substrate concentration. The rate of a reaction will decrease if you give an enzyme less substrate to work with (less substrate available for the enzyme).

Intensity: A person has to begin with lighter weights and work their way up to the highest weight that can be lifted for the whole set.

Time : A person has to perform 8 to 15 repetitions of each strength-training exercise, which equals one set. 1 to 2 sets per muscle group (biceps, triceps, chest, back, quads, hamstrings, etc.) have to be performed.
