Respiratory System

When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs.

The respiratory system starts at the nose (and mouth) and ends at the alveoli in the lungs

The average healthy individual is stimulated to breath by the carbonic drive, or increased levels of carbon dioxide. When our paco2 levels increase our internal ph levels decrease causing us to become acidotic. Therefore, we breathe more in an attempt to blow of the excess paco2 subsequently increasing our ph and regaining homeostasis.

Most of the adrenaline in the human body is released by the adrenal gland. The adrenal gland is a part of the sympathetic nervous system, a branch of the nervous system that regulates the classic stress response and has numerous roles in other normal body functions. Adrenaline, called epinephrine by scientists in the US, is the major hormone released during the classic stress response (also called the fight-or-flight response), which is why it is often considered a fight-or-flight hormone. It has several actions in the body that make it good at this job: it dilates the pupils to increase the amount of light that enters the eyes, it causes sweating to help dissipate heat, it increases blood flow to the muscles, it increases the heart rate and force of contraction, and it makes glucose available in the blood for use by other organs.

They are known as cilia.

1. The diaphragm in bell jar model is pulled down during inhalation, whereas in actual respiration, the diaphragm is flattened.
2. The wall of the bell jar is rigid, whereas the thoracic wall is flexible and changes during breathing.
3. the bell jar cavity is filled with air, whereas the thoracic wall is filled with body fluid.

this gonna be asewmo

healthy foods is always the answer. i am hypoglycemic and all i do to never feel shaky is eat very healthy whole grains, fruits, vegitables, meats. MILK!

there is a specific group of cells found in the medula (part of the brain stem) which regulate the rhythm of breathing, hence the name (of this cellular formation) the Medulary Rhythmicity Center.

Yes, because the nostril's hairs filter the air before it can go into the esophagus. The hairs capture the mucus and keep it so that the lungs dont get full of mucus.

There is little evidence of significant adverse effects on respiratory health associated with bauxite mining.

well, the effect is very basically, scaring of the lungs due to the amount of coughing. in the gas exchange, normally less oxygen is absorbed because of the carbon dioxide from smoking, which normally is the cause of chronic bronchitis. emphysema is just where a person gets loads and loads of infections which makes the person ill, cough alot, get scares on the lungs which weaken them meaning alveoli might not absorb as much oxygen into the blood stream or as much carbon dioxide out of the blood. THIS IS A VERY BASIC TASTE OF THIS, for more, just type this into google "define: (the name of the disease goes here)"

Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound.[1] This is in contrast to cellular respiration, where electrons are donated to an exogenous electron acceptor, such as oxygen, via an electron transport chain. Fermentation does not necessarily have to be carried out in an anaerobic environment, however. For example, even in the presence of abundant oxygen, yeast cells greatly prefer fermentation to oxidative phosphorylation, as long as sugars are readily available for consumption.[2] Cellular respiration is the set of the metabolic reactions and processes that take place in organisms' cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another.

the major veins are the nose, lungs, espogus, idk how to spell it. and the diapram.

The respiratory system's role in energy metabolism lies is to allow the exchange of gases to take place in the lungs and tissue cells. Oxygen is needed for certain metabolic reactions to occur and for the production of energy.

Your question is somewhat vague. If you are underwater, you pass out because of lack of oxygen and your organs begin to die, especially the brain. It is miraculous when someone has been underwater without oxygen for more than even a few minutes and survives without brain damage.

If you are talking about holding your breath, while it is difficult to hold one's breath until they pass out it is not impossible; this is your body shutting down all nonessential systems in a last ditch effort to get you breathing again---while your will may be strong enough to get you to pass out, once you are unconscious you will breathe unless your airway is blocked.

Respiration is not essential for life. Many forms of bacteria do not undergo cellular respiration and are still considered 'alive'. Respiration, more specificially cellular respiration, is just one of many ways (although one of the more energetically efficient ways) for a cell to produce energy.

Human cells are capable of producing energy in one of two ways, depending on the condition the cells are placed in. The most common of the two ways is through cellular respiration. This occurs when there is sufficient oxygen being carried to the cells via the blood. The second occurs when the body's cells do not have enough oxygen to support cellular respiration. This is commonly experienced during heavy workouts. When the body's cells don't have the needed oxygen to undergo cellular respiration, the cells revert to a form of energy creation called 'fermentation,' which DOES NOT require oxygen. Fermentation causes the build-up of lactic acid in muscle cells, which leaves that sore feeling in your muscles after a workout.

The respiratory system's main job is to aid in the exchange of oxygen and carbon dioxide between blood and air (breathing) and blood and tissue fluid; oxygen is also used in cellular metabolism.

It also aids in the production of speech and other noises, makes sense of smell possible, helps control the pH of bodily fluids, helps in the regulation of blood pressure, breathing creates a pressure gradient that helps in the flow of venous and lymph blood, and aids in childbirth and expelling bodily wastes through holding of the breath.

The nose.

The nose has three levels of concha. These layers are there to increase the surface area of the nose. The increased surface area gives the air more surface to hit on the way in, and therefore warms it up. The hairs on the inside of the nose are for filtering the air before it gets to the lungs.

how does the respiratory system contribute to your overall health

Yes it controls the breathing. cells that are in the automonic nervous system from the Medulla oblongata send messages to the diaphragm to contract, letting/forcing you breathe. cells in its breathing center monitor the amout of carbon dioxide in your blood. when the level gets low they tell you to beathe. The breathing proccess is mostly volantary (meaning you control it) but in some cases when the carbon dioxide level is dangerously low, your body takes over and forces you to beathe.

True

It is absobed into the small intestine:)

Nose>>>pharynx>>>larynx >>>trachea >>>bronchus >>>bronchiole >>>alveolus

Hemoglobin is an oxygen-carrying pigment in human blood. It includes iron in its makeup.

i thank the lungs or something dont listen to me because i do not know
