Respiratory System

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

nostrils, nasal cavity, trachea, bronchioles, and lungs.

I am not a doctor so I can't give medical advice.

The cancer can change the tissue. It can impair the airways by decreases the size of the airways or it could interfere with gas exchange through the air sacs in the lung. A person breaths by inspiring oxygen and exhaling CO2. Anything that interferes with that gas exchange makes it more difficult to breath. The degree of interference and the placement of the interference affects how difficult it is to breath. The problem starts when get a tumor. A biopsy is advised to determine what type of cancer it is and if it benign or malignant. If malignant the concern comes about isolating it and removing it if possibly. People can have the tumor to a lobe to a section of the right or left lung when if in this case should be removed. Many cancers are progressive and increase in size with time and that further interferes with the ability to breath. Having worked with lung cancer patients and seeing them die is a dreadful and sad experience. Imagine a world of difficulty breathing which is always ever present.

A good way to know how it feels to be short of breath is to remember the times after you have just run a distance and you feel out of breath. Imagine having that feeling all of the time probably to a lesser degree though. Diagnosing the Cancer early helps in preventing the spread and gives the person a better chance of surviving.

If I found out or suspected I had cancer I would see a doctor ASAP which would give me a better chance of surviving the disease and having a more normal life but this depends when the disease is caught, the type of the cancer, and whether is was spread from somewhere else. Remember I am not a doctor so I can't give medical advice.

the respirotry system functions is to deliever the oxygen into the body which is helpfull in metabolism as oxygen act as electron transporter in ETC and is help in many reactions occur inside the cells of the body.

Excretory system gets rid of waste. Respiratory system supplies blood cells with oxygen.

Amphibians are special animals In that they were the first tetrapods to develop lungs (in adults). Amphibians don't have nares, but instead breathe through their skin. This is do to capullaries placed closely to the outside of the skin, or epidermis.

Mucus is secreted in the respiratory system to moisten the incoming air and to trap dust particles. Ultimately, mucus can eliminate dust and harmful bacteria from the body.

Some organs that work in the respiratory system (such as the nose) are also lined with cilia, which are hair-like substances that push out large dust particles.

What would happen if you didn't have your lungs? You wouldn't be able to breathe. If you can't breathe you will die. The lungs are part of the respitory system. The respitory system allows your body to exchange oxygen. It allows you to inhale (breath IN) and exhale (breathe OUT). Without the respitory system you'd die! YOU NEED IT!

In order (the path of air) ; The nose. The Pharynxa.k.a the throat. the trachea. the bronchi. and the lungs. The respiratory system is rather simple: a breath starts out when a person clenches their diaphragm, creating a vacuum that the air is drawn into. The air enters in the trachea, or windpipe, going through one of the two bronchial tubes, which branch into smaller bronchioles. The bronchioles end in small sacs called alveoli, which have capillaries in them. The carbon dioxide in the blood in the capillaries is then exchanged for the oxygen in the air by diffusion. When that is done, the now oxygenated blood travels all over the body, supplying oxygen where it is needed. Then, the diaphragm relaxes, and the carbon dioxide rushes out of the alveoli, through the bronchioles and the the bronchial tubes, and out of the trachea, and out of the body through the nose or mouth. Then, it is done, and the diaphragm clenches...

Because anaerobic respiration releases less energy than aerobic respiration.

People value life more when they realize they are not immortal.

Pneumonia is a respiratory condition in which there is infection of the lung. Upper respiratory tract infections are the illnesses caused by an acute infection which involves the upper respiratory tract: nose, sinuses, pharynx or larynx. An example would be the common cold.

Diffusion ;)

This is the process of respiration. It involves bringing in air from outside the body into the lungs. When we breathe in, the size of our chest increases.This happens because when air enters, the lungs expand and the ribs move outwards. Simultaneously, the diaphragm contracts and becomes flat. Thus, the size of our chest increases.
