Respiratory System
The respiratory system includes the lungs and the airway. The questions in this category focus mainly on the anatomical and physiological processes associated with breathing.

How does the respiratory system affects exercise?
when we do exercise blood wants to more and more oxygen due to which we respire depth
First of all, you typically breathe deeper when exercising, so that brings more oxygen into your lungs which increases blood flow throughout the body. The increased oxygen helps the body rid itself of toxins. Secondly, it strengthens the muscles around the lungs and heart, making them work better.
How do you breathe when you are in a contortion position?
For starters, let's just keep in mind that any type of breathing is better than no breathing at all (often times when I works with students they have a habit of holding their breath) I would say that to take as normal a breath as you might take just walking down the street is optimal. Naturally breathing is harder when in a difficult position but you just have to focus on maintaining it throughout the entire exercise.

What happens to oxygen after gas exchange?
the oxygen is taken into your blood and transported around your body in your veins and arteries.

What is the role of internal receptors in breathing rate?
Internal receptors, or intereceptors measure the amount of carbon dioxide in the blood, and that information is relayed and processes by the medulla oblongatta, which is the respiratory center in the brain stem.
A hagfish has one nostril. It breathes by taking in water though its nostril and then expelling it through a series of spherical breathing pouches, each of which contains two gills.

What is the role of anaerobic respiration in living things?
Anaerobic respiration plays a major role in keeping us alive like when your running around and you feel out of breath anaerobic respiration takes over and give your body energy when your lungs cant
What two things happen to air inside the nose?
inside the nose, tiny hairs clean the air by catching dirt and other particles. the air also warms as it travels through the nose.
What the diaphragm is and how it aids in breathing?
It's a muscle located under lungs, responsible for creating a negative pressure when it contracts, thus creating a vacuum in the lungs which gets filled with air.
Can using oxygen to breathe make you go blind?
Yes. Elevated oxygen levels for too long can make you lose your vision. That's why premature babies are often blind when they grow up. Take Stevie Wonder for example.

The body parts that work together to take air into the body and push it back out make up the what?
it makes up the respiratory system.
When does a person need artificial respiration?
Artificial Respiration is a very specific measure when a person cannot breath or when their ability to breathe on their own is or will be compromised. I will deal first with the latter.
A person's ability to breathe on their own may be from an injury or illness, or may be planned (medical procedure) or may occur as a complication of surgery. For examples:
- If a person's airway is compromised (ex. progressive swelling due to allergy reaction), a physician may "tube" the patient to protect the airway and prevent the swelling from closing off the airway completely. A ventilator performs the "artificial breathing".
- When a patient is breathing ineffectively, a physician in the ER or hospital may insert a tube to protect the airway, boost O2 saturation in the blood, protect kidney perfusion, and allow toxins to clear the body (example: an overdose). Intubated and on a ventilator, the patient is in the ICU until the ventilator can be removed.
- A person whose O2 stats dropped during surgery may be tubed and put on a ventilator.
Otherwise, many situations can affect a person''s breathing when at home or out in the community without a doctor or medical equipment nearby. As a couple examples:
- Person has inhaled water (a near drowning). The heart is still beating, but the person is not breathing.
- A person with asthma suddenly cannot breathe, turns blue, and collapses. The heart continues, but the person is not getting any O2.
- The person has thrown a blood clot (a thombus, blood clot, has turned into an embolism, a blood clot traveling through the bloodstream), causing a heart attack. Both respirations and heart beat has stopped.
The problem with respiratory arrest is that it can very quickly lead to cardiac arrest, too. So a Samaritan helping the person should be prepared to lose both.
Samaritans should not try to do artificial respirations when a person is still breathing, which includes:
- audible wheezing - air is still moving
- coughing - air is still moving
- when a person can still talk - they must be breathing to talk
- when a person complains of shortness of breath (SOB) - they are still breathing
NOTE 1: Choking is a separate issue. A rescuer or Samaritan must deal with the obstruction FIRST, then do artificial respirations IF the person does not automatically start breathing.
NOTE 2: Collapsing does NOT automatically mean to start CPR. The person may have just fainted.
What is the result of inspiration and expiration?
This occurs within the respiratory system. During inpiration, the intercostal muscles contract, the diaphragm descends, and the rib cage rises. The thoracic cavity volume increases, stretching the lungs, and the intrapulmonary volume increases. This causes the intrapulmonary pressure to drop. Air flows into the lungs until the intrapulmonary pressure equals the atmospheric pressure. During expiration the intercostal muscles relax, the diaphragm rises, and the rib cage descends. The thoracic cavity volume decreases, causing the the lungs to recoil, and the intrapulmonary volume decreases. This causes the intrapulmonary pressure to rise, and the air flows out of the lungs until the intrapulmonary pressure equals the atmospheric pressure.
What organisms convert oxygen to carbon dioxide?
Humans and most organisms like other mammals, reptiles, birds, insects, water animals convert the inhaled oxygen into carbon dioxide which is a waste gas excreted from the lungs.
