Respiratory System

The Respiratory Exchange Ratio (or RER) is a measurement used in sport and health sciences. It relates to the relationship between the amount of oxygen taken up and the amount carbon-dioxide expelled during breathing cycles.

During exercise (and at rest) this measurement is used to determine how your body is utilising your available enegry stores.

An RER assessment is done using a respiratory gas anaylser, or a using a more traditional method using Douglas Bags.

The ratio is calculated by: the volume of carbon-dioxide expelled, divided by the volume of oxygen consumed. The resulting value can give a good (but not definitive) indication to the type of energy that your body is primarily consuming - (fat (FFA - Free Fatty Acids) or carbohydrate (CHO)).

Although RER is a good indicator of energy consumption, it should be noted the results can be tainted by other processes happening in the body (bicarbonate buffering of hydrogen ions during energy liberation cycles) which affect the reading of CO2 expelled.

The lungs are essential in extracting oxygen from the air and transferring it to the blood. Once in the blood, red blood cells carry oxygen to all parts of the body to support cellular functions.

Moisture in exhaled air increases because as we breathe in, our respiratory system warms and humidifies the air to ensure optimal conditions for gas exchange in the lungs. This process adds moisture to the air which is then exhaled when we breathe out.

The best way to administer oxygen to a child in moderate respiratory distress is through a nasal cannula at a flow rate appropriate for the child's age and condition. Monitoring the child's oxygen saturation levels and adjusting the flow rate accordingly is important. Seek medical help if the child's condition does not improve.

Chewing food thoroughly before swallowing helps to prevent food particles from entering the respiratory tract. Swallowing with a tilted head and avoiding talking or laughing with food in your mouth also reduces the risk of food going down the wrong way. If food does enter the respiratory tract, it can lead to choking or aspiration pneumonia.

The respiratory passages are lined with a mucous membrane called the respiratory epithelium. This epithelium helps trap foreign particles like dust and bacteria, and also contains cilia that help sweep these particles out of the respiratory system.

This is actually located in the brainstem in particular the medulla oblongata. This is the primitive part of the brain which we have no "concious" control over (it is autonomic) and ensures that we breathe above all costs (i.e. you can't forcibly hold your breath and suffocate yourself). This part of the brain however can be influenced by other parts of the brain which we do have control over.

A very wide range of diseases or toxic substances, including some drugs, can cause ARDS. They include: Breathing in (aspiration) of the stomach contents when regurgitated, or salt water or fresh water from nearly drowning.

Yes, emphysema can decrease respiratory volume by damaging the air sacs in the lungs, which reduces the lungs' ability to efficiently exchange oxygen and carbon dioxide. This damage can lead to symptoms such as shortness of breath and decreased exercise tolerance.

Proper control of the respiratory passages depends upon the coordination of muscles in the diaphragm, intercostal muscles, and other accessory respiratory muscles. Additionally, the autonomic nervous system plays a key role in regulating the dilation and constriction of the airways through the action of the sympathetic and parasympathetic nerves. This control ensures the optimal exchange of oxygen and carbon dioxide in the lungs.

A patient choking on a hot dog may initially result in respiratory alkalosis due to hyperventilation in response to decreased oxygen levels. If the obstruction continues and impairs adequate gas exchange, it can progress to respiratory acidosis as carbon dioxide builds up in the bloodstream.

Air moves in and out of the external nares, also known as the nostrils. During inhalation, air enters the respiratory system through the external nares, where it is filtered, humidified, and warmed before reaching the lungs. During exhalation, air exits the respiratory system through the same external nares.

Stridor is commonly associated with conditions that cause airway obstruction, such as croup, epiglottitis, and foreign body inhalation. It is a high-pitched, inspiratory sound that occurs due to turbulent airflow through a partially obstructed airway. Treatment depends on the underlying cause and may include medications, positioning, or in severe cases, airway management procedures.

There is no specific term "clvn" in respiratory medicine. It is possible that this may be an abbreviation or typo. Can you provide more context or clarify the term?

Well, the next region that air passes is consequently the nasal cavity. But beyond that, it flows through the nasal and paranasal sinuses, and eventually makes it way down to the larynx and pharynx.

The respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide. It involves processes like breathing, gas exchange in the lungs, and transport of gases in the blood to maintain the body's overall balance of oxygen and carbon dioxide levels.

The average resting respiratory rate is 15-16 breaths per minute. Therefore, there would be 15-16 inhalations and 15-16 exhalations per minute.

A snake has one lung. Humans can also live with only one lung. The one lung compensates for not having two.

1. Introduction: Start by discussing the importance of the respiratory system in the body and its role in oxygenating the blood and removing carbon dioxide.
2. Major parts of the respiratory system: Explain the key components such as the nasal cavity, trachea, lungs, diaphragm, bronchi, and alveoli. Discuss their functions and how they work together to facilitate breathing.
3. Demonstration: Show a model or diagram of the respiratory system and explain how air flows through each of the major parts during inhalation and exhalation.
4. Activity: Engage students in a breathing exercise to demonstrate the movement of the diaphragm and expansion of the chest cavity during inhalation.
5. Recap and assessment: Review the major parts of the respiratory system and their functions. Ask students to identify and describe each part to assess their understanding.

The smallest functional unit of respiratory system is alveoli. Gaseous exchange takes place here. * The alveoli are attached to bronchules. * bronchules to bronchus. * bronchus to trachea the windpipe.

Anaerobic respiration is the process of producing energy from glucose without the use of oxygen. It results in the production of less ATP compared to aerobic respiration and produces byproducts such as lactic acid or ethanol.
