Respiration is a metabolic process in which living cells of an organism obtain energy (ATP) by inhaling oxygen and exhaling carbon dioxide as a result of the oxidation of complex organic compounds.
External and cellular respiratory processes comprise the three types of respiration. External respiration is the process of breathing. Gases are inhaled and exhaled. Blood and body cells exchange gases during internal respiration.
The respiratory system has many functions. It does more than just help you inhale and exhale; it also:
- Talk and smell are possible.
- Heating and moisturizing the air to your body temperature and humidity level.
- This organ supplies oxygen to your body’s cells.
- You exhale waste gases, such as carbon dioxide, from your body.
- Airways are protected from harmful substances and irritants.
Types of Respiratory System
Aerobic respiration occurs in the presence of oxygen. Almost all plants and higher animals, such as humans, mammals, and birds, use this type of respiration.
Anaerobic respiration is a type of cellular respiration that occurs without oxygen and is present in all lower species, including bacteria and yeast.
As a form of cellular respiration, it is carried out in the presence of oxygen. Each cell of animals and plants undergoes this continuous process. With the help of a chemical equation, this process can be described.
Oxygen(6O2) + glucose(C6H12O6) Carbon dioxide(6CO2) + Water(6H2O) + Energy(6E) (ATP)
Cellular respiration in the absence of oxygen. The anaerobic respiration chemical equation is
Glucose (C6H12O6) Alcohol 2(C2H5OH) + Carbon dioxide 2(CO2) + Energy (ATP)
A wide range of conditions can affect respiratory system organs and tissues. Airborne irritants, such as viruses or bacteria, caused some infections. Others result from illness or aging.
Inflammation (swelling, irritation, and pain) and other conditions that can affect the respiratory system include the following:
Allergies: People who are allergic to dust, mold, and pollen can develop respiratory allergies from inhaling proteins. As a result, your airways may become inflamed with these proteins.
Asthma: It’s a chronic disease that causes inflammation in the airways, making breathing difficult.
Infection: Pneumonia or bronchitis can result from infection (inflammation of the bronchial tubes). It is not uncommon for people to contract respiratory infections such as influenza or a cold.
Disease: Cancer of the lungs and chronic obstructive pulmonary disease are among the respiratory disorders (COPD). When the respiratory system is compromised, it cannot deliver oxygen throughout the body or remove waste gases.
Inhaling air causes oxygen to enter the bloodstream through your lungs. For your body’s cells to work and grow, they require oxygen. Over the course of a typical day, you breathe nearly 25,000 times. People who suffer from lung disease have trouble inhaling and exhaling. Lung disease affects millions of Americans. Lung illness is the third largest cause of death in the United States when considered as a whole.
Asthma, COPD, influenza, pneumonia, tuberculosis, lung cancer, and many other breathing problems are included in the term lung disease. Respiratory failure is a complication of some lung illnesses.
Blood disorders are not particularly related to heart disease but damages the respiratory system. Respiratory and blood disorders are influenced mainly by the type of lifestyle one is indulging in. It is also possible for respiratory failure to develop slowly. A chronic respiratory failure results from this. Suffocation (extreme fatigue), inability to exercise as before, and sleepiness are some symptoms.
Based on your blood oxygen and carbon dioxide levels, how quickly and shallowly you breathe, the results of lung function tests and other factors, such as how hard you’re working to breathe, a doctor can diagnose respiratory failure in you. As a result of your age, environment or occupation, lifestyle habits, and other medical conditions or medications or procedures, you may be at an increased risk of respiratory failure.
