Dive into the respiratory system and its common diseases with this guide! Understanding how your lungs work and... Show more
The respiratory system performs the crucial function of gas exchange, bringing oxygen in and removing carbon dioxide from our bodies. When this system faces challenges, various diseases and disorders can develop, affecting our ability to breathe properly.
Medical assistants play a key role in diagnosing respiratory conditions through procedures like tuberculosis testing, spirometry (measuring lung function), pulse oximetry (measuring blood oxygen), and collecting sputum samples. They also assist with more advanced procedures like bronchoscopy, where doctors examine the airways directly.
Understanding respiratory diseases requires knowledge of both the upper respiratory tract (nose, pharynx, larynx) and lower respiratory tract (trachea, bronchial tubes, lungs). Each part has specific vulnerabilities to different conditions.
Quick Fact Your right lung has three lobes while your left lung has only two lobes - this asymmetry accommodates space for your heart!
The common cold tops the list of respiratory infections, primarily affecting the upper respiratory tract. Though typically viral, it can open the door to bacterial infections in the throat, sinuses, or ears. These secondary infections often need specific treatments beyond what helps the initial cold.
Sinusitis involves inflammation of the sinuses, either from a cold or allergies. Bacterial sinusitis requires antibiotics, while allergy-related cases respond to decongestants, antihistamines, and pain relievers.
Pneumonia represents a more serious lower respiratory infection that comes in several forms. Bacterial infections can target the bronchi (bronchopneumonia) or an entire lung lobe (lobar pneumonia). Viral pneumonia typically affects the areas surrounding lung cells, while fungal pneumonia comes from organisms like Aspergillus or Candida.
People at higher risk for serious respiratory infections include hospitalized patients, the elderly, substance users, and those with compromised immune systems. Early recognition of symptoms can lead to faster treatment and better outcomes.
Tuberculosis (TB) remains one of the world's deadliest infections, affecting about one-third of the global population. This bacterial disease spreads through sputum (mixture of saliva and mucus) and requires long-term medication. Many people have "latent TB," meaning they're infected but not sick or contagious.
Chronic Obstructive Pulmonary Disease (COPD) describes a group of conditions with chronic airway obstruction, typically caused by smoking or chemical exposure. People with COPD often experience orthopnea - needing to sit or stand upright to breathe comfortably.
Asthma involves inflammation and bronchospasm that restrict airflow, causing coughing, difficulty breathing, wheezing, and chest tightness. Meanwhile, emphysema damages the alveoli (air sacs where oxygen exchange occurs), reducing lung elasticity and making breathing difficult.
Remember This Obstructive sleep apnea occurs when throat muscles relax during sleep, narrowing or closing the airway. A CPAP machine keeps airways open during sleep and can dramatically improve quality of life for sufferers.
Lung cancer leads cancer-related deaths in the US, with 90-95% of cases linked to cigarette smoking. Tumors may be primary (originating in the lungs) or secondary (spread from elsewhere). Early detection dramatically improves survival chances, but many cases are found too late.
Laryngeal cancer primarily affects men (90% of cases) and is strongly associated with tobacco use and chronic alcohol consumption. Treatment often requires removing part or all of the larynx, which may necessitate a tracheostomy and special devices for communication.
Respiratory conditions range from mild to life-threatening. The common cold primarily affects the upper respiratory tract but can lead to more serious infections. Sinusitis involves inflammation of any of the four sinus cavities. Various types of pneumonia affect different parts of the respiratory system.
COPD conditions like emphysema cause long-term breathing difficulties as lung tissues lose elasticity and function. Understanding these conditions helps recognize symptoms early and seek appropriate treatment, which can significantly improve outcomes and quality of life.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think itโs very much worth it and youโll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still donโt get it!!!

Knowunity is the BEST app Iโve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
