Respiratory system

nutrition, mobility, and fatigue. Acid-Base Balance is affected in a variety of different ways by gas exchange. For example, with chronic respiratory conditions such as COPD it causes respiratory acidosis which is essentially an increase in carbonic acid and a decrease in pH. Then the opposite would be when you breathe off too much carbon dioxide, this causes respiratory alkalosis because it is a decrease in carbonic acid and an increases in pH. The next interrelated concept is perfusion;…

Coughing is one of the most common health problems. When there is a blockage or irritant in your throat or upper air passages, your brain thinks a foreign element is present and tells your body to cough to remove that element. dry cough diagram Coughing can also be due to a viral infection, common cold, flu, and smoking or health problems such as asthma, tuberculosis, and lung cancer. Some of the symptoms of a cough are itchy throat, chest pain, and congestion. Instead of using…

Chronic inflammation in the airways limits the amount of airflow to the lungs. It is progressive and relates to abnormal inflammatory response in the lungs that affects gas exchange. “This is caused by loss of elastic recoil and airflow obstruction caused by mucosal hypersecretion, mucosal edema, and bronchospasm”. One of the two Chronic Obstructive Pulmonary Disease (COPD) is chronic bronchitis. It is caused when the bronchi and bronchioles become inflamed by exposure to smoke or environmental…

Breathe in People breathe deeply to live others hold in to live longer. Breathe in, and out, feels normal right? Well, what’s not normal is what you may have taken in. It is well known that we all need air to keep the machine that we call our body alive. Cleaner air is essential to maintaining a healthy life, and you may not know that until you take in the problem through nose and mouth. This problem has begun to take its toll on many of our elderly, people with asthma and children; often…

Introduction Antibiotics were initially thought of as a superior drug that could kill many bacterial diseases. Prior to antibiotics, it was hard for anyone to fight a bacteria. However, bacteria are very changing and have begun being able to gain resistance against antibiotics due to overuse, not strong enough dosage of antibiotics, or improper use. By determining the resistance and cross-resistance, one may determine the the relative ability for bacteria to gain resistance to antibiotics. We…

The effect of different breathing patterns on alveolar gas compositions. Introduction Ventilation is the process where the exchange of oxygen (O2) from the air into the lungs and carbon dioxide (CO2) from the blood into the external environment (Silverthorn, 2013). Respiration is essential for all living organisms to survive. Breathing is part of physiological respiration and is required to sustain life. Our lungs are composed of small sacs called alveoli which facilitate the movement of oxygen…

Inhalation is the process of air being drawn into the lungs. During the process of inhalation the external intercostal muscles contract, therefore pulling the chest wall upwards and outwards, these intercostal muscles are between the ribs. As the air is drawn into the lungs, this causes for the thoracic cavity volume to increases, during inspiration the diaphragm also contracts, therefore moving the diaphragm downwards. There are three more muscles that contract during the process of inspiration…

It transports air between the lungs and the body’s exterior the nose, pharynx, mouth, larynx, trachea, bronchi, and bronchioles. Nose and Nasal Cavity Structure: The nose and nasal cavity is line with cilia and capillaries. It secrets mucus, filters debris out in the air and warms the air to 37 degree centigrade. The nose is the face structure comprising of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity; whilst the nasal cavity is the…

Don’t forget to include: Speed of Onset, Age Range, Characteristic Signs & Symptoms, etc. Croup and epiglottitis are two types of respiratory diseases that cause upper airway problems in children. Croup occurs when several viral diseases cause the larynx, trachea, and bronchi to become inflamed. Typically, croup happens after a child develops a cold or another respiratory infection. It usually occurs in children from six months to four years old, and typically worsens at night. During the day,…

The larynx’s main function is to provide airway, protect thr bronchial tree and to allow phonation. When there are growths that develop on the structure, the function is compromised. Laryngeal Cancer is characterized as a disease where masses, cancer cells, begin to accumulate in the larynx. Laryngeal Cancer is a very rare type of cancer, according to cancerresearchuk, approximately twenty-four thousand of patients are diagnosed with Laryngeal Cancer in a year, which is relatively two to five…
