Detailed explanation-1: -The act of physically taking in oxygen and releasing carbon dioxide is known as breathing. Inspiration and expiration are the two key steps in the breathing mechanism. The external intercostal muscles and the diaphragm contract during inspiration. When the diaphragm and intercostal muscles relax, exhalation happens.
Detailed explanation-2: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Detailed explanation-3: -When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.
Detailed explanation-4: -Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Detailed explanation-5: -What is thoracentesis? Thoracentesis is a procedure to remove fluid or air from around the lungs. A needle is put through the chest wall into the pleural space. The pleural space is the thin gap between the pleura of the lung and of the inner chest wall.
