Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. The average human respiratory rate is 30–60 breaths per minute at birth, [2] decreasing to 12–20 breaths per minute in adults. [3]
The right lung is bigger than the left, and the left lung shares space in the chest with the heart. The lungs together weigh approximately 1.3 kilograms (2.9 lb), and the right is heavier. The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles , which receive air breathed in ...
Oxygenated air therefore flows constantly (during the entire breathing cycle) in a single direction through the parabronchi. [53] The blood flow through the bird lung is at right angles to the flow of air through the parabronchi, forming a cross-current flow exchange system (Fig. 19).
Right-side chest pain may be a sign of something less worrisome, like muscle pain. Or it may indicate a more serious health problem related to the heart or lungs.
Diaphragmatic breathing, paradoxical movement of the diaphragm outwards during inspiration; Intercostal indrawing; Decreased chest–chest movement on the affected side; An increased jugular venous pressure, indicating possible right heart failure [5] The anterior and posterior chest wall are also inspected for any abnormalities, which may include:
Unfortunately, the answer is quite broad—there are so many medical conditions that can cause pain in the chest. It can be as simple as a pulled muscle or as complicated as pulmonary embolism ...
The lungs are not capable of inflating themselves, and will expand only when there is an increase in the volume of the thoracic cavity. [6] [7] In humans, as in the other mammals, this is achieved primarily through the contraction of the diaphragm, but also by the contraction of the intercostal muscles which pull the rib cage upwards and outwards as shown in the diagrams on the right.

Luckily, there are several doctor-recommended techniques on how to get rid of chest congestion that you can try before resorting to a visit to the doctor’s office.
