Study Notes
- Breathing is an involuntary process that occurs without realization, but it can be controlled.
- The respiratory system is responsible for breathing, and it consists of the lungs and airways.
- The airways are tubes through which air passes until it reaches the lungs and are made up of the nose, mouth, pharynx, larynx, trachea, bronchi, and alveoli.
- Inhalation is the phase when air enters the lungs, and exhalation is the phase when we expel the air we don't use.
- The larynx contains vocal cords that allow us to speak or sing.
- When air is breathed in, it passes through the nose and mouth, then through the pharynx and into the larynx.
- The trachea is divided into two tubes called bronchi, which branch into narrower tubes called bronchials.
- Each bronchial leads into many small sacks called alveoli, where gas exchange takes place.
- In the alveoli, oxygen in the air passes into the blood through small blood vessels, and carbon dioxide travels back through the respiratory system to be expelled outside.
- The respiratory system is important and needs to be taken care of by practicing sports and taking care of nature to avoid polluting the air.
- Healthy lungs are pink, but they can turn brown and stop working properly when exposed to tobacco smoke or polluted air.
- Damaging lungs can lead to tiredness and feeling unwell, so it's essential to exercise regularly and avoid smoking to maintain healthy lungs.
