Study Notes
Human Respiratory System
- The human body needs oxygen to breathe, and it gets oxygen from the air around us.
- Without oxygen, the body would be like a car without fuel, and it's essential for survival.
Breathing Process
- When we breathe in, oxygen is taken in through the nostrils, where tiny hair obstructs dust particles.
- The air then passes through the windpipe (Trachea), which filters the air we inhale.
- The Trachea branches out into two tubes called Bronchi, where tiny hair called Cilia move back and forth to move mucus inside.
- The mucus is a sticky substance that collects germs and other particles that might harm the lungs.
Lungs
- The Bronchi carry air into each lung, with the right lung having three lobes and the left lung having two lobes.
- The left lung is slightly smaller in size to give space to the heart.
- The lobes are filled with small and spongy air sacs called alveoli, where the exchange of oxygen and carbon dioxide happens.
- It is here that the blood picks up oxygen and lets go of carbon dioxide.
Diaphragm
- The Diaphragm is a dome-shaped muscle located beneath the lungs that contracts when we breathe in and expands when we breathe out.
- It separates the chest cavity from the abdominal cavity.
Trivia
- The lungs are the only organs that can float on water.
- A person breathes approximately 20,000 times in one day.
Human Respiratory System
- Oxygen is essential for human survival, and the body obtains it from the air.
- The absence of oxygen would render the body unable to function, similar to a car without fuel.
Breathing Process
- Oxygen is inhaled through the nostrils, where tiny hair obstructs dust particles.
- The air then passes through the trachea, which filters the inhaled air.
- The trachea branches into two tubes called bronchi, where cilia (tiny hair) move back and forth to move mucus inside.
- Mucus is a sticky substance that collects germs and other particles that might harm the lungs.
Lungs
- The bronchi carry air into each lung, with the right lung having three lobes and the left lung having two lobes.
- The left lung is smaller in size to accommodate the heart.
- The lobes are filled with small, spongy air sacs called alveoli, where oxygen and carbon dioxide are exchanged.
- It is in the alveoli that the blood picks up oxygen and releases carbon dioxide.
Diaphragm
- The diaphragm is a dome-shaped muscle located beneath the lungs that contracts during inhalation and expands during exhalation.
- The diaphragm separates the chest cavity from the abdominal cavity.
Trivia
- The lungs are capable of floating on water due to their unique structure.
- An average person takes approximately 20,000 breaths in a day.
