Study Notes
- The speaker emphasizes the importance of breathing throughout the conversation.
- The topic of discussion is the Human Respiratory System.
- When we breathe in, we take oxygen from the air through our nostrils.
- Nostrils have tiny hairs that filter out dust particles.
- Air then travels through the windpipe (Trachea), which filters the air further.
- The Trachea branches out into two bronchi tubes.
- Bronchi carry air into each lung, which has lobes filled with air sacs called alveoli.
- Alveoli are where the exchange of oxygen and carbon dioxide occurs.
- Blood picks up oxygen and releases carbon dioxide in this process.
- The diaphragm, a muscle beneath the lungs, contracts when we breathe in and expands when we breathe out.
- Humans breathe approximately 20,000 times in one day.
- Lungs are the only organs that can float on water.
