Expert Answer:
1. Epiglottis- The main function of the epiglottis is to seal off the windpipe during eating, so that food is not inhaled.
2. Haemoglobin- It carries oxygen from the lungs to the tissues and return CO2 from the tissue to the lungs.
3. Alveolar sacs- It allows oxygen and carbon dioxide to move between the lungs and bloodstream.
4. Larynx- It keeps food and drink out of the airways during swallowing.It also produces voice by modulation of air passing through vocal cords.
5. Diaphragm- The contraction and expansion of the diaphragm helps to inhale and exhale air from the lungs.
Various types of ribs include-
- True ribs: The first 7 pairs of ribs are attached in the front to the sternum with the help of a hyaline cartilage. They are called true ribs.
- False ribs: The next 3 pairs of ribs are fused and attached to the sternum indirectly. These are called false ribs. The 8th, 9th and 10th pair of ribs join the 7th rib.
- Floating ribs: The last two, 11th and 12th pairs of ribs, are not attached to the sternum but hang freely. These are called floating ribs.
