Why Is Only Half of My Nose Working?

The video explains the nasal cycle, a process where nostrils alternate in airflow to aid breathing and smell. This cycle is more noticeable during congestion. It helps maintain respiratory health by allowing cilia in the nasal passages to rest, preventing them from drying out. The cycle also enhances smell detection by varying airflow speed, allowing different odor molecules to bind to nasal receptors. The video concludes with a personal reflection on the nasal cycle.

What is the nasal cycle primarily responsible for?

• Reducing the sense of smell

• Increasing the speed of airflow

• Causing permanent nasal congestion

• Switching the roles of nostrils in breathing

Why do humans have two nostrils?

• To reduce the need for breathing

• To increase the size of the nose

• To split the workload and improve smelling

• To make the nose look symmetrical

How does the nasal cycle benefit the cilia in the nasal passages?

• By increasing mucus production

• By giving them a break to prevent drying

• By drying them out

• By reducing the need for air filtration

What role does airflow play in detecting different smells?

• Varying airflow helps detect a range of smells

• Faster airflow helps detect all smells

• Airflow has no impact on smell detection

• Slower airflow is better for all smells

Why might some odor chemicals require faster airflow to be detected?

• They are less sticky and need more time

• They are stickier and need to move quickly

• They are heavier and need slower movement

• They are lighter and need no airflow
