What is tidal volume?

Back

Tidal volume is the amount of air inhaled or exhaled during normal breathing.

Front

What is the significance of measuring lung capacity?

Back

Measuring lung capacity helps assess respiratory health and can indicate conditions such as asthma or chronic obstructive pulmonary disease (COPD).

Front

What is the role of the diaphragm in respiration?

Back

The diaphragm is a muscle that contracts and relaxes to help draw air into the lungs and push it out.

Front

Why is it important to control variables in a respiratory experiment?

Back

Controlling variables ensures that the results are due to the factor being tested, leading to valid and reliable conclusions.

Front

What is the difference between inhalation and exhalation?

Back

Inhalation is the process of taking air into the lungs, while exhalation is the process of expelling air from the lungs.

Front

What is the purpose of using a ruler in measuring balloon circumference?

Back

A ruler provides a precise measurement of the balloon's circumference, which is essential for accurate data collection.

Front

How does lung capacity vary among individuals?

Back

Lung capacity can vary based on factors such as age, gender, height, and physical fitness.

Front

What is the importance of repeating measurements in experiments?

Back

Repeating measurements increases the reliability of the data and helps identify any anomalies.
