Little Breathers

The video explains the body's natural response to breathing and diving, known as the diving response, which conserves oxygen by stopping breathing. It discusses how training can help override this response, allowing humans to hold their breath longer, similar to animals like otters and dolphins. Techniques such as breathing through pursed lips are suggested to improve lung capacity and breath control.

What physiological change occurs in our body when the diving response is triggered?

• Decreased blood pressure

• Increased heart rate

• Production of more red blood cells

• Increased oxygen consumption

How can we train our body to control the diving response?

• By holding our breath for short periods

• By breathing through tightly pursed lips

• By swimming in warm water

• By increasing physical activity

What is the effect of breathing through tightly pursed lips?

• It decreases lung capacity

• It shortens the breath-holding time

• It stretches the lungs for longer

• It increases the heart rate

With practice, how long can humans potentially hold their breath?

• Up to 5 minutes

• Up to 11 minutes

• Up to 7 minutes

• Up to 9 minutes

Which animals have a similar breath-holding capacity to trained humans?

• Sharks and whales

• Otters, dolphins, and beavers

• Penguins and polar bears

• Seals and sea lions
