NEET BIOLOGY

Detailed explanation-1: -You can also increase your lung capacity by increasing the length of your inhalations and exhalations. Start by counting how long a natural breath takes. If it takes to the count of five to inhale, it should take to the count of five to exhale. Try to keep them to an equal length.

Detailed explanation-2: -Breathing in When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity.

Detailed explanation-3: -Hyperinflated lungs are larger-than-normal lungs as a result of trapped air. It happens when you can’t exhale, or push out all of the air that’s in your lungs. The air gets trapped and takes up space, which can make it harder to get fresh air into your body. Your lungs try to fix this by taking in more and more air.

Detailed explanation-4: -6 Liters of Capacity. When you inhale, your lungs expand to hold the incoming air. How much air they hold is called lung capacity and varies with a person’s size, age, gender and respiratory health.

Detailed explanation-5: -When you breathe in by enlarging the chest cage, the “balloons” expand as air rushes in to fill the vacuum. When you breathe out, the “balloons” relax and air moves out of the lungs. Tiny blood vessels surround each of the 300 million alveoli in the lungs.
