Answer 2

Active respiration does not include thorax.

The function of following parts are :-

1. Trachea

• It is a U shaped tube which connects the human voice box (larynx) with lungs.
• It is also known as air pipe. It is a key part of the respiratory system.
• When we breathe, air travels through Trachea from nose to lungs.

   2. Diaphragm

• It is a dome shaped muscle present below the lungs.
• It continually contracts and flattens when we breathe in and out.

   3. Thorax

• It is the area of the body between the neck and abdomen.
• It consists of important organs like heart, lungs and liver.
• It is supported by ribs and spine.

   4. Intercostal Muscles

• These are present within the rib cage in three layers.
• These muscles assist ribs and chest cavity to come back to their original position during exhalation.
• These muscles combine to fill gaps within ribs and assist the respiratory system to work properly.

Hence, we can say that active respiration does not include thorax.
