MICROANATOMY

Detailed explanation-1: -When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.

Detailed explanation-2: -Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system’s main job is to transport oxygen and remove extra carbon dioxide.

Detailed explanation-3: -CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2).

Detailed explanation-4: -Your lungs bring fresh oxygen into your body. They remove the carbon dioxide and other waste gases that your body’s doesn’t need.

Detailed explanation-5: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
