MICROANATOMY

Detailed explanation-1: -The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

Detailed explanation-2: -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).

Detailed explanation-3: -Your lungs are the pair of spongy, pinkish-gray organs in your chest. 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).

Detailed explanation-4: -The function of the lung is to get oxygen from the air to the blood, performed by the alveoli. The alveoli are a single cell membrane that allows for gas exchange to the pulmonary vasculature. There are a couple of muscles that help with inspiration and expiration, such as the diaphragm and intercostal muscles.
