The respiratory system is the network of organs and tissues that help to breathe. This system helps the body to absorb oxygen from the air so the organs can work. It also cleans waste gases, such as carbon dioxide, from the blood. Common problems include allergies, diseases or infections. It includes the 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. The respiratory system has many functions besides helping you inhale (breathe in) and exhale (breathe out). It allows to talk and to smell; warms air to match the body temperature and moisturizes it to the humidity level the body needs; delivers oxygen to the cells in the body; removes waste gases, including carbon dioxide, from the body when you exhale and protects the airways from harmful substances and irritants.
