Breathing starts when you inhale air into your nose or mouth. It travels down the back of your throat and into your windpipe, which is divided into air passages called bronchial tubes. For your lungs to perform their best, these airways need to be open. They should be free from inflammation or swelling and extra mucus.
What is the respiratory system?
Respiratory system (anatomy diagram) So far, you have seen how the thoracic cage is a frame that encloses the respiratory system and allows breathing to take place. Several muscles that span several regions of the body, such as the thoracic wall itself, neck, shoulder girdle and abdomen, act upon this structure.
How to breathe without the thoracic cage?
While the thoracic cage offers a resistant, yet flexible framework, it would be impossible for you to breathe without the action of the thoracic muscles. Further details will be given below, but ventilation is carried out by expanding and contracting the lungs. One way of doing this is to change the anteroposterior diameter of the chest cavity by elevating or depressing the ribs. The most important muscles raising the ribcage are the external intercostal muscles. These muscles are part of the intercostal muscle group located in the intercostal spaces between the ribs. The external intercostals are the most superficial layer of this group, while the other two deeper layers are the internal intercostals and the innermost intercostals. There are 11 pairs of external intercostals, extending between the tubercles of the ribs and the costochondral joints. They run in an infero-anterior direction between the borders of two adjacent ribs.
What is the movement of air between the atmosphere and the lung alveoli?

How much ATP does aerobic respiration produce?
The process of aerobic respiration produces a huge amount of ATP from each molecule of sugar. In fact, each molecule of sugar digested by a plant or animal cell yields 36 molecules of ATP! By comparison, fermentation usually only produces 2-4 molecules of ATP.
How does aerobic respiration work?
Instead of directly reducing intermediates of the Krebs cycle, aerobic respiration uses oxygen as the final electron receptor. But first, the electrons and protons bound to electron carriers (such as NADH), are processed through the electron transport chain. This chain of proteins within the mitochondrial membrane uses the energy from these electrons to pump protons to one side of the membrane. This creates an electromotive force, which is utilized by the protein complex ATP synthase phosphorylate a large number of ATD molecules, creating ATP.
Why is aerobic respiration so efficient?
Aerobic respiration is so efficient because oxygen is the most powerful electron acceptor found in nature. Oxygen “loves” electrons – and its love of electrons “pulls” them through the electron transport chain of the mitochondria.
