Internal Respiration

The feature of a good blood supply helps gas exchange because it switches with the carbon dioxide and oxygen which helps the process to happen quicker.
The four phases of gas exchange in humans are ventilation, pulmonary diffusion, transport of gases in the blood, and systemic diffusion. Ventilation involves the movement of air in and out of the lungs. Pulmonary diffusion is the exchange of oxygen and carbon dioxide between the alveoli and the blood. Transport of gases involves the carriage of oxygen by hemoglobin and carbon dioxide by plasma. Systemic diffusion is the exchange of oxygen and carbon dioxide between the blood and body tissues.
AlveoliGaseous exchange takes place in the alveoli of the lung
systemic circulation
Emphysema decreases the total area available for gas exchange in the lungs by damaging and destroying the alveoli. This reduces the surface area where oxygen can pass into the bloodstream and carbon dioxide can be removed, leading to impaired breathing and inadequate oxygenation of the body.
Gas exchange is a function of respiration not digestion.
Alveoli is where gas exchange occurs.
The pulmonary system is responsible for exchanging oxygen and carbon dioxide between the lungs and blood, while the systemic system delivers oxygen and nutrients to the body's tissues and removes waste products. The pulmonary system deals with gas exchange specifically in the lungs, while the systemic system involves the entire body's circulation of blood.
Pulmonary Circulation carries deoxygenated blood to the lungs to receive oxygen, while the Systemic Circulation carries the oxygenated blood throughout the body so the oxygen can be used, returning to the Pulmonary Circulation as deoxygenated blood.
