![]() finally the infusion which is the process from which the cardiovascular system pumps sanfre to the lungs.The respiratory system consists of a conducting zone ( anatomic dead space i.e., the airways of the mouth, nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles) and a respiratory zone ( lung parenchyma i.e., respiratory bronchioles, alveolar ducts, alveolar sacs). Diffusion is the spontaneous movement of gases between the Alveoli and the blood of the lung capillaries without any or effort of the organism. Ventilation is the process by which air enters and leaves the lungs. This procedure carries 3 very important procedures for transferring oxygen from outside air to blood flowing into the lungs of which are ventation, diffusion, and infusion. inhaled oxygen passes from the Alveoli to the blood inside the capillaries, and the carbon dioxide passes from the blood inside the capillaries into the air of the Alveoli. Gas exchange takes place in the millions of alveoli in the lungs and capillaries that surround it. after that process the blood is propelled through the pulmonary artery into the lungs, where oxygen is collected and the carbon dioxide is released. Oxygen-free, carbon-laden blood returns to the right side of the Heart through the inferior vena cava and upper vena cava. ![]() Oxygenated blood circulates from the lungs through the pulmunar veins, and when it reaches the left side of the heart it is expared into the rest of the organs. Likewise the carbon dioxide passes from the blood to the inside of the sockets from where it is exhaled to the outside. ![]() oxygen passes through a barrier between the air and blood that has approximately a thicker of a micron very quickly, this oxygen xuando passes through the barrier reaches the blood circulating through the capillaries. The process of the respiratory system in the gas exchange between alveoli and blood, and the gas exchange between blood and the body tissues are layers of cells that line the surrounding sockets and capillaries that are occupied by the thickness of a single cell and are in contact with each other. ![]()
