Diffusion
The transport mechanism necessary for the movement of oxygen from the alveoli across the pulmonary capillary membranes into the blood is primarily diffusion. Oxygen diffuses from areas of higher concentration in the alveoli to areas of lower concentration in the blood within the pulmonary capillaries. This process occurs due to the partial pressure gradient of oxygen, where the oxygen concentration is higher in the alveoli than in the deoxygenated blood.
Simple diffusion
a pulmonary artieriole is part of the respiratory system. inside the respiratory system is an organ called alveoli and the alveoli are covered in a network of capillary. the job of the pulmonary arteriole is to carry deoxygenated blood into the capillary network.
The respiratory membrane consists of three main structures: the alveolar epithelium, the capillary endothelium, and the fused basement membranes of both. The alveolar epithelium is a thin layer of cells lining the alveoli, while the capillary endothelium forms the inner lining of the pulmonary capillaries. Together, these structures facilitate efficient gas exchange between the air in the alveoli and the blood in the capillaries.
Pulmonary ventilation occurs as a person inhales and exhales air and air is exchanged between the atmosphere and the alveoli of the lungs. During this, the pulmonary capillary blood gains oxygen and loses carbon dioxide.
They are pulmonary artery, pulmonary vein, and capillary.
Yes gas is transferred through the alveolar/capillary membrane in the alveolus. Gas moves from the alveolar air sacs to the pulmonary capillaries.
Pulmonary
respiratory syestem
Respiratory is generally referred to as "pulmonary".
Pulmonary agents can cause pulmonary edema by disrupting the normal balance of fluid in the lungs, leading to fluid accumulation in the air sacs (alveoli) and interstitial spaces. This can result from mechanisms such as increased capillary permeability, inflammation, or increased hydrostatic pressure in the pulmonary circulation. Ultimately, this leads to impaired gas exchange and breathing difficulties.
