The pulmonary capillary plexus is a network of tiny blood vessels located in the lungs, primarily surrounding the alveoli (air sacs) where gas exchange occurs. Its main function is to facilitate the transfer of oxygen from the inhaled air into the bloodstream while allowing carbon dioxide to be expelled from the blood into the alveoli for exhalation. This efficient exchange is crucial for maintaining proper oxygenation of the body and removing metabolic waste gases. The plexus also helps regulate blood flow and pressure within the pulmonary circulation.

What is the function of a pulmonary arteriole?

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.

What are the two primary nerve plexuses regulating digestive function?

The two primary nerve plexuses regulating digestive function are the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). They are part of the enteric nervous system and play important roles in controlling gastrointestinal motility, secretion, and blood flow.

How do pulmonary agents cause pulmonary edema?

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.

Does the gas exchange function of the respiratory system occur in the alveoli?

Yes gas is transferred through the alveolar/capillary membrane in the alveolus. Gas moves from the alveolar air sacs to the pulmonary capillaries.


Why does oxygen move from the aveloi into the pulmonary capillary blood?

Because of difference in partial pressure
