What is the mechanism that allows oxygen to move from the alveolar into the pulmonary capillary blood?
Simple diffusion
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 three structures constitute the respiratory membrane?
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.
How does ventilation occur?
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.
What 3 types of vessels in lungs?
They are pulmonary artery, pulmonary vein, and capillary.
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.
What is another word for respiratory?
Pulmonary
What body system does the lung belong to?
respiratory syestem
What is the medical term meaning pertaining to respiratory?
Respiratory is generally referred to as "pulmonary".
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.
What are pulmonary diseases?
Pulmonary diseases are conditions that affect the lungs and respiratory system, such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and lung cancer. These diseases can cause difficulty breathing, coughing, chest pain, and other respiratory symptoms. Treatment often involves medication, pulmonary rehabilitation, and sometimes surgery.
Why does oxygen move from the aveloi into the pulmonary capillary blood?
Because of difference in partial pressure
