Want this question answered?
Carbon dioxide is very soluble in aqueous solutions. There is a lot less C02 in blood than in even flat soda. In general there is an equilibrium between C02 and H2CO3 and then H2C03 disassociates into H+ and HC03- and it is the change in pH that triggers the physiological response.
it diffuses thru the alveolar cappilary membrane
Intra-alveolar means between the alveoli. Focal means within a limited area. There are both adjectives and the phrase is missing a noun. (In other words, focal intra-alveolar...what?)
The alveoli is just one cell layer thick so that diffusion of gasses between the capillaries and the alveoli is easy. Simple squamous epithelium are found in the capillary walls and the alveolar walls. They are thin so diffusion is easy.
the active boundary between plates is a ?
no
These are called the alveoli capillaries.
The arcuate artery.
Yes it is. Infact, the alveolus is made up of a single layer of epithelial tissue.
Alveoli are site of gas exchange. Actual diffusion of gases occurs at interstitial space between capillaries and alveolar cells.
Exchange of carbon-di-oxide for oxygen takes place between capillaries and tissues.The exchange of gases occur through diffusion.In Lungs, oxygen from inhaled air in the alveolar space moves into the RBCs in the capillaries and the carbon-di-oxide moves form the RBCs in the capillaries to the alveolar space which is exhaled during respiration.In other tissues, the Oxygen is given to the tissues and carbon-di-oxide is taken from the tissues into the blood.Many gases can be exchanged across the capillaries but the exchange of oxygen and carbon-di-oxide occurs normally in the body.
Oxygen passes from the air sacs in the lungs to the blood in the capillaries, carbon dioxide passes the other way.

That sounds like a general description of the LUNGS.The lungs are loaded with pulmonary alveoli: small outpouchings along the walls of the alveolar sacs and alveolar ducts; through them, gas exchange takes place between alveolar gas and pulmonary capillary blood.
