Does the diffusion of respiratory gases take place at the membranes between the alveolar ducts and lymphatic capillaries?

no


What is the name of the tiny blood vessels that surround the alveoli in the lungs?

These are called the alveoli capillaries.


The artery lies on the boundary between capillaries in the cortex and medulla of the kidney?

The arcuate artery.


Is alveolar epithelium a structure between the air in the alveoli and the blood in the capillaries?

Yes it is. Infact, the alveolus is made up of a single layer of epithelial tissue.


Where is the site where Gases are exchanged?

Alveoli are site of gas exchange. Actual diffusion of gases occurs at interstitial space between capillaries and alveolar cells.


Exchange of gases occurs between capillaries and what structure?

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.


Exchange of gases between alveolar air and pulmonary capillary blood?

Oxygen passes from the air sacs in the lungs to the blood in the capillaries, carbon dioxide passes the other way.


What keeps the surface between the air and the alveolar cells moist in the lung?

alveolar fluid


Where does carbon dioxide enter the bloodstream?

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.


The exchange of gases between alveolar air and blood is due to?

it diffuses thru the alveolar cappilary membrane


Which part of the respiratory system consists of air sacs with capillaries?

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.


What is intra-alveolar?

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?)
