Question
. Substances that diffuse through the gaps in the capillary endothelium, rather than through some other route, include a. glucose b. CO2 c. proteins. d. All of these pass through endothelial pores. The blood that exchanges O2 and CO2 with an alveolus a. is contained in capillaries that are found inside the alveolus. b. is contained in capillaries that surround the alveolus. c. fills the hollow core of the alveolus d. flows around the alveolus in direct contact with the epithelial cells that form the alveolar wall. A person who was unable to produce surfactants in his lungs would experience a. an increase in anatomical dead space. b. a decrease in anatomical dead space. c. an increased tendency of the lungs to contract. d. a decreased tendency of the lungs to contract.Explanation / Answer
There are 3 types of cappilaries are there. They are Continues, Fenestrated, Sinusoid. Glucose diffuse through the gaps in the capillary endothelium of continues cappillary. CO2 through the Fenestrated cappillary. Proteins are through the Sinusoid cappillary. So the answer is " All of these pass through endothelial pores ".
The blood that exchanges O2 and CO2 with an alveolus " is contained in capillaries that surrounded the alveolus".
A person who was unable to produce surfactants in his lungs would experience " a decreased tendency of the lungs to contract".
