a. Wall 
b. Lumen
c. Arrangement
d. Surface area

Example:
a. Capillaries are _______ (very thin) This ________ the distance for diffusion to occur and thus, speeds up diffusion of substances

capillary lumen is very narrow in order for the blood flow to slow down and to allow the blood maximum time for diffusion of gases and substances.
capillaries are arranged in numerous thin and small brancehs]]> 2018-08-28 01:05:53 UTC https://padlet.com/ellavarasi2502/capillary/wish/275733043 https://padlet.com/ellavarasi2502/capillary/wish/275733070 a) One cell thick wall- Allows fast diffusion of gases and substances between nlood and tissue cells
b) Narrow lumen- Slows down blood flow, allowing more time for diffusion of substances
c) Numerous small thin branches to reach all respiring body tissues, increase surface area
d) Large surface area to allow fast diffusion of gases and substances between blood and tissue cells.]]> 2018-08-28 01:06:06 UTC https://padlet.com/ellavarasi2502/capillary/wish/275733070 https://padlet.com/ellavarasi2502/capillary/wish/275733078 Capillaries are very thin(one cell thick) This reduces the distance for diffusion to occur and thus,speeds up the rate of diffusion of substances such as O2, CO2,glucose,amino acids and nitrogenous waste between tissue cells and the capillary(endothelial) cells.
The lumen is narrow which slows down blood flow which increases the time for diffusion of substances between the tissue and capillary cells
The structure of the capillary consists of numerous small branches which increases the surface area to volume ratio to increase the rate of diffusion of substances.]]> 2018-08-28 01:06:09 UTC https://padlet.com/ellavarasi2502/capillary/wish/275733078 https://padlet.com/ellavarasi2502/capillary/wish/275733217 a. The wall of the capillary is very thin and it is well cell thick. This allows fast diffusion of gases such as oxygen and carbon dioxide and substances such as nutrients and metabolic wastes between blood and tissue cells. 
b. lumen slows down blood flow to alloow more time for diffusion of substances  thus facilitates maximum exchange of substances 
c. found within organs brances out
d. large surface area to allow fast diffusion of gases amd substances between blood and the tisuue cells ]]> 2018-08-28 01:06:23 UTC https://padlet.com/ellavarasi2502/capillary/wish/275733217 https://padlet.com/ellavarasi2502/capillary/wish/275733410 capillaries are very thin. This decreases the distance for fast diffusion. Lumen is narrow to allow a larger surface area to volume ratio
 for faster diffusion of substances. Numerous branches, small, thin. Allows it to penetrate many tissues to reach all respiring body tissues. Surface Area is large to allow fast diffusion.]]> 2018-08-28 01:07:06 UTC https://padlet.com/ellavarasi2502/capillary/wish/275733410 https://padlet.com/ellavarasi2502/capillary/wish/275733490 2018-08-28 01:07:39 UTC https://padlet.com/ellavarasi2502/capillary/wish/275733490 https://padlet.com/ellavarasi2502/capillary/wish/275733617 A) Walls are one celled thicked to allow fast diffusion of substances and gases.
B) Lumen are very narrow to slow down blood flow to allow more time for diffusion of substance
C) They are arranged in numerous branches and is found in within organs and penetrate many tissues to reach all respiring body tissues
D) surface areas are large to allow fast diffusion of substances between blood and tissue cells

lumen- narrow, slows down the blood flow to allow more time for diffusion of substances, allowing most substances to be diffused
surface area-allows fast diffusion of gases and substances between blood and tissue cells
arrangement- numerous branches which are small and thin because its found within organs and penetrates many tissues to reach all respiring body tissues]]> 2018-08-28 01:10:17 UTC https://padlet.com/ellavarasi2502/capillary/wish/275733802
