Saliva question

Post by JRT » Sat Jul 15, 2006 1:56 am

Saliva glands produce saliva.

Saliva is over 99% water.

Where do the saliva glands get the water from? The blood stream?

Yes, from circulatory system: blood capillaries and lymph vessels ;)

Thank you!

Do you know what % of the water comes from the blood and what % comes from the lymph vessels?

this is the answer to ur 2nd question

it is not possible to deciper the percentage which is obtained from blood and that of lymph as lymph empties into the blood vessels(inferior vena cava) and then the 2 are collectively known as blood.

Plus the water comes from the intercellular fluid actually, so you can not tell where the water came from. In theory most of the water would come from the blood, but there is no way of saying for sure.
