1What does High water potential mean?
Means lots of water particles present (dilute)
2What is tissue fluid?
A dynamic fluid which is the medium by which materials are exchanged between cells and cappilaries
3What is Urea?
The toxic waste product from the break down product of protiens which helps
4What is hydrostatic pressure like in the arterial end of the cappilaries? Why?
High due to the contraction of the left ventricle
5What does the high hydrostatic pressure in the cappliaries do?
It forces water and small molecules out of the cappilaries in a process called ultrafiltration
6What is tissue made from?
blood plasma
7What happens to the concentration of tissue fluid when small molecules get forced out of the cappilaries?
Tissue fluid becomes more dilute
8Where are large plasma protiens found in the cappilaries?
mid cappilary
9Why are large plasma protiens only found in the mid cappilary?
They are too large to diffuse across the membrane
