My book consists of following lines."The interstitial fluid is entrapped in minute space among proteoglycan filaments. This combination of proteoglycan filaments and the fluid entrapped within them has a characteristic of gel so called tissue gel. Instead of flowing interstitial fluid mainly diffuses through gel. This diffuion allows rapid transport of interstitium of water nutrients,oxygen,cell excreta e.t.c. I can't get the meaning of these lines. I tried to search on net but didn't get a satisfactory explanation. Please explain this to me.
"Tissue gel" is not a common term in human anatomy or histology.
According to Wikipedia:
A gel is a solid jelly-like soft material that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state.
In the human body, the interstitium (the space between the cells) is made of connective tissue fibers and liquid, which has physical properties of a gel.
You are probably confused because of this sentence which is messed up: "This diffuion allows rapid transport of interstitium of water nutrients,oxygen,cell excreta e.t.c. " It should be: "The diffusion allows rapid transport of nutrients, oxygen, cell excreta, etc, through the interstitium."
