C
Feedback:
Although considered a connective tissue, blood differs from other connective tissues in that its cells are not fixed, but move freely in the liquid portion of the blood. Cells being heavier, thicker, and more viscous than water are a generic property of blood. Possessing an adhesive quality despite being a liquid is related to its ability to form solid clots. The composition of lymph is the same, but it is lower in protein content.
