Blood
Blood is a tissue. Tissues are groups of similar cells that act together to perform a similar function. Blood is made up of a fluid called plasma, which has three parts to it:
Red blood cells
- Red blood cells are suspended in blood plasma.
White blood cells
- White blood cells are suspended in blood plasma.
Platelets
- Platelets are suspended in blood plasma.
Test yourself on Blood Components
Tissues are groups of similar cells that act together to perform a similar function. Would one single red blood cell, on its own, count as a tissue?
A tissue must be made of cells. Blood plasma is described as a fluid. Would plasma by itself, with no cells in it, count as a tissue?
