Blood is a connective tissue that has a liquid matrix.
Connective tissues have an extracellular matrix that gives them their characteristic properties. Blood is a liquid connective tissue that has a fluid matrix.
One might be tempted to say it is a liquid tissue, but it isn't the only kind of liquid tissue. Semen is another example of a liquid tissue. Blood is unique in the sence it is a tissue which carries oxygen and nutrients to other tissues and removes waste material. FYI: a "tissue" is defined as a mass of cells disperced in a non-living matrix. In blood the matrix is the blood plasma. In bone, it is the mineral calcium triphosphate.
blood and lymph are two types of connective tissue that have a liquid intercellular matrix.
What is The Matrix? The answer is out there, Neo, and it's looking for you, and it will find you if you want it to.
Blood.

The bones have the largest amount of minerals, calcium and phosphorus, in its extracellular matrix. Teeth, which are specialized bone, have additional enamel that makes them even stronger. That answer has nothing to do with the question asked....but the answer is connective tissue.
It is fluid.
Blood is a connective tissue. Blood cells like erythrocytes are cells, while the plasma makes up the matrix. Together, they form the only fluid tissue in your body.
Blood is considered connective tissue because it is cells (formed elements) surrounded by a non-living matrix (plasma).
