Answer:
Blood is a fluid that is technically considered a connective tissue. It is an extracellular matrix in which blood cells are suspended in plasma. It normally has a pH of about 7.4 and is slightly denser and more viscous than water.

pH of 7.0 is not normally maintained by blood.
Blood:
- White blood cells (leukocytes) ,platelets (thrombocytes), red blood cells (erythrocytes) and plasma (the liquid portion of the blood) are the normal constituents of blood.
- It can be evaluated in a hematology lab using an automated analyzer the amount of each of the formed elements (erythrocytes, leukocytes and platelets).
- Between 7.35 and 7.45 (slightly alkaline) the pH of blood is tightly controlled.
- Salty because of dissolved electrolytes in the plasma.
