(a)
Leukocytes, erythrocytes, and thrombocytes make up this part of the blood:
The formed elements
The plasma
The dissolved substances
The antigens
When a blood vessel is injured, the muscular tissue in the middle layer of the blood vessel constricts to limit blood flow. This is called
Primary hemostasis
Secondary hemostasis
Vasoconstriction
Fibrinolysis
A centrifuged specimen that contains an anticoagulant has a buffy coat, which contains
