In the context of hemostasis, which formed elements are the smallest components found in blood?
A
Neutrophils
B
Monocytes
C
Platelets (thrombocytes)
D
Erythrocytes (red blood cells)
Verified step by step guidance1
Step 1: Understand the context of hemostasis, which is the process that stops bleeding by forming clots in blood vessels.
Step 2: Identify the formed elements in blood, which include erythrocytes (red blood cells), leukocytes (white blood cells such as neutrophils and monocytes), and platelets (thrombocytes).
Step 3: Recall the relative sizes of these formed elements: erythrocytes are larger than platelets, and leukocytes (neutrophils and monocytes) are generally larger than erythrocytes.
Step 4: Recognize that platelets are small cell fragments, not full cells, and are the smallest formed elements in blood involved in hemostasis.
Step 5: Conclude that among the options given, platelets (thrombocytes) are the smallest formed elements found in blood, playing a key role in clot formation.
