A)
neutrophils.
B)
erythrocytes.
C)
albumin.
D)
basophils.
Ans:
A
Feedback:
Neutrophils are very mobile and are the first cells to go to an area of tissue damage. Erythrocytes (RBCs) contain an O2-carrying protein that functions in the transport of oxygen. Albumin, a plasma protein, does not pass through the pores in the capillary wall to enter the interstitial fluid and therefore contributes to the plasma osmotic pressure and maintenance of blood volume. Basophil granules contain heparin, an anticoagulant; histamine, a vasodilator; and other mediators of inflammation.
