Question 7

what organ releases erythropoietin?

Answer 7

kidney

Question 22

Neutrophils

Answer 22

bacteria slayers (WBC)

Question 23

Lymphocytes

Answer 23

immunity
Tcells: act directly on virus-infected cells or tumor cells
Bcells: product anitbodies
Natural killer cells: non specific defense

Question 24

Monocytes

Answer 24

mature into macrophage, eat bacteria, dead cells and cellular debris

Question 25

Eosinophils

Answer 25

attack parasitic worms, lessen severity of allergies

Question 26

Basophils

Answer 26

promote inflammation

Question 27

Platelets (thrombocytes)

Answer 27

used for clotting, regulated by thrombopoeitin

Question 28

anemia

Answer 28

a decrease in the total amount of hemoglobin in the blood (generally less than 13.5 g / dL in males and 12.5 g / dL in females), which results in reduced carrying capacity for oxygen.
