.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

Functions of Circulatory System
Rh factor
Aortic Loops
Erthrocytes (red blood cells RBC)
19. Universal recipient as it has neither anti-A nor anti-B antibodies

White Blood Cells (WBC)
Active Immunity
Pores
Atrioventricular (AV) Node
24. Fetal red blood cells (which will have the Rh factor) enter maternal circulation during birth which cause the anti-Rh antibodies she produced when sensitized by the first birth may cross the placenta and destroy fetal red blood cells
Left Side of Heart
Lymph

Vaccination
Arterioles
Apical Meristem
26. Modifies the rate of heart contraction
Mechanism and Control
