Which of the following is an incorrect statement?
Options
- ABlood group ' O ' person have A and B antigens on RBCs.
- BEosinophils resist infections and are associated with allergic infection.
- CRBC's contain carbonic anhydrase.
- DT wave of normal ECG represent of depolarization of ventricle.
Correct answer
D. T wave of normal ECG represent of depolarization of ventricle.
Step-by-step solution
The T wave represents the repolarization (or recovery) of the ventricles. The end of the T-wave marks the end of systole. The P -wave represents the electrical excitation (or depolarisation) of the atria, which leads to the contraction of both the atria. The QRS complex represents the depolarisation of the ventricles, which initiates the ventricular contraction.
