The process in which the antigen major histocompatibility complex MHC protein compound is inserted into a body cell s plasma membrane. A The voltage change in the atria is minimal and therefore does not register on an ECG. The electrocardiograph measures the strength of the myocardial contraction.

Asked Aug 27 2019 in Health Biomechanics by cbvet85.
