Quizplus · Accepted Answer

Actin and myosin form cross-bridges,allowing myocardial contraction to take place.Z-disk,A-band,I-band,and M-band are all portions of the sarcomere functional unit to promote contraction in the heart.Renin converts the protein angiotensinogen to angiotensin I.When angiotensin I passes through the pulmonary vascular bed,it is activated by angiotensin-converting enzyme to become angiotensin II.
