Answer:

FIRST OF ALL ITS HEART

The human heart is a four-chambered muscular organ, shaped and sized roughly like a man's closed fist with two-thirds of the mass to the left of midline. The heart is enclosed in a pericardial sac that is lined with the parietal layers of a serous membrane.                                                                      MARK ME BRAINLIEST
