Document Summary
Moves blood through the blood vessels, regulating amount of blood flowing to tissues and blood pressure. Functional in the embryo by day 25. Location = thoracic cavity, mediastinum (medial cavity of the chest), apex of the heart touches diaphragm, major vessels emerge from base of the heart. Grooves (sulci) on the surface of the heart contain the major blood vessels for the heart and serve as landmarks. On the anterior and posterior surface there are the anterior and posterior interventricular sulci (mark where the interventricular septum is) and between each atrium and its ventricle there is an atrioventricular sulcus. Pumps into two separate circulatory routes right side pumps blood into pulmonary circulation (carries deoxygenated blood to lungs to get oxygen) and left pumps into systemic circulation (carries oxygenated blood to body) The heart lies inside the double-walled pericardial sac or pericardium.
