1: Left coronary artery

2:Right coronary artery

3:cardiac veins

4:coronary sinus

5:brachiocephalic trunk

6:left common carotid artery

7: Interatrial septum

B) For each chamber of the heart where does it deliver blood during systole, where it receives blood during diastole

Answer 1

1. Left coronary artery - Arises from the aorta and sends blood to left side of the heart (Left ventricle) and supplies oxygenated blood

2) Right coronary artery: Arises from the aorts and sends blood to right side of heart (Right atrium and right ventricle) and supplies oxygenated blood

3) cardiac veins- it gets blood from left marginal vein and left posterior ventricular vein and gives to coronary sinus .It carries deoxygenated blood

4) Coronary sinus - It gets blood from cardiac veins and sends blood into the right atrium . It carries deoxygenated blood

5) Brachiocephalic trunk - It gets blood from aortic arch and sends to right subclavian artery and right common carotid artery and carries oxygenated blood
