Basically your superior and inferior viena cava carry the blood to the heart…then it goes to the right atrium…from there it goes thru the tricuspid valve and then to the right ventricle, from there it goes thru the pulmonary valve then into the pulmonary artery and into the lungs and then to the alveolar sacks where the blood gets oxygenated… then back to the pulmonary vein and into the left atrium then thru the mighty mitral valve then to the left ventricle… then thru the aortic valve to the aorta then to arterioles then to the systemic capillaries…ultimately it can end where ever u want it to… big toe, tonsil, etc…
Blood goes in this order... Right Atrium -> Right Ventricle -> Lungs -> Left Atrium -> Left Ventricle -> Ascending Aorta -> Descending Aorta. So neither pump blood to the the Left Ventricle but the Left Ventricle pumps blood to the ascending aorta.
Heart receive the blood from ascending aorta. You get right and left coronary arteries from the aorta, to supply blood and nutrients to your heart.
When leaving the right ventricle during systole the blood leaves through the pulmonic semilunar valves, into the pulmonary trunk and out the right and left pulmonary arteries...heading to the lungs.
Left coronary artery.
Ascending Aorta-->Arch of the Aorta--> Brachiocephalic Trunk--> Left Subclavian Artery--> Left Axillary Artery--> Left Brachial Artery--> Left Radial-Ulnar-Palmer Arteries . How is the flow of blood different to the right arm? Merely exchange the "left" with "right" :) Reference: A & P ll Blood Vessels
After blood leaves the left ventricle, it goes through the aortic valve to be pumped throughout the body.
Aorta
Right and left coronary arteries.
the right auricle
The right coronary artery takes its blood supply from the right coronary sinus, just above the aortic valve and sprouting from the ascending aorta. The left coronary artery takes its blood supply from the left coronoray sinus, also coming off of the ascending aorta. From these main coronary arteries, the rest of the branch coronary arteries are derived.
