ANATOMY

Detailed explanation-1: -The coronary circuit: Coronary refers to your heart’s arteries. This circuit provides the heart muscle with oxygenated blood. The coronary circuit then returns oxygen-poor blood to the heart’s right upper chamber (atrium) to send to the lungs for oxygen.

Detailed explanation-2: -Arteries carry blood away from the heart and veins carry blood back to the heart.

Detailed explanation-3: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.

Detailed explanation-4: -The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.

Detailed explanation-5: -Your circulatory system, also known as your cardiovascular system, is made up of your heart and blood vessels. It works to transport oxygen and other nutrients to all the organs and tissues in your body.
