Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) ...
How the heart works circulatory system?
The right ventricle pumps the low-oxygen blood to the lungs to pick up a fresh supply of oxygen. The left atrium receives to high-oxygen blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the high-oxygen blood to the rest of the body.
How does the circulatory system start?
The circulatory system begins in your right atrium, the upper right-hand chamber of your heart. Blood moves from the right side of your heart through your lungs to get rid of carbon dioxide and pick up oxygen, and then returns to the left side of your heart, ending up in the left ventricle.
What system works with the circulatory system?
respiratory systemYour respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs.

This continuous flow is necessary because there is a constant exchange of oxygen and nutrients happening in the capillary walls. No cell in the body is far from a capillary.
What system is blood in?
Blood is circulated throughout your body via your arterial system — arteries, arterioles, and capillaries —and returned to your heart via the venous system—veins and venules. Your blood is vital to your well-being and circulates nutrients including electrolytes, oxygen, carbon dioxide and amino acids throughout your body.
How does blood travel through the aorta?
Your blood travels from your aorta through a series of smaller blood vessels until it reaches your capillaries. Before reaching your capillaries, however, blood must travel through the arterioles, where its speed and pressure are constantly adjusted as different segments of the arterioles change diameter in response to pressure and chemical sensors positioned nearby. These sensors adjust blood flow via the arterioles in response to changing conditions in your body.
Which chamber of the heart is responsible for circulating blood?
When it comes to circulating blood throughout your body, the left ventricle is the most important chamber in the heart. The left ventricle is the largest of the four chambers and is responsible for generating the force necessary to propel your blood out of your aorta, the first artery your blood enters as it leaves your heart.
Which chamber of the heart is the left ventricle?
As blood moves through your heart, it passes through each of the four chambers (upper right, lower right, upper left, lower left), takes a quick detour to the lungs to get rid of carbon dioxide and pick up oxygen, and ends up in the lower left-hand chamber, called the left ventricle.
What is the blood circulatory system?
