Flowchart Of The Heart
Two ventricles each of which is a muscular chamber that squeezes blood out of the heart and into the blood vessels and two atria each of which is a muscular chamber that drains and then squeezes blood into the ventricles.
Flowchart of the heart. Suggested by sme bonnie tyler total eclipse of the heart video song total eclipse of the heart. The superior vena cava svc and the inferior vena cava ivc see figure 3. The two atria reside at the top of the heart. Blood flow through the heart.
The ventricles pump blood out of the heart. Blood flow all blood enters the right side of the heart through two veins. The heart is a complex organ using four chambers four valves and multiple blood vessels to provide blood to the body blood flow itself is equally complex involving a cyclic series of steps that move blood trough the heart and to the lungs to be oxygenated deliver it throughout the body then bring blood back to the heart to re start the process. The atria receive blood returning to the heart.
The human heart has four chambers. The right atrium receives deoxygenated blood through the superior and inferior vena cavas from the body and pumps it to the right ventricle through the tricuspid valve which opens to allow the blood flow through and closes to prevent blood backing up the atrium. The svc collects blood from the upper half of the body. The heart is located under the rib cage to the left of your breastbone sternum and between your lungs.
Continued looking at the outside of the heart you can see that the heart is made of muscle. Superior and inferior vena cavae and the coronary sinus. The atria are the top two chambers of the heart that receive incoming blood from the body. The two ventricles are at the bottom.
The chambers are separated by valves that prevent the backflow of blood as it moves through the heart. Normal heart anatomy and physiology need the atria and ventricles to work sequentially contracting and relaxing to pump blood out of the heart and then to let the chambers refill. Beginning with the superior and inferior vena cavae and the coronary sinus the flowchart below summarizes the flow of blood through the heart including all arteries veins and valves that are passed along the way. Webmd s heart anatomy page provides a detailed image of the heart and provides information on heart conditions tests and treatments.
