13 kwi 2024 · The aorta carries oxygenated blood to major arteries that supply the body (and heart itself). Most diagrams indicated deoxygenated blood in blue and oxygenated blood in red. This makes the flow of blood easier to understand, but keep in mind even deoxygenated blood is actually red.
24 lut 2021 · Function and anatomy of the heart made easy using labeled diagrams of cardiac structures and blood flow through the atria, ventricles, valves, aorta, pulmonary arteries veins, superior inferior vena cava, and chambers.
3 lis 2023 · Blood flows from the atria into the ventricles through the atrioventricular orifices (right and left)–openings in the atrioventricular septa. These openings are periodically shut and open by the heart valves , depending on the phase of the heart cycle .
The diagram illustrating the blood flow through the heart shows the various chambers and valves that ensure efficient circulation. The heart consists of four chambers: two atria (left and right) and two ventricles (left and right). The atria receive deoxygenated blood, while the ventricles pump oxygenated blood out to the body.
This diagram showcases the heart through the orientation of the frontal plane. The figure is labeled to showcase the heart’s basic anatomical structures, including; right and left atria and ventricles, and the aorta.
Learning Objectives. By the end of this section, you will be able to: Describe the location and position of the heart within the body cavity. Describe the internal and external anatomy of the heart. Identify the tissue layers of the heart. Relate the structure of the heart to its function as a pump.
Myocardium. The myocardium is the muscular middle layer of the heart wall that contains the cardiac muscle tissue. Myocardium makes up the majority of the thickness and mass of the heart wall and is the part of the heart responsible for pumping blood. Below the myocardium is the thin endocardium layer. Endocardium.
