This unidirectional flow of blood through the heart shows that mammals have a double circulatory system. This means blood travels through the heart twice in one circulation of the body Blood Flow Through the Heart. The human heart is primarily comprised of four chambers. The two upper chambers are called the atria, the remaining two lower 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 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 Illustrations of Blood Flow to the Heart. Location and size of the heart. The heart is located under the rib cage -- 2/3 of it is to the left of your breastbone (sternum) - 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 Your heart has four separate chambers. You have two chambers on the top (atrium, plural atria) and two on the bottom (ventricles), one on each side of your heart. Right atrium: Two large veins deliver oxygen-poor blood to your right atrium. The superior vena cava carries blood from your upper body In this Higher Human Biology revision guide, you will learn in detail that cardiac output is a measure of the rate of blood flow through the heart and its associated blood vessels.

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 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.

Location and size of the heart. The heart is located under the rib cage -- 2/3 of it is to the left of your breastbone (sternum) -- and between your lungs and above the diaphragm. The heart is about the size of a closed fist, weighs about ounces, and is somewhat cone-shaped
