   • Location of the Heart. The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. Figure 19.2 shows the position of the heart within the thoracic cavity.
   • Shape and Size of the Heart. The shape of the heart is similar to a pinecone, rather broad at the superior surface and tapering to the apex (see Figure 19.2).
   • Chambers and Circulation through the Heart. The human heart consists of four chambers: The left side and the right side each have one atrium and one ventricle.
   • Membranes, Surface Features, and Layers. Our exploration of more in-depth heart structures begins by examining the membrane that surrounds the heart, the prominent surface features of the heart, and the layers that form the wall of the heart.

   Aug 17, 2023 · In the anatomical position, the left atrium is concealed behind the right atrium, as the latter contributes to most of the upper part of the sternocostal surface of the heart. The interatrial groove (which is the surface marking for the atrial septum ) serves as a landmark that separates the atria on the surface of the heart.

   Jun 11, 2024 · The heart is the pump that moves blood around your body. It has four main parts: two upper chambers called atria and two lower chambers called ventricles. These parts work together to get oxygen-rich blood to your body and oxygen-poor blood back to your heart.

   3 days ago · The anterior tibial vein forms a small network anterior to the tibia and collects blood from the tissues of the shin. The plantar venous arch sends its blood into the leg through the medial and lateral plantar veins into the posterior tibial vein, which ascends along the leg posterior to the tibia.

   Long bones are found in the upper limbs (humerus, ulna, radius) and lower limbs (femur, tibia, fibula), as well as in the hands (metacarpals, phalanges) and feet (metatarsals, phalanges). Long bones function as rigid bars that move when muscles contract.

   What is the function of the atria & ventricles?

   • Each of the upper chambers, the right atrium (plural = atria) and the left atrium, acts as a receiving chamber and contracts to push blood into the lower chambers, the right ventricle and the left ventricle. The ventricles serve as the primary pumping chambers of the heart, propelling blood to the lungs or to the rest of the body.

   Which artery supplies blood to the left side of the heart?

   • Left coronary artery: This artery supplies blood to the left side of the heart, including the left ventricle and left atrium. It also divides into the left anterior descending artery (to supply blood to the front of the left side of the heart) and the circumflex artery (to supply blood to the outer region and back of the heart.

   Where is the left atrium located?

   • In the anatomical position, the left atrium is located between the 5th to 8th thoracic vertebrae if the individual is supine (lying flat) or the 6th to 9th vertebrae in someone who is standing erect. Also posteriorly related to the left atrium are the descending aorta, esophagus, and the previously described pulmonary veins.

   What is the opening between the left atrium and the ventricle?

   • The opening between the left atrium and ventricle is guarded by the mitral valve. Recall that, although both sides of the heart will pump the same amount of blood, the muscular layer is much thicker in the left ventricle compared to the right (see Figure 19.8).
