Skeleton of the Heart – Function and Importance

The Skeleton of the Heart consists of fibrous tissue and creates the central support of the heart. It is composed of fibrous rings that surround the atrioventricular, pulmonary, and aortic orifices. These rings provide circular form and rigidity to the atrioventricular orifices and roots of the aorta

Hemostasis – The Sequence of Events That Occurs During Hemostasis.

Whenever blood vessels are damaged, the loss of blood poses a considerable threat to homeostasis. Hemostasis is a positive-feedback mechanism initiated after vascular injury to stop or limit blood loss. There are three separate but interrelated processes involved in hemostasis: vascular spasm, platelet plug formation, and coagulation.

Pulmonary Circulation

The lungs receive the entire output of the right ventricle. Consequently, pulmonary blood flow is equal to cardiac output, about 5 L/min. The normal transit time for blood through the pulmonary capillaries is about 0.75 seconds. Gas equilibration between the alveolar air and the pulmonary capillary takes

Variations in the Coronary Arteries/ Coronary Dominance

The origin, course, and distribution of the posterior interventricular artery are variable. In right coronary dominance, the posterior interventricular artery is a branch of the right coronary artery. It’s seen in 90% of the individuals. In left coronary dominance, the posterior interventricular artery originates from circumflex branch

Fibrinolysis and Anticoagulants

The ability to create clots to limit blood loss from sites of vascular injury is balanced by systems designed to limit clot formation and to dissolve existing clots. The blood contains natural anticoagulants that act continuously to inhibit clot formation. Fibrinolytic agents dissolve existing clots. In doing
