Structural and functional features of each cardiac chamber
Internal anatomy of the right ventricle
The right ventricle is a vital cardiac chamber responsible for pulmonary circulation. Its anatomical features include trabeculae carneae, papillary muscles, and the infundibulum, all ensuring efficient blood flow.
Structural and Functional Features of Each Cardiac Chamber
Internal Anatomy of the Right Ventricle
The right ventricle plays a crucial role in pulmonary circulation, propelling deoxygenated blood to the lungs for gas exchange. Anatomically, it has several distinguishing features:
1. Shape and Location
The right ventricle is roughly triangular in shape and situated anteriorly in the heart, wrapping around the left ventricle.
2. Trabeculae Carneae
Muscular ridges present on the inner surface, improving contractility and structural integrity.
3. Papillary Muscles and Chordae Tendineae
These structures attach to the tricuspid valve leaflets, preventing regurgitation during ventricular contraction.
4. Outflow Tract
The infundibulum, or conus arteriosus, leads to the pulmonary valve and artery, ensuring efficient blood ejection.
Understanding the right ventricle’s anatomy aids in diagnosing and managing cardiovascular disorders effectively.
