The RV infundibulum is the specialized region of the right ventricle that leads to the pulmonary artery and pulmonary trunk.
The term "RV infundibulum" refers to a crucial anatomical structure within the heart's right ventricle. According to the provided reference, the infundibulum is the entrance from the right ventricle into the pulmonary artery and pulmonary trunk.
Understanding the RV Infundibulum
This specific part of the right ventricle acts as an outflow tract, directing deoxygenated blood towards the lungs for oxygenation.
- Location: Situated superiorly and anteriorly within the right ventricle.
- Function: Serves as the final passageway for blood exiting the right ventricle before entering the pulmonary circulation.
- Structure: The wall of the infundibulum is notably smooth, in contrast to the trabeculated (muscular ridges) walls found in the main body of the right ventricle. This smooth structure facilitates efficient blood flow out of the ventricle.
Key Characteristics
Let's summarize the main points about the RV infundibulum:
| Characteristic | Description |
|---|---|
| Location | Within the right ventricle |
| Function | Entrance to pulmonary artery and pulmonary trunk |
| Structure | Smooth-walled |
| Role | Right ventricular outflow tract |
This smooth, funnel-shaped region plays a vital role in the heart's pumping action, ensuring blood is effectively propelled into the pulmonary circuit.
