Hello, I'm a medical professional with a strong background in anatomy and physiology. When examining the heart, identifying its ventral side is crucial for understanding its structure and function. Here's how you can determine the ventral side of the heart:
1. Positioning: The heart is located in the thoracic cavity, slightly to the left and central. The ventral side is the one that faces forward and downward when the heart is in its normal anatomical position.
2. Surface Anatomy: The ventral surface of the heart is also known as the diaphragmatic surface because it's the side that's closest to the diaphragm.
3. Great Vessels: On the ventral side, you'll find the pulmonary trunk, which is the large vessel that carries deoxygenated blood from the heart to the lungs, and the vena cavae, the large veins that return oxygenated blood from the body to the heart.
4. Auricles: The right atrium's auricle is typically on the dorsal side, but a part of it may extend to the ventral side, which can be a distinguishing feature.
5. Coronary Circulation: The coronary arteries, which supply blood to the heart muscle, have a distribution pattern that can help identify the ventral side.

Place the heart in the dissecting pan so that the front or ventral side is towards you (the major blood vessels are on the top and the apex is down). The front of the heart is recognized by a groove that extends from the right side of the broad end of the heart diagonally to a point above & to your left of the apex.read more >>
