Our Year 12 Biology students have been working hard in the laboratory to apply the knowledge they are acquiring in the classroom.
As part of this process, they dissected a pig’s heart to identify its parts and understand their functions, as they are currently studying topics related to the circulatory system and coronary disease, specifically focusing on how arteries that supply blood to the heart can become blocked.
Through this practical activity, they were able to observe:
- The external anatomy of the heart, identifying the atria and ventricles, as well as the blood vessels that enter (vena cava and pulmonary vein) and exit the heart (pulmonary artery and aorta), in addition to the main vessels supplying blood to the heart itself (coronary arteries).
- Following the dissection, they were able to study the internal anatomy: the valves, the ligaments that support them, and a comparison of the wall thickness of both ventricles, noting to which part of the body they pump blood and how their anatomy facilitates this function.
