Answer:
Observation of the internal structure of mammalian heart.
Material required: Soda straws, a sharp and long blade/scalpel, a tray and jug of water, dissection scissors, and foreceps, all freshly gathered from the butcher.
Explanation:
Procedure
- Wash the heart thoroughly to ensure that all of the blood has been drained from the chambers.
- Take the soda straws and place them in the blood vessel stamps.
- Look at how the blood arteries on the heart's wall are arranged.
- Maintain the heart in the tray with a broad arch-like tube facing upwards. This is the ventral side of the body.
- Examine the thickness of the heart's wall, the number of chambers, the size of the chambers, the differences between the chambers, and the connections between chambers.
- In the lower region of the heart, you can see white coloured structures. Take note of their size, form, and where they are joined.
