We have been dissecting lamb hearts as part of our 'Healthy Bodies, Strong Minds' Inquiry unit. Then we had to write our observations as we cut into the heart and explored the interior.
Tijuana:
General description:
Size- 13.5 cm / Clenched Fist
Shape- Big Slug
Colour- Maroon with white patches
Texture- Surface is slimy and smooth
Some parts look rough
Smell- Meat
The heart is just the size of a clenched fist, but I also measured it and it was 13.5 centimeters. Inside is basically just red and white patches, the red parts are just muscles and the white patches are fat. If you go close to it, it only smells like meat.
As you are cutting open the heart you are cutting a thick muscular wall of the heart. When you touch the inside of the lambs heart the major blood vessels are strong but smooth and have a creamy colour.
If you cut open the lamb heart inside are ligaments inside the ventricles that look like spider webs. They look really thin but they are really strong and hard to break, and it helps contract the muscles during heart beat.Their colour is white.
