Dissection
This week in Biology, students worked in pairs to dissect various organs. Mr Hough`s and Mr Russ`s classes -10C3 and 10W4 - identified the cortex and the medulla in lamb kidneys. They were able to see where the blood vessels and ureter entered and exited . 9CE and 9CG dissected chicken hearts under the supervision of Miss Spurrier and Mr Russ, as a visual tool to discuss the functions of the atria and ventricles . 9W2, 9C1 and 9WE were treated to Mr Rose demonstrating the dissection of an Ox heart. The students applied this knowledge when they opened the chicken hearts and threaded strings through the blood vessels. The size comparison of the two hearts amazed the students , no surprise when a chicken heart is about 3 cm in length, whereas the ox heart is the size of a human head.
