Firstly, to summarise the whole chapter 8 – Transport in Human. It is about the transfer of substances from one part of the body to another through a transport system. This occurs due to the complex multi-cellular system, where numerous cells are situated deep in the body. Hence simple diffusion or osmosis cannot transport substances to and fro.

The first part of the experiment as stated above is to identify parts of the heart externally, such as anterior vena cava, aortic arch, pulmonary arch, pulmonary artery, pulmonary vein, left atrium, right atrium & etc. and internally, identifying the blood vessels, white and red blood cells, understanding the structures of the blood vessels and its function and describe the structures of blood vessels, red and white blood cells.

As shown above, Benjamin has labelled the part of the heart structure that he identified with the pins given as instructed.
Firstly, we differentiated the left and right atrium of the heart and poke the other parts with a glass rod to identify the rest of the parts of the heart.
