The work in this paper presents an analytical study of nanoscale communication networks operating in-vivo at the Terahertz frequency. The paper discusses the path loss of a proposed simplified human tissue model within a wireless body area network (WBAN). The human model is simplified to include water, whole blood and skin. The main objective is to assess the losses induced by water molecules. The simulation is done using the numerical values of the loss parameters measured in literature. The simulation results indicate that the path loss at 1 THz for a distance of 1 mm depth is 32 dB for water, 33 dB for whole blood and 34 dB for skin. The results for whole blood and skin are in line with the results encountered in literature. On the other hand, the results of water molecules are similar to that of whole blood. This finding verifies that the electromagnetic communication inside the human body is a valid analytical assumption for the in-vivo modeling of nano-communications in the THz band taking into consideration that the human body is mainly build of water.
