The transport layer segments data whenever the size of the packet is too large to transport efficiently--in practice, this happens whenever the data is too large to fit in a single network layer packet. Although the network layer can also fragment packets, the process is inefficient and generally the transport layer segment size is adjusted so that no further division is required in the network layer.
Much more details are here:

transport layer processes occur between the applicaitoin layer and internet layer of the TCP/IP and between the session layer and network layer of the OSI model.
A transport layer is the backbone of TCP/IP and the Internet. In this day and age, there are not design flaws in the system. The design of transport layer incorporates data stream with transmission.
Segmentation of data happens at transport layer. Because transport layer is responsible for successful transportation of data through out the network.
The Transport layer (layer 4) handles segmentation and reassembly of the data.

the smooth muscles are responsible for perstalsis and segmentation, so that means its the muscularis externa. :)
