Lobsters possess several body systems, including the muscular system, which aids in movement, and the exoskeletal system, providing structure and protection. They have a circulatory system that is open, relying on hemolymph to transport nutrients and oxygen. Additionally, their digestive system processes food, while the nervous system coordinates their movements and responses to the environment. Lastly, lobsters have a respiratory system that utilizes gills to extract oxygen from water.

The only part of the lobster that is edible is the tail. The body and head are wasted.
There are a few ways, you can deep freeze the Lobster, this puts the Lobster to sleep and shuts down its systems so when you 'kill' it will not feel a thing or you can place the Lobster in a large pot of cold water then bring the water to the boil, this puts the Lobster to sleep and a painless death follows. Some drop the Lobster into rapidly boiling water the Lobster dies instantly.
Lobsters have 20 segments.

Your body is the sum of all its systems. There are no "other systems". All the body's systems have to be working together or the body will not be able to stay alive.
Body systems work together to keep the body healthy and the body systems are interdependent (they rely on each other).
