Tigers cannot regenerate their body parts.
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).
All body systems are controlled by the brain.
Every body system is affected by every other body system.
God did it no body knows or do they
Their mouths.
All the systems of the body work together; there are no isolated systems.
Tigers suffer from loss of habitat, and poachers take them for body parts.
The link between all body systems is the brain. The brain regulates all of the body systems using a variety of hormones and signals.
