In humans there are two main systems for carrying messages from one part of the body to another: the nervous system and the blood.
Nerve cells (neurons) carry rapid impulses to precise locations. Every time a muscle contracts it is the result of a message arriving from a nerve cell; nerves stimulate some glands, too, for example the sweat glands in the skin.
The blood circulates continuously, and in it will be any hormones that have been secreted by endocrine(hormone-producing) glands. The message, in the form of the hormone, travels much more slowly than a nerve impulse, but the effect is much longer-lasting.
Apart from endocrine messaging, there are two other, more local, systems:
* paracrine: this system of signaling involves compounds being secreted by a cell and traveling a short distance to exert an effect on other cells nearby. A good example of this is the release of neurotransmitters (such as acetylcholine) to bridge the gap (synapse) between two neurons. * autocrine: this term refers to the release by a cell of a compound that has an effect on that same cell (hence "auto-"). The signal compound may leave the cell and stimulate a receptor embedded in the cell membrane, as if it were a chemical from another cell, or it may remain within the cell, simply carrying a message from one part of the cell to another.
The brain sends signals to the spinal cord, which distributes those signals throughout the neural network - a network of neurons - which then carries signals to parts of the body such as the muscles, skin, lungs, etc.
Signals are sent back to the brain in reverse order.
If you're asking what cells carry these messages, then your answer is efferent neurons.
Afferent neurons carry signals from the peripheral nervous system to the central nervous system (spine and brain) where they interface with interneurons, which process the information they receive from the afferent neurons. The interneurons then send a response through the efferent neurons to the relevant body parts.
Majorly nervous sysytem- as there are bio chemal elements present onour nervous system which are known as neurons they carry messages from one body part to another.
The nervous system
peripheral nervous system
rthe nerves
The brain controls every part of your body, it also sends messeges to the nerves to say somethings hurts, tickles, or iches, or any feeling you can get.
your nervous system sends messages to the brain like when you move your arm you nervous system sends the message to the brain
Hormone.
digestive system
The cardiovascular system sends oxygen rich blood through out the body.

Body
the heart it works the body like blood but the brain sends messeges to the heart to beat didint you learn anything in third grade
Q:what body system sends electrical signals to all other body systems well the answer is nervous system yea that is it

The brain sends them a message.
i think the brain sends messages between different parts of the body.
The nervous system is the central control that sends nerve signals throughout the body for other systems to regulate.
