Solution
The correct option is D Neurons and glia The nervous system is made up of neurons - specialized cells that can receive and transmit chemical or electrical signals and glia - cells that provide support for the neurons. A neuron can be compared to an electrical wire. It transmits a signal from one place to another.
Glia can be compared to the workers at the electric company who make sure wires go to the right places, maintain the wires, and take down wires that are broken. Alveoli and bronchioles are the part of the respiratory system, nephrons is a part of the excretory system.
