Alveolar walls are thin to enable the quick passage of oxygen in and out of the lungs. The lungs works hand-in-hand with the heart and also is responsible in converting blood that's de-oxygenated into an oxygenated blood that is usable by the organ systems of the body. The alveolar walls are also designed to have thin membranes so that it can expand and constrict quickly allowing us to breather properly.
Answer:
<u>Motor neurons </u>send messages to the muscles and glands to respond to stimuli.
<u>Sensory neurons </u>move information towards the central nervous system for processing.
<u>Interneurons </u>carry information from one type of neuron to another.
Explanation:
- Neurons are basic structural and functional units of Nervous system.
- Neurons possess electrical excitability, the ability to respond to a stimulus and convert it into a action potential.
- Neurons can be classified on the basis of their structure and function.
- On the basis of structure neurons are classified as, Multipolar neuron;Bipolar neuron; Unipolar neuron.
- On the basis of function neurons are classified as, Afferent or sensory neuron; Efferent or motor neurons; Interneurons or association neurons.
