A different tissue results from a collection of each type of cell.
More time was spent creating the neuron.
Answer:
Nerve cell shapes vary according to the number, branching and disposition of their projections or dendrites, collectively known as arborization. This determines their capacity for interacting with their environment and with other nerve cells or neurons, hence their computational ability and roles.

Before food is delivered into the intestine, it is mechanically distributed and stored in the stomach as a temporary container.
Carbohydrates are chemically digested in the stomach. Since the stomach only makes protease and lipase (pepsin breaks down proteins into peptides),
it is unable to chemically digest carbohydrate (gastric lipase that digests lipids into glycerides).
Therefore, Stomach is digestive organ in human
