Answer:

The first part of the small intestine is called duodenum

Explanation:

The small intestine is a tightly folded tube which connects to the stomach on the top end and to the large intestine on the bottom end.

The small intestine consists of three parts:

duodenum

jejunum (absorbs sugars, amino acids, and fatty acids)

ileum (absorbs remaining nutrients that did not get absorbed by the duodenum or jejunum)

Duodenum is responsible for completing the first phase of digestion. In this section of the intestine, food is mixed with enzymes and bile which help break down food.

Two differences between hormones and the nervous system

leva [86]

Answer:

Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.
