Most chemical digestion and absorption of nutrients takes place in the _small intestine_.
All macronutrient (protein, carbohydrate, fat) breakdown into their basic subunits (monomers) is finalized in the small intestine. This is where all foodstuffs will meet the last set of enzymes and emolients/emulsifiers (dissolvers) to do the final breaking of bonds (chemical digestion). And it is therefore also in the small intestine that a vast blood supply allows a special circulatory route to absorb (pick up) these nutrients (sugars, amino acids, small fatty acids) via their tiny capillaries, and transport them to the liver for processing. This circuit is known as the Portal Venous System.

Explanation:
Answer:
<u>True</u>
Explanation:
There are <u>two components of efferent/motor nervous system</u>.
1.<u>Autonomic Nervous System</u>
It innervates the<u> smooth muscles, glands and cardiac muscles and is under involuntary control. ANS is further divided into Sympathetic nervous system and parasympathetic nervous system.</u>
It is composed of<u> preganglionic neurons</u> and <u>postganglionic neurons</u>. <u>The axons of preganglionic neurons synapse on the cell bodies of postganglionic neurons. </u>
Autonomic ganglia of sympathetic nervous system form the paravertebral ganglia (long chains on either side of spinal cord) and autonomic ganglia of parasympathetic nervous system are located close to the organ which the fibers innervate.
<u>2. Somatic Nervous system</u>
It is responsible for<u> voluntary control of skeletal muscles and is composed of motor nerve and the innervated muscle.</u>
