Collin often experiences a runner's high during his daily 3-mile run. This is most likely produced by neurotransmitters in his brain called endorphins.

Endorphins: They are the neurotransmitters or peptide hormones released in the brain and nervous system when exposed to some stress or intensive exercises.

They are often released in the brain to help relieve pain, reduce stress, and improve the sense of well-being. They are the kind of neurotransmitters that attach to opioid receptors in the brain and carry signals across the nervous system. They work by blocking the nerve cells that receive the pain signals.

People often feel a "runner's high" after a long run. Other forms of exercise can also help you to release endorphins and relieve pain. These include swimming, dancing, hiking, power walking, massage, etc.

To know more about endorphins, refer to the following link:

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
jekas [21]

The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.

<h3>What is Active transport?</h3>

Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.

During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.

But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

The complete question is as follows:

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?

  • Lungs
  • Stomach
  • Small intestine
  • Liver

Therefore, the correct option for this question is C, i.e. small intestine.
