Answer and Explanation:

The sympathetic nervous system prepares the body for vigorous physical activity and is often referred to as the fight-or-flight. The parasympathetic nervous system relaxes the body and inhibits many high energy functions and is often referred to as rest and digest. Parasympathetic system is one of several excitatory pathways during arousal. The excitatory signals can originate in the brain, either by the sight or thought of an appealing sexual partner. Arousal is an example of parasympathetic system.

During flight and fight, the liver can be stimulated to release glucose into the bloodstream providing more energy that will be ready to power the muscles.

Question: Why is the countercurrent system of flow important for fishes?

Explanation and answer: Fishes use a design called 'countercurrent oxygen exchange' to maximize the amount of oxygen that their blood can pick up. They achieve this by maximizing the amount of time their blood is exposed to water that has a higher oxygen level, even as the blood takes on more oxygen.
