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.

Answer:
The blood goes through an oxygenation process that is carried out by the blood vessels, the heart and the lungs, so if any of these structures is affected the entire circulation system will be altered. The circulatory system is made up of two circulatory systems: the pulmonary that provides oxygen to the blood and the systemic that carries it to all the tissues of the body
Explanation:
The veins transport the deoxygenated blood to the heart pumps this blood back to the lungs, where it absorbs more oxygen. This oxygenated blood returns to the left side of the heart, which pumps it to the rest of the body through the arteries. Pulmonary circulation is a process in which the lungs, heart, veins and pulmonary arteries intervene, with the aim of oxygenate the blood.This system begins in the left ventricle of the heart, since this is the chamber through which it exits deoxygenated blood that has already fulfilled its function in all tissues of the body, to later reach the lungs through the blood vessels in the region.Systemic circulation is a long process that involves the chambers of the heart and blood vessels throughout the body, with the aim of carrying oxygenated blood to the tissues that are further away and thus allow all to function in the best way
The rock did not become an igneous rock because igneous rock can not be formed from sedimentary rock. A metamorphic rock can be formed from a sedimentary or igneous rock but an igneous rock can not be formed from a sedimentary or metamorphic rock. Igneous rocks are formed by the cooling and hardening of molten magma only.<span />
