Summary Introduction
To explain:
The function of sympathetic division that cause vasoconstriction in most blood vessels, but vasodilation in coronary and skeletal muscle blood vessels.
Concept introduction:
The cardiovascular system which is also known as circulatory system is a system which allows blood to flow throughout the body and transports nutrients, gases and other important enzymes in and out of the cells. The cardiovascular system is composed of two components: heart and the blood vessels. The three types of the blood vessels are: arteries, veins and capillaries.

Following a large increase in sympathetic output from the vasomotor center, what tissues will get less blood (increased resistance, reduced flow), and which ones will continue to get plenty of flow? How is sympathetic control of skeletal muscle arterioles different from other vascular beds?
what drives the enhanced sympathetic outflow to most other arterioles, the heart, and the veins and the decreased parasympathetic outflow to the heart?
What physiological factors influence cerebral blood flow? How can this be changed during stress conditions? What are the major compensatory responses to acute blood loss? List the most important hormones involved. What is a major difference between chronic and acute blood loss? Give some examples.
