The endocrine system is a network of glands located throughout the head and torso. Unlike the nervous system which is directly wired throughout the body, endocrine organs are separate entities linked to each other via the cardiovascular system.
What is the cardiovascular system explained?
For the body to get oxygen, blood must be pushed from the heart through the circulatory system to the lungs. Following that, the heart pumps oxygenated blood through the arteries to the rest of the body. Veins bring blood that is oxygen-deficient back to the heart, where it is circulated again.
Why is cardiovascular important?
The cardiovascular system feeds the body's cells and organs with oxygen, nutrients, hormones, and other essential compounds. The body must be capable of meeting the demands of stress, exercise, and activity. It helps control body temperature among other things.
