Question
What is the main function of the neonatal circulatory system?
Answer
The primary function of the circulatory system is to transport nutrients to all parts of the body and collect waste to be excreted from the body. As blood leaves the heart, it carries nutrients and oxygen throughout the body; when it returns to the heart, it delivers carbon dioxide and other waste products to excretory organs, which then expel them. In adults, the total blood volume is approximately 8% of their body weight, and blood is responsible for delivering oxygen, food, nutrients, and hormones to all parts of the body, as well as transporting metabolic waste to excretory organs.
