Final answer:
Nutrients and oxygen are indeed distributed throughout the body's cells by the circulatory system, with the blood carrying these essential substances and removing wastes like carbon dioxide.
Step-by-step explanation:
Yes, nutrients and oxygen are distributed throughout the cells of the body via the circulatory system. The blood acts as a carrier, transporting these vital substances to cells and tissues while also ferrying away waste products like carbon dioxide.
The heart pumps oxygenated blood through the arteries, delivering oxygen and nutrients to the body's cells. Once the cells have used these substances, the deoxygenated blood carrying carbon dioxide and other wastes returns to the heart through veins and is then sent to the lungs and kidneys for the removal of wastes.
Furthermore, the cardiovascular system is not only responsible for the delivery of oxygen and nutrients, but it also plays a vital role in transporting hormones, regulating the body's pH, defending against infection, and repairing tissues.
This intricate system ensures that every cell receives the necessary components to function and survive.
