What is transported by the circulatory system?

The circulatory system plays a vital role in transporting various essential substances throughout the body. The correct answer highlights that oxygen, water, and both micro and macro nutrients are all crucial components transported by the circulatory system.

Oxygen is absorbed into the bloodstream in the lungs and delivered to tissues where it's utilized for cellular respiration, providing energy to cells. Water is also transported in the plasma and is essential for maintaining the body’s hydration and cellular functions. Micro and macro nutrients, such as vitamins, minerals, carbohydrates, proteins, and fats, are carried from the digestive tract to tissues, where they are used to support numerous bodily functions.

Together, these components are essential for maintaining homeostasis, supporting metabolic processes, and ensuring the overall health and functionality of the body. The circulatory system efficiently manages the distribution of these elements, making it indispensable for life.
