The circulatory system, which comprises the heart, blood vessels, and blood, functions collaboratively to transport oxygen, nutrients, hormones, and waste products throughout the body. The heart pumps oxygen-rich blood from the lungs to various tissues and organs, while it returns oxygen-depleted blood back to the lungs for reoxygenation. Simultaneously, the respiratory system—consisting of the lungs, trachea, and diaphragm—facilitates gas exchange by drawing in oxygen and expelling carbon dioxide. Together, these systems ensure that cells receive the necessary oxygen for metabolic processes and eliminate carbon dioxide, thereby maintaining homeostasis and overall well-being.
