What organ system supplies the body with oxygen and removes carbon dioxide?

The correct answer is the respiratory system, which plays a crucial role in gas exchange in the body. This system consists of organs such as the lungs, trachea, and bronchi that are specifically designed to facilitate the intake of oxygen and the expulsion of carbon dioxide. During the process of respiration, oxygen from the air is delivered to the bloodstream in the alveoli, the tiny air sacs in the lungs, while carbon dioxide, a waste product from cellular metabolism, is transported back to the lungs to be exhaled.

The respiratory system ensures that oxygen is supplied to the cells for energy production while concurrently removing carbon dioxide, which can be toxic at high levels. This balance is vital for maintaining homeostasis and the overall health of the organism.

In contrast, the integumentary system, which includes the skin, hair, and nails, primarily serves protective functions and does not play a direct role in gas exchange. The endocrine system regulates bodily functions through hormones but is not involved in respiratory processes. The renal system, which involves the kidneys and urinary tract, is responsible for waste removal from the body, particularly in the form of urine, but also does not handle gaseous exchange. Each of these other systems has its essential functions, yet none
