Additionally, the slow rate of respiration in plants does not require an extensive oxygen transport system like animals. Related Questions: Name the structure through which the … Read more

Explain how the respiratory and circulatory systems work together in humans.

The respiratory and circulatory systems work closely together to ensure the delivery of oxygen to tissues and removal of carbon dioxide from the body. The respiratory system brings oxygen into the lungs during inhalation and removes carbon dioxide during exhalation. Oxygen diffuses into the bloodstream, where it binds to hemoglobin in red blood cells. These … Read more
