Which of the following is NOT a function of the cardiovascular system (CVS)?

The cardiovascular system (CVS), primarily consisting of the heart, blood vessels, and blood, plays several vital roles in the body. One of its main functions is transporting oxygen from the lungs to tissues and carbon dioxide from the tissues back to the lungs. Additionally, it is responsible for transporting nutrients absorbed from the digestive tract as well as waste products to organs that will remove or process them, such as the kidneys.

Fighting infections is another significant function of the cardiovascular system, primarily through the transportation of white blood cells and antibodies that are crucial for the immune response.

However, maintaining blood glucose levels is not a direct function of the cardiovascular system. Instead, this regulation is primarily managed by the endocrine system, specifically through hormones such as insulin and glucagon produced by the pancreas. The cardiovascular system supports these processes by ensuring that hormones can be transported throughout the body in the bloodstream, but it does not directly regulate blood glucose levels itself.
