Final answer:
The statement is false; the circulatory and cardiovascular systems refer to the same network that includes both the systemic and pulmonary circuits. Blood is oxygenated in the pulmonary veins and deoxygenated in the pulmonary artery.
Step-by-step explanation:
The statement that the circulatory system brings blood to and from the body, while the cardiovascular system brings blood to and from the lungs only, is false. The terms circulatory system and cardiovascular system are often used interchangeably; they refer to the network that transports blood throughout the body, which includes bringing oxygenated blood to the tissues and returning deoxygenated blood to the lungs. The system is divided into the systemic circuit, which transports blood throughout the body, and the pulmonary circuit, which transports blood to and from the lungs.
A closed circulatory system is one where the blood is contained within blood vessels and is separated from the bodily interstitial fluid. The blood circulates unidirectionally from the heart around the systemic circulatory route and then returns to the heart. This is seen as a more efficient method for transporting gases, nutrients, and waste around the body, as compared to an open circulatory system where blood mixes with interstitial fluid and is not always contained within vessels.
In regards to the false statements about the circulatory system, blood in the pulmonary veins is oxygenated (not deoxygenated), and blood in the pulmonary artery is deoxygenated (not oxygenated). Therefore, the correct answer for the question which of the following statements about the circulatory system is false would be: Blood in the pulmonary veins is deoxygenated.
