Is it true or false the transverse sinuses receive most of the blood leaving the heart?

False. The transverse sinuses are not responsible for receiving blood leaving the heart; rather, they are part of the venous drainage system of the brain, receiving blood from the superior sagittal sinus and other tributaries. Most blood leaving the heart is carried away by the arteries, primarily the aorta, which distributes oxygenated blood to the body. The transverse sinuses primarily deal with venous blood returning from the brain back to the heart.
