Why does blood move slower in the capillaries compared to the arterioles?Multiple ChoiceCapillaries are much wider than arterioles.Blood pressure is much higher in capillaries than in arterioles.There are many more capillaries than arterioles.Precapillary sphincters close shunting blood into capillaries.
Solution
The reason why blood moves slower in the capillaries compared to the arterioles is because there are many more capillaries than arterioles. This increased number of vessels creates a larger total cross-sectional area in the capillaries, which slows down the flow of blood. This slower flow rate allows for the necessary time for exchange of gases, nutrients, and waste materials between the blood and the body's tissues.
