Question

place the following vessels in order starting at the top with those that have the highest blood pressure to those that have the lowest blood pressure at the bottom.
instructions
venule
systemic artery
aorta
capillary
systemic vein

Explanation:

To determine the order of blood vessels by blood pressure, we use knowledge of the circulatory system:

1. The Aorta is the main artery carrying blood from the heart, with the highest pressure.
2. Systemic arteries branch from the aorta and still carry high - pressure blood (though slightly less than the aorta).
3. Capillaries are where gas and nutrient exchange occurs; pressure drops here as blood moves through the narrow capillaries.
4. Venules are small veins that collect blood from capillaries; pressure is lower than in capillaries.
5. Systemic veins carry blood back to the heart and have the lowest pressure among these vessels.

So the order from highest to lowest blood pressure is Aorta, Systemic artery, Capillary, Venule, Systemic vein.

Answer:

1. Aorta
2. Systemic artery
3. Capillary
4. Venule
5. Systemic vein
