A
to provide structural support to the body
B
to eliminate waste products like carbon dioxide from the body
C
to transport gases throughout the body
D
carries oxygen, nutrients, and hormones to cells
Explanation: 

Detailed explanation-1: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-2: -Functions of blood and circulation: Circulates OXYGEN and removes Carbon Dioxide. Provides cells with NUTRIENTS. Removes the waste products of metabolism to the excretory organs for disposal. Protects the body against disease and infection.

Detailed explanation-3: -Haemoglobin molecules inside red blood cells pick up and carry the oxygen. These oxygen-rich cells travel in the blood vessels from the lungs to the left side of the heart. The blood is then pumped around the body. Red blood cells are adapted for the transport of oxygen.

Detailed explanation-4: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.

Detailed explanation-5: -Final answer: Removal of waste products for excretion from the body is not an important function of the vertebrate circulatory system.
