D

Explanation: 

Detailed explanation-1: -Veins have two main purposes. One purpose is to collect oxygen-poor blood throughout your body and carry it back to your heart. The other purpose is to carry oxygen-rich blood from your lungs to your heart.

Detailed explanation-2: -As blood travels through the body, oxygen is used up, and the blood becomes oxygen poor. Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.

Detailed explanation-3: -veins-they carry blood, lacking in oxygen, back towards your heart, and get bigger as they get nearer your heart.

Detailed explanation-4: -Blood flows through a network of vessels called the circulatory system. When blood returns to your heart, it flows to your lungs to receive oxygen. Then your heart pumps that blood out to the rest of your body, and the process begins again.
