Final answer:
The order of blood circulation starts with carbon dioxide-rich blood returning to the heart, then the heart pumps the blood to the lungs to pick up oxygen. The oxygenated blood returns to the heart and is distributed throughout the body via arteries. After delivering oxygen, blood renews the cycle by picking up carbon dioxide.
Step-by-step explanation:
Blood Circulation Order
The order of blood circulation is a vital concept in understanding how blood travels through the human body, specifically between the heart, lungs, and tissues. Here is the sequence that describes the circulation order:
- Veins carry carbon dioxide-rich blood back to the heart.
- From here, the heart pumps blood to the lungs to pick up oxygen, performing gas exchange.
- Lungs bring in oxygen when you breathe, and blood drops off carbon dioxide and picks up oxygen.
- Oxygenated blood circulates back into the heart through pulmonary veins.
- The heart then pumps this oxygen-rich blood to all parts of the body through arteries.
- After arteries have delivered all of the oxygen, the blood picks up carbon dioxide from the body tissues.
This circulatory pattern maintains the consistent delivery of oxygen and removal of carbon dioxide, which is vital for the sustenance of body tissues and cellular respiration.
