- 13. The deoxygenated blood enters in from the bottom of the heart from the body
- 14. Which blood vessel has the largest lumen?
Down
- 1. Deoxygenated blood enters from the right ventricle to here and this sends blood to the lungs
- 2. regulate gas exchange between the plant and environment and control of water loss
- 3. which blood vessel carries blood away from the heart?
- 5. is the net transfer of particles across a concentration gradient from an area of high concentration to low
