|
| 45. | The newly oxygenated blood drains from the gill capillaries into the systemic heart where it is then pumped back throughout the body.
|

|

|
| 49. | The carotid arteries, one on each side of the neck, are the vessels through which the heart supplies oxygenated blood to the brain.
|
| 50. | The vein carries oxygenated blood from the placenta to the baby and the arteries carry deoxygenated blood from the baby to the placenta.
