True:
- Blood picks up carbon dioxide from the cells of the body.
- Blood flows from the heart to the lungs to pick up oxygen.
- Blood delivers sugar and nutrients to cells in the body.

False (and why):
- Blood picks up oxygen from the cells of the body — false: blood delivers oxygen to cells; it picks up oxygen in the lungs.
- Blood delivers carbon dioxide to cells in the body — false: blood carries carbon dioxide away from cells to the lungs for removal.
- Blood flows from the lungs to the heart to pick up oxygen — false: blood flows from the lungs to the heart already carrying oxygen; oxygen is picked up in the lungs, not in the heart.
