Question

Which statement about the capillaries is FALSE?

1) Carbon dioxide is generally traveling from the tissues toward the capillaries
2) Total cross-sectional area in the capillaries is higher than in the veins
3) None of these
4) Compared to veins and arteries, velocity of flow is lowest in the capillaries
5) Oxygen is generally traveling from the capillaries toward the tissues

Answer 1

The FALSE statement about capillaries is that carbon dioxide is generally traveling from the tissues toward the capillaries.

Step-by-step explanation:

The statement that is FALSE about capillaries is:
1) Carbon dioxide is generally traveling from the tissues toward the capillaries.

Carbon dioxide is produced in the cells as a waste product and is carried away from the tissues to the lungs through the capillaries, where it is then released during exhalation. Oxygen, on the other hand, is generally traveling from the capillaries toward the tissues, providing oxygen to the cells for cellular respiration.

Therefore, option 1 is the incorrect statement among the given options.
