Question

Lymph flows:

a. Away from the heart only.

b. In a circular pattern within the tissues.

c. Into the capillaries.

d. Toward the heart only.

Note: I don't think its d. Toward heart only.

Answer 1

Option 'd' (Toward the heart only) is correct

Justification: Lymph flows in an open circuit from the tissues into the lymph vessels and it flows only in one direction that is towards the heart unlike the blood (which flows towards and away from the heart).

Justification for incorrect options:

• Option 'a' is incorrect because lymph flows only in one direction that is towards the heart but it will not flow away from the heart like the blood.
• Option 'b' is incorrect because unlike blood which flows in a circular pattern, lymph flows only in one direction but it will not flow in a circular pattern.
• Option 'c' is incorrect because lymph does not flow into the lymphatic capillaries.

Thank you!
