Submit Request Answer

The answer is the third one: Lymph is excess tissue fluid formed from plasma that has leaked from capillaries.

Explanation for each option:

1. Lymph is secreted into the lymph vessels.

   • Incorrect. Lymph is not secreted; it is collected from interstitial fluid.

2. Lymph is fluid collected from arteriovenous anastomoses.

   • Incorrect. Arteriovenous anastomoses are connections between arteries and veins, not a source of lymph fluid.

3. Lymph is excess tissue fluid formed from plasma that has leaked from capillaries.

   • Correct. Lymph originates from interstitial fluid, which is plasma that has leaked out of capillaries into surrounding tissues.

4. Lymph is collected from fluid that accumulates in veins as blood slowly circulates back toward the heart.

   • Incorrect. Lymph is not collected from veins; it is collected from interstitial spaces.

In summary, lymph fluid is formed from excess tissue fluid that originates from plasma leaking out of capillaries.
