statement is true about venules?
eukocytes can transmigrate through venules and enter the interstitial space.
eins drain blood into them in systemic circulation.
they carry mostly oxygenated blood.
they are directly connected to arteries.

Explanation:

To determine the true statement about venules, we analyze each option:

1. Leukocytes (white blood cells) can transmigrate (exit the bloodstream) through venular walls into the interstitial space during immune responses or inflammation. This is a known physiological process.
2. In systemic circulation, venules drain into veins (not the other way around), so the second option is incorrect.
3. Venules carry deoxygenated blood (as they are part of the venous return system), so the third option is incorrect.
4. Venules are connected to capillaries (not directly to arteries), so the fourth option is incorrect.

Answer:

Leukocytes can transmigrate through venules and enter the interstitial space.
