During exchange at the capillaries,what can cross the endothelial cells,diffusing through the plasma membranes?

Question

Quizplus · Accepted Answer

Lipid-soluble substances, such as oxygen and carbon dioxide, can diffuse through the plasma membranes of endothelial cells during exchange at the capillaries. Proteins and large water-soluble substances cannot pass through the membrane, and red blood cells are too large to pass through the narrow capillary openings. Hormones may be able to cross, but it depends on their specific properties.
