Answer
The retinal pigment epithelium (RPE) is crucial for maintaining the health and function of the retina.
Solution
a
Protection: The RPE forms a barrier that protects the retina from excess light and oxidative stress
b
Nutrient Transport: It facilitates the transport of nutrients from the choroid to the photoreceptors
c
Phagocytosis: The RPE cells phagocytize shed photoreceptor outer segments, which is essential for photoreceptor renewal
Key Concept
Retinal Pigment Epithelium (RPE)
Explanation
The RPE is a layer of cells that plays a vital role in supporting the photoreceptors in the retina by providing nutrients, removing waste, and protecting against light damage.
