The choroid and auricle are similar because one collects light and the other collects sound.
false. the choroid is the opaque middle layer of the eye that contains blood vessels and provides the blood supply for the entire eye.
The cerebrospinal fluid (CSF) is produced from arterial blood by the choroid plexuses of the lateral and fourth ventricles by a combined process of diffusion, pinocytosis and active transfer. A small amount is also produced by ependymal cells. The choroid plexus consists of tufts of capillaries with thin fenestrated endothelial cells. These are covered by modified ependymal cells with bulbous microvilli.
Absorbs light, and protects your eye.

what are choroid bodies?
Choroid Plexuses
choroid is black in colour with a lot many nerve fibres to nourish the organ that is eye.

One of the two muscles that make up the front part of the choroid is the ciliary muscles. Another one that makes up the choroid is the iris.
Damage to choroid plexus would interfere with the production of CSF (cerebrospinal fluid).
Well, the theory right now is the majority of CFS is produced within the ventricles the choroid plexus produces by a combined process of diffusion, pinocytosis and active transfer of arterial blood and the rest is produced by modified ependymal cells of the choroid plexus.
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.

The choroid forms the bulk of the heavily pigmented vascular layer.

The choroid, also known as the choroidea or choroid coat, is the vascular layer of the eye, containing connective tissue, and lying between the retina and the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm.[1] The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms theuveal tract.
