Here are some of the “non-vital organs”.

Biblical cosmology is the biblical writers’ conception of the cosmos as an organised, structured entity, including its origin, order, meaning and destiny.

(In the graphic: Ga means “billion years ago”; Ma, “million years ago”.) Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Over time, the Earth cooled, causing the formation of a solid crust, and allowing liquid water on the surface.

• Spleen. This organ sits on the left side of the abdomen, towards the back under the ribs.
• Stomach.

It’s actually the remnant of a third eyelid. Known as the “plica semilunaris,” it’s much more prominent in birds and a few mammals, and functions like a windshield wiper to keep dust and debris out of their eyes. But in humans, it doesn’t work. It’s vestigial, meaning it no longer serves its original purpose.

The eyelid crease is formed by attachments between the skin and the muscle in the eye orbit, which keeps the upper eyelid lifted. A triple eyelid forms when the one main eyelid fold morphs into two or more folds. This can happen suddenly.

What is “cherry eye”? “Cherry eye” is a common term for prolapse of the third eyelid gland. The third eyelid also contains a special gland that produces a significant portion of the eye’s protective tear film. When this gland prolapses or “pops out”, the condition is known as “cherry eye”.

“Cherry eye,” as it is commonly referred to, is a prolapsed gland of the nictitans. It occurs after a tear gland in a dog’s third eyelid becomes inflamed. While it is usually not extremely painful, sometimes a dog will rub at it as if it were itchy.

Although it isn’t an emergency, a cherry eye can cause some severe problems for the dog. As with Lydia’s dog, most dogs that get a “cherry eye” are less than two years of age. If it prolapses once, it is likely to happen again.

In general pet owners can expect the average cost of Cherry Eye surgery to average $300 to $500 for one eye and up to $800 for both2.
