The eye contains aqueous humor between the iris and the cornea. It is always being produced and nourishes the iris and cornea and gives shape to the eye.
No, coelomates do not have a body cavity. Coelomates have a fluid-filled cavity called a coelom that is lined with mesoderm. This cavity allows for the internal organs to be suspended and protected within the body.
A tendon sheath is a fluid-filled cavity that surrounds a tendon to reduce friction and allow smooth movement. It is lined with synovial cells that secrete a lubricating fluid called synovial fluid.
The abdominal cavity contains major body organs such as the stomach, liver, intestines, and kidneys. This cavity is lined with a membrane called the peritoneum and is filled with a fluid called peritoneal fluid to help protect and cushion the organs.
Serous cavities are spaces within the body lined with a serous membrane. These cavities are filled with serous fluid that helps reduce friction between organs, allowing them to move smoothly against each other. Examples of serous cavities include the pleural, pericardial, and peritoneal cavities.
Yes, leeches are coelomate organisms. They possess a true coelom, which is a fluid-filled body cavity completely lined by mesoderm. This coelomic cavity houses the internal organs of the leech.
A sinus is an air-filled cavity within a bone that is lined with mucous membrane. Sinuses help to humidify and filter air as it passes through the nasal cavity.
The cochlea is the structure of the human ear that is filled with fluid and lined with tiny hair cells. These hair cells are responsible for converting sound vibrations into electrical signals that are then sent to the brain for processing.

Yes, sinuses are air-filled cavities located within the bones of the skull. They are lined with mucous membranes and help to humidify and filter the air we breathe in.
A paraovarian cyst is a epithelium-lined fluid-filled cysts. This type of cyst is located adjacent to the fallopian tube and ovary.
A tendon sheath is a fluid-filled cavity that surrounds a tendon to reduce friction and allow smooth movement. It is lined with synovial cells that secrete a lubricating fluid called synovial fluid.
Her funeral was held at Netaji Stadium in Calcutta, India, and it was filled to capacity. Thousands more lined the procession route from the stadium to the Mother House where she was buried.

This answer is not easy but if you really want to get into it... the eye is an organ which reacts to light for several purposes... Light comes in through the cornea, a clear tissue that covers the front of your eye. The pupil is the dark spot in the middle of your eye. It works like a camera shutter, controlling the amount of light that enters our eyes. When it's dark, the pupil dilates, or widens. When it's bright, the pupil gets smaller. Surrounding the pupil is the iris. This is the colored ring of muscle fibers that help the pupil change size. When you look at an object, light rays enter your eyes. These light rays are bent and focused by the cornea, lens, and vitreous. The vitreous is a clear jelly-like fluid that fills the inside of your eye. The lens' job is to make sure the rays come to a sharp focus on the retina at the back of the eye. Think of the retina as the film in the camera. It's lined with light-sensitive cells, called photoreceptors, that capture, upside-down, the images in our visual field. The sensitive macula, critical for sharp focus, is the most active part of the retina. A healthy macula helps us read small print and see the images in our direct line of vision. When light rays reach the retina, they're converted into electrical pulses that travel through the optic nerve to your brain. It is there that the image gets flipped right-side up. lol if that's not enough then read a book!

Echinoderms also have a spacious coelom (an open, fluid-filled body cavity lined with tissue), large gonads, and (usually) a complete gut.
