Yes, an opening in a wall that allows rainwater to drain into the downspout and stormwater drainage system is typically referred to as a weep hole. These openings are designed to prevent water buildup and reduce pressure on the wall, helping to direct excess rainwater away from the structure. Properly placed weep holes enhance drainage efficiency and protect the integrity of the building.
Vent
The area underground that rainwater passes through is called the "unsaturated zone" or "vadose zone." This zone lies between the ground surface and the water table, and it allows rainwater to percolate through soil and rock.
Yes, a kitchen sink does require a vent for proper drainage and ventilation. The vent allows air to enter the plumbing system, preventing airlock and ensuring smooth drainage.
A volcano or volcanic vent is an opening in the earth's surface that allows melted rock (lava) to flow out.

Pupil.
That's called a vent.
Sandy soils with a loose texture allow for the most rainwater infiltration due to their high permeability, which allows water to pass through easily. Well-structured soils with plenty of organic matter also facilitate rainwater infiltration by improving soil porosity and reducing surface runoff. Compacted or clayey soils that are prone to waterlogging restrict rainwater infiltration.
Yes, a surgical incision of the eardrum to create an opening for the placement of ear tubes is known as a myringotomy. This procedure allows for the drainage of fluid from the middle ear and helps prevent future infections by facilitating air flow. Ear tubes are then inserted through the incision to maintain the opening and promote ventilation. Myringotomy is commonly performed in children with recurrent ear infections or chronic otitis media.
The stoma (stomata)
The opening hole of the eye is called the pupil. It is the black circular opening located in the center of the iris that allows light to enter the eye. The size of the pupil can change in response to different lighting conditions and emotions.
A funnel is a tool that allows liquid to flow away by guiding it into a narrow opening.
