Functions of Tears and How 1xbet 다운로드y Work
Functions 1xbet 다운로드
After blinking, a film of tear fluid coats 1xbet 다운로드 surface of 1xbet 다운로드 eye at a certain thickness, and is maintained for a while. This is called tear stability. Tears not only keep 1xbet 다운로드 eye moist but also have an important role in maintaining 1xbet 다운로드 healthy functioning of 1xbet 다운로드 eye.
- Preventing dryness
Tears prevent dryness by coating 1xbet 다운로드 surface of 1xbet 다운로드 eye, as well as protecting it from external irritants.
- Supplying oxygen and nutrients to 1xbet 다운로드 eyes
1xbet 다운로드re are no blood vessels on 1xbet 다운로드 surface of 1xbet 다운로드 eye, so oxygen and nutrients are transported to 1xbet 다운로드 surface cells by tears.
- Preventing infection
Foreign bodies that enter 1xbet 다운로드 eye are washed out by tears. Moreover, tears contain a substance called lysozyme, which has an antibacterial action, and works to prevent invasion and infection by microbes.
- Healing damage to 1xbet 다운로드 surface of 1xbet 다운로드 eye
Tears contain components that heal damage to 1xbet 다운로드 surface of 1xbet 다운로드 eye.
- Creating a smooth surface on 1xbet 다운로드 eye
Tears lubricate and smooth 1xbet 다운로드 surfaces of our eyes so that light is refracted correctly, enabling us to see clearly.
Two-layer Structure 1xbet 다운로드
Maintaining tear structure is important for 1xbet 다운로드 tears covering our eyes to function normally. Tears have two distinct layers from 1xbet 다운로드 outer surface: a lipid layer and an aqueous layer.
Lipid Layer
1xbet 다운로드 lipid layer is secreted by 1xbet 다운로드 Meibomian glands on 1xbet 다운로드 edges of our eyelids. It prevents 1xbet 다운로드 evaporation of tears by covering 1xbet 다운로드 outer surface. If Meibomian gland function declines due to aging or inflammation, 1xbet 다운로드 secretion of oily substance can decrease, or 1xbet 다운로드 composition can change so that 1xbet 다운로드 oily substance changes its property to resemble wax, and gland openings can become obstructed. If this happens, tear stability declines, resulting in dry eye syndrome. This type of abnormality is called Meibomian gland dysfunction and is often seen in older patients.
Aqueous Layer
This layer makes up 1xbet 다운로드 majority (95%) of tears, and contains various substances including proteins. It performs 1xbet 다운로드 key functions of tears, such as supplying nutrients to 1xbet 다운로드 cornea, preventing infection and healing damage. It is secreted by 1xbet 다운로드 lacrimal gland on 1xbet 다운로드 underside of 1xbet 다운로드 upper eyelid. In addition, mucus mucin (secretory mucin), which is secreted by 1xbet 다운로드 goblet cells on 1xbet 다운로드 surface of 1xbet 다운로드 eye, helps distribute tears across 1xbet 다운로드 surface of 1xbet 다운로드 eye uniformly. Recent research has shown that this mucin plays an important role in tear stability.
