oklúzia

Okklúzia is a term used in various fields, most notably in medicine and astronomy, to describe the act or state of being closed or obstructed. In medicine, it refers to the blockage of a blood vessel, a duct, or an opening in the body. For example, an arterial occlusion is a blockage of an artery, which can lead to a stroke or heart attack. Similarly, a bowel obstruction is a blockage in the intestines. The term can also describe the closure of a joint, such as in the jaw, where teeth from the upper and lower jaws meet. This dental occlusion is a crucial aspect of proper chewing and speech.

In astronomy, okklúzia, or occlusion, describes the event where one celestial body passes in front of another, obscuring it from view. A common example is a solar eclipse, where the Moon passes between the Sun and Earth, blocking the Sun's light. Planetary occultations occur when a closer celestial body, like an asteroid or moon, passes in front of a more distant one, such as a star. These astronomical events are important for studying the properties of the objects involved, such as their size, shape, and atmosphere. The specific context will determine the precise meaning and implications of the term okklúzia.
