HILUS Meaning and
Definition
-
Hilus is a noun that refers to a small depression, hollow, or opening located on the surface or interior of an organ or structure in the body. It can also be used to describe the concave or indented area on the surface of certain plants, particularly seeds.
In anatomy, the hilus typically refers to the rounded or slit-like region where blood vessels, nerves, and lymphatic vessels enter or exit an organ. It is commonly found in organs like the kidney, spleen, and lungs. The hilus serves as a gateway for the passage of vessels and nerves into the deeper parts of an organ, allowing for the transfer of essential substances and information to and from the organ. For example, in the kidney, the hilus provides an entry point for the renal artery and veins, as well as the ureter.
In botany, the hilus refers to the small scar or mark present on seeds where they were attached to the parent plant. It is often seen as a distinct spot or depression on the seed coat and serves as a point of attachment for nourishment during development or as a site for water absorption during germination. The hilus can vary in shape and size and is an important characteristic in seed identification.
Overall, whether referring to anatomy or botany, the term hilus denotes a specific anatomical feature on an organ or a distinct mark on a seed that plays a significant role in the functioning or development of the respective organism.
