Cardiac notch
Cardiac Notch
The Cardiac Notch (pronounced: /ˈkɑːrdiæk nɒtʃ/) is a distinct indentation in the left lung that allows space for the heart. It is also known as the Cardiac Impression.
Etymology
The term "Cardiac Notch" is derived from the Latin words 'cardia' meaning heart and 'notch' meaning an indentation or cut.
Anatomy
The Cardiac Notch is located on the medial surface of the left lung, and it is where the heart makes an impression. This notch allows the heart to fit snugly against the lung without causing any damage or pressure. The Cardiac Notch is an important anatomical feature as it allows for the close proximity of the heart and lungs, facilitating efficient oxygen transport and circulation.
