The human heart is situated in a cavity slightly right to the sternum. This cavity or notch is​:

a) Pulmonary cavity

b) Cardiac notch

c) Buccal cavity

d) none

The human heart is situated in a cavity slightly right to the sternum. This cavity or notch is​ a Cardiac notch. (option b)

• "Incisura cardiaca pulmonis sinistri" or Cardiac notch is present slightly right to the sternum.
• The left lung's anterior border is slightly deflected.
• This deflection and the space generated from this deflection give the area of the cardiac notch.
• A cardiac notch gives space to the heart.
• This space is close to the surface of the mediastinum.
• Thus option b is correctly justifying the statement above.
