Is a Woman's Heart Under Her Breast?

Published in Human Anatomy 2 mins read

Yes, a portion of a woman's heart is located around and under the left breast. However, it's important to understand the full picture of the heart's location.

Understanding the Heart's Location

The heart is not exclusively under the left breast. It's situated in the chest cavity, specifically in the mediastinum, which is the space between the lungs. Here's a breakdown:

  • Location: The heart is centrally located in the chest, slightly offset to the left.
  • Position: It sits behind the sternum (breastbone) and between the lungs.
  • Proximity to Left Breast: A portion of the heart, particularly the left ventricle, lies behind and somewhat beneath the left breast.

Why the Confusion?

The perception that the heart is solely under the left breast likely comes from the fact that the heartbeat is often felt more strongly on the left side of the chest. This is because the left ventricle, the heart's strongest pumping chamber, is located more on the left side and its contractions are more pronounced.

Organs Near the Left Breast (Including the Heart)

As indicated in the reference material, several vital organs are located in the left side of the body near the left breast, including:

  • Heart
  • Spleen
  • Stomach
  • Pancreas
  • Large Intestine
  • Left Lung
  • Left Kidney

Therefore, while the heart is not entirely under the left breast, it's accurate to say a portion of it resides in that general area.
