Cœur

Cœur (French for "heart") is a term often used in medicine to refer to the human heart, one of the most vital organs in the human body. The heart is responsible for pumping blood throughout the body, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.

Anatomy[edit | edit source]

The human heart is located in the middle of the thorax, with its apex pointed to the left. It is divided into four chambers: the two upper chambers are called the atria, and the two lower chambers are the ventricles. The heart is surrounded by a fluid-filled sac called the pericardium, which provides protection and reduces friction as the heart beats.

Function[edit | edit source]

The primary function of the heart is to pump blood throughout the body. It does this through a sequence of events called the cardiac cycle. The cycle begins with the relaxation of the heart, followed by the contraction of the atria and then the ventricles. This cycle repeats approximately 60 to 100 times per minute, depending on the individual's age, fitness level, and other factors.

Diseases and Conditions[edit | edit source]

There are many diseases and conditions that can affect the heart, including coronary artery disease, heart failure, arrhythmias, and congenital heart defects. These conditions can lead to a variety of symptoms, such as chest pain, shortness of breath, fatigue, and irregular heartbeats. Treatment options vary depending on the specific condition and may include medication, lifestyle changes, or surgery.
