<p><b>New page</b></p><div>'''Heart development''' refers to the process by which the [[heart]] forms in the embryo. This process begins shortly after conception and continues throughout pregnancy. The development of the heart is a complex process that involves a series of coordinated events, including the formation of the heart tube, looping of the heart tube, and the formation of the heart chambers and valves.<br />
<br />
== Formation of the Heart Tube ==<br />
The heart begins to form in the embryo as a simple tube, known as the heart tube. This tube is formed from a layer of cells called the [[endoderm]], which lines the inside of the early embryo. The endoderm cells begin to fold inwards and meet in the middle to form the heart tube. This process is known as [[gastrulation]].<br />
<br />
== Looping of the Heart Tube ==<br />
Once the heart tube has formed, it begins to loop. This looping process is crucial for the correct positioning of the heart chambers and valves. The heart tube first bends to the right and then to the left, forming a loop. This process is known as [[cardiac looping]].<br />
<br />
== Formation of the Heart Chambers and Valves ==<br />
The heart tube then begins to form the different chambers of the heart, including the [[atria]] and the [[ventricles]]. This process is known as [[chamber specification]]. The heart tube also forms the heart valves, which ensure that blood flows in the correct direction through the heart. This process is known as [[valve formation]].<br />
<br />
== Regulation of Heart Development ==<br />
The development of the heart is regulated by a number of different factors, including [[genes]], [[growth factors]], and [[signaling pathways]]. These factors work together to ensure that the heart develops correctly.<br />
<br />
== Abnormal Heart Development ==<br />
Abnormal heart development can lead to a number of different [[congenital heart defects]], including [[atrial septal defect]], [[ventricular septal defect]], and [[tetralogy of Fallot]]. These defects can have serious consequences for the health of the individual and may require surgical intervention.<br />
