	== ~~Development~~ ==		==Bulbus cordis==
			The '''bulbus cordis''' is a crucial embryological structure in the developing heart of vertebrates. It plays a significant role in the formation of the heart's outflow tracts and is essential for proper cardiovascular development.

	~~The bulbus cordis develops during the third week of~~ [[~~embryogenesis]]~~. ~~It is initially a cylindrical structure that is connected to the [[primitive ventricle]] on one end and the [[truncus arteriosus]] on the other. As the heart begins to form,~~ the bulbus cordis ~~moves and rotates, eventually forming~~ the ~~right ventricle and outflow tracts~~.		[[File:Gray460.png\|thumb\|right\|Diagram of the bulbus cordis in the developing heart.]]

	== ~~Structure~~ ==		===Development===
			The bulbus cordis arises during the early stages of heart development. It is one of the primary components of the primitive heart tube, which also includes the [[sinus venosus]], [[atrium]], [[ventricle]], and [[truncus arteriosus]]. The bulbus cordis is located between the primitive ventricle and the truncus arteriosus.

	~~The~~ bulbus cordis ~~is divided into two parts:~~ the ~~conus cordis~~ and the ~~truncus arteriosus~~. The ~~conus cordis forms the upper~~ part of the ~~right ventricle~~, ~~while~~ the ~~truncus~~ arteriosus ~~forms~~ the ~~roots and ascending portions~~ of the ~~aorta and pulmonary artery~~.		During embryogenesis, the bulbus cordis undergoes significant morphological changes. It elongates and contributes to the formation of the [[right ventricle]] and the outflow tracts of both the right and left ventricles. The distal part of the bulbus cordis, known as the conus arteriosus, becomes incorporated into the outflow tracts of the heart.

	~~== Clinical significance ==~~		[[File:Gray461.png\|thumb\|left\|Illustration showing the position of the bulbus cordis in relation to other heart structures.]]

	~~Abnormalities in the development~~ of the bulbus cordis ~~can lead~~ to ~~several [[congenital~~ heart ~~defects]], including [[tetralogy~~ of ~~Fallot]],~~ [[~~transposition of the great arteries~~]], and [[~~persistent truncus arteriosus~~]]~~. These conditions can have serious effects on the heart's ability~~ to ~~pump blood effectively, and often require surgical intervention~~.		===Function===
			The primary function of the bulbus cordis is to facilitate the proper alignment and separation of the outflow tracts. This is crucial for the correct routing of blood from the heart to the lungs and the rest of the body. The bulbus cordis helps ensure that the [[pulmonary artery]] and the [[aorta]] are properly positioned and connected to their respective ventricles.

	== ~~See also~~ ==		===Clinical Significance===
			Abnormal development of the bulbus cordis can lead to congenital heart defects. These defects may include malformations such as [[tetralogy of Fallot]], [[transposition of the great arteries]], and [[double outlet right ventricle]]. Such conditions often require surgical intervention to correct the anatomical abnormalities and restore normal cardiac function.

			[[File:Gray462.png\|thumb\|right\|Cross-section of the developing heart showing the bulbus cordis.]]

			===Evolutionary Perspective===
			The bulbus cordis is an evolutionary adaptation that allows for the efficient separation of oxygenated and deoxygenated blood in vertebrates. This separation is vital for maintaining high metabolic rates and supporting complex organ systems.

'''Bulbus cordis''' is an embryonic structure that forms part of the developing [[heart]] in a [[fetus]]. It is one of the five primitive sections of the heart that eventually develop into the mature heart structure. The bulbus cordis is responsible for the formation of the right [[ventricle]] and the outflow tracts of the heart, including the [[pulmonary artery]] and [[aorta]].

== Development ==

The bulbus cordis develops during the third week of [[embryogenesis]]. It is initially a cylindrical structure that is connected to the [[primitive ventricle]] on one end and the [[truncus arteriosus]] on the other. As the heart begins to form, the bulbus cordis moves and rotates, eventually forming the right ventricle and outflow tracts.

== Structure ==

The bulbus cordis is divided into two parts: the conus cordis and the truncus arteriosus. The conus cordis forms the upper part of the right ventricle, while the truncus arteriosus forms the roots and ascending portions of the aorta and pulmonary artery.

== Clinical significance ==

Abnormalities in the development of the bulbus cordis can lead to several [[congenital heart defects]], including [[tetralogy of Fallot]], [[transposition of the great arteries]], and [[persistent truncus arteriosus]]. These conditions can have serious effects on the heart's ability to pump blood effectively, and often require surgical intervention.
