Cardiovascular

The individual serial slices have also been incorporated into a 3D model of this embryo.

The cardiovascular system extends throughout the entire embryo.

Stage 22 Embryo - Cardiovascular
Section Name Description
Stage 22 image 069.jpg C6L L and R common carotid arteries. L and R internal jugular veins.
Stage 22 image 070.jpg C7L L brachiocephalic vein (transverse anastomosis of L, R jugular veins). L common carotid artery. Brachiocephalic trunk.
Stage 22 image 071.jpg D1L Aortic arch. Thymus (retrosternal). Trachea. Oesophagus. Large L and R jugular veins.
Stage 22 image 072.jpg D2L Aortic arch. L jugular lymph sac lying laterally with hemiazygos joining it. Trachea. Oesophagus. Draining of azygos vein into R jugular vein.
Stage 22 image 073.jpg D3L Ascending aorta attached cranial to transverse pericardial sinus. Superior vena cava expanding into R jugular vein. Trachea (bifurcation). Oesophagus. Azygos (R) and hemiazygos (L) veins.
Stage 22 image 074.jpg D4L Ascending aorta. Pulmonary trunk and arteries. Thoracic aorta. Oesophagus. Bronchi. Note azygos vein on right, and precursor of hemiazygos vein on left side.

(Image excerpt different scale from previous images)

Stage 22 image 075.jpg D5L Superior vena cava. Ascending arch of aorta. Pulmonary trunk with the other two semilunar valves.

Sinus above one valve and branching of pulmonary trunk into L and R pulmonary arteries.

Stage 22 image 076.jpg D6L Superior vena cava. Ascending aorta with transverse pericardial sinus behind. Semilunar valve at origin of pulmonary trunk. L. atrium and auricle. Thoracic aorta.
Stage 22 image 077.jpg D7L R atrium with R venous valve. R ventricle close to origin of pulmonary trunk. L.ventricular wall and three semilunar valves of aortic ostium.
Stage 22 image 078.jpg E1L Section through all four chambers of heart.

left ventricle- outflow tract close to origin of ascending aorta. Deep coronary sulcus and transverse pericardial sinus.

right atrium- R venous valve of the inferior vena cava, the small septum secundum, the aperture in the dorsal part of septum primum (ostium secundum). (The foramen ovale arises later with the elongation of the septum secundum).

left atrium- entrance of the L and R pulmonary veins and the auricle.

Stage 22 image 079.jpg E2L Section through all four chambers of heart.

Ventricles. Right venous valve. Between the tiny ridge of the septum secundum of the R atrium and the R venous valve.

right atrium- drainage of the inferior vena cava (cf. E3). R atrioventricular canal. Septum primum.

left atrium- drainage sites of R and L pulmonary veins.

Stage 22 image 080.jpg E3L Section through all four chambers of heart.

Ventricles. Diaphragm and liver. Pericardium and cavity. R atrium and two cusps of the atrioventricular valve. L atrium and its auricle. Thoracic aorta. Inferior vena cava. Coronary sinus.
