MindMap Gallery Medicine - Vascular System Overview and Heart
Pictured and highlighted, the vasculature plays an important role in the human body, responsible for transporting oxygen and nutrients, while also helping to remove waste and carbon dioxide from the body.

Vascular system overview and heart
Composition of the vasculature
Cardiovascular System
composition
heart
Location
Located in the middle mediastinum of the chest, about 2/3 is on the left side of the midline, and 1/3 is on the right side of the midline. It is aligned with the body of the sternum in front, the costal cartilage of the 2nd to 6th ribs is opposite, and the costal cartilage of the 2nd to 6th ribs is opposite to the 5th to 8th ribs in the back. Thoracic vertebrae, adjacent to the esophagus and thoracic aorta, connected to the great blood vessels above, separated below, and adjacent to the lungs on both sides through the mediastinum
shape
apex - apex of heart
Toward left front and lower
Made up of right ventricle
body surface projection
Flat to the 5th intercostal space on the left side, 1 to 2 cm medial to the midclavicular line
bottom - bottom of heart
Towards the lower right rear
Left and right atrium composition
Two sides—sternocostal side, septal side
ribs
forward and upward
next door
towards back and down
Three edges - lower edge, right edge, left edge
lower edge
Horizontal, consisting of the right ventricle and apex
left edge
Oblique, formed by the left ventricle
right edge
Vertical, formed by the right atrium
The four grooves—coronary sulcus, anterior interventricular sulcus, posterior interventricular sulcus, and interatrial sulcus mean: the boundary between the left and right ventricles on the heart surface, and the course of blood vessels
heart chamber
right atrium
Special structure—fossa ovale (oval-shaped shallow depression located in the lower part of the atrial septum, only the right atrium is visible, a relic of the foramen ovale atresia during fetal life, and a common site for congenital atrial septal defects.
Entrance
Superior vena cava orifice
inferior vena cava orifice
Coronary sinus ostium
exit
Right atrioventricular orifice
right ventricle
Entrance
Right atrioventricular orifice
exit
pulmonary artery orifice
tricuspid valve complex
composition
Annulus fibrosus, tricuspid valve, chordae tendineae, papillary muscles
effect
Prevent blood from flowing backward into the right atrium
pulmonary valve
Prevents blood from flowing backward into the right ventricle (pouching)
Left atrium
Entrance
Left superior pulmonary vein orifice
Left inferior pulmonary vein orifice
Right superior pulmonary vein orifice
Right inferior pulmonary vein orifice
exit
left atrioventricular orifice
left ventricle
Entrance
left atrioventricular orifice
exit
aortic orifice
mitral valve complex
composition
annulus fibrosus, mitral valve, chordae tendineae, papillary muscles
effect
Prevent blood from flowing backward into the left atrium
aortic valve
Prevents blood from flowing backward into the left ventricle (pouching)
Three aortic sinuses, the left sinus and the right sinus have the openings of the left and right coronary arteries respectively
heart conduction system
composition
sinoatrial node
Function
The normal pacemaker of the heart (sinus rhythm)
atrioventricular node
atrioventricular bundle
left and right bundle branches
Purkinje fiber
heart blood vessels
arteries of heart
left coronary artery
branch
Anterior interventricular branch: descends in the anterior interventricular groove
Circumflex branch: follows the coronal sulcus to the diaphragm surface
Nutritional scope: left half of the heart, 2/3 of the interventricular septum and a small part of the anterior wall of the right ventricle
right coronary artery
branch
posterior interventricular branch
left ventricular posterior branch
Nutritional scope: posterior 1/3 of the right ventricular septum, small part of the posterior wall of the left ventricle, sinoatrial node and atrioventricular node
heart veins

composition
Outer layer
fibrous pericardium
inner layer
Serosal pericardium
pericardial cavity
dirty layer
wall layer
Blood vessel
artery
vein
capillaries
blood circulation path
concept
Blood is ejected from the heart - through arteries (A) - capillaries (Cap) - veins (V) - heart, over and over again, called blood circulation.
branch
