Pericardium
Superficial covering of the heart, fibrous
2 serous layers of the pericardium
—> parietal layer of serous pericardium
—> visceral layer of serous pericardium
3 layers of the heart wall
- Epicardium
- Myocardium
- Endocardium
Epicardium
Visceral layer of the serous pericardium
- has fat
Myocardium
Muscle
Fibrous skeleton of the heart
—> limits spread of AP to specific paths
—> anchors cardiac muscle fibers
—> supports vessels + valves
Endocardium
Inside layer of the heart
-continuous with endothelium
Base
-towards the back
-directed to the right shoulder
Apex of the heart
Points towards left hip
Coronary sulcus
Separates atria and ventricles
Auricle of the atria
Ears of the atria
Increase volume of the atria
Like the walk in closets of the heart
Inter-atrial septum
Separates right and left atria
3 vessels that enter right atrium
- Superior vena cava
- Inferior vena cava
- Coronary sinus: brings the deoxygenated blood that fed the heart
4 vessels that enter the left atrium
Left superior + inferior pulmonary veins
Right superior + inferior pulmonary veins
_____ lines the wall of the ventricles
Trabeculae carneae
Vessel leaving the right ventricle
Pulmonary trunk
-splits into right + left pulmonary artery
Vessel leaving the left ventricle
Aorta
Av valves
Between atria and ventricles
—> tricuspid valve: between right atria + ventricle
—> mitral/bicuspid valve: between left atria + ventral
Semi-lunar valves
Between ventricles + vessels
—> aortic semi-lunar valve
—> pulmonary semi-lunar valve
Compliance
How much your lung can stretch / the volume
Pathway of blood throughout the heart
- Superior vena cava, inferior vena cava, coronary sinus
- Right atrium
- Tricuspid valve
- Right ventricle
- Pulmonary semi-lunar valve
- Pulmonary trunk
- Lungs
- Pulmonary veins
- Left atrium
- Mitral/bicuspid valve
- Left ventricle
- Aortic semi-lunar valve
- Aorta
Pulmonary circuit
Low pressure, short
Systemic
High pressure, left ventricle muscle is super thicc and built vs . Right ventricle
7 coronary arteries
Supply the heart with blood
1/2. Right/left coronary artery
3/4. Right/left marginal artery
5/6. Anterior/posterior interventricular artery
7. Circumflex artery
Right coronary artery supplies
Right atria + right ventricle
Left coronary artery supplies
Left ventricle + atria
