| Middle mediastinum, Apex is pointing to the left inferiorly. The base of the heart is superior and broad and comes in contact with the major blood vessels in the body. |

|
Definition
| external marker for the division of the two ventricles. |

Term
|
Definition
| Blood from right side goes to lungs via pulmonary trunk, that divides into right and left pulm. arts. Carry CO2 rich blood to lungs. From lungs travels through right and left pulmonary veins to the left atrium (O2 rich). Heart lungs heart |

Term
|
Definition
| From the left ventricle the blood is pumped to the rest of the body. Then returns through Inferior and Superior Vena Cava |

Term
|
Definition
| Protective connective tissue surrounds the heart. Serous membrane, inner layer visceral pericardium. Myocardium is the muscle underneith. then come the parietal pericardium. fibrous pericardium is the dense fibrous connective tissue covering. Between visceral and parietal peric. is the pericardial cavity in which is lined with pericardial fluid. |

| Epicardium outer layer. Myocardium Thick muscular middle layer. Endocardium is the innermost endothelial layer. |

|
Definition
| Two superior chambers. Seperated by the interatrial septum. Right is entered by superior inferior vena cava and the coronary sinus. Four pulmonary veins (two right and two left enter the left atrium.) |
|
|
Term
|
Definition
| Inferior cavities in the heart. right and left are seperated by the interventricular septum. Left ventricle is 4x thicker because it has to pump through the entire body. Inner surface of the ventricle is covered with trabeculae carnae (irregular folds). |

Definition
| Right AV is tricuspid valve. Left AV is called the bicuspid or mitral valve. |

|
Definition
| Fibrous chordae tendinae attach to the cusps. These tendinae are attached to the papillary muscles. |

Term
|
Definition
| Left side semilunar valve at base of aorta. |
|
|
Term
| right and left coronary arteries |
|
Definition
| originate from asceding aorta. right travels to posterior heart and become the posterior interventricular artery. left divides into the anterior interventricular artery and circumflex artery |
|
|
Term
|
Definition
| great cardiac vein drians the anterior surface of the heart. terminates by entering the coronary sinus. middle drians the posterior surface of the heart. small cardiac vein drains the right surface of the heart. |

|
Definition
| First: brachiocephalic artery which then branches into the right subclavian artery and the right common carotid artery. Next branch is the left common carotid artery. The third branch is the left subclavian. |

Definition
| right ventricle --> pulmonary trunk --> left and right pulmonary arteries --> pulmonary arterioles -->pulmonary capillaries (surround alveoli) --> pulmonary venules --> pulmonary veins --> left atrium |
|
|
Term
| Blood supply to the head and neck |
|
Definition
| left and right common carotid arteries --> left and right external carotid arteries (supply blood to jaws, face and scalp) left and right internal carotid arteries supply blood to the brain. |
