QUESTION | ANSWER |
---|---|
HEART Size & Shape ? | Size of a Fist & Shaped like a Cone. |
HEART Location ? | It lies between your Lungs, just behind (posterior to) your Sternum, & the Tip (apex) of the Cone points towards the Left Nipple. Slightly to the Left Centre in your Chest. |
CARDIA ? | Relating to the HEART |
PERICARDIUM / PERICARDIAL MEMBRANES ? | There are 2 Layers to this Sac: the Fibrous Pericardium and the Serous Pericardium. The Serous Pericardium, in turn, is divided into 2 Layers; in between these 2 Layers there is a potential Space called the PERICARDIAL CAVITY. |
HEART, Inside Out (E,PC,M,E,PP) | Endocardium, Pericardial Cavity, Myocardium, Epicardium & Parietal Pericardium |
HEART, Inside Out, ENDOCARDIUM ? | This Innermost Layer of the Heart is made up of ENDOTHELIAL Tissue that Lines the Inside of the Heart. |
HEART, Inside Out, The ENDOCARDIUM is CONTINUOUS Through All Your Blood Vessels. TRUE or FALSE ? | TRUE |
HEART, Inside Out, PERICARDIAL Cavity ? | Working you way out, in this Space, you find the CORONARY VESSELS - the Blood Vessels that Supply the Tissues of the Heart with Nutrients & Oxygen |
HEART, Inside Out, MYOCARDIUM ? | This next Layer out is the Hard-Working, Contracting Muscular Layer of Your Heart |
HEART, Inside Out, EPICARDIUM ? | This Inner Layer of the Pericardium Covers the Mtocardium. |
HEART, Inside Out, EPICARDIUM Secreates ? | Secreates PERICARDIAL Fluid, which Protects the Tissues as they Rub Together when the Heart Beats. |
HEART, Inside Out, PARIETAL PERICARDIUM Location & Made of ? | Beyond the Pericardial Cavity, Working your way out to the Outside of the Heart, This Outermost Layer of the Heart is a THIN, WHITE Covering Made of Fibrous CONECTIVE Tissue. |
HEART, Inside Out, EPICARDIUM Function ? | Joins the Major Blood Vessels (such as the Aorta) to the Sternum & Diaphram. |
HEART, Inside Out, EPICARDIUM, Also Secretes ? | Like the Epicardium it Also Secretes Pericardial Fluid. |
HEART, 4 Hollow Chambers ? | Left ATRIUM, Right ATRIUM, Left VENTRICLE & Right VENTRICLE. |
HEART, Left & Right ATRIUM are Called ? | The ATRIA. |
HEART, The ATRIA are Seperated by ? | A MEMBRANE Called the INTER-ATRIAL SEPTUM. |
HEART, The VENTRICLES are Seperated by | A MEMBRANE Called the INTER-VENTRICULAR SEPTUM. |
HEART, Each Chamber of the Heart is Seperated by ? | The VALVES. |
HEART, VALVES Function ? | They Allow Measured Amount of Blood into a Chamber. |
HEART, VALVES Prevent ? | Blood Flowing Backward, Keep the Blood Flowing in the Right Direction, Which Helps Maintain the Proper Rhythm Action in the Heart. |
HEART, 2 Types of Valves ? | The ATRIO-VENTRICULAR Valves (Which are Between the Atria & the Ventricles) & SEMILUNAR Valves. |
HEART, 2 Types of ATRIOVENTRICULAR Valves ? | BICUSPID Valve has TWO Flaps & the TRICUSPID Valve Has THREE Flaps.Bi= 2 & Tri= 3 Hence the Name. |
HEART, 2 Types of SEMILUNAR Valves ? | PULMONARY Semilunar Valve & AOTRIC Semilunar Valve, both have THREE Flaps which are Shaped Like Half-Moons, Hence the name. |
HEART, Double PUMP for 2 Reasons 1st ? | the heart has TWO kinds of Chambers - Atria & Ventricles, The Atria Contract Simultaneously & then the Ventricles Contract Simultaneously. |
HEART, Double PUMP for 2 Reasons 2nd ? | The Heart Pumps Blood Through TWO Routes - the Arterial & Venous Systems. |
