CHAPTER 20 CARDIOVASCULAR REVIEW
|
|
|
WHAT IS THE STUDY OF THE HEART CALLED?
|
CARDIOLOGY
|
|
|
THE HEART HAS TWO PUMPS IN ONE. WHAT ARE THEY?
|
1. PULMONARY CIRCULATION
2. SYSTEMIC CIRCULATION |
|
|
HOW MUCH BLOOD DOES THE HEART PUMP:
PER DAY? PER MIN? DURING EXERCISE? |
7200L PER DAY
AT 5L PER MINUTE DURING EXERCISE INCREASES SEVERALFOLD. |
|
|
WHAT ARE THE 4 FUNCTIONS OF THE HEART?
|
1. GENERATING BLOOD PRESSURE
2. ROUTING BLOOD 3. ENSURING ONE-WAY BLOOD FLOW 4. REGULATING BLOOD SUPPLY |
|
|
WHAT ARE THE LAYERS OF THE HEART?
|
PERICARDIUM->FIBROUS
->SEROUS->PARIETAL ->VISCERAL -PERICARDIAL CAVITY |
|
|
WHAT HAPPENS WHEN THE SEROUS PERICARDIUM BECOMES INFLAMED?
|
PERICARDITIS
STAGE 1 __ SEROUS FLUID->FRICTION STATE 2 __ SEROUS FLUID->HEART COMPRESSION |
|
|
WHAT ARE THE LAYERS OF THE HEART WALL?
|
EPICARDIUM
MYOCARDIUM ENDOCARDIUM |
|
|
BE ABLE TO IDENTIFY AND DESCRIBE THE ATRIA, VENTRICLES, AND VESSELS OF THE HEART.
|
1.ATRIA-UPPER THIN WALLED;
-INTERATRIAL SEPTUM (SEPARATES LEFT & RIGHT) 2.VENTRICLES- LOWER CHAMPBERS OF THE HEART,THICK, LEFT THICKER THAN THE RIGHT,INTRAVENTRICULAR SEPTUM(SEPARATES THE LEFT FROM RIGHT) -PAPILLARY MUSCLES CAUSE VENTRICULAR CONTRACTION 3. VALVES- TRICUSPID (RIGHT AV) - BICUSPID (MITRAL LEFT AV) 4. VESSELS- -PULMONARY VEIN- CARIES BLOOD FROM LUNGS TO HEART *ONLY VEIN THAT CARRIES O2 RICH BLOOD. -PULMONARY ARTERY-HEART TO LUNGS -SUPERIOR VENA CAVA- COLLECTS IN HEAD AND NECK -INFERIOR VENA CAVA-COLLECTS BLOOD FROM LOWER REGIONS OF THE BODY. |
|
|
WHAT ARE THE LAYERS OF AN ARTERY?
|
1. TUNICA INTIMA
- INNER MOST LAYER - SIMPLE SQUAMOUS - RESTS ON BASEMENT MEMBRANE - ELASTIC PROPERTIES (LAMINA) 2. TUNICA MEDIA -MIDDLE LAYER -RESTS ON BASEMENT MEMBRANE -THICKEST -CIRCULAR SMOOTH MUSCLE & ELASTIN -VASODILATED (INCREASE BLOOD VESSEL DIAMETER) -VASOCONSTRICTION (DECREASE BLOOD VESSEL DIAMETER) 3. TUNICA ADVENTITIA- OUTER MOST; COLLAGEN |
