2. CARDIO-VASCULAR SYSTEM The system which is related with the Heart & Blood COMPONENTS OF CVS:- * Heart *Blood vessel -vein -artery -microcirculation/capillary CARDIO-VASCULAR SYSTEM The system which is related with the Heart & Blood COMPONENTS OF CVS:- * Heart *Blood vessel -vein -artery -microcirculation/capillary

3. COMPONENTS OF THE HEART:- * Four chamber * Four chamber -Left atrium -Left atrium -Right atrium -Right atrium -Left ventricle -Left ventricle -Right ventricle -Right ventricle * Superior vanecava (Attach with the Right atrium) * Superior vanecava (Attach with the Right atrium) * Inferior vanecava (Attach with the Right atrium) * Inferior vanecava (Attach with the Right atrium) * Pulmonary vein (Attach with the left atrium) * Pulmonary vein (Attach with the left atrium) * Pulmonary artery (Attach with the right ventricle) * Pulmonary artery (Attach with the right ventricle) * Aorta * Aorta * SA (Syno-atrial) node * SA (Syno-atrial) node *AV (Atrioventricular) valve *AV (Atrioventricular) valve * Bi & Tri caspid valve * Bi & Tri caspid valve * Purkinjee fibre * Purkinjee fibre * Three coverings * Three coverings -Pericardium -Pericardium -Myocardium (Cardiac muscle) -Myocardium (Cardiac muscle) -Endocardium -Endocardium

4. HEART/CARDIAC RATE `Heart rate is the number of heart beat per minute’ In fetus:140-160bpm In fetus:140-160bpm In children:120-140bpm In children:120-140bpm Adult:60-100bpm Adult:60-100bpm Average:72bpm Average:72bpm#TACHYCARDIA `When the heart rate is greater then 100bpm it is called Tachycardia’ `When the heart rate is greater then 100bpm it is called Tachycardia’ Due to- Due to- -Excessive water intake -Excessive water intake -Mental hasitation -Mental hasitation -Exercise -Exercise -Disease condition (fever, rheumatic fever, arthritis) -Disease condition (fever, rheumatic fever, arthritis)

5. #BRADYCARDIA `When the heart rate is lower then 60bpm it is called Bradycardia’ Due to- Due to- -Excessive water loss -Excessive water loss -Tension -Tension -Excessive rest -Excessive rest -Disease condition (Diarrhoea, vomiting) -Disease condition (Diarrhoea, vomiting)

6. BLOOD PRESSURE `Blood pressure is the lateral pressure exerted by the blood on per unit area of the blood vessel’ BLOOD PERUNIT AREA OF BV BLOOD PERUNIT AREA OF BV BLOOD PRESSURE BLOOD PRESSURE NORMAL PRESSURE: 80-120mmHg

7. TYPES:- Mainly it has two types- Mainly it has two types- *Systolic pressure *Systolic pressure *Diastolic pressure *Diastolic pressure *SYSTOLIC PRESSURE `The pressure which is found by the ventricular systole’ `The pressure which is found by the ventricular systole’ Normal systolic pressure:120-140mmHg Normal systolic pressure:120-140mmHg

8. DIASTOLIC PRESSURE `The pressure which is found by the ventricular diastole’ Normal diastolic pressure:70-90mmHg Normal diastolic pressure:70-90mmHg

9. HEART SOUND:- The sound which is produced by the heart due to the vibration of the atrio-ventricular valve or intra cardiac blood flow’ HEART SOUND: LUB-DUB-LUB-DUB TYPES:- *First HS(S1) *First HS(S1) *Second HS(S2) *Second HS(S2) *Third HS(S3) *Third HS(S3) *Fourth HS(S4) *Fourth HS(S4)

10. * s1 due to closure of the AV valve *s2 due to closure of the semilunar valve *s3 due to first rapid filling phase *s4 is due to the second rapid filling phase
