CARDIO-VASCULAR SYSTEM
The system which is related with the Heart &
Blood
COMPONENTS OF CVS:-
*Heart
*Blood vessel
-vein
-artery
-microcirculation/capillary
COMPONENTS OF THE HEART:*Four chamber
-Left atrium
-Right atrium
-Left ventricle
-Right ventricle
* Superior vanecava (Attach with the Right atrium)
* Inferior vanecava (Attach with the Right atrium)
* Pulmonary vein (Attach with the left atrium)
* Pulmonary artery (Attach with the right ventricle)
* Aorta
* SA (Syno-atrial) node
*AV (Atrioventricular) valve
* Bi & Tri caspid valve
* Purkinjee fibre
* Three coverings
-Pericardium
-Myocardium (Cardiac muscle)
-Endocardium
HEART/CARDIAC RATE
`Heart rate is the number of heart beat per minute’
In fetus:140-160bpm
In children:120-140bpm
Adult:60-100bpm
Average:72bpm
#TACHYCARDIA
`When the heart rate is greater then 100bpm it is called Tachycardia’
Due to-Excessive water intake
-Mental hasitation
-Exercise
-Disease condition (fever, rheumatic fever, arthritis)
#BRADYCARDIA
`When the heart rate is lower then 60bpm it is called
Bradycardia’
Due to-Excessive water loss
-Tension
-Excessive rest
-Disease condition (Diarrhoea , vomiting)
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 PRESSURE
NORMAL PRESSURE: 80-120mmHg
TYPES:Mainly it has two types*Systolic pressure
*Diastolic pressure
*SYSTOLIC PRESSURE
`The pressure which is found by the ventricular
systole’
Normal systolic pressure:120-140mmHg
DIASTOLIC PRESSURE
`The pressure which is found by the ventricular
diastole’
Normal diastolic pressure:70-90mmHg
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)
*Second HS(S2)
*Third HS(S3)
*Fourth HS(S4)
*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
