Arteries
Blood leaving heart
Veins
Blood toward heart
Diastolic
Bp between contractions
Systolic
Bp during contraction
What dues our body need grom our cardiovascular system to perta emercise
High oz delivery high resource delirry signaling
Fixed principle
Vo2=Q(CaO2-CvO2)
Cardiac output
Q
Amount of blood pumped out of the heart (4/min)
Children increase 3/4x times during exercise 20-30% changes in sv
Spontaneous rhythmicity
The hearts ability to produce electrical signal without outside influence
Stroke volume
Amount of blood pumped out per beot
Linear with bod mass
Sv= edv-esv
Increase in sv caused by rise n er, reducessystojc vascular resistance
Frank starling mechanism
Myocardial sibers stretch, contractile ability of heart increases
>stretch=> contractile
Diastolic function
Ability of the ventricle to all during diastole is determined by a gradient caused by 2 types of pressure
Upstream pressure
Pressure caused by the blood entering the ventricle and is facilitated by the pressure of the blood entering the heart, and left atrial volume and contractile force
Downstream pressure
Pressure prevents blood from entering the ventricle. Caused by the end systolic ventricular pressure and the speed of relaxation of the ventricle
Heart chamber volume
During exercise may und diastolic volume of the heart chamber itself may increase slightly
Decrease systolic volume which contributes the most to the change in total su
Systemic vascular resistance
Lowers during exercise
Caused by vasodialation of prepheral blood vessels in the working muscles
Allows blood to leave the heart
