Vasodilation
when the blood vessels widen in an attempt to increase blood flow.
during exercise the vascular portion of active muscles increases through the dilation of arterioles, involving an increase in the diameter of the blood vessels and resulting in an increased blood flow to the muscles.

# data[].attributes.body
there are two types of blood pressure, systolic and diastolic and during exercise they increase, they increase due to the increased heart rate

# data[].attributes.body
The anticipatory rise is an increase in heart rate that typically occurs before an activity is going to happen. It results from an increase in activity of the sympathetic nervous system causing the adrenal glands to release adrenaline and nor-adrenaline into the blood stream.

# data[].attributes.body
Anticipatory rise is when your body begins to anticipate the exercise and your heart rate will likely increase. I

# data[].attributes.body
This occurs prior to exercise which results in stimulation from the sympathetic nervous system in order to increase heart rate before exercise is started. This mean that there is less of an oxygen debt before the exercise is started and the muscles that are going to be working have a good blood supply and supply of o2 ready for when they really need it

vasodilation
this is where the blood vessels expands, they do this so that the blood is closer to the surface of the skin so that the blood cools down. this decreases blood pressure. this happens when there is a limited amount of oxygen and a rise of lasctic acid or co2 in the blood stream, the blood vessels near to the muscles dilate so that it is in easier access to the oxygen. parasympathetic causes this

increased blood pressure
during aerobic exercise , oxygen consumption and heart rate increase in relation to the intensity of the activity. systolic blood pressure rises progressively whilst the diastolic blood pressure stays the same or decreases slightly. pulse rates rises and blood flow to your muscles increases.
systolic blood pressure- the highest pressure within the blood stream which occurs during each beat when the heart rate is in systole (contracting)
diastolic blood pressure- the lowest pressure within the blood stream which occurs between beats when the heart is in diastole (relaxing, filling with blood)

# data[].attributes.body
increase blood pressure
higher blood pressure due to more beats per minute as more blood needs to reach muscle sites as they are working

# data[].attributes.body
anticipatory rise
before starting exercise your heart rate usually increases above the resting levels this is known as anticipatory heart rate response. This is because the nerves that directly supply the heart and chemicals in the blood can rapidly alter the heart rate.

# data[].attributes.body
the anticipatory response is when the heart rate increases at the beginning of exercise. increasing the heart rate the body begins to supply oxygen and nutrients for the muscles.
the blood pressure in the arteries increases so that the muscles get more oxygen and nutrients.
vasoconstriction is the narrowing of blood vessels which caused by the constriction of the smooth muscles fibers in the wall of the arteriole.
vasodilation is the widening of the blood vessels which happens when the smooth muscles cells relax. v

cardio-vascular drift
sympathetic system working with adrenaline medulla oblongatta/SA node/av node
increase in blood pressure due to more oxygen needed.
vasoconstriction increases blood pressure meaning blood will get back to the heart quicker and leads to more blood being delivered.
vasodilation lowering temperature.

# data[].attributes.body
vasoconstriction
when the blood vessels constrict ( get smaller) to keep in heat- blood flow is directed to the muscles/ it makes the pressure higher and for the blood with the oxygen or waste products to move into/out of the system quicker
sympathetic causes this
