What happens when the heart relaxes?
It is in its diastolic phase.
What happens to the density of a given substance if you increase the amount of the substance that you have?
Nothing happens if the volume is also allowed to increase.
What happens to your heart rate when you excercise?
Depending on how light or heavy exercise is will depend on the change that occurs. Typically during exercise heart rate will increase. This is in order to increase blood flow to the working muscles to allow for increased respiration - in order for the muscles to work efficiently. Therefore the more strenuous the exercise, the more your heart rate will increase. Blood pressure will also increase during exercise and again depends on intensity levels. During exercise such as running/cycling/swimming systolic pressure will increase progressively whereas diastolic pressure will increase only slightly. During weight lifting exercises, both systolic and diastolic pressures will rise. Obviously these effects will vary from person to person, depending on age, gender, exercise level, exercise intensity etc. etc.
What happens if you do not replace the thermostat?
Not having a thermostat fitted will result in the engine running much cooler, usually accompanied by a loss of efficiency and performance as the engine won't be able to reach its optimum running temperature.
What happens if the heart receives more sympathetic stimulation than parasympathetic stimulation?
increase its rate and force of contraction
What happens to end diastolic volume when an increase in contractility is not accompanied by an increase in heart rate?
end diastolic volume is decreased
What happens when the heart relaxes?
It is in its diastolic phase.
What happens to resting diastolic blood pressure as an adaptation to regular exercise?
Diastolic blood pressure is when the heart is refilling with blood after pumped oxygenated blood to the working muscles; this is the relaxation phase. An adaptation to regular cardiovascular exercise is an increase in the hearts efficiency in doing this. Therefore, as an adaptation to exercise, diastolic blood pressure either decreases slightly or doesn't change. This is because the heart has longer to refill the atrium so it isn't under as much pressure.
Why does diastolic blood pressure decrease during exercise?
Diastolic pressure remains constant or less than normal regardless of exercise intensity due to decreased peripheral resistance as increased metabolism will cause vasodilatation so decrease resistance due toABP = COP X Peripheral resistance
What happens to the BP of a poorly-conditioned individual after a vigorous exercise compared to a well-conditioned athlete?
"BP is indirectly indicated by intensity or exertion levels. The systolic BP is expected to rise because of the increase in cardiac output. Diastolic BP is expected to remain equivalent to resting levels or decrease during exercise indicating an increase of vasodilation and an opening of the capillary beds." (Collegetermpapers)
What happens to the strength of a base as the pH value increase?
Also increase.
What happens if your blind?
It can increase your hearing
What happens to the rest of the energy?
increase
What happens to cells during frostbite?
The cells will freeze, and likely die, especially when accompanied by rubbing when frozen.
What happens when your cat hisses at you?
Normally you would hear a hissing sound accompanied by your cat being angry
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
What happens in a circuit if you increase the voltage of the battery driving it?
The power in the circuit will increase.
