Why do females cramp when they are on they period?
The uterus is a muscle. During menses it contracts to expel menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply. This pinching off of the blood supply causes the cramping.
Which main factor allows muscle to sustain contraction even during time when the blood supply is low?
myoglobin
Why do girls have cramps during periods?
The uterus is a muscle. During menses it contracts to expel the uterine lining and menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply. This pinching off of the blood supply causes the cramping.Answer 2:I believe it's because of the shedding of the uterus lining.
How decreased blood supply effect muscle activity?
Decreased blood supply in the muscle can cause anoxia then paralysis.
Which tissue has direct blood supply epithelial connective muscle or nervous?
Muscle and Nervous tissue have the highest blood supply while connective is generally good blood supply and epithelium has no direct blood supply

What is the medical term meaning sudden contraction of a blood vessel?
Angiospasm is sudden contraction of a blood vessel. In contrast, vasoconstriction is the normal process of contraction of a blood vessel.VasoconstrictionAngiospasm
Contraction of the smooth muscle in arterioles would decrease blood pressure?
Contraction of smooth muscle in arterioles would lead to vasoconstriction, which would increase resistance to blood flow and subsequently increase blood pressure. Conversely, relaxation of smooth muscle in arterioles (vasodilation) would decrease resistance and lower blood pressure.
Where does the heart muscle receives its blood supply from?
The heart muscle is supplied by blood vessels called coronaries.
Arteries that supply the heart muscle with blood?
Yes.
What is blood supply of cardiac muscle?
Coronary arteries
Why is the direction of the wave of contraction so important in the heart?
The direction of the wave of contraction in the heart is important because it decides where the blood reflux will take place. The blood reflux could take place in the atria, or the blood from the heart could be ejected into the pulmonary artery or aorta.
