ADH does not exactly cause the vasoconstriction but increases the peripheral vascular resistancewhich results increases of arterial blood pressure
No. Although it is produced via the renin, angiotensin, aldosterone pathway, where angiotensin is a powerful vasoconstrictor, aldosterone itself has no vasoconstrictive properties.
norepinephrine, epinephrine and angiotensin II
Yes
High blood pressure is the most common cause of prolonged vasoconstriction in the kidney.
Yes
I believe they are stimulants due to the fact that cocaine is a stimulant and it causes vasoconstriction.
Deficiency of adh
Muscles in the blood vessels are the effectors that cause Vasodilation and Vasiconstriction.
Low levels of ADH can cause excessive urination (polyuria) followed by extreme thirst (polydipsia). A rare water metabolism disorder, called central diabetes insipidus, is sometimes the cause of ADH deficiency but low ADH doesn't not cause diabetes insipidus.
vasoconstriction of the pulmonary blood vessels
the high osmolarity of blood acts upon the osmoreceptor of hypothalmus cause the release of adh low plasma volume increase plasma cholecystokinin
If there is too little water in the blood, the hypothalamus will detect this and more ADH (Anti-Diuretic Hormone) will be produced. The increase in ADH will cause an increase in the permeability of the collecting duct in the kidney and so more water is reabsorbed into the blood. :)
Atherosclerosis can cause hypertension because it narrows the blood vessels (similar to vasoconstriction). Vasoconstriction can cause hypertension because it increases pressure and force in the vessels.
