aldosterone
ACTH stands for adrenocorticotropic hormone. It is a hormone produced by the pituitary gland that stimulates the adrenal glands to produce cortisol, a stress hormone. ACTH plays a key role in the body's response to stress and helps regulate the body's metabolism, immune response, and blood pressure.
Oxytocin and vasopressin are neurohypophysis hormones synthesized in the neurons of paraventricular and supraoptic nuclei of the hypothalamus and travel to the terminals in the neurohypophysis for storage and release into the vascular system. Oxytocin stimulates milk ejection and uterine smooth muscle contraction at parturition; while vasopressin affects water retention and blood pressure.

If your blood vessels dilate whithout an increase in your heart rate, your blood pressure can drop dramatically. exercise stimulates your heart rate to increase and also hormones such as Nitros oxide (NO aka. Viagra) causes vasocontriction or the contracting of blood vessels so that blood pressure rises.
As such there is no special reason to have high blood pressure in teens except psychological stress. Stress hormones will rise the blood pressure.
Vasodilation is the widening of blood vessels, resulting in increased blood flow and decreased blood pressure. Vasoconstriction is the narrowing of blood vessels, leading to decreased blood flow and increased blood pressure. Both play important roles in regulating blood flow and maintaining homeostasis in the body.

Plant hormones balances the hormones of humans. For example, soybean (Glycine max) affect the level of HDL, also affect the level of blood pressure and sex hormones estrogen due the phytoestrogen concentration of the plant.
The kidneys secrete a variety of hormones, including erythropoietin, and the enzyme renin. Erythropoietin is released in response to hypoxia (low levels of oxygen at tissue level) in the renal circulation. It stimulates erythropoiesis (production of red blood cells) in the bone marrow. Calcitriol, the activated form of vitamin D, promotes intestinal absorption of calcium and the renal reabsorption of phosphate. Part of the renin-angiotensin-aldosterone system, renin is an enzyme involved in the regulation of aldesterone levels.
Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges.
