Hypophyseal portal system allows the hypothalamus to have direct communication with the anterior pituitary.
The hypophyseal portal system is a network of blood vessels that connects the anterior portion of the gland and hypothalamus at the base of the brain. Two capillary beds, one in the median eminence and the other in the anterior pituitary, make up the portal system. Its principal job is to swiftly transfer and exchange hormones between the anterior pituitary gland and the hypothalamic arcuate nucleus.
The cortisol, androgens, and aldosterone hormones interact with anterior pituitary gland cells via travelling through the hypophyseal portal system. Hormonal signaling through the hypophyseal portal system enables connection between these two structures.

The two atrioventricular (AV) valves, the mitral valve (bicuspid valve), and the tricuspid valve, which are between the upper chambers (atria) and the lower chambers (ventricles). The two semilunar (SL) valves, the aortic valve and the aspiratory valve, which are in the conduits leaving the heart.
So the atrioventricular valves enables blood to spill out of the atria to the ventricles. be that as it may, regularly keeps the reverse of blood and opening. ... these valves to open and after that blood goes through from the atria into the ventricles. and afterward when the weight is developing in the ventricles.
