What are Smooth muscles?
Because it lacks sarcomeres and as a result, striations, smooth muscle is an involuntary non-striated muscle (bands or stripes). Its two subgroups are single-unit smooth muscle and multi-unit smooth muscle. A syncytium is the collective contraction of the sheet or bundle of smooth muscle cells that make up a single-unit muscle.
Smooth muscle makes up the walls of hollow organs including the stomach, intestines, bladder, and uterus as well as the blood and lymphatic vessels, as well as the tracts of the respiratory, urinary, and reproductive systems. The ciliary muscle, a type of smooth muscle present in the eyes, changes the shape of the lens by dilation and contraction of the iris.

According to the research, angiotensin II (A) stimulates constriction of the glomerular inlet in response to a drop in overall blood pressure.
<h3>What is angiotensin II?</h3>
It is a potent vasoconstrictor derived from the effect of angiotensin converting enzyme on angiotensin I.
It acts directly on the arterioles and by stimulating the secretion of aldosterone; for example, it increases extracellular volume and peripheral vascular resistance.
Therefore, we can conclude that according to the research, angiotensin II (A) stimulates constriction of the glomerular inlet in response to a drop in overall blood pressure.
