The name of the structure that increases the surface area of the small intestine in humans is Villi.
<h3>What are the functions of the small intestine?</h3>
The small intestine performs a key role in the digestion of undigested food which comes through the stomach. It also absorbs all the essential minerals and nutrients from the food and is used by the body.
Villi or microvilli is the structure that increases the surface area of the small intestine for food absorption and adding digestive secretions.
Therefore, the name of the structure that increases the surface area of the small intestine in humans is Villi.

The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.
More blood vessels are stimulated to vasoconstrict more than vasodilate because blood vessels contain more alpha receptors than beta receptors.
<h3>What is Vasoconstriction?</h3>
This is the process which involves the narrowing of the blood vessels through their muscle wall.
They contain more alpha receptors such as Alpha-adrenoceptor agonists than beta receptors which mimicks the effects of sympathetic adrenergic nerve activation to the blood vessels.
