Arterioles in the villi of the small intestine play a crucial role in supplying oxygenated blood to the intestinal tissues and facilitating nutrient absorption. They regulate blood flow through vasoconstriction and vasodilation, ensuring that the villi receive adequate blood supply based on the metabolic needs during digestion. Additionally, the arterioles are involved in the exchange of nutrients and waste products, contributing to the overall efficiency of the digestive process.
What else can I help you with?
What is the function of pulmonary arteriole?
The pulmonary arteriole is responsible for carrying low-oxygen blood from the heart to the lungs, where it undergoes oxygenation and then returns to the heart. This oxygenation process is vital for supplying oxygen to tissues and organs throughout the body.
What the arteriole leads into the glomerulus?
The afferent arteriole leads into the glomerulus, which is a bundle of small blood vessels located within the Bowman's capsule in the kidney. This is where blood is filtered to form urine in the process of urine formation.
Does the efferent arteriole take blood to the nephron?
No, the efferent arteriole carries blood away from the glomerulus in the nephron. Blood entering the glomerulus via the afferent arteriole is filtered, and the efferent arteriole carries blood containing the filtered substances away for further processing in the renal tubule.
What two things does every villus have?
Every villus has a network of capillaries and a lacteal.
Why is the lining of the villus moist?
The lining of the villus is moist because it contains a layer of mucus that helps lubricate the passage of food and protects the villus from friction or damage. This mucus layer also aids in the absorption of nutrients by keeping the surface of the villus moist, facilitating the movement of molecules across the epithelial cells.
Function of arterioles?
An arteriole is a very small blood vessel that leads an artery to a capillary. The main function of the arteriole is to change the blood pressure and velocity of blood flow.
What is the size of the arteriole?
what is the actual size of arteriole
What is the meaning of villie?
pl. of Villus., of Villus
What is the blood vessel that drains blood from the glomerulus?
Efferent arteriole takes the blood away from the glomerulus
What is the plural word for villus?
The noun 'villi' is the plural form of the singular noun 'villus'.
Where does the transition from an afferent arteriole to an efferent arteriole occur?
glomerulus. The afferent arteriole leads to a ball of capillaries called a glomerulus which is enclosed in a nephron structure called the glomerular capsule. Blood leaves the glomerulus by way of the efferent arteriole.
What arteriole supplies blood to the capillaries of the glomerulus?
afferent arteriole

What is the function of pulmonary arteriole?
The pulmonary arteriole is responsible for carrying low-oxygen blood from the heart to the lungs, where it undergoes oxygenation and then returns to the heart. This oxygenation process is vital for supplying oxygen to tissues and organs throughout the body.
Which arteriole supplies blood to the capillary of the glomerulus?
The afferent arteriole supplies blood to the capillaries in the glomerulus of the kidneys. The efferent arteriole takes the blood away from the glomerulus.
Is an arteriole a small artery?
Yes, it can be easily said that an arteriole is a miniature form of an artery.
What the arteriole leads into the glomerulus?
The afferent arteriole leads into the glomerulus, which is a bundle of small blood vessels located within the Bowman's capsule in the kidney. This is where blood is filtered to form urine in the process of urine formation.
