Question

rigid vessels of circulatory system are ​

Answer 1

Arterioles are the rigid vessels in the circulatory system.

• Circulatory system contains blood vessels those are arteries, capillaries, and veins.

• Arteries carry blood away from the heart and arteries divided into large and small arteries.

• Smaller arteries called arterioles those are facing low blood pressure.

• Arterioles account for most of the friction in the pulmonary circulation that' why they are more rigid in the circulatory system.

Answer 2

Circulatory System

Explanation:

• Vasoconstriction is the narrowing of the veins coming about because of withdrawal of the strong mass of the vessels, specifically the huge courses and little arterioles.
• When veins tighten, the progression of blood is limited or diminished, along these lines holding body heat or expanding vascular opposition.  
• There are three fundamental sorts of veins. This immense arrangement of veins - courses, veins, and vessels.  
• Veins are a significant piece of our circulatory framework. They are liable for returning deoxygenated blood back to the heart after supply routes complete blood.
• The vena cava is the biggest vein in the body. Veins have a lot more slender dividers than supply routes.  
• There are five sorts of veins the conduits, which divert the blood from the heart the arterioles the vessels, where the trading of water and synthetic compounds between the blood and the tissues happens the venules and the veins, which convey blood from the vessels back towards the heart
