What are the effectors that cause vasodilation and vasoconstriction?
Muscles in the blood vessels are the effectors that cause Vasodilation and Vasiconstriction.
Differences between vasodilation and vasoconstriction?
Vasodilation is relaxation of blood vessels leading to increase in lumen size. Vasoconstriction is contraction of blood vessels leading to decrease in lumen size.
Do veins have the ability to go through vasoconstriction and vasodilation?
Yes, the veins have the ability to go through the vasoconstriction and vasodilation. This also applies to the other elastic tubular channels like the capillary and the arteries.
When is vasodilation bad?
Never. Unless you're bleeding, but if you're bleeding the body will undergo vasoconstriction not vasodilation so the answer is never.
What is the importance of negative feedback in the control of vasodilation and vasoconstriction?
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.
Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?
Low oxygen levels cause vasodilation in systemic arterioles.High oxygen levels cause vasodilation in capillaries in the lungs.
Does the sympathetic nervous system cause vasoconstriction?
Yep! The sympathetic nervous system causes both vasoconstriction & vasodilation. During "fight or flight" you need more O2/blood delivered to your skeletal muscles. The SNS causes vasodilation in skeletal muscles. The other organs, of the body (like digestive organs) are not needed for "fight or flight" survival. The SNS causes vasoconstriction in these organs.
Why does vasodilation and vasoconstriction happen in a cycle?
Vasodilation and vasoconstriction occur in a cycle to regulate blood flow and maintain homeostasis in the body. Vasodilation refers to the widening of blood vessels, which allows for increased blood flow and delivery of oxygen and nutrients to tissues. Vasoconstriction, on the other hand, is the narrowing of blood vessels, which reduces blood flow and conserves heat and nutrients. These processes are dynamically regulated based on various factors such as tissue oxygen levels, metabolic demands, and body temperature.
In what body part would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?
LUNGS
What produces vasoconstriction?
Peripheral vasoconstriction is the tightening of the blood vessels, particularly the arteries. It is caused by smoking, drinking alcohol and coffee, as well as the intake of medicine such as antihistamine.
What does the root vaso mean?
The root "vaso" means vessel or duct. It is commonly used in medical terms related to blood vessels, such as vasodilation (widening of blood vessels) or vasoconstriction (narrowing of blood vessels).
Which organ blood-flow pattern results in low oxygen levels causing vasoconstriction and high oxgyen levels causing vasodilation?
The lungs
