CO2 causes vasodilation of the cerebral artery. The mechanism is pressumed to be due to direct effect of CO2 on the wall of the blood vessels.
Anecdotal/clinical evidence:
In emergency head injury, raised intracranial pressure can be treated by hyperventilating the patient. Hyperventilation reduces the PaCO2 in the blood. This causes vasoconstriction of the cerebral vessels and reduces ICP almost immediately.
What else can I help you with?
What type of blood does the pulmanary artery carry?
The pulmanary artery carries oxygen poor blood.
What factor affects the solubility of carbon dioxide in soda?
The two main factors that affect solubility of carbon dioxide in soda are temperature and pressure.
What are the factors that affect plant growth?
Light, water, carbon dioxide.
Does carbon dioxide affect the production of high energy sugars?
yes
How does respiration affect the amount of carbon dioxide in the atmosphere?
Respiration, breathing, has no effect on the amount of carbon dioxide in the atmosphere. This is part of the natural carbon cycle. Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide that has been hidden away for millions of years. This extra gas is increasing in the atmosphere.
What are the only artery in the body rich in carbon dioxide?
The Pulmonary Artery
Does carbon dioxide affect humans?
We exhale carbon dioxide or called CO2
The only artery in the body rich in carbon dioxide?
Pulmonary by Luvleen Brar :)
What are the three differences between the composition of blood in pulmonary artery and pulmonary vein?
Pulmonary artery 1. No oxygen 2. A lot of carbon dioxide Pulmonary vein 1. Lots of oxygen 2. No carbon dioxide
What artery takes blood to the lungs to pick up carbon dioxide?
The artery that carries blood from the heart to the lungs to pick up carbon dioxide is the pulmonary artery. It transports deoxygenated blood from the right ventricle of the heart to the lungs, where gas exchange occurs, allowing carbon dioxide to be expelled and oxygen to be absorbed. After this process, the oxygenated blood returns to the heart via the pulmonary veins.
Why does the Pulmonary artery have blood filled with Carbon dioxide in it?
I put this question up here before I registered.The simplest answer I can find is Celluar respiration puts out carbon dioxide which is carried through the blood in the Pulmonary artery to the lungs.Am I right though?
What determines in which direction carbon dioxide and oxygen will diffuse in the lungs?
pressure difference between carbon dioxide and oxygen level between pulmonary artery and alveolar space
What part of the circulatory system carries either oxygen or carbon dioxide?
the parts of the are the artery and vein.
What gas is carried by most arteries?
Oxygen. The pulmonary artery carries carbon dioxide instead.
Which blood vessels has the lowest concentration of carbon dioxide?
capillariesVena CavaPulmonary artery
Does concentration of carbon dioxide affect the pH?
yes
How does coal affect people in society?
with carbon dioxide
