What else can I help you with?
What would happen if your blood flow was reversed?
If the entire blood flow was reversed, you would die. Arteries and veins have different functions and structures. Arteries bring blood, oxygen, and nutrients to cells, and veins take waste away from cells. Veins have valves in them to keep the flow going the correct way. The body couldn't function is the blood flow was reversed.
Why do my scars turn purple when I'm cold?
When you are cold, your blood vessels constrict, reducing blood flow to the skin. This can cause scars to appear purple or darker in color because of the decreased blood flow to the area.
What is cerebral blood flow regulated by?
Cerebral blood flow is regulated by a combination of factors including blood pressure, carbon dioxide levels, neural activity, and metabolic demands of brain tissue. Specialized structures in the brain called the blood-brain barrier and autoregulation mechanisms help maintain a consistent blood flow to meet the brain's energy and oxygen requirements.
What is an imaging technique that produces colors to indicate the degree of metabolism or blood flow in the brain is called?
The imaging technique that produces colors to indicate the degree of metabolism or blood flow in the brain is called functional magnetic resonance imaging (fMRI). It measures brain activity by detecting changes in blood flow.
An anastomosis that allows communication between the posterior and anterior blood supplies of the brain?
The Circle of Willis is an anastomosis located at the base of the brain that connects the anterior and posterior blood supplies. It helps ensure continuous blood supply to the brain by allowing blood to flow between the carotid and vertebrobasilar systems. This configuration helps maintain brain function in the event of a blockage or reduced blood flow in one of the systems.
Did Cheyne stokes syndrome is an altered state of consciousness due to decreased blood flow to the brain?
yes
What is one result of decreasing blood flow to the heart or brain?
The correct answer is faintness, dizziness.
Why does locking knees cause fainting?
Locking the knees can restrict blood flow to the brain, leading to a drop in blood pressure and causing fainting. This happens because the body has difficulty pumping blood back up from the legs when the knees are locked, which can result in decreased blood flow to the brain.
Why does decreased pulmonary blood flow cause cyanosis?
Decreased pulmonary blood flow alone does not cause cyanosis. It is when decreased pulmonary blood flow is associated with right to left shunting (ie Tetralogy of fallot) that it is associated with cyanosis.
Is there more blood flow to the kidneys in the elderly?
No, there is decreased blood flow to the kidneys with age.
What would experience a decreased blood flow during exercise?
no it actually stimulates blood flow
What is the difference between a stroke and fainting?
A stroke occurs when a blood clot blocks an artery or a blood vessel breaks, blocking blood flow to the brain; brain cells begin to die and brain damage occurs. On the other hand, when someone "faints" they do have a decreased blood flow to the brain, but it is caused by a temporary unconsciousness.
What is decreased blood flow associated with a stroke?
ischemia
Decreased peripheral resistance to blood flow?
Decreased peripheral resistance to blood flow is typically associated with vasodilation, which occurs when the smooth muscle in blood vessel walls relaxes. This can lead to increased blood flow to tissues and decreased blood pressure. Vasodilation can be caused by factors such as the release of nitric oxide or certain medications.
How can a lack of oxygen cause strokes?
A lack of oxygen to the brain, known as hypoxia, can lead to strokes by causing damage to brain cells. This can disrupt the normal functioning of the brain, leading to a decreased blood flow and potentially causing a blood clot to form, which can then block a blood vessel in the brain and result in a stroke.
Decreased blood flow to cardiac muscle that only injures the tissue creates a condition known as what?
Myocardial infarction is the decreased blood flow to cardiac muscle that only injures the tissue.
What is the term for decreased blood flow?
Ischemia is the medical term for decreased blood flow. Ischemia limits the supply of oxygen to tissues.
