Define the term collateral blood flow and describe how this and other factors affect the development of a stroke?
When a collateral vessel on the heart enlarges, it lets blood flow from an opencoronary artery to an adjacent one or further downstream on the same artery. In this way, collateral vessels grow and form a kind of "detour" around a blockage. This collateral circulation provides alternate routes of blood flow to the heart in cases when the heart isn't getting the blood supply it needs. When an artery in the brain is blocked due to stroke or transient ischemic attack (TIA), open collateral vessels can allow blood to "detour" around the blockage. This collateral circulation restores blood flow to the affected part of the brain.
4 factors that affect blood pressure?
There are four factors that affect the blood pressure. The things that can affect blood pressure are stress, genetics, a high salt intake, and exercise.
What is the significance of hypertension in the development of stroke?
Hypertension is related to the increased risk of stroke. A stoke happens when a blood vessel is blocked, thereby having no oxygen transported to the oxygen-dependent brain cells. Hypertension will risk the blockage of the blood vessels through narrowing of the blood vessels.
What diseases affect the risk of stroke?
Stroke risk is increased for people with diabetes, heart disease (especially atrial fibrillation), high blood pressure, prior stroke, or TIA. Risk of stroke increases tenfold for someone with one or more TIAs.
Do all areas of the body have collateral circulation?
Collateral circulation is the formation of new blood vessels to circulate blood. Not all areas of the body have collateral circulation since it is formed by normally closed arteries.
What organisms does a stroke affect?

A stroke is a rupture of a blood vessel in the?

How does a Transient Ischemic Attack mini-stroke affect all other body systems?

Does paranoia lead to a stroke?

What does the abbreviation CVA mean?
A CVA is a common acronym standing for cerebro-vascular accident another term for a stroke.A stroke is defined as a loss of brain function usually caused by an affect on the flow of blood to the brain. The type main types of CVA/stroke are haemorrhagic stroke and occlusive (blockage) stroke.
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
Can a healthy diet prevent me from suffering a heart attack or stroke?
A heart attack affects the cardiac system, including the heart and blood. A stroke occurs when there is a blood clot in the brain that prevents adequate blood flow. A diet that is high in fats can cause plaque to build in the veins of the body and affect both the brain and the heart.
