Why brain cells swell when the blood plasma is very dilute?
Osmosis is the movement of water from a High Water (Dilute Solution) to a Low Water (Strong Solution). If blood plasma becomes very dilute with water, when it travels to the brain the brain cells will swell because the are taking on too much water. This happens because the high concentration of water (in the blood) is moving to the lower concentration of water (brain cells) making the cells swell as they are taking on too much water.
What carries needed substances to body cells?
Needed substances are carried to the body's cells by RBC's, or red blood cells. Red blood cells contain hemoglobin, a substance that allows proteins to bond to them. However WBC's(white blood cells) provide the body's cells with much needed protection.
What happens when a person has a stroke?
A stroke is any disruption to blood flow around the brain. Technically, the blood/brain barrier does not allow blood to actually enter the brain. That can be one example of a stroke, if a blood vessel ruptures and causes blood to enter the brain. In normal operation, nutrients cross the blood/brain barrier to provide for the needs of the brain. If a blood clot stops blood circulation in an area of the brain, it's also considered a stroke. Typical body function during a bleeding event is to first stop the bleeding and then initiate repairs. All of that takes place without much thought on our part. The platelets form a shield around the cut other damaged area and stop the bleeding. When this happens inside the brain, part of the brain dies. When a blood clot forms inside the brain, nutrients are stopped and that too can destroy brain cells.
Is the blood brain barrier effective against alcohol?
