Okay class we are done for the day! Don't forget your homework!
Woah I am so dizzy!
Let's figure out why he got so dizzy!
When you get up too quickly your blood pressure changes. Your blood pools in your legs, which lowers the amount of blood being pumped from your heart to your brain. Low blood flow to the brain causes dizziness and other symptoms.
The Circulatory system is at work during this time
To compensate, the nervous system quickly increases the heart rate and constricts blood vessels. The blood pressure is then quickly returned to normal, which helps take away the symptoms produced by the low blood pressure.
The nervous system is working at this time, but to be more specific it is the autonomic nervous system.
Both the nervous and circulatory systems work to bring his body back to a balance.
I feel so much better now! I am off to football practice!
