BTECH Unit 6A biologyThe affect of caffeine on heart rate
,Why am I performing this
experiment
• The heart is a vital organ that moves blood throughout the body,
giving cells nutrients and oxygen while also removing waste. A
number of things, including physical activity, stress, and specific
substances, can affect the heart rate, which is the number of times
the heart beats per minute. Particularly, Numerous substances,
including caffeine, nicotine, and alcohol, have been shown to have
different effects on heart rate. The reason why I am studying this
subject is to have an understanding of the effect of substances on t
heart rate can be used to make an informed medical treatment
decision.
,Topic of interest : how does caffine
affect heart rate in daphnia
• How caffeine affects the heart rate of daphnia is the subject of interest.
Small aquatic crustaceans known as daphnia, also called water fleas, hav
long been used as a model organism in toxicology and physiology resear
These tiny creatures are particularly useful for studying the effect of
caffeine on the heart rate because of their transparent exoskeletons, wh
make it simple to observe their internal organs, including their hearts.
Daphnia can be exposed to various substance, and researcher can monit
changes in the heart rate and use this data to better understand how the
substances can affect human and other larger organisms. This makes
daphnia the perfect model for researching how different substances affe
heart rate and identifying potential health risk to human.
