by the nervous system and the endocrine system. Homeostasis is described as a ‘negative feedback system’. This just basically means that the system is able to take remedial action to preserve a constant environment. Homeostasis is in charge of maintaining the constant level of many body functions, such as heart rate, breathing rate, body temperature and blood sugar levels. (Rasheed, Hetherington and Irvine, 2010). Heart rate Roles of internal receptors, autonomic nervous system-sympathetic and

It is commonly known that caffeine, a nitrogenous organic compound generally found in coffee, tea, and cacao, has immense effects on the heart rate of living organisms. Similarly, it is known that those effects - such as a higher alertness, decreased fatigue, anxiety, jitteriness, etc. - are both pros and cons of caffeine consumption. While caffeine can have a slightly different effect depending on the organism that consumes it, the outcome of intake is primarily identical. Caffeine mimics some

The autonomic nervous system, ANS for short, is a subdivision of the peripheral nervous system; which is responsible for regulation of homeostasis and coordinates the functions of the cardiovascular, respiratory, digestive, excretory, and reproductive systems. The ANS is like the Somatic Nervous System as they both have afferent and efferent neurons; while in the ANS, the afferent pathways originate in visceral receptors and efferent pathways attach to the visceral effector organs. ANS can be further
