Circulatory System of Frogs vs. Circulatory System of Humans The circulatory system of a human compared to that of a frog is different due to the number of chambers each contains. A frog’s heart has three chambers (two atria‚ and a single ventricle)‚ whereas a human’s has four (two atria‚ and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin. Both

Chemical and Environmental Effects on the Heart Introduction The heart is the centerpiece of the circulatory system‚ its muscular contractions allow for the timely delivery of essential gases and nutrients to virtually all cells of the body. The pressure created by the heart also plays a vital role in eliminating wastes through organs such as the kidney‚ thus the heart delivers and helps maintain nutrient and waste composition throughout the body. The heart‚ like all muscle cells‚ releases ionic

Charles Darwin’s idea of evolution can be applied to this nursery rhyme. The nursery rhyme‚ Five Little Speckled Frogs‚ continues to repeat itself‚ however‚ each time there is one less frog.

The purpose of this experiment is to examine the results of stimulation on a frog’s sciatic nerve by looking at its compound action potential‚ the conduction velocity‚ and by quantifying the total and absolute refractory period between the nerve at room and cold temperature. An oscilloscope‚ preamplifier‚ and stimulator were used to stimulate the frog’s nerve located in the nerve chamber. Threshold voltage was determined by stimulating the nerve at increasing voltages until a compound action potential
