SummaryOne of the most important organs in the body is the heart. Of course, this organ is of great importance not only in humans but in all vertebrates. Blood, which carries nutrients, oxygen, and wastes from organ to organ within the body is pumped by the heart. Without the heart’s pumping action, blood would simply remain stagnant within the vessels of the body, and any vertebrate in this condition would die off very quickly.
Table of Contents- While the heart is essential to all vertebrates alike, it is important to note that there are some stark distinctions between the hearts of different vertebrates.
- Although the heart is able to initiate its own action potential and make itself beat, there are sympathetic and parasympathetic neurons that innervate it.
- As compared to the control, adding epinephrine sped up heart rate but, according to the readings, decreased contractile strength.

SummaryThe heart is an integral part of the cardiovascular system in the body of vertebrates. It provides the pressure needed for the blood to be pumped to different parts of the body. The heart maintains the flow of blood throughout the whole cardiovascular system. This in turn allows all the separate parts of the body to be energized with oxygenated blood, maintaining a stable internal environment.
The heart plays essentially the same role in all the animals which posses it, however its structural anatomy varies somewhat from species to species. Amphibian hearts have three chambers which include the left atrium, right atrium and a single ventricle.

Table of Contents- Introduction
- The heart plays essentially the same role in all the animals which posses it, however its structural anatomy varies somewhat from species to species.
- In order for the heart to function properly it must sustain a certain rhythm.
- Certain drugs can affect the rhythmic beating of the heart in various ways
- When the sympathetic branch of the autonomic nervous system is stimulated Norepinephrine is released, increasing both the heart rate and the strength of the cardiac muscle contraction
- As the cardiac cycle progresses electrical impulses travel throughout the cardiac muscle, producing electrical currents
- My group and I followed the procedure as written in Foundations of Biology
- Discussion
- In order to accurately understand the mechanisms of the heart one must look at the electrical portion of the readings (ECG
- In retrospect our hypothesis did hold up to an extent
