The Taxonomy of a Frog Essay

These can be divided structurally into 2 parts, the upper respiration system which consists of nose and pharynx and the lower respiratory system which consists of larynx, trachea, bronchi and lungs.

Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive.

Secondly, the human body, crayfish, earthworm, and frog also have many similarities and differenced of how their respiratory system works. The crayfish respiratory system is the least complex. Crayfish have gills, which are used to release carbon dioxide and to pick up oxygen, by having a constant flow of blood. Frogs consist of nostrils and larynx, which opens up two lungs. The walls of the lungs are filled with capillaries. Capillaries are

The worm, crayfish, and the frog have many of the same distinct features as well as some that are not. Throughout the dissection days, i’ve observed many things that relate to the human body system like the digestive system, respiratory, reproduction, etc. But, there are also many things that don’t match with one another. There are many things I can talk about the similarities and differences between all these animals to the human system, but i'll keep this short so it won’t be a whole 7 page essay. I will be talking about mostly about the similar and differences to each one that is compared to the human body system or mostly compared to one another.

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

When society thinks about starfish, perch, chordate, and fetal pig they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of all animals before going into major detail about them. According to the online website named dictionary.com, Starfish are any echinoderm of the class Asteroidea, having the body radially arranged, usually in the form of a star, with five or more rays or arms radiating from a central disk; asteroid (dictionary.com). It is known that a chordate is an animal belonging to the phylum Chordata, composed of true vertebrates and animals having a notochord (dictionary.com). According to research, a fetal pig is an animal in the phylum Chordata and class Mammalia (dictionary.com). A perch is known to be a certain kind of fish with very spiny fins (dictionary). Starfish, perch, chordate, and fetal pig are some very interesting animals that possess some exclusive qualities both similar and different.

The whistling tree frog does not have as many infected or dead frogs as scientists expected. Researchers theorized that the frog has evolved slightly or those who were infected as juveniles survived and became immune. Their habitat is also play a role in their

In the case of the cricket dissection it was fairly easy to see how close together the organs were and intertwined the were with each other to perform daily activities for the cricket. For example, the seminal receptacle and the ganglia are stacked right on top each other literally occupying the same space which leads me to be believe that they are working together to carry out the function of life that is reproduction for the cricket especially see as it was a female cricket that I was dissecting. Another example for the cricket is the connection between the respiratory system and circulatory system as it pertains to working together to help the cricket breathe properly. The connection between these two systems was little harder to see as

A healthy heart pumps blood continuously through the circlutory system. It’s normal size is a little larger than a fist. The heart has four chambers, two on the right and two on the left. The two upper chambers are called the atria and the lower two are known as the ventricles. The right atrium takes in deoxygenated blood from the rest of body and sends it back out to the lungs through the right ventricle where the blood becomes oxygenated. Oxygenated blood travels from the lungs to the left atrium, then onto the left ventricle, which pumps it to the rest of the body.

1.Even though salamanders don’t have lungs, they are still able to get oxygen through their skin and mucous membrane located in their mouth and throat. In order to obtain oxygen not only must these surfaces remain moist at all times but diffusion must also occur. The salamander’s small size and thin epithelium skin allows the salamander to have a high surface area to volume ratio which allows a greater diffusion of water and oxygen. On the contrary, humans have a tracheal branched system which also provides a high surface area to volume ratio.

Due to experimentation with the zebrafish, scientists have been able to gain insight into the formation and function of individual tissues, organ

The heart is what keeps all living breathing species alive, animals or humans. If the heart was to shut down but the nervous system continued and was active, it would not matter. The entire body would shut down because once the supplier no longer delivers what is needed; organs will no longer function correctly, therefore causing irreversible damage. Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the oxygen-rich blood goes to the left atrium and then through the mitral valve to the left ventricle where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a complicated process that would take hours or minutes is actually done in a matter a seconds.

Frogs, toads, caecilians, and salamanders are the members of the class Amphibian (amphi- meaning “on both sides” and bios- meaning “life”). These members always require water for reproduction. Most Amphibians undergo metamorphosis, which is a usually degenerative pathological change in the structure of a particular body tissue. And, in the case of Amphibians, it is the changing of a tadpole into
