Circulatory System Lab Report

Introduction
The purpose of this lab is to discover the respiratory and circulatory systems of three different species: the Starfish, the Bullfrog, and the Perch. All of these species have similarities and differences and is discussed in detail in this research report. In order to determine the respiratory and circulatory systems, a dissection of the three species is needed to obtain data. Determining the systems of these species will help understand how these species work and work together in their environments in order to keep homeostasis in balance. These species have specific respiratory and circulatory systems to thrive in their environment and keep homeostasis in order.
Materials and Methods
A variety of materials were used in all

Deoxygenated blood is sent to the atrium from several organs in the frog through blood vessels and veins. The blood drains from the organs starting to cleansing process. Oxygenated blood comes from the lungs and the skin and enters the left atrium. This area is the primary gas exchange site in most amphibians. Both atria dump into the single ventricle. The ventricle is divided into two narrowly separated chambers, which reduces the mixing of the two types of bloods. When the ventricle contracts, it sends oxygenated blood to the brain from the left ventricle and then reaches the head through arteries. The skin and lungs receives pure blood from the right atrium. The skin and the lungs, oxygen can be picked up.
Conclusion
In conclusion, all of the respiratory and circulatory systems of the three different species: the starfish, the perch and the bull frog many differences. The three species are very different. The respiratory system of the starfish has no lungs or gills, the perch has gills and the bullfrog has lungs. The circulatory system of the three is also very different. The Starfish has three places where circulation occurs: the perivisceral coelom, the water vascular system and the hemal system. The Perch has one atrium and one ventricle. The bull frog has a three chamber heart: two atria and one

    The right atrium pumps blood through the tricuspid valve and into the right ventricle. The tricuspid valve would open up once blood is ready to go to the right ventricle. Once blood has reached the right ventricle, the valve would close. The right ventricle’s job is to pump blood into the pulmonary valve and into the pulmonary artery. The pulmonary valve would open up once blood is ready to travel out of the heart through the pulmonary artery.…

    Where humans use a diaphragm and frogs utilize mouth, nostrils and skin, there a various unique ways animals can extract oxygen. In conclusion the human and the frog have similarities within their system. They both require oxygen; their systems both consist of bronchi tubes, lungs, alveoli and nostrils. Small differences such as the density of the alveoli and the more complex bronchial tubing in the Homo Sapian. More differences include Humans only using lungs controlled by the diaphragm, where frogs use their skin, moist lining of mouth, muscles under jaw and…

    c) Pulmo-cutanous arch- it divides into Pulmonary artery – it receives deoxygenated blood from different parts of the body and open into lungs. Cutanous artery- it supplies oxygenated blood to skin. Venous System of frog Blood vessels, which carry the deoxygenated blood from different parts of the body to the heart, are called veins. They constitute a system called venous system. Venous system of frog can be studied under too heading A) Systemic Venous System This system includes the three large veins, which receives the deoxygenated blood from all the parts of the body and collect to the sinus venous.…

    The four chambers are the left atrium, the right atrium, left ventricle and the right ventricle. The left atrium is the collecting chamber. It collects oxygen and rich blood returning from the heart. The right atrium is also the collecting chamber for blood returning from the trip. The left ventricle is a part of the pumping chamber and it pumps blood through all body parts.…

    This is joined to a collecting duct, which carries urine through the medulla to the pelvis of the kidney. Glomerular ultrafiltration: Each Bowman's capsule is supplied with blood by an afferent arteriole. It branches inside the Bowman's capsule to form a knot of capillaries, the glomerulus. These join up again to form the efferent arteriole, which take blood away from the Bowman's capsule. The afferent arteriole is much wider than the efferent arteriole; this means that pressure is built up.…

    Fish have a two-chambered heart, the two cavities are called the atrium and the ventricle. Blood enters the heart through the atrium and then out through a ventricle. Amphibians and reptiles have a three-chambered heart that has two atria and one ventricle. Birds and mammals have a four chambered heart, two atria and two ventricles and heart valves in between heart chambers, which are flaps of tissue that prevents backward blood flow. An open circulatory system is found in arthropods and mollusks, open means that there are no vessels, so the blood is freely moving around in the animal’s body cavity or hemocoel.…

    Briefly trace and discuss the flow of blood in the human kidney. Blood passes into the kidney through the renal artery entering the glomerulus within the Bowman’s capsule. However, when traveling into the glomerulus it is split into fifty capillaries, which has thin walls. The solutes within the blood are filtered through the thin walls by the pressure gradient exiting between the fluid in the Bowman’s capsule and blood capillaries. The pressure gradient is regulated by the dilation or contraction of the arterioles.…

    The mouse has a four chambered heart, the frog has a three chambered heart, and the dogfish shark has a two chambered heart. The respiratory tract in the three animals are all different. The shark has a set of gills which extracts oxygen from the the water that passes over them, the mouse has a set of lungs though which it breathes air, and the frog has lungs to breathe air but is also able to respire through their skin when swimming. The digestive system of the frog and shark follow the same digestive tract: Food enters the mouth, goes down the esophagus, to the stomach, small intestine, large intestine, finally exiting the cloaca in the form of liquid or solid waste. The frog and the shark excrete solid and liquid waste through the same body cavity, the cloaca.…

    The septum act as the division of the sides of mammal’s heart. With the help of septum, it helps to control the rich and poor oxygenated blood to mix. These are the right and left side that contains the four chambers; right atrium and right ventricle for right side and the left contains the left atrium and left ventricles. The upper part which are the left and right atrium are the one receiving the blood meanwhile the lower chambers, the left and right ventricle, are the one that pumps the blood our of our heart as the heart contracted. On the right atrium, there is a part called superior vena cava that helps to bring the poor oxygenated blood form the upper part of our body as it travels to the right atrium.…

    When the ventricles fill with blood, they too contract together in ventricular systole. The atria and ventricles contract as units but the right and left sides act as two separate pumps. First, deoxygenated blood enters the right atrium through two large veins called the superior vena cava and the inferior vena cava. The blood is then pumped through the right AV and enters the right ventricle, the ventricle contracts and pumps blood into the pulmonary artery. In the lungs the blood gets oxygenated and returns to the left atrium through the pulmonary veins.…
