A fish heart is one of the simplest vertebrate hearts. The circulatory system is a single circulation, with a two-chambered heart. The blood from the fish’s atrium is pumped into the ventricle. Blood is pumped to the gills from the ventricle where gas exchange occurs in the gill filaments. This is called gills circulation. The carbon dioxide is removed while the oxygen is taken in. This re-oxygenated blood is then transport to the rest of the body’s tissues and organs to get rid of carbon dioxide and exchanging it with life-giving oxygen. This circulation is called systemic circulation. Blood is eventually pumped back into the heart’s atrium chamber where the circulation begins again. This unidirectional flow of blood creates a gradient of …show more content…
The chamber of fish heart is not separated by septum. Arteries carry blood to the heart while veins carry blood away from the heart. The fish heart only has one atrium and one ventricle. The oxygen-depleted blood from the body enters the atrium, and followed by the ventricle, and is then pumped out to the gills where the blood is oxygenated, and then it continues to circulate throughout the rest of the body. The human circulatory system is double circulation which includes the heart, veins, arteries and capillaries. The human heart chamber is separated by septum. The right part of the heart receives low oxygen blood returning back from the body. The right atrium receives this deoxygenated blood and then the right ventricle to be pumped to the lungs where the blood will be oxygenated. The oxygenated blood from the lungs is then enters the left ventricle through the left atrium and followed by pumping out into the larger body circulation (Environmental Science Investigation, n.d.). The blood transports oxygen and nutrients to the cells and removes waste products (OSU Klamath Basin Research and Extension Center, 2009). Both of them are closed circulation and heart acted as pumping organ to circulate the blood throughout the
The bond between humans and nature, it is fascinating to see how us has humans and nature interact with each other and in this case the essay The Heart’s Fox by Josephine Johnson is an example of judging the unknown of one's actions. She talks about a fox that had it's life taken as well as many others with it, the respect for nature is something that is precious to most and should not be taken advantage of. Is harming animals or any part of nature always worth it? I see this text as a way of saying that we must be not so terminate the life around us. Today I see us a s experts at destroying most around us and it's sad to see how much we do it and how it's almost as if it's okay to do and sadly is see as it nature itself hurts humans unintentionally

In the “Tell-Tale Heart” by Edgar Allan Poe, the narrator is extremely uncanny due to the reader’s inability to trust him. Right from the beggining the reader can tell that the narrator is crazy although the narrator does proclaim that he is sane. Since a person cannot trust a crazy person, the narrator himself is unreliable and therefore uncanny. Also as the story progress the narrator falls deeper and deeper into lunacy making him more and more unreliable, until the end of the story where the narrator gives in to his insanity, and the reader loses all ability to believe him.
The cardiovascular system is divided into two systems a pulmonary and a systemic. Pulmonary division- blood flows from the heart to alveolar capillaries and back to the heart. Systemic division- blood flows from heart to every capillary “except alveolar” and back to heart.
The heart is one of the most unique organs in the human body. Its capabilities and functions truly are amazing. The heart 's function is to pump blood throughout the body supplying oxygen and nutrients to tissues. The heart is the size of your fist and weighs roughly 8-12 ounces depending if you’re male or female. The heart pumps through 100 kilometers of blood vessels for blood that is 3 to 4 times thicker than water at 60 to 80 times minute for a total volume of 5 million liters a year at rest. A basic diagram of the heart includes, right coronary, superior vena cava, aorta, pulmonary artery, pulmonary vein, right atrium, right ventricle, left atrium, left ventricle. There are more in
The behavior of the narrator in The Tell-Tale heart demonstrate characteristic that are associated with people with obsessive-compulsive disorder and paranoid schizophrenia . When Poe wrote this story in 1843 obsessive-compulsive disorder and paranoia had not been discovered. However in modern times the characteristics demonstrated by the narrator leads people to believe that he has a mental illness. Poe’s narrator demonstrates classic signs throughout the story leading the reader to believe that this character is mad
A poem without any complications can force an author to say more with much less. Although that may sound quite cliché, it rings true when one examines “The Fish” by Elizabeth Bishop. Elizabeth’s Bishop’s poem is on an exceedingly straightforward topic about the act of catching a fish. However, her ability to utilize thematic elements such as figurative language, imagery and tone allows for “The Fish” to be about something greater. These three elements weave themselves together to create a work of art that goes beyond its simple subject.

The Tell-Tale Heart: An Analysis In Edgar Allan Poe’s short-story, “The Tell-Tale Heart,” the storyteller tries to convince the reader that he is not mad. At the very beginning of the story, he asks, "...why will you say I am mad? " When the storyteller tells his story, it's obvious why. He attempts to tell his story in a calm manner, but occasionally jumps into a frenzied rant.
Elaborate: The cardiac cycle of the heart is divided into diastole and systole stages. Diastole refers to the period of relaxation experienced by the atria and ventricles. Systole is the contraction of the atria and ventricles. The pattern of blood flow starts in the left atrium to right atrium then into the left ventricle and right ventricle. During its course, blood flows through the mitral and tricuspid valves. Simultaneously, the right atrium is granted blood from the veins through the superior and inferior vena cava. The job of the superior vena cava is to transport de-oxygenated blood to
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...
One important body system is the circulatory system. The systems job is to pump blood to all parts of the body. The blood circulates inside of many tubes and blood vessels which are found in your body. Blood vessels carry the blood to all parts of the body. Oxygen goes into the blood every time we take a breath. Carbon dioxide is a kind of gas. The blood carries carbon dioxide from the cells to the lungs. When a person breathes out, the body is getting rid of carbon dioxide. Your circulatory system works twenty-four hours a day, seven days a week. It even works when you are sleeping. The circulatory system delivers food, fluids and chemicals to cells throughout your body. It helps to clear your body of waste and carries cells that fight diseases. If your circulatory system would stop working, your cells would starve. Sometimes a doctor would give a patient a vaccine directly into the circulatory system so the medicine should travel to the parts of the body that need it. The circulatory system is made up of three main parts: the heart, the blood vessels, and the blood. The two main kinds of blood vessels are arteries and veins. There are also smaller vessels called capillaries. Arteries and veins are connected by capillaries. A heart of a human is a muscle. The heart has a left side and right side. On the right side, blood enters the heart from the body and then goes from the right side of the heart and to the lungs. In the lungs, it picks up oxygen and returns to the left side of the heart. The oxygen and the blood are then pumped to the body. The heart contains valves. The valves function is to keep the blood flowing in one direction. Each side of the heart is divided into two parts. The upper chamber is called an...
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
The Heart is a very important organ in the body. It is what keeps your blood flowing and your organs going. It is a tireless muscle that pumps more than two thousand gallons of blood every day. The blood that is pumped is filled with nutrition and oxygen (Colombo 7). It travels through out your body in less than sixty seconds. So it needs to be taken extra good care of. When abuse is put on the body, the heart’s performance is not at its best. The Heart is a major organ that needs loving and care. Everyone has only one and by abusing it, they are cutting their live span little by little. People can live their lives freely but how they choose to live them could be the difference between life and death.
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
