Grasshopper Circulatory System Essay

11.2 The Circulatory System The circulatory system is made up of multiple different organs, and it's main function is transportation. The system allows blood to circulate, which transports oxygen, hormones and nutrients as well as picking up waste. The elements of the system include; The Heart The heart acts as a muscular pump which is divided into 4 different chambers, the heart's main function is to pump the blood around the body. It pumps deoxygenated blood through the veins, to the…

A) Explain why transport systems are required in the body? The reasons as to why transport systems are required in the body is because it allows the body to be able to respire and be able to get all that it needs to maintain the same state, for example, oxygen throughout the body as well as nutrients to the cells in the body. An example of a transport system is the Respiratory system. This system is required in the body as it helps the body to take in oxygen, this can be done through the lungs,…

Over the years, biologists have carried out experiments to explore the differences in animal hearts. With regards to this experiment at hand, the differences were explored between mammalian and amphibian hearts. This experiment also helps us determine the effects of external, biological factors and pharmacological substances on the contraction of the heart. The following will serve as an overview of the structure and functioning of amphibian heart. A frog heart has three chambers (two atria and…

Breathing air in and out is the first step to the respiration process. Respiration is a series of metabolic reactions and processes that take place within the cells of organisms. The organisms store biochemical energy within adenosine triphosphate (ATP) molecules. For the process to being, we must first draw air into our lungs. The lungs muscles contract and expand the chest cavity, causing a negative or hypotonic pressure within the pleural cavity. The hypotonic pressure then forces the lungs…

Lungs The lungs are important part of our bodies. These lungs represent organs that filled with air. They locate in each side of the chest. A thin tissue layer covers the lungs; this tissue is called the pleura. The importance of lungs is to inhale the air and exhale it (1). In order to protect our lungs, we have to learn how our lungs work. First of all, we breathe the air by the nose or the mouth, then drawn down through the throat into the windpipe (trachea). Tracheasplits out into two tubes…

The heart’s role for the entire body is not only limited to pumping blood. It also needs its own blood supply to be able to perform its several functions. The process of the heart managing its own blood supply is known as coronary circulation. The walls situated in the heart have systemic blood vessels. These exist to meet the needs of the heart for blood supply. Oxygenated blood is brought to the myocardium via the left and right coronary arteries. They are also responsible for bringing the…

I chose to take a brief look at coronary procedures involving grafts. To answer the question first we need to understand some of the differences in veins and arteries. The arteries in the systemic system, deliver oxygenated blood from the heart, in a high pressure low volume stream to the capillaries found throughout the body. The systemic veins carry the deoxygenated blood from the capillary beds in a low pressure, high volume, valve controlled flow, back to the heart. From there, the heart…

The Cardiovascular System is composed of the heart and the blood vessels. The main function of the cardiovascular system is to pump blood around the body. The cardiovascular System is divided into two parts, the systematic circuit and the pulmonary circuit. The systematic circuit contains oxygenated blood and the pulmonary blood contains deoxygenated blood. In order to prevent oxygenated and deoxygenated blood from mixing there is a structure called an interventricular septum. The septum…

Describe the structure and function of the cardiovascular system Blood vessels Arteries, veins and capillaries takes blood and nutrition to the muscles and back from the heart. Arteries take the blood that has O2 in it away from the heart under high pressure with a small diameter and it has thick muscular walls, and veins take the blood back to the heart under low pressure it has a medium thickness to it and a large diameter because it has valves to stop the blood flowing backwards.…

In the respiratory system you can found nose which is a pathway for air and this is where the oxygen get into the lung and carbon dioxide into the air .Pharynx also known as throat is an other way which air can also enter into the lungs through the mouth. Air also enters into the larynx also known as voice box. It have two main functions as it is a passageway for air to enter into the lungs and a source of vocalization. The epiglottis is a tissue a flap-like cartilage structure contained in…
