Explain 9.2 Maintaining A Balance
9.2 Maintaining a Balance Contextual Outline Multicellular organisms have specialized organ systems that are adapted for the uptake and transport of essential nutrients from the environment, the utilisation or production of energy and the removal of waste products arising from cellular activities. The basis of healthy body functioning in all organisms is the health of their cells. The physical and chemical factors of the environment surrounding these cells must remain within narrow limits for cells to survive. These narrow limits need to be maintained and any deviation from these limits must be quickly corrected. A breakdown in the maintenance of this balance causes problems for the organism.

    It provides oxygen whilst removing carbon dioxide. The airwauy begins with the nose and the mouth, continues down into the throat, into the bronchi that eventually feed into the lungs. The term respiration means the exchange of gases between body cell and the environment (Waugh & Grant 2014). After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs. As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs through the capillaries, where it is removed from the body when you exhale.Breathing supplies oxygen and elimates carbon dioxide. Our lungs inflate drawing in air between around 12 to 20 times a minute, as breathing brings oxygen into the body while carbon dioxide is exhaled.…

    he physiological functions of respiration and circulation are essential to life. If problems develop in other physiological systems, we can still survive for some time without addressing them. But if a persistent problem develops within the respiratory or circulatory systems, death can ensue within minutes. The primary role of the respiratory system is to distribute oxygen to, and remove carbon dioxide from, the cells of the body. The respiratory system works hand in hand with the circulatory system to achieve this. The term respiration includes breathing—the movement of air in and out of the lungs, also known as ventilation—as well as the transport (via blood) of oxygen and carbon dioxide between the lungs and body tissues. The heart pumps deoxygenated blood to pulmonary capillaries, where gas exchange occurs between blood and alveoli (air sacs in the lungs), oxygenating the blood. The heart then pumps the oxygenated blood to body tissues, where oxygen is used for cell metabolism. At the same time, carbon dioxide (a waste product of metabolism) from body tissues diffuses into the blood. The deoxygenated blood then returns to the heart, completing the circuit.…

    Blood enters the heart through the Superior Vena Cava which is the large vein at the top of the heart, and the Inferior Vena Cava, which is the large vein at the bottom of the heart. Blood flows into the right atrium, passes through the tricuspid valve, and makes its way into the right ventricle. It then moves through the pulmonic valve, into the pulmonary artery to the lungs.” After picking up oxygen in the lungs, the blood moves out of the lungs into the pulmonary vein, into the left atrium, through the mitral valve, and into the left ventricle that pushes blood to the body through the aortic valve. Once blood leaves the heart it is in the aorta where it flows to various parts of the body” (Whitlock, J. 2017).…

    The respiratory system and cardiovascular system work together with the same goal; getting oxygen to tissues and getting carbon dioxide out. The respiratory system is in charge of supplying oxygen to the body; air is firstly breathed in and travels into the lungs then into the left side of the heart. It is then pumped by the heart into the blood stream. Blood travels throughout the body in pathways via the assistance of the cardiovascular system. After being used by the cells a waste gas called carbon dioxide is produced. Blood carries the waste gas into the right side of the heart, from which it is pumped to the lungs. The body then breathes out the removing the waste gas from the…

    Multicellular organisms are comprised up of different types of specialised cells which are adapted to enable them to carry out specific functions. Muscle cells and epithelial cells are two examples of specialised cells within the body that are adapted for specific functions. Multicellular organisms such as mammals, the cardiovascular system is the main transport system. This particular system is powered by the heart and relies on the blood in order to transport substances such as oxygen and carbon dioxide around the body through a network of blood vessels including the veins, arteries and capillaries, the veins and arteries serve the main function of transporting blood throughout the body and arteries enabling the substances to through to the cells due to their walls being…

    Your body is an amazing machine. In fact, even the word ‘marvelous’ is not enough to describe just how amazing our bodies are. You see, your body is a product of a hundred-thousand-year evolution process. It has the power to heal itself and has the power to regenerate cells that the body thinks are necessary for you to be healthy and survive. However, as humans began to understand more fields in chemistry, biology, and technology, our bodies also become more exposed to toxins brought about by chemicals in the food we eat, radiation from the things we use, and pollutions in the air we breathe. Our bodies become so overwhelmed by the sudden increase in the toxins that surround our environment that it impairs our ability to quickly adapt to what we are experiencing. As a result, we become a little less healthy by day.…
