Respiration

A. Nitric oxide is an odorless gas that plays an important role in the regulation of pulmonary vasomotor tone. As inhalation occur, NO is diffused from the endothelium into the smooth muscles of the pulmonary vessel and stimulates soluble guanylate cyclase which converts GTP to cGMP. An increase in cGMP relaxes the smooth muscles and produces vasolidatory effects which increase the blood flow to well-ventilated areas with elevated vasomotor tone. Beneficial effects of inhaled NO include decrease…

Respiration is a process, which conducts the circulation of air between the lungs and the external environment. Two main mechanisms involved in the respiration process is the act of inspiration and expiration. Inspiration involves the inhaling of oxygen into the lungs. Expiration involves the exhalation of carbon dioxide into the external environment. Respiration is important to human body because it is a major contributor to speech. As mentioned in the paragraph above, a variety of muscles…

This lab will be testing the respiratory system. The respiratory system is how the body gets oxygen and gets rid of carbon dioxide. The body needs oxygen to perform cellular respiration and make ATP. The body also needs to get rid of carbon dioxide because when carbon dioxide builds up in the body it lowers blood pH(Kellman, 2000). Oxygen is taken in when the body inhales, it is taken through the lungs to the alveoli, where it is transformed into the hemoglobin and transported around the body…

Abstract Respiration for life and respiration for speech while similar are very different. The two roles of the respiratory use the same structures and muscles yet they have very different outcomes. One results in breathing which is vital to life while the other produces sounds that make communication between two individuals easier. Therefore, the structures and muscles in the respiration for life help to deliver oxygen to the different parts of the body. Along with this, the main function of…

Respiration (Growth vs Maintenance Respiration) Plant respiration is the metabolic link between gross primary productivity and net primary productivity. It is also a large component of a plant's carbon budget; perhaps typically 50-70% of carbon assimilated in gross primary productivity is released back to the atmosphere as CO2 during subsequent plant respiration (Amthor and Baldocchi, 2001). Growth is the conversion of temporary pools of substrates such as carbohydrates and amides into new…

Lower tract acute respiration infections (LT-ARI) has been estimated to cause 75% of all acute illnesses and are said to affect infants and young children worldwide. New respiratory viruses such as: human metapneumovirus (hMPV), new subtypes of human coronaviruses (hCoV), and bocavirus (hBoV), have been linked to LT-ARI. A common factor that affect LT-ARI studied in this experiment is age, although the prevalence is truly unknown. A study was conducted to aim an estimate prevalence of viral…

mechanism of converting sunlight and CO2 into energy in the form of organic material (Hohmann-Marriott and Blankenship 2011). Plant respiration is the process of using energy and oxygen to produce CO2 (Gonzalez-Meler et al. 2004). Almost all plants reproduce and respire, therefore it is important to know what factors could affect the rate of photosynthesis and respiration to better understand how plants function. Some research has shown that elevated CO2 concentrations may determine plant…

purposes of respiration by examining his predecessors’ various theories on the matter and proving which of these theories must hold true. He spends a lot of time disproving Erasistratus’s theories of respiration as a means to replenish arteries and appears to believe that Hippocrates’ ideas on respiration respiration for the purposes of both cooling and nourishment. Though not mentioned by name, Galen’s views on respiration appear to match up on key points with Aristotle’s views on respiration,…

Cellular respiration is a very interesting topic that we are currently learning about in our biology class. What makes this particular topic so remarkable are all of the different elements that work together for cellular respiration to occur in human beings and animals. In the video, “ATP & Respiration: Crash Course Biology #& 7.” (ATP & Respiration: Crash Course Biology #7. n.d.). The narrator does an excellent job of explaining the cellular respiration process in a very clear cut…

Photosynthesis and Cellular Respiration is just like a bee and flower. As a bee pollinates a flower, the flower gives the bee nectar. Photosynthesis gives Cellular Respiration sugar and oxygen and Cellular Respiration gives carbon dioxide and water to Photosynthesis. The making of food using the sun's energy is called Photosynthesis. Photosynthesis occurs in the organism called Chloroplast. There is a green pigment inside the Chloroplast called Chlorophyll which absorbs light from the sun. Then…
