PPT-Oxygen and Carbon dioxide Transport

Dr Laila Al Dokhi Objectives Understand the forms of oxygen transport in the blood the importance of each Differentiate between O2 capacity O2 content and O2 saturation Describe . When carbon dioxide d_______ in water it forms carbonic acid. The more c______ dioxide the more a_______ the solution becomes . ie. . The pH d_________!. If distilled water (pH 7.0) is exposed to air the carbon dioxide from the air will form dilute carbonic acid (pH 5.5-6.0). Why Study Photosynthesis?. *All food webs start with photosynthesis!*. Photosynthesis is arguably the most important biological process on earth because of two key chemical reactions. Liberating oxygen:. HCS 1070 SLO: 1.8-1.9. External Gas Exchange. The movement of gases between the alveoli and the capillary blood in the lungs.. Gas must move through both the alveolar wall and the capillary wall which are both very thin.. Bromothymol blue. Bromothymol blue (BTB) is a pH indicator. It is normally blue but turns yellow when the pH lowers. Carbon dioxide has a pH of 5.7. When carbon dioxide is present the color will change from blue to yellow. It can take many forms. Occurs when there is damage to the heart or arteries. Usually caused by plaque buildup. Atherosclerosis. is a form of cardiovascular disease. It is when . plaque. builds up on the inside walls of the . What is the atmosphere?. Definition: The envelope of gases surrounding planet Earth.. Why do we need the atmosphere?. The atmosphere provides protection for the planet from objects in space and contains gasses that help sustain life.. Topic 1. Key Points. C1.1 The early atmosphere. When the Earth was young, it was very hot and there were lots of volcanoes. The gases that escaped from these formed the Earth’s atmosphere.. This early atmosphere contained a large amount of carbon dioxide, along with some ammonia, methane, nitrogen and water vapour. There was no oxygen.. Lab Methods Day. June 25, 2013. Taylor . Myers. 2. Carbon Monoxide Concentration. % of CO, by volume, in the air. Digital readout. Analog output 0/2/4 to 20 mA. Carbon Dioxide Concentration. % of . CO2, . All . living things on Earth . contain carbon. But, what is carbon?. Why is it important?. Carbon is found all over the Earth. . . It is an element. It is in the air, in the ocean, in the Earth’s crust. Hydrogencarbonate Indicator. Increasing CO. 2. in indicator. Decreasing CO. 2. . in indicator. Atmospheric CO. 2. level. Hydrogencarbonate indicator is used to measure carbon dioxide levels in aquatic systems.. H6.1 Define partial pressure. Dalton’s Law of partial pressure states that the total pressure exerted by a mixture of gasses is the sum of the pressures exerted independently by each gas in a mixture. In aerobic respiration one molecule of oxygen is con-sumed for each molecule of carbon dioxide produced In the absence of oxygen ie anaerobic respiration carbon dioxide is produced without the concom Intro:. .
