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 . ∞. Plants and animals are linked for survival through the carbon dioxide-oxygen cycle.. Photosynthesis. To undergo photosynthesis, plants need:. sunlight. water. carbon dioxide. Carbon Dioxide. Photosynthesis. 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.. 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?.

Most of the water vapour condensed and formed oceans. LARYNX. NOSE. MOUTH. PHARYNX. TRACHEA. BRONCHIOLES. DIAPHRAGM. BRONCHI. ALVEOLI. PLEURA. Write the word that best describes the definitions below:.  . The gas we breathe in. .  . The little branches in our lungs.  . 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. Remember the activity we did earlier this week?. Any comments? Or reflections?. What is the fire triangle? . What is in the air that fire needs to burn? . Oxygen!!!. Living things also need oxygen, we love oxygen. . 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 Abdullah A. .
