Place a single word into each sentence to make it correct saturation The relationship between hemoglobin and Po2 is shown by an oxyhemoglobin dissociation curve. rises lowers At low Po2, the curve slowly load When the curve rises there is a rapid increase in oxygen loading. deficiency When the first heme group binds a molecule of oxygen, changes conformation to accept a second carbon dioxide Oxygen. Eventually at high Po2 levels, the hemoglobin approaches 100 % saturation and can not hemoglobin more oxygen.

During maximal aerobic exercise, exercise-induced arterial hypoxemia may result in elite endurance athletes due to which of the following? reduced venous return leads to decreased pulmonary capillary flow rate transit time through the pulmonary capillaries is much shorter oxygen diffusion capacity is no longer calculated using capillary mean PO2 lower venous O2 content increases the PO2 gradient
Sometimes Don prefers to dive simply by holding his breath. Based on the following oxygen saturation curve, explain why hyperventilating before a dive where you hold your breath will have little effect on the oxygen content of your body, given that the Pog of the lung capillaries is 100 mmHg during normal respiration at sea level.

Draw three separate oxygen-hemoglobin dissociation curves and then use arrows to show the change in oxygen saturation of most hemoglobins when: 1. deoxygenated blood enters the capillaries in the lungs. 2. oxygenated blood enters the capillaries in muscle tissue at rest. 3. oxygenated blood enters the capillaries in muscle tissue during vigorous exercise.
This lung disease causes "hypercompliance", increase in the partial pressure of carbon dioxide -- that leads to a barrel chest. FEV1/FVC is less than or equal to 70% in adults. What is this condition that would need a lung transplant? pulmonary fibrosis atelactasis AAT-deficiency Lou Gehrig's disease What condition can change an individual's skeletomuscular anatomy, causes decreased FVC With Proportional FEV1/FVC Ratio, and also decreases compliance of the chest wall? pulmonary fibrosis atelactasis AAT-deficiency Lou Gehrig's disease 3. This is a chronic lung disease that causes progressively worsening dyspnea. People with the condition may also experience a dry and persistent cough, progressive fatigue, or unexplained weight loss. Lung tissue show sign of connective tissue replacement of normal parenchymal tissue to the extent that it goes unchecked, leading to considerable tissue remodeling. It also causes…
Which of these factors in active tissue does not lead to greater release of O₂ from hemoglobin? elevated temperature O increased acidity O All of the other choices lead to increased release of oxygen O elevated carbon dioxide In anemia, the blood has low levels of hemoglobin and carries less oxygen (this is TRUE). Question: Does anemic blood have reduced PO2 compared with the PO2 of blood with normal hemoglobin levels? O Yes O No

pulmonary oxygenated systemic deoxygenated left right The circulatory system is divided into two circuits. The circuit transports blood through the lungs and returns the blood to the side of the heart. The circuit transports blood through the body, returning the blood to the side of the heart.
When a person develops a fever, which of the following statements hemoglobin saturation are correct? - Modify the structure of hemoglobin and decrease its affernity for O2 - Can shift the O2-hemoglobin dissociation curve to the right - Decrease O2 unloading occurs in the tissue - Modify the structure of hemoglobin and increase its affernity for O2 - Can shift the O2 hemoglobin dissociation curve to the left - Enhance O2 unloading occurs in the tissue
