- Ischemic hypoxia is the result of: inability of the cells to use oxygen compromised oxygen transport due to blockage or constriction of blood vessels substitution of oxygen by another substance, e.g. carbon monoxide compromised ability of oxygen tansport due to low hemoglobin low environmental oxygenPoor blood circulation causes hypoxia.a. ischemicb. histotoxicc. hemolyticd. anemice. hypoxemicWhich one is NOT the cause of anemic hypoxia? . decreasing the number of erythrocytes. . carbon monoxide . hemorrhage . decreasing the number of functional hemoglobin . high altitude
- Which of the following applies to Sickle Cell Anemia? Choose all that apply. Group of answer choices It is a genetic disease. It is transmitted by mosquitoes. It is due to a mutation in the hemoglobin gene. It is harmful to people because it causes the overproduction of CO2.In carbon monoxide (CO) poisoning, CO binds to the heme of hemoglobin much tighter than oxygen (O2). What effect will this have on the ability of the tissues to get oxygen? Group of answer choices There will be no effect. CO will deliver oxygen to the tissues. Hemoglobin will bind more O2 and deliver more oxygen to the tissues. More hemoglobin will be produced to deliver oxygen to the tissues. Hemoglobin will bind less O2 and deliver less oxygen to the tissues.Create a concept map using these terms. 120 days Formed elements Bi-concave disc Hematocrit Mitochondria Rouleaux Anaerobic metabolism Capillaries ЕРО Nuclei Androgens Нуроxia Erythropoiesis Hemoglobin Oxyldeoxyhemoglobin Mechanical stress Hemolysis Macrophages Alpha and beta chains Red bone marrow Hematuria Liver Biliverdin Spleen Bilirubin Kidneys Quaternary Structure
