Unformatted text preview: ovalently bound to hemoglobin in 100 ml of arterial blood Hematocrit ↑ Hct ↑ O2 capacity Changes in Affinity of Hemoglobin For Oxygen Changes Factors that cause right shift: ↑Temperature ↓ pH (Bohr effect) ↑CO2 (carbamino effect) In the transition from rest to exercise, temperature and CO2 production increase, and pH decreases. All of these changes facilitate delivery of O2 from blood into tissues.
