Identify the white blood cell in the image below. Fill in the blank

A. Bone marrow and the thymus: those are organs/tissues involved in blood cell production/maturation, not the formed elements themselves.
B. Blood and lymph: these are fluid compartments, not the formed cellular elements suspended in blood.
C. Blood cells and platelets: “formed elements” refers to erythrocytes, leukocytes, and platelets (the cellular/fragment components of blood).
D. Sodium and potassium: those are electrolytes/ions in plasma, not formed cellular elements.

A. Decreased CO₂ and hydrogen ion concentrations and increased oxygen concentration stimulate her chemoreceptors, triggering inspiration. - Chemoreceptors respond to increased CO₂/decreased O₂.
B. The inflation reflex would not allow her to keep her lungs full of air for a prolonged period. The reflex would trigger inspiration. -The Hering–Breuer reflex prevents overinflation, not relevant here.
C. Increased CO₂ and hydrogen ion concentrations and decreased oxygen concentration stimulate her chemoreceptors, triggering inspiration. -Rising CO₂ strongly stimulates medullary chemoreceptors → involuntary breathing resumes.
D. The diaphragm will begin to fatigue and will not be able to hold its contracted position for more than a short period of time. -Breathing resumes due to chemoreceptor drive before muscle fatigue sets in.
