Explanation:

For the first question: Diastolic pressure occurs during ventricular relaxation (diastole), when the heart fills with blood. Atrial contraction (A) and relaxation (C) are not related to diastolic pressure; ventricular contraction (B) is systolic pressure; heart rate (E) is separate from pressure phases.
For Question 24: Blood pressure is defined as the force of blood pushing against artery walls. Interstitial fluid (A, C) is not blood; ventricles (B) are heart chambers, not the target of blood pressure measurement.

Answer:

D. The relaxation of the ventricles
D. The force that blood exerts on the walls of the arteries
