ANATOMY

Detailed explanation-1: -Increased cardiac output increases the blood pumped from ventricles per minute and thereby increase the blood volume in major blood vessels. Increased blood volume causes an increase in blood pressure. Sympathetic nervous system stimulates constriction of blood vessels and thereby, increases the blood volume.

Detailed explanation-2: -Blood volume: increased blood volume increases blood pressure. An injection of 250 mL water causes blood pressure to rise by 10 mmHg within 60 min.

Detailed explanation-3: -How Blood Volume Affects Blood Pressure. Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end-diastolic pressure and volume.

Detailed explanation-4: -Having a normal blood volume is important because it allows your blood to reach all the tissues and organs in your body. However, a low blood volume can cause your blood pressure to drop. If you’re dehydrated, your blood volume and blood pressure can drop too low.

Detailed explanation-5: -Stress-related habits such as eating more, using tobacco or drinking alcohol can lead to further increases in blood pressure. Certain chronic conditions. Kidney disease, diabetes and sleep apnea are some of the conditions that can lead to high blood pressure.
