Question

Effect of increased blood volume and sympathetic and parasympathetic nervous system

Answer 1

Answer:

#⃣✌♥️The sympathetic and parasympathetic branches of the autonomic nervous system have opposing effects on blood pressure. ... Conversely, parasympathetic activation leads to decreased cardiac output via decrease in heart rate, resulting in a tendency to lower blood pressure.#⃣✌♥️

Answer 2

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.
