Final answer:
When there is hyper volemia, blood pressure, heart rate, and blood volume go up.
Step-by-step explanation:
When there is hyper volemia, meaning an increase in blood volume, all of the following numbers go up: blood pressure, heart rate, and blood volume. These increases are due to various factors such as sympathetic stimulation, release of catecholamines (epinephrine and norepinephrine), thyroid hormones, and increased calcium ion levels. These factors contribute to an increase in cardiac output, which in turn elevates blood pressure and promotes blood flow.
