The statement is true.
Renin-angiotensin system will be activated when there is a loss of blood volume (or decrease of blood pressure, such as in haemorrhage or dehydration. <span>Renin is secreted by kidneys directly into the circulation when the blood flow is reduced. Renin then stimulates conversion of angiotensinogen, released by the liver, to angiotensin I which will then be converted to angiotensin II by the angiotensin-converting enzyme (ACE) found in the lungs. Angiotensin II is a vasoconstrictor(increases the blood pressure) and also stimulates the secretion of the aldosterone from the adrenal cortex. Aldosterone increases the reabsorption of sodium and water into the blood and the excretion of potassium (to maintain electrolyte balance). This also increases blood pressure and retention of water.</span>

Paraphrasing is the act of rewording, revising, simplifying and expressing the text in your own words with additional clarity. Note that condensing the text to a shorter form should not be in your interests because that would be summarizing, not paraphrasing. Check this out:

Nonliving organisms and lifeless organisms are not the same thing. Inanimate organisms are not dead, they're nonliving. Being nonliving means not having a characteristic of life, it means that the object is inorganic. A valid example could be a rock. A rock has never had a characteristic of life. Being deceased means that life once inhabited the being and has left it. Just as a moose gains life from conception, it's deemed dead once life has left it. In science, nonliving organisms and lifeless organisms are not the same thing; one was gifted life and one was inanimate from the beginning.
