Answer: True
Explanation:
Kidneys are defined as a pair of bean-shaped organ present in the abdominal cavity of mammals, reptiles, and birds responsible for excretion of urine.
Renin is a peptide hormone which is secreted by the kidneys from granular cells that are present in the juxtaglomerular apparatus. The secretion of renin stimulation is based on decrease in sodium chloride in the juxtaglomerular apparatus by the macula densa, fall in arterial blood pressure in the arterial vessels by baroreceptors and sympathetic nervous system activity is through beta 1 adrenergic receptors.
Hence, the given statement is true.
