Explain the role of each organ of the urinary system.
To review:
The role of each organ of the urinary system.
Introduction:
Body cells perform metabolic activities and produce waste products like urea, carbon dioxide, and uric acid. The waste products are eliminated from the body via respiratory system and urinary system.
Explanation of Solution
The urinary system is made up of the organs such as
1. Kidneys: Urinary system consists of two kidneys. The primary function of kidney is to filter out wastes from the blood and excrete waste products through urine. Kidney also functions in regulating blood composition, pH, volume, and pressure. Their main function is to maintain blood osmolarity and produce hormones, such as calcitriol and erythropoietin.
2. Ureter: It is the passage, through which urine from the kidney reaches to the urinary bladder for storage till elimination. There are two ureters.
3. Urinary bladder: It is the storage organ that stores urine before its expulsion into the ureters.
4. Urethra: Urethra is the organ, through which urine is excreted from the body.
Thus, urinary system is made up of two kidneys, one urinary bladder, two ureters, and one urethra. The overall function of urinary system is to get body rid of toxic waste products like urea and uric acid in the form of urine.
