In biology, a population can be described as the number of organisms of a species which are living together in a habitat at a particular time. These organisms have the capability to interbreed and produce fertile offspring.

Explanation:
Answer:
The urinary system or the Renal systems regulates or takes out waste from the blood, maintain blood pressure, and controls the ion exchange process.
The parts of urinary system includes:
- Kidneys
- Ureters
- Bladder
- Urethera
Formation of urine :
When the blood passes through the kidney, it filters the blood. This is a 3 step process:
1) Glomerus filtration: This is the place where formation of urine starts. In glomerus, the water and solute from tiny capillaries and enter the capsule of the glomerus.
2) The tubular re-absorption: Most of the water and solute gets reabsorbed through this part
3) Tubular secretion: Extracellular fluid molecules get transferred into the nephron, these secretions get discarded out of the body containing mainly creatinine, urea, uric acid, K+ and H+ ions
NEPHRON :
The simplest unit of kidney and its the basic unit that filter the blood. One kidney has approximately 1. 5 million nephrons!
