Urinary System Part 1
What are two tremendous roles of the liver?
How many kidneys do we have?
Two
The kidneys filter about how many liters of blood every day?
120 – 140 liters.
What is the urea?
What is a muscular, balloon-like organ that stores urine temporarily.
Bladder.
What are some of the hemostatic stuff that the kidneys do?
Regulating water volume, ion salt concentration, and pH levels and influencing red blood cell production and blood pressure.
The kidney holds over what percent of your total blood volume?
20%
When all of the stuff that get squeezed out of the blood into the glomerulus is called?
Filtrate.
The remaining filtrate of urine is located where?
The collecting ducts
What is a tube that carries urine from the bladder out of the body during urination?
Urethra.
What is the main purpose of the kidneys?
Oxygenated blood enters the kidneys through the?
Large renal arteries.
What creates tons of little capillary groups?
Renal arteries.
What refers to the rate of change of a function, often visualized as the slope of a line or the direction of steepest ascent on a surface
A gradient.
What are two bean-shaped organs, located just below the rib cage on either side of the spine, are the main filtering units?
Kidneys.
How does kidneys filter toxic leftovers from your blood?
What are the nephrons?
Microscopic filtering units.
What usually end sup in the tubules?
Ion, glucose and water.
What is the duct by which urine passes from the kidney to the bladder?
Ureter.
What is a crucial part of the kidney's nephron system, playing a key role in regulating water and electrolyte balance and maintaining the body's overall homeostasis. It receives filtrate from multiple nephrons and is the final site where the urine's composition is adjusted before it exits the kidney
The collecting duct.
What are the three layers of the kidney?
Renal Cortex, Renal Medulla, Renal Pelvis
What are the three steps of the urination process
Filtration, reabsorption, secretion
What are the three major parts of the renal tubule?
How does urine travel through the urinary system?
What is the primary task of the loop?
To drive re-absorption water by creating a salt concentration gradient in the tissue of medulla.
