What is the definition of renal circulation?
Renal circulation is when the blood is cleaned and filtered in the kidneys, and then blood goes back to the heart.
Renal circulation is the circulation of blood between the heart and the kidney to effectively remove and filter waste materials from the blood. Excess fat, salt, extra water and other waste materials in the blood are being excreted because of the kidney.
The blood goes down to the kidney through the abdominal aorta. Then the blood goes into the kidneys. Inside the kidney are renal pyramids made up of nephrons and collecting ducts. The nephrons filter out the waste materials and will be collected by the collecting ducts. After this, the urine travels into the ureter then to the urinary bladder. The urine then goes out of the body through the urethra.
Fun fact: The color of urine determines how much water you take each day. Colorless urine means you drink enough water and that the urine is not concentrated. Yellow and orange urine means you need to drink a lot more water and the concentration is high. (Sometimes, chemicals from vitamins turn urine into yellow or orange.) If it is any other color, go have a check-up
