Study Notes
Kidney Function
- Filtration of blood mainly takes place in the kidney.
Waste Product
- The waste product excreted by the kidneys is urea.
Nephrons
- Nephrons are the functional units of the kidney, responsible for filtration.
Ureters
- Ureters are tubes that transport urine from the kidneys to the bladder.
Glomerulus
- The anatomical structure that encases the upper end of the nephron and is involved in filtration is the glomerulus.
Excretory System
- The primary function of the excretory system is to remove waste and excess substances from the body.
Liver Function
- The main activity of the liver in relation to the excretory system is to break down and remove toxins and waste products.
Sweat Glands
- The organ that excretes excess water, salts, and a small amount of urea in sweat is the sweat glands.
Lungs
- The organ that transports carbon dioxide, a waste product of cellular respiration, from the body cells to be excreted is the lungs.
Homeostasis
- A function of the excretory system that helps maintain homeostasis is the removal of waste and excess substances, which helps regulate various bodily functions.
Test your knowledge about the functions of the excretory system in maintaining homeostasis. Learn about how the excretory system removes toxins, regulates fluid and salt levels, and maintains blood pH for overall balance in the body.
