Study Notes
Excretion in Animals
- Excretion is the removal of waste products from the body.
- Waste products are generated during cellular functions and can be toxic.
- The excretory system removes these waste products.
Human Excretory System
- The human excretory system is responsible for filtering waste products from the blood.
- It consists of the kidneys, ureters, urinary bladder, and urethra.
Structure and Function
- Kidneys: These are the main organs of excretion. They filter waste from the blood and produce urine.
- Ureters: These tubes transport urine from the kidneys to the urinary bladder.
- Urinary bladder: This organ stores urine before it is expelled from the body.
- Urethra: This tube carries urine from the bladder to the outside of the body.
- Urinary Opening: This is the opening through which urine is expelled from the body.
Additional details
- An adult human produces roughly 1-1.8 liters of urine daily.
- Urine is primarily composed of water, urea, and other waste products.
- Perspiration (sweat) is another way waste is eliminated from the body.
- The excretory system contributes to maintaining homeostasis within the body.
- Damage or disruption to the excretory system can lead to health problems.
