Excretory System

The excretory system is responsible for removing waste and excess materials from the body. It includes several organs and structures that work together to maintain a healthy balance of fluids and chemicals within the body.

Organs of the Excretory System

1. Kidneys: The kidneys filter waste products and excess substances from the blood to produce urine.
2. Ureters: These are tubes that carry urine from the kidneys to the bladder.
3. Bladder: The bladder stores urine until it is released from the body.
4. Urethra: This is the tube through which urine is expelled from the body.

Functions of the Excretory System

The excretory system performs several important functions, including:

• Regulating the balance of water and electrolytes in the body
• Removing waste products such as urea and ammonia from the blood
• Regulating blood pressure through the production of hormones such as renin
