*Summary of Excretion in Humans and Plants*

*Introduction*
Excretion is a vital life process that involves the removal of waste products from the body. This section focuses on the excretory system in humans and the mechanisms of excretion in plants.

*Excretion in Humans*
- *Definition* : Excretion refers to the process of eliminating waste products from the body that are harmful and not useful.
- *Need for Excretory System* :
1. *Removal of Toxic Waste* : The body undergoes various biochemical reactions, such as aerobic respiration, which produce toxic waste products like nitrogen compounds (e.g., urea and uric acid) that must be eliminated.
2. *Regulation of Water Balance* : The excretory system helps maintain the balance of water in the body. Increased water intake leads to more urine production, while reduced intake results in less urine.

*Components of the Excretory System*
- * Kidneys* : The primary organs responsible for filtering blood and producing urine. Humans have two kidneys, which are bean-shaped and located in the abdominal cavity.
- *Ureters* : Tubes that carry urine from the kidneys to the urinary bladder.
- *Urinary Bladder* : A muscular sac that stores urine until it is expelled from the body.
- *Urethra* : The tube through which urine is discharged from the body.

*Functioning of the Excretory System*
1. **Blood Filtration**: Blood enters the kidneys through the renal arteries, where it is filtered in structures called nephrons.
2. *Nephrons* : The functional units of the kidneys, consisting of:
- *Bowman's Capsule* : A cup-like structure that collects filtrate from the blood.
- *Glomerulus* : A network of capillaries where filtration occurs.
- *Tubule* : A tube where reabsorption of useful substances (like glucose and amino acids) occurs, while waste products remain in the filtrate.
3. **Urine Formation* : The remaining waste products, including urea and excess salts, are collected as urine and stored in the urinary bladder until excretion.

*Excretion in Plants*
- *Gas Exchange* : Plants excrete gaseous waste products (like oxygen and carbon dioxide) through diffusion via stomata and lenticels.
- *Water Regulation* : Excess water is removed through transpiration, a process where water vapor is released from the leaves.
- *Storage of Waste Products* : Some waste products may be stored in leaves or stems until they can be eliminated.
- *Secretion of Resins and Gums* : Certain plants secrete substances like rubber, which are considered waste products.
