  1. EXCRETORY SYSTEM Ashley Khamo Mary Ann Jariq Alexia Lumayag

  2. Importance of excretory& excretory system • The importance of excretion is that the skin acts as an organ • Includes a pair of bean-shaped kidneys • Kidneys are located in the abdominal cavity, which you need • Excretory system is also called the urinary system • Excretory system gets rid of wastes 2

  3. Examples of cells • Four distinctive cells types make up the excretory system • One pore cell • One duct cell • One canal cell • Fuse paired of gland cells 3

  4. Examples of tissue & organs in our bodies • Excretory system’s main tissue is the liver • Liver – large organ located to the right of your stomach • The organs in the excretory system are the: • Liver • Lungs • Skin • Kidney • Bladder 4

  5. System name & relation to our bodies • Another name for excretory system is urinary system • Urinary bladder gets rid of fluid from body (remove wastes) • Excretory system is a passive biological system • Removes excess, unnecessary or dangerous materials from an organism 5

  6. Epidermis • The thin protective outer layer of the skin • Composed of satisfied epithelial tissue • Covering an organism • Also called cuticle 6

  7. Role of skin, lungs kidneys, and liver • Lungs • Cellular respiration that occurs in every living cell in your body • Liver • Large organ • Skin • Sweat comes out of pores in your skin • Kidneys • Two tubes called ureters • Urinary bladder • Urethra 7

  8. Structure of kidneys and associated structures • Ureters connects to the kidney and bladder • Transportation system for urine • Bladder is where urine is stored before its released from the body • Urethra is final stage of the urinary tract • Excretes urine out of the body, from the bladder 8

  9. Urine transportation and urea formation • Urine leaves the body through the urethra • Urine from the collecting ducts flows through the real pelvis and into a table called a ureter • Urea is formed in the liver 9

  10. Nephron • Urine is made in structures called nephrons • They’re functional units in the kidneys • The substances removed from the blood by the kidneys are toxins, urea, water and mineral salts • That forms a amber-colored liquid called urine 10

  11. Circularity system in kidneys • Circularity system supplies the kidneys with blood • Through the renal artery • Also helps urine go to the bladder 11

  12. Peristalsis • Peristalsis is the series of rhythmic muscular contractions • move food through the digestive tract 12

  13. Bile and where it’s produced • Bile is greenish or yellowish substance • Secreted by the liver used for breaking down fats, ethanol, and acidic wastes • Bile is released through bile ducts in the liver • A digestive chemical is produced in the liver • Its stored in the gall bladder • Secreted in the small intestine 13

  14. Duodenum and its function • Duodenum is the upper portion of the small intestine • Its main function is to receive the partially digested food from the stomach • Completes the process of digestion 14

  15. Disorder in kidney failure • Kidney are primary excretory organs • Prostate cancer results in kidney failure • Prostate cancer can block the urethra • That prevents the bladder from emptying 15

  16. Additional information • The primary function of the excretory system: • Get rid of wastes • Eliminates useless by-products excreted from cells • Eradicates harmful chemical builds up • Maintains a steady, balanced chemical concentration 16
