  5. Warm up quiz (5 min) • What are the 2 Jobs of the Respiratory System? • #1 - MOVES OXYGENFROM THE OUTSIDE ENVIRONMENT INTO THE BODY • #2 - REMOVES CARBON DIOXIDE AND WATER FROM THE BODY • Bronchi keep dividing until they _____________________ (ends) in air sacs called alveoli • Terminates

  6. The ExecretorySystem Mr. Mah Living Environment Lecture 6

  7. Aim: How does the excretory system help us maintain homeostasis?

  8. The Excretory System

  9. Functions of the Excretory System • maintain homeostasis • Remove wastes through excretion (urination).

  10. Homeostasis • Regulates the chemical composition (what chemicals and how much of each chemical) of body fluids by removing wastes and keeping the right amounts of water, salts, and nutrients. • The average adult produces 1.5 Liters of urine a day.

  11. Excretion • The skin excretes excess water and salts in the form of sweat. • The lungs excrete carbon dioxide. • The kidneys also play a major role in excretion.

  12. The Kidneys • remove waste products from the blood. • maintains blood pH. • regulate the water content of the blood and, therefore, blood volume.

  13. Blood Flow • Blood enters the kidney through the renal artery. • The kidney removes urea, excess water, and other waste products through filtration and passes them to the ureter. • The clean, filtered blood leaves the kidney through the renal vein and returns to the body.

  14. Kidney Structure  • A kidney has two distinct regions: • The inner part is called the renal medulla. • The outer part is called the renal cortex.

  15. Ureter • A tube, called the ureter, leaves each kidney, carrying urine to the urinary bladder. • There are two tubes, one from each kidney.

  16. Bladder • The urinary bladder is a saclike organ where urine is stored before being excreted. • A full bladder holds about 500mL of urine

  17. Urethra • The tube that leads from the bladder to the outside of the body. • The urethra is of different lengths in each sex. • Males – about 8 inches • Females – about 1.5 inches

  18. Kidney Disorders • Humans have two kidneys, but can survive with only one. • If both kidneys are damaged by disease or injury, there are two options: • a kidney transplant • kidney dialysis

  19. Excretory System Problems • Kidney stones – crystallized mineral salts and uric acid saltsin the urine. Stones block flow of urine and cause excruciating pain. • Kidney failure - can be caused by long-term diabetes, infections, physical injuries, chemical poisoning. Causes toxic materials to build up to lethal levels.
