• Receive oxygen, release carbon dioxide
• Lungs support the high Metabolic Rate
• Lungs have Alveoli (Gas Sacs)
• Humans have 300,000,000 Alveoli
• Have a diaphragm
• Moves air in and out

Dolphin

• Have a penis or uterus
• Some lay eggs

  skin

• Blood flows to Kidney
• Ureter drains kidney
• Kidney drains into urinary bladder
• Urine exits bladder through urethra
