Shark Anatomy
H.S. Bio 2012
External Anatomy – (form = function)
• Shape = fusiform – • Olfactory= extremely sensitive• Spiracles- efficient respiration
Shape – form = functionwhere does the shark fit?
Olfactory System of Shark
• Not connected to mouth or respiration• Step 1- water in -incurrent appeture• Step 2- olfactory lamellae-series of folds• Step 3- info to olfactory bulb• Step 4 -info to olfactory lobe on front of brain• Step 5- water out –excurrent appeture

Respiratory System
Passive Transport in the Gills
Basic Circulatory System
Shark Heart
Digestive System
Human Digestive System
Urogenital System
• Excretory – Kidneys (osmosis revisited)• Sharks live in salt water• shark blood = 2.4 % urea compared to .01 to .03 in other vertebrates
Urogenital System /female reproductive
Integumentary System
• Placoid Scales
Types of Scales
Form = Function
