LAB WORK REPORT

Title: Chicken Dissection Lab.

Introduction: Bird anatomy shows many unique adaptations, mostly helping flight. Birds have a light skeletal system and light but powerful muscles which, along with circulatory and respiratory systems capable of very high metabolism and oxygen supply, allow the bird to fly. There is a relationship between beak and specially adapted digestive system.

Purpose: to Identify the major internal organs of a bird. To compare and contrast human and bird internal organs, structures, and systems.

Hypothesis: Even though humans and birds do not look the same, we share almost similar organs and body parts. Hmmm.

Equipment:

Procedure:

1. Identify external anatomical features of a bird.

comb

beak (no salivary glands - no digestion in a mouth)

ear lobe (colour!)

scale on the legs

2. Identify a few major internal organs of a bird.

esophagus

crop (a pouch in a bird's gullet where food is stored or prepared for digestion)

keel bone

liver

gallbladder

heart

gizzard

intestines

spleen

small intestine

caecum

cloaca

follicle

uterus

lungs

air sacs

3. Compare and contrast human and bird internal organs, structures, and systems.

Result:

1. Draw the picture of the bird with internal and external features.
2. Write usual result like in a Sample Lab Work.

Conclusion:

Write usual Conclusion like in a Sample Lab Work.
