- THORAX; 3 pairs of legs (6 legs in total)
- ABDOMEN ]]> 2019-11-18 01:01:56 UTC https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471756 HEAD axelesqueda https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471757 - Two sets of eyes
 - Ocelli(simple eyes): are photoreceptors
 - Compound eyes: Sees shapes, colors & different directions
 MOUTH
- 5 mouthparts: 
Labrum: Upper Lip
Hypopharynx: An internal structure; a tongue-like structure 
Maxilla: A way for them to grab their food; also a way to taste or smell
Mandible: A way for them to grip their food

Prothorax (the top is called Pronutum)
Mesothorax; the forewing is attached here
Metathorax; Hindwing is attached here
LEGS
All the pairs of legs are attached to the thorax, each pair to each segment of thorax
Legs can be heavily modified
Segments of the legs:
Proximal -> Distal 
- Coxa
- Trochanter
- Femur 
- Tibia 
- Tarsus
- Claws ]]> 2019-11-18 01:01:56 UTC https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471758 ABDOMEN axelesqueda https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471759 11 or fewer segments ]]> 2019-11-18 01:01:56 UTC https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471759 INSECT ANATOMY axelesqueda https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471760 INTERNAL STRUCTURE]]> 2019-11-18 01:01:56 UTC https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471760 DIGESTIVE SYSTEM axelesqueda https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471761 Insects have a complete Digestive System (mouth -> anus)
3 major regions:
Foregut 
- Lined with chitin (makes up their exoskeleton)
- Includes a crop & gizzard
Midgut
- No Kidneys but they have Malpighian tubules to remove metabolic waste 
- Enzymatic Digestion 
- Ceca secretes these enzymes
Hindgut 
- Lined with chitin (makes up their exoskeleton)
- Waste excreted here 
Rectal glands reabsorb chloride, sodium, and water ]]> 2019-11-18 01:01:56 UTC https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471761 Circulatory System axelesqueda https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471762 Open System
Blood from the heart leaves via dorsal aorta & is sent to open spaces in the hemocoel 
Pulsatory Organs & body movements help the hemolymph into wings or legs
Hemolymph has little role in 02 transport in most insects but hemoglobin occurs in the hemolymph of some species; particularly aquatic species & does function to transport 02  ]]> 2019-11-18 01:01:56 UTC https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471762 Respiratory System axelesqueda https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471763 No lungs
Takes in O2 and exhales CO2
Has a tracheal system: A network of tubes that branch everywhere in the body
Spiracles help with gas exchange
- openings on the sides of the body
- normally 2 pairs on the thorax; 7-8 on abdomen
- A filtering device to help prevent H2O, parasites, and dust from entering the tracheal system 
Tracheae branch out into fluid-filled tracheoles ]]> 2019-11-18 01:01:56 UTC https://padlet.com/axelesqueda/cwgf7j5rxdnd/wish/412471763
