**Task 1**
=Lateral View= 1.

=Ventral View= 2.

3. **Glossary**
Dorsal-Pig's back Ventral-Pig's underside Anterior- Font of pig Posterior- Back of pig Pectoral- Chest Pelvic- Hip area Head-Pig's head Trunk-The pig's lower back Thorax-The middle section of the pig

Abdomen-Stomach muscles of the pig Medial-The middle plane of the pig Caudal- Tail Cranial- Head Umbilical Cord-This is the connecting cord from the embryo or fetus to the placenta Mammary Papillae-The nipples of the pig

Proximal- Where the legs attach Distal- Where something connects Lateral- Side view Left- When facing the pig, your positions are opposite; your right is the pig's left. Right- When facing the pig, your positions are opposite; your left is the pig's right.

**Task 2**
=Head View= 1.

=Female Pig= 2.

=Male Pig= 3.

=Umbilical Cord= 4.

=Legs= 5.

6.Glossary
Pinnae-Ear Eye-The eyeball of the pig Nictitating Membrane-The third eyelid Eyelids-Cover the pig's eye. Urogenital Opening-Where wast products and reproductive fluids are expelled Urogenital Papillae-Where pig's urine comes out Anus-Where the pig excretes waste Scrotal Sacs-Holds the pig's testes. Artery-Any of the muscular elastic tubes that carries blood away from the heart Veins-Carries blood to the heart Ankle-Connects the foot to the leg Knee- Connects thigh with the leg Elbow- The joint in the middle of the fore limbs Toe- Helps with balance

Questions
7. The veins take blood to the heart, and the arteries take blood away from the heart, to other parts of the pig's body. 8. Both sexes have a mammary papillae because this is where pig's expel liquid. 9. Our pig has 14 mammary papillae 10. Humans and pigs have similar forelegs and hind legs because we both contain wrists, and ankles. Pig's legs are made for waling on all four and human's are made for walking on our hind legs and using our fore legs to touch and grab things.

=Mouth Anatomy=

**Task 3**
=Mouth= 1.

2. **Glossary**
Epiglottis-This is elastic cartilage tissue covering the mucus membrane and is attached to the tongue Glottis- Vocal folds Gullet-Esophagus of the pig Nasopharnyx-Upper surface of the soft palate Soft Palate-soft tissue on the back of the roof of the mouth Hard Palate-The thin, bony plate on the roof of the mouth Nare-Nostril Tongue-Muscle on the floor of the mouth Taste Buds-Located on the upper part of the tongue that provides information about the taste of the foods being eaten Vestibule-A small space or cavity at the beginning of the throat Uvula-Made up of connective tissue made of a number of racemose glans and some muscular fibers

3. The epiglottis is a flap of skin located on top of the glottis and it covers it when the pig swallows. The glottis covers the lungs when eating, so food does not go down. The gullet is the opening to the esophagus and is located beneath the glottis and epiglottis. This is where food goes because the gullet leads to the stomach. These organs all begin the digestive system.

=3. Tongue and Taste Buds=

The tongue is the muscle on the floor of the mouth. The taste buds are located on the upper side of it, and they are used for providing information about the taste of what is being eaten.

4. The upper jaw of the pig contains the teeth. The teeth start erupting when they are in the womb and they are born with about eight.

=**Skinning the Pig**=

Task 5
1.



Questions
2. This skin is 1mm thick. 3. The cutaneous muscle attaches the skin to the body of pig, along with connective tissues. 4. The skin of the pig protects the muscles, exchanges gases through its pores, and protects it from bacterial infections.

=Muscles=



Joint- This is where two bones are attached for the purpose of motion of the body. It is formed of fibrous connective tissues and cartilage. Extensor- This muscle is for straightening or extending a part of the body. Flexor- This is used to flex or bend a part of the body. Origin- The end of the muscle attaching to the relatively fixed bone of its joint. Insertion- the point at which a muscle attaches to the skin, a bone, or another muscle. Belly- The front or underside of the pig. Tendon- A cord of fibrous tissue serving to connect muscle with a bone. Fascia-the soft tissue component of the connective tissue system and interpenetrates and surrounds muscles, bones, organs, nerves, blood. Vessels and other structures- Antagonistic Pairs- These consist of an extensor muscles, which opens the joint. Adductor- is a movement which draws a limb towards the median. Abductor- is a movement which draws a limb away from the median.

Questions
5. The fetal pig liver has five lobes: right lateral, right central, left central, left lateral, and caudate. 6. The liver produces bile and the gallbladder stores and releases it for digestion. 7. **Duodenum** is responsible for further processing the material form the stomach, **Jejunum** has a lining which is specialized in the absorption of carbohydrates and proteins, **Ileum** is responsible for absorption of fats. 8. The colon on a pig is reversed compared to ours because ours is on top of the small intestines in the shape of an upside down "u" a pigs is at the bottom of it's small intestines.

=Respiratory System=



=Vocal Cords=

=Respiratory Chart=

Questions

4. The right lung has four lobes the apical, cardiac, diaphramatic, and the intermediate lobe. The left lungs has three lobes apical, cardiac, and diaphragmatic lobe. 5. We saw only two visible vocal cords. The other group at our table also saw two.

Questions
6. The left ventricle has the greater muscle mass 7. The pulmonary artery is connected to the right ventricle; the lower right chamber. 8. The aorta is connected to the left ventricle. 9.

6. They are studied together because the share many organs.

7. The main purpose of the excretory system is to maintane the water level in the pigs body.

8. The main purpose of the reproductive system is to keep the species alive.

9. The iquid waste goes from the stomach into the kidneys through the ureters, then down the urethra and out of the body.

10. The eggs are stored in the ovaries then they travel up through the fallopian tubes. Then down through the uterus and cerivx. Lastly the eggs go out the vagina.
