Part 1:Thoracic Cavity
a) What organs are found in the thoracic cavity?
b) Compare the size of the wall of a ventricle with that of an atrium.
c) Why does the left ventricle contain more muscle than the right ventricle?
d) Why do the lungs feel spongy?
e) Describe what happens when you place your index finger on the trachea and push downward
f)What function do the cartilaginous rings of the trachea serve?

a) What organs are found in the thoracic cavity?
The organs found in the thoracic cavity are the lungs and the heart.

b) Compare the size of the wall of a ventricle with that of an atrium.
The size of the wall of a ventricle is thicker than an atrium, since the ventricles have to pump blood to different parts of the body versus the atrium only has to pump to another chamber of the heart.

c) Why does the left ventricle contain more muscle than the right ventricle?
The left ventricle contains more muscle than the right ventricle due to the fact that it has to pump blood throughout the body; versus just the lungs like the right ventricle.

d) Why do the lungs feel spongy?
The lungs feel spongy because of all the tissues that create them and allow them to expand.

e) Describe what happens when you place your index finger on the trachea and push downward
When we placed a finger over the trachea and pushed down it was slightly resistant to the movement and when pushing down it felt like an elastic band; hesitant but then springs back.

f) What function do the cartilaginous rings of the trachea serve?
The cartilaginous rings support and protect the trachea, however they still allow the esophagus to expand.

g) Describe the shape and colour of the kidneys?
The kidneys are an ovular shape and are a soft but dull pink and brown-gray colour that look like kidney beans.

2. How is the abdominal cavity separated from the thoracic cavity?
The abdominal cavity is separated from the thoracic cavity by the diaphragm. It is a dome-shaped sheet of muscle and tendon that also serve in respiration and the breathing process.
3. Indicate why the male reproductive system is often referred to as the urogenital system while the female’s is not.
The term urogenital refers to something that has both urinary and genital organs. The male reproductive system is often referred to as the urogenital system because the urinary and reproductive systems merge. In males the urethra carries both urine and seminal fluid, therefore crossing the two systems and getting called the urogenital system. The female reproductive system is not referred to as the urogenital system because the two systems do not meet.

These arrows point to the ureters that lead from the kidneys into the urinary bladder. They are harder to see because we didn't clear away all the excess fluid and tissues before taking the picture.

We were able to confirm that our pig was a girl when we found the evidence. We assumed that it was a girl by signs on the exterior but weren't positive until we found these!
