I did a pig dissection , but i am not to sure about these questions, any help would be great !
1. The lungs of a fetal pig serve as a protection for what important body organ
2. The respiratory system is located on the ventral side of the pigs body, what 3 ways is the tract physically protected
3.) What body part is the diaphragm immediately superior to, how would this body part be affected during an inhalation
Sure, I'd be happy to help you with these questions!
1. The lungs of a fetal pig serve as protection for the heart. The lungs surround the heart and provide a cushioning effect, helping to protect it from external impacts.
To find the answer to this question, you can refer to your knowledge of the anatomy of a fetal pig or review your dissection notes. Alternatively, you can use resources like textbooks, online anatomy references, or educational websites that provide information on fetal pig dissection.
2. The respiratory system of a pig is located on the ventral (front) side of its body. There are three ways in which the respiratory tract is physically protected in a pig:
a) Ribs: The ribs form a protective cage around the thoracic cavity, which houses the respiratory organs such as the lungs and the trachea.
b) Sternum: The sternum, or breastbone, provides additional support and protection to the front part of the respiratory system.
c) Rib Muscles: The intercostal muscles between the ribs contract and expand during breathing, providing additional support and protection for the respiratory organs.
To answer this question, you can use your observations from the dissection, along with your understanding of the skeletal and muscular structures of the pig's body. You can also refer to diagrams or illustrations of the pig's anatomy, or consult educational resources that provide information on pig dissection.
3. The diaphragm is immediately superior to the abdominal organs. During an inhalation, the diaphragm contracts and moves downwards, increasing the volume of the thoracic cavity. This expansion leads to a decrease in pressure within the thoracic cavity, causing air to rush into the lungs.
To determine the answer to this question, you can refer to your knowledge of the anatomy and physiology of the respiratory system. You can also use resources like textbooks, anatomy guides, or online references that explain the role and position of the diaphragm during respiration.
Remember, it's always a good idea to cross-reference multiple sources to ensure accurate and comprehensive understanding of the subject matter.
