Abstract

 

In this lab, our group examined the internal and external structures of a fetal pig. Considering that the fetal pig is an vertebrate it has a very close resemblance of how the human body is structured and functions.While examining the fetal pig we are searching for its main organs such as, the heart, kidneys, liver, gallbladder,small and large intestines, stomach, spleen, diaphragm, lungs, and pancrease. We also investigated some of the bodies systems such as the respiratory, reproductive, cardiovascular, and digestive.

 

 

Circulatory System:  

The circulatory system contains three significant components which are the heart, blood vessels and of course blood. The heart plays the most important role in the circulatory system for it is responsible for pumping blood through the body which helps balance the homeostasis of the body. The blood vessels are also important for they are responsible for carrying the blood throughout the body. Last, blood is also a significant factor in the circulatory system because it is blood that act as a filter for oxygen that is needed to keep the body alive

 

 

 

Digestive System:

 

The digestive system is where it all begins as it relates to energy conversion. We consume food and convert it into energy that we can use. The digestive system begins in the mouth and starts with the enzyme within saliva. The saliva basically softens up the food so that chewing and later digestion become easy. There are three main components that make up the digestive system which is the mouth, esophagus, stomach and the small and large intestines.

 

 

Reproductive System:

 

The reproductive system is one of the most amazing systems found in organisms. For some creatures, they have both sets of genitalia while others can switch genders if necessary. There are only two types of reproductive systems among vertebrate which are the male genitalia and the female genitalia. The male genitalia or testes are male reproductive organs where sperm and testosterone is produced. The male uses his testes and production of sperm to fertilize the egg of a female. The female genitalia or the vagina produces eggs for fertilization. When a female’s egg is fertilized it attaches to the walls of the uterus of the female where it will begin to grow.

 

 

Respiratory System:

 

  The respiratory system is an extremely important part of system of vertebrates. The respiratory system is important for providing oxygen to the cells of the body and removing carbon dioxide in the process. When oxygen is breathed into the lungs the lungs are filled with air causing the diaphragm to contract which allows air to be sucked into the lung cavities.
