Introduction In this procedure, the external and internal structures of a sheep’s heart was examined and identified by dissection. The heart is a muscle that pumps oxygenated blood and nutrients throughout the body. A sheep’s heart has four chambers like most mammals. Two of those chambers are receiving chambers called the right and left atrium. The other two chambers are pumping chambers called the right and left ventricle. The efficiency in the cycle of blood depends on the sequential contraction

Sheep's heart dissection Lab report Introduction: In this lab, we examined the internal and external structures of a sheep heart. A heart is a muscular organ that pumps oxygenated blood throughout the body using the circulatory system. There me up to four chambers (as in mammals) which contain two atriums and two ventricles. A sheep being a mammal includes these qualities. A sheep's heart is made up of

Heart Dissection I. Purpose The purpose of this lab was to practice dissection skills and to further our knowledge of the heart. From this lab we learnt about the parts and functions of the heart. For example, the different chambers, the veins, and the arteries that all run through the heart. Through careful observation we were able to identify all of the main parts of the heart that keep blood pumping through our body and were able to determine the important structures. Because of this lab

1. Discuss your dissection of the sheep heart and the cardiovascular system of the fetal pig by doing the following: a. Describe the similarities and differences between the fetal pig heart and the sheep heart. Differences: 1. Size 2. The left ventricular wall is thicker in the sheep than the fetal pig. Similarities: They both have 2 atria and 2 ventricles. b. Describe the four valves of the heart, including their name, location, and function. The four valves of the heart are the tricuspid

2. Discuss your dissection of the respiratory system of the fetal pig by doing the following:DONE a. Compare the structure of the trachea to the structure of the esophagus. The trachea is along the mid-ventral portion of the neck in the thoracic cavity. It has horizontal bands. The esophagus is located and lies dorsal to the trachea and extends through the thorax on the left side. It does not have bands. b. Describe how the structures of the respiratory system (i.e., trachea, bronchi, and lungs)

Task 211.4.4-01-05, 07-09, 11 Nervous System Organization of Nerve Tissue Lab Exercise 1: The Multipolar Neuron A. What is the function of a neuron? Neurons carry and transmit electrical impulses generated by both internal and external stimuli. B. What is the difference between a neuron and a nerve? Neurons are the cells that exchange messages from the internal and external environments. Nerves consist of many neurons that transmit different

English 240 December 16, 2011 Should Animals be used for Research During the past ten years, a major controversy over the use of animals in biomedical and behavioral research has arisen. The debate about using animals for medical testing has been ongoing for years. The struggle is usually between animal rights activists and scientist. I believe that animal testing is imperative to the progression of medical cures, procedures and drugs. Scientists have been solving medical problems, developing

laboratory experiment included observing and learning to identify the structural characteristics, mostly arteries and veins, in the chest cavity of the fetal pig, which would further the understanding of the heart and lungs in most other mammals; another objective was to understand blood pressure and heart rate and the factors that affect it. The objectives of the Gas Exchange laboratory experiment was to observe the respiratory system in the fetal pigs, thus gaining an understanding of the respiratory
