It includes instructions, images and steps to complete the lab; includes external anatomy, digestive system, circulatory system, and urogenital system. Abdominal cavity. Systemic and The pig in figure 1 is lying on its dorsal side. Systemic and Because it is a portal vein, it will not have received any latex paint. Main organ of circulatory system; pumps blood to all regions/muscles of the body through a system of veins and arteries Pericardial Sac Membrane that covers surface of the heart Study with Quizlet and memorize flashcards containing terms like fetal pig heart: right auricle, left auricle, right ventricle, left ventricle, pig pulmonary artery, pig aortic arch and more. With proper directions, they can all be readily found, especially with large, full term fetal pig specimens. Next: The heart and lungs . Stomach and liver lifted to show the pancreas. Trace the oviducts toward the posterior to find that they merge at the uterus. Later in life, the thymus decreases in size and becomes fairly unimportant. These typically are quite small in the fetal pig. lumenlearning. ) First observation regaring the fetal pig circulatory system was the size comparison of the body and organs upon dissection. Cardiac muscle that pumps blood through vessels to carry nutrients, hormones, metabolic waste, and gases to and from organs and cells, loading and unloading takes place in capillaries, oxygen is added to capillaries in lungs, nutrients to capillaries in small intestine, blood is detoxified in capillaries in kidneys Jul 11, 2023 · 10. Explore the digestive, respiratory, circulatory, and urinary systems of the pig and compare them with humans. The pig in figure 1 below has its ventral side up. Aorta : Large artery that leaves the heart and supplies blood to the body This is a handout for use during the fetal pig dissection. 1.

During this lab, you will learn about the anatomy of the pig as an example of a vertebrate mammal, identify structures on the pig and know their functions, and identify structures that are a part of the digestive system, respiratory system, circulatory system, reproductive system, and excretory system. The circulatory system (also called the cardiovascular system in mammals) of the pig is responsible for the transportation of nutrients, gases, wastes, and hormones. receives oxygenated blood from the left atrium via the mitral valve, and pumps it into the aorta via the aortic valve; shorter and more conical in shape than the right The hypothesis about what parts of the fetal pig circulatory system would be seen during. There are a some differences in structural details, mostly relatively minor in nature. When the fetal pig was dissected the heart was found easily, but it was difficult to observe where the four chambers of the heart are located (Figure 2). Use figures 1–4 below to identify its sex. In this view, the thoracic portion has been reflected from the midline to the pig's left. Several different pig dissections were used to obtain the photographs below. Blood vessels that branch from the aorta carry blood to most of the body. Figure 26. com Circulatory System: Heart: The heart is a four-chambered organ (two atria, two ventricles) that pumps blood. Study with Quizlet and memorize flashcards containing terms like what are the three types of blood vessels, define artery what type of latex is it injected with, define vein what type of latex is it injected with and more. Figure 27. Successfully complete dissection of the fetal pig. Digestive system with cecum lifted. Figure 22. The coronary artery runs on the ventral surface of the heart (shown here from the labeled line to the yellow dot and further to the pig's right). Jul 11, 2023 · Circulatory system The drawing below shows some of the major arteries that carry blood to the body. It is opposite the dorsal side. (Hint: Your response should be 6-10 sentences. Circulatory System. -Pumps blood to all the muscles in the body through a system of blood vessels-Right side pumps blood The is one of the four chambers of the heart. Some examples are […] Circulatory System Objective -Trace the pathway of oxygen and carbon dioxide into and out of the lungs of a mammal, identify the major blood vessels of a fetal pig the pig, also locate, name, and describe chambers the functions of the chambers of the heart. 1: Fetal Pig Dissection Lab In this lab, you will perform a dissection of a fetal pig. The pig has a circulatory system that is quite similar to the human circulatory system. Additionally, it is involved with the control of body temperature, provides channels for the immune system to protect the body, and participates in the maintenance of body fluid See full list on courses. Obtain a fetal pig and identify the structures listed in figure 1. Female: In the female pig, locate two bean-shaped ovaries located just posterior to the kidneys and connected to the curly oviducts. Digestive system with liver in place. It is responsible for carrying food and oxygen to every cell in your body. This blood vessel supplies oxygenated, nutrient-rich blood to the ventral portion of the heart (a dorsal artery does the same on the opposite side). Ventral is the belly side. Pigs like other mammals have a four-chambered heart. Learn at your own pace with bite-sized, verified content. Write a paragraph describing the features of the fetal pig circulatory system you observed. As the name suggests, this system is responsible for circulating blood and nutrients throughout the body.
