Earth & Space Physics & Engineering Sheep Heart Dissection Guide Project Sheep have a four-chambered heart, just like humans. By studying the sheep's anatomy, you can learn how your own heart pumps blood through your body, thereby keeping you alive! Use this sheep heart dissection guide in a lab for high school students. 2. Locate the coronary arteries and veins that are on the surface of the heart. 3. Find the flaps of dark tissue on the top of the heart. These ear-like flaps are called auricles. 4. The front-most vessel is the pulmonary trunk. Place a probe or pencil in this vessel to mark its place. 5.

Atrium = Singular Atria = Plural Vena Cava = Singular Vena Cavae = Plural The three (3) layers of the heart wall: epicardium, myocardium, endocardium Pericardium SHEEP HEART DISSECTION PROCEDURE: Identify all major structures of the heart highlighted below and follow the path of blood through the heart. Sheep have a four-chambered heart, just like humans. By studying the sheep's anatomy, you can learn how your own heart pumps blood through your body, thereby keeping you alive! Use this sheep heart dissection guide in a lab for high school students. 1. Cut open sheep hearts with a provided paring knife. It is easiest to hold the hearts with one hand, apex side up (large vessels down). Start by bisecting just less then halfway down through the muscle (separating the front of the heart from the back). This will allow the students to see inside the heart. The sheep heart is an excellent specimen to use for comparative human anatomy in both size and function. The sheep heart is mammalian, having four chambers like the human heart, which includes two atria and two ventricles.

Sheep Heart This page contains photos of the sheep heart dissection. All the major vessels are represented, many are labeled with colored pencils so that you can see exactly where each is located. The heart can be confusing because it is not perfectly symmetrical. Students often confuse the left and the right side of the heart. external sheep heart diagram on page 3.. Remember that each side of the heart is labeled according to the side of the animal's body in which it is located. The heart's right side will be on your left and the heart's left side will be on your right. ___ 4. On the tray, point the apex of the heart toward you. Identify the chambers of the heart and the major blood vessels that lead into and out of those chambers Trace the path that blood takes through the heart Pre-lab: 1. Label the heart diagrams (dorsal and ventral sheep heart views) on the last page of this lab. (Parrot pp. 948-951, Dragonfly pp. 943-950). 2. Students use this dissection guide to learn the anatomy of the heart, using a sheep as a model. The sheep heart is similar to a human, and students can identify the major vessels: aorta, pulmonary artery, pulmonary vein, and the vena cava. The guide includes instructions on how to determine which side of the heart is the ventral (front) side by searching for the auricles and the.

SHEEP HEART IMAGES Sheep Heart Unlabeled Sheep Heart Leader-lined Sheep Heart Labeled San Diego Mesa College offers various certificates and degrees to prepare students for careers relating to Biology. Heart External Anatomy Place the preserved heart on your dissecting tray. Using your forceps, remove the fat that covers the upper part of the heart and blood vessels. The fat is light colored, soft, and without structure. Locate the external structures labeled on the anterior and posterior sides of the heart, as shown below. Heart Internal Anatomy
Lab guide outlining the procedure for dissecting the sheep's heart. It includes photos to diagram where major vessels are and where incisions should be made to view internal structures, such as the mitral valve and papillary muscles.. ** Compare the heart of the sheep to human hearts by viewing various heart models in the room. Label the. Pins Pins are used to hold the heart in place during dissection and labeling. Labels Labels are used to identify different parts of the heart, such as the atria, ventricles, and valves. Marker A permanent marker is used to write labels on the heart. Each material's purpose is essential for successful and accurate labeling of the sheep heart.
