Slide 2 (gulp) But sheep have nice hearts Slide 3 Supplies you will use: Slide 4 Scalpel Blade Slide 5 Scalpel Handle Slide 6 Surgical Scissors Slide 7 Hemostats Slide 8 Dissection Tray & Pig Heart Dont forget your gloves! Slide 9 Slide blade on scalpel handle Slide blade on scalpel handle. Peel back blade packet halfway. Slide over narrow tip of scalpel handle. Slide 10 Scalpel is now ready for dissection. Slide 11 Slide 12 Base Apex Slide 13 Auricles Rt.Lt. Ear-shaped extensions of the atria. Slide 14 The auricles wrap around to the anterior side of the heart. Anterior Slide 15 The Coronary Vessels The cardiac muscle receives oxygen for metabolism and releases waste products into coronary vessels. Slide 16 Anterior View Slide 17 The Great Vessels The large veins & arteries, which transport blood to and from the heart muscle. Slide 18 Locating the great vessels: Slide 19 Anterior View--Aortic Arch Aorta Arising from the left ventricle of the heart is the largest artery of the body, the aorta. Rt.Lt. Slide 20 Anterior View--Aortic Arch Brachiocephalic trunk (innominate artery) Rt.Lt. Lt. common carotid Slide 21 Aorta: Posterior ViewAorta Lt. Rt. Slide 22 Posterior View--Vena Cavae Superior Vena Cava Inferior Vena Cava Lt.Rt. Slide 23 Posterior View--Pulmonary Artery Lt. Pulmonary Artery Lt.Rt. Slide 24 Posterior View--Pulmonary Veins Pulmonary veins are inferior to pulmonary arteries. Rt.Lt. Slide 25 Rt. Pulmonary Vein Lt.
