1 00:00:00,560 --> 00:00:06,500 Hello, I am Nailia and I am Sara and we are going to present a project of biology, the dissection of the heart. 2 00:00:10,500 --> 00:00:13,679 The heart is the most important part of our body. 3 00:00:14,259 --> 00:00:21,359 The pumpet part is the front part while the plant part is how we see it from the back. 4 00:00:21,879 --> 00:00:25,519 This is the left ventricle of the heart and this one is the right. 5 00:00:25,519 --> 00:00:36,200 They are separated by the septum and this is the left artrum while this is the right 6 00:00:36,200 --> 00:00:47,950 artrum and this is the aorta which has three different holes. 7 00:00:47,950 --> 00:01:04,680 Now we introduce the forceps in the pulmonary vein which ends in the right ventricle. 8 00:01:04,680 --> 00:01:14,849 Now we are going to cut the right part of the heart. 9 00:01:14,849 --> 00:01:20,599 Now we can see the tripus valve and its ligaments. 10 00:01:20,599 --> 00:01:25,840 Now we are going to cut the left part of the heart and we introduce the forceps in the 11 00:01:25,840 --> 00:01:37,379 pulmonary artery and we cut parallel to the septum, like this way. 12 00:01:37,379 --> 00:01:44,260 This part is much harder to cut because it has more tissues than the other part. 13 00:01:44,260 --> 00:01:50,480 This part, as I said before, it has lots of more tissues than the other part because it's 14 00:01:50,480 --> 00:01:59,159 the part which bulbs up this blood from the artery aorta it carries out the 15 00:01:59,159 --> 00:02:12,280 blood in most parts of all our body now here we can see the mitral valve this is 16 00:02:12,280 --> 00:02:28,050 a blood plot here in this video we can see better the mitral valve and its 17 00:02:28,050 --> 00:02:39,159 tendons now we introduce the forceps in the pulmonary vein and we can see that 18 00:02:39,159 --> 00:02:42,159 and lives in the right ventricle. 19 00:02:44,159 --> 00:02:47,159 The aorta is the main artery of the human body. 20 00:02:48,159 --> 00:02:52,159 It leaves the heart by the ascending thoracic aorta 21 00:02:52,159 --> 00:02:54,159 and descends throughout the chest, 22 00:02:54,159 --> 00:02:56,159 through the descending thoracic aorta 23 00:02:56,159 --> 00:02:58,159 and then runs through the abdomen, 24 00:02:58,159 --> 00:03:00,159 by the abdominal aorta. 25 00:03:00,159 --> 00:03:04,159 And here we can see the two parts which we have cut. 26 00:03:04,159 --> 00:03:11,780 So we use the heart, the gloves, the tray, 27 00:03:11,780 --> 00:03:31,259 the scalpel, the scissors and the forceps also we cut lungs this is where the 28 00:03:31,259 --> 00:03:37,599 gases change between blood and air takes place in our body we need oxygen to 29 00:03:37,599 --> 00:03:52,639 perform the third respiration in this part we blow up the lungs to see how 30 00:03:52,639 --> 00:04:04,960 they work and that's the end 31 00:04:08,719 --> 00:04:10,719 Okay, let's continue. 32 00:04:10,719 --> 00:04:12,719 What do we do now? 33 00:04:26,139 --> 00:04:28,139 The music is awesome. 34 00:04:28,139 --> 00:04:30,139 It's awesome. 35 00:04:39,579 --> 00:04:48,269 And that's the end. 36 00:04:48,269 --> 00:04:51,410 If you liked the video, give it a like and subscribe. 37 00:04:51,410 --> 00:04:53,230 See you the next time, bye!
