1 00:00:06,639 --> 00:00:25,839 excretory system. What do you already know? You already know there are three 2 00:00:25,839 --> 00:00:41,189 vital functions nutrition, interaction and reproduction. Interaction. We have 3 00:00:41,189 --> 00:00:48,409 five senses and each sense has an organ. We use our senses to recognize what is 4 00:00:48,409 --> 00:01:01,009 happening around us. They are hearing, sight, smell, touch and taste. There are 5 00:01:01,009 --> 00:01:06,950 two systems that take part in the process of interaction. They are the 6 00:01:06,950 --> 00:01:15,209 nervous system and the locomotor system. Our senses work together with our 7 00:01:15,209 --> 00:01:22,409 nervous system in the life process of interaction. Our locomotor system is made 8 00:01:22,409 --> 00:01:30,290 up of bones, muscles and joints. It uses nutrients from food and oxygen to work. 9 00:01:30,290 --> 00:01:41,099 We use our locomotor system to move, eat and speak. Our bodies need nutrients from 10 00:01:41,099 --> 00:01:49,579 foods to live and grow. There are five different types of nutrients. Carbohydrates. They give us 11 00:01:49,579 --> 00:02:02,159 energy. Don't eat sugary cereals. Eat wholemeal bread. Fruit and vegetables. Fruit and vegetables 12 00:02:02,159 --> 00:02:12,419 contain minerals and vitamins that are essential for our health. Cetic fruits, oranges, limes and 13 00:02:12,419 --> 00:02:18,780 lemons contain vitamin C that prevent you from getting colds. You should eat 14 00:02:18,780 --> 00:02:30,439 five fruits and vegetables a day. Proteins. Pulses, fish, meat and dairy. Protein 15 00:02:30,439 --> 00:02:37,580 helps you grow. Proteins build tissues and organs of the body. Milk and cheese 16 00:02:37,580 --> 00:02:47,409 contain calcium that help you have strong bones and teeth. Dairy and 17 00:02:47,409 --> 00:02:53,710 alternatives milk and cheese contain calcium that help you have strong bones 18 00:02:53,710 --> 00:03:04,939 and teeth fats healthy fats are essential for our bodies they give 19 00:03:04,939 --> 00:03:11,039 energy to ourselves and some organs need them to function like the brain and the 20 00:03:11,039 --> 00:03:21,189 heart digestive system how can we get these nutrients from food there is one 21 00:03:21,189 --> 00:03:31,860 system that obtains nutrients from food. This system is a digestive system. Our digestive 22 00:03:31,860 --> 00:03:42,460 systems help us get the nutrients from food. Let's watch this video to see how the digestive system 23 00:03:42,460 --> 00:03:56,069 works. Hello friends and welcome to a new happy learning video. Today we're going to learn about 24 00:03:56,069 --> 00:04:02,229 the digestive system and digestion so that our body can make the most of the food we eat 25 00:04:02,229 --> 00:04:09,110 it must first transform itself into a simple substance called nutrients these nutrients are 26 00:04:09,110 --> 00:04:15,110 then transported by our blood around our body to be used and converted into energy 27 00:04:16,870 --> 00:04:23,110 this food transformation process is called digestion and is done in the digestive system 28 00:04:23,910 --> 00:04:29,930 The digestive system is a very long tube through which the food travels and is made up of the following parts. 29 00:04:30,730 --> 00:04:33,810 The mouth, this is where the digestive journey begins. 30 00:04:34,730 --> 00:04:37,629 The teeth both chop and grind up the food we eat. 31 00:04:37,930 --> 00:04:42,149 Once it has been made into a ball, it is pushed down the food pipe to the pharynx. 32 00:04:42,149 --> 00:04:46,829 The pharynx is a cavity which shares the digestive system with the respiratory system. 33 00:04:48,170 --> 00:04:50,670 It is from the pharynx that the food goes to the esophagus. 34 00:04:50,670 --> 00:04:56,290 The esophagus is a soft muscular tube that moves food further down to the stomach. 35 00:04:57,250 --> 00:05:00,009 The stomach is a widening of the digestive tube. 36 00:05:01,069 --> 00:05:05,389 It creates a movement which allows food with a mixture of gastric fluids. 37 00:05:06,209 --> 00:05:10,350 Once this process has been done, it then travels to the small intestine. 38 00:05:11,110 --> 00:05:14,910 The small intestine is called small because of its width, not its length. 39 00:05:14,910 --> 00:05:20,329 It is actually a lot longer than the large intestine, measuring up to 7 meters in length. 40 00:05:20,670 --> 00:05:23,649 Almost as wide as a football goal from post to post. 41 00:05:24,129 --> 00:05:28,589 Well, it is here in the small intestine where the food digestion journey ends. 42 00:05:28,970 --> 00:05:33,610 Now it is up to fluid processes by two glands, the liver and the pancreas, 43 00:05:33,910 --> 00:05:37,310 to finalize the transformation from foods to nutrients. 44 00:05:37,610 --> 00:05:42,870 Once the food is converted into nutrients, they then traverse the small intestine's walls 45 00:05:42,870 --> 00:05:48,069 and filter into our blood where they are then made good use of by all of our body's cells. 46 00:05:48,069 --> 00:05:51,550 But what happens to the food that our body doesn't need? 47 00:05:52,209 --> 00:05:57,389 All that, such as fiber, for example, is transferred into the large intestine. 48 00:05:59,860 --> 00:06:05,839 The large intestine is a thick tube which accumulates substances which our organism cannot digest, 49 00:06:06,160 --> 00:06:09,600 and it is where water from these substances is absorbed. 50 00:06:11,120 --> 00:06:18,060 The substances then form fissile matter, or what we call poop, and it comes out of the anus. 51 00:06:18,060 --> 00:06:24,060 Ah, it sounds a little bit disgusting, but that's how our body works. 52 00:06:24,060 --> 00:06:30,060 Anyway, friends, I hope you found the digestive system and digestion as interesting as I did. 53 00:06:30,060 --> 00:06:35,060 See you later and don't forget to subscribe to Happy Learning! 54 00:06:57,949 --> 00:07:06,949 Our excretory systems or urinary systems help our bodies to remove waste products and excess of water. 55 00:07:06,949 --> 00:07:13,949 If you want to know more about this system, have a look to these two videos. 56 00:07:24,100 --> 00:07:28,100 Hey friends, excuse me. 57 00:07:36,569 --> 00:07:40,569 It feels so good to attend the call of nature. 58 00:07:40,569 --> 00:07:45,750 Hey, I'm sorry to leave you in the middle of our conversation 59 00:07:45,750 --> 00:07:51,649 But it always is important not to hold your pee for a longer period 60 00:07:51,649 --> 00:07:55,029 As it might cause certain complications 61 00:07:55,029 --> 00:08:01,069 But first, it's essential to know how your urinary system works 62 00:08:01,069 --> 00:08:05,949 So, without wasting more time, let's zoom in 63 00:08:05,949 --> 00:08:12,050 The urinary system comes into play for the disposal of liquid waste 64 00:08:12,050 --> 00:08:18,449 Our bodies keep generating a lot of hazardous and unwanted liquid waste 65 00:08:18,449 --> 00:08:25,430 These are toxic waste products which will circulate in our blood until disposed of 66 00:08:25,430 --> 00:08:33,549 And as excess water can be waste too, our body gets rid of it through the urinary system 67 00:08:33,549 --> 00:08:36,389 So, how does it work?
