0:00 Hello, students.

00:01 Now, in this question, they have asked, thick, soupy liquid of partially digested food that will leave the stomach.

00:10 What is this called as? now, if we observe, they have given that it is already digested food.

00:17 So they are not asking the one that is entering the food, entering the stomach rather, right? they are asking the one that is leaving the stomach.

00:27 So what is it? it is called the khaim right so it is option d which will be our answer in this case so that is why we will write our answer as option d for the first question that they have given here coming to the second question they are asking which of the following is not a direct function of the digestive system is it to eliminate indigestible remains to protect against pathogens, to absorb nutrient molecules, to digest food into small nutrients so that the molecules can pass through the membranes or to ingest the food.

01:06 Now, what is the main agenda of digestive system? it basically helps in the digestion process as a result of which small molecules can be passed through membranes and reach the tissues as nutrients.

01:22 Right.

01:22 So, we can observe that the second option is telling quite differently about the function of the digestive system to protect against the pathogens.

01:34 Now, if you observe digestive system, some part of the digestive system contains some micro will lie as well, right? so, these kind of structures will help to protect against the pathogen.

01:47 So we can say that the answer for the second question would be option b.

01:52 That is why i'm going to be marking that as our answer.

01:56 Coming to the third question.

01:59 In the third question, they're asking what is the function of large intestine? or rather, what does this large intestine do? now, large intestine, all it does is it stores the feces and it reabsorbs the water.

02:16 Reabsorption of water that you observe occurs from the body.

02:21 Body reabsorbs the water from the large intestine as a result of which the feces is very solid right so that is what large intestine does right mixing food with pancreatic enzyme these are all done by the other parts of the digestive system so what does the large intestine do it will store feces and reabsorbed water which happens to be the third option that is why we will mark that as our answer for this question coming to the next question...
