As you can see this is the heart of frog present on the anterior side heart is covered with a layer of membrane that is called pericardium as you can see the pericardium here is the layer of the pericardium I have caught it with the arrow head needle and I am pointing the needle over the cardium of the heart when we perform dissection we can see the blood of the frog it colours red due to the presence of hemoglobin in the blood all the arteries in the skin and the skeletal muscles therefore white oxygen to the organs this is the ventricle of heart if we turn the heart then we can observe the artery of heart here is the artery heart is three chambered structure that contains two artery and one ventricle as you can observe that heart is beating even though we have performed the dissection of the heart after the observation of heart we will observe the structure of lungs that are connected to the heart these are the lungs as you can see these lie very close to the heart lungs are present in the frog single circuit circulatory system present in the frog all the blood that is collected into the artery of the heart enters into the ventricles and then it goes into the lungs for exchange of gases as you know during respiration carbon dioxide removes from the body the heart takes oxygen from the lungs so that cells can survive in the presence of oxygen and can take energy in the presence of oxygen after this we will observe the structure of liver liver consists of three loaves this is the left lobe this is the right lobe and the middle one is the median lobe attached to the liver is gall bladder gall bladder helps to secrete the secretions that helps in the digestion of the food in the stomach and small intestine apart from the digestion of food liver also store glucose in the form of glycogen so that it can be used at the time of high consumption of energy when no food is available for the animal after doing observation of the heart lungs and liver we will do the observation of the organ that is the part of the digestive system of the frog for this observation we will first remove some organs so that we can clearly observe the organs that are behind the upper organs on the lower side that are present on the lower side to remove the organs we will first attach the skin with the common pins we will take common pins our dissecting tray to put our organs in this tray we will first take common pin and attach it to the skin after assembling the skin of the frog we will remove the liver so that we can easily observe the stomach of the frog after removing the liver we will observe the parts of the digestive system first of all we can see that there is a large sac-like structure that is called stomach stomach is connected to the esophagus esophagus is connected to the order cavity food enters into the mouth then comes into the esophagus after entering into the esophagus it enters into the stomach initial digestion of the proteins takes place in the stomach and this is the heart structure that is the pyloric sphincter of stomach stomach leads to the small intestine all the absorption of the food that is digested completes in the small intestine this is the small intestine attached to this stomach part and the small intestine is the pancreas pancreas helps in the digestion of food small intestine is the most elongated structure that is present in the digestive system small intestine leads to the broad part that is called the large intestine large intestine leads to the rectum rectum stores the waist of the digestive system and it leads to the opening of the frog that is called Kleoka Kleoka is the opening that not only for the release of digestive waste but it also helps to release the gametes of the frog as well as the waist of excretory system like urine along with the small intestine and large intestine the plane is present it is not only the part of immune system that helps to fight with the extra bodies that enters into the body and can cause diseases but it also helps in the formation of blood cells after this plane we can observe irregular shape dark reddish color curved organs that are called kidneys and along with the kidneys oval shaped structures are present that are called testis and they are two in numbers they help in the reproduction of frog this heart structure is the vertebral column of the frog that helps to the frog in the movement along with the vertebral column as you can observe there and the stomach mizin freeze are present and also a very major blood vessels that leads from the heart to all the organs of the frog so that blood can be supplied to all the organs and survival of the frog can be possible students today we have performed frog dissection dissection is the most important thing that we have to take the frog is life frog and before dissection you can apply two methods you can do the pitting of the frog you can damage the brain of the frog or you can give it chloroform and disable the movement we have first observed the frog's external parts what was present in the external parts we have observed we have observed its dorsal surface, its ventral surface, its limbs, its mouth, bulging eyes, external nears we have observed all this in its external part after that we have performed its dissection what we have observed in its first dissection is the blood vessels which were attached to its skin after that we have observed on its abdomen thick layer of muscles that is called calytal muscles after that we have cut the calytal muscles and we can see its internal organs first we have observed the heart with the heart we have observed the lungs after that we have observed the liver with the liver attached to the gall bladder all these things help in circulation and digestion after that we have seen that we can see a slight structure which is called stomach it is connected with esophagus and below it is connected with small intestine small intestine leads towards a broad part which is called large intestine large intestine is used to store all the waste in the rectum and it is used in the colioca after that we have observed some parts like the pancreas which helps in digestion, thepline which helps in immunity as well as in the formation of blood cells after observing all the internal organs what we have to do we have to remove the pins which are attached to the limbs we have to take a plastic bag and we have to discard the frog properly we will remove thumb pins from the limbs that we attached at the start of this dissection we will take help of foresap to accurately remove the pins we will take a plastic bag to discard the fog we will just pick the fog, carefully put it in the plastic bag we will discard the fog like this and we will put it in the dust bin now you have to wash your dissection board and all the operators that you have used in your dissection and clean the table with 70% ethanol thank you
