"9527, hand in your homework!"

"The fourth assignment was completed, good, the finished quality was average, the design style was simple and crude, but there was a certain innovation; Although you have already started to try to learn to create, you still have a long way to go, so work hard to be a perfect student, boy! Overall evaluation: 5 credits. Pen & Fun & Pavilion www.biquge.info"

"Huh~~It's not bad~~~" finally got a good, Meng Yang felt a sense of accomplishment.

"Get carried away! Since you've just made progress, let's take note of this shock warning for now. 9527 came quietly.

Ga-

Like a bucket of ice water pouring head-on, the little excitement in Meng Yang's heart came to an abrupt end...... 9527 can't see him happy......

"Slander! Warning once! ”

Ok，ok！

Meng Yang hurriedly stopped, this kind of thinking is unacceptable, and if you are not careful, there will be serious consequences.

"The fifth operation, through genetic modification, to enhance the digestive and respiratory performance of organisms, lasted two days."

It's still a similar job, it seems that all the major systems of the organism need to be modified!

"That's right!"

Meng Yangmu has any way, his thoughts are completely transparent, but whenever he thinks of something, there will be praise and interjections in his mind at any time, it is really a bit of a renquan, and he doesn't care about other people's privacy at all......

"Would you talk to the ants about renquan?"

...... Well, whatever......

The respiratory and digestive systems, which seem to be designed to enhance energy absorption and supply, are clearly matched by the strengthening of the muscles and circulatory system.

Then let's use the tiger girl as an experimental subject, anyway, it is estimated that there will be no time to design an improvement plan for the second creature.

Digest, breathe!

Breathing is easy to do, it is nothing more than increasing the volume of the lungs, increasing the gas exchange efficiency of the lungs, this expands the chest cavity of the tiger girl, strengthens the strength of the chest diaphragm, and increases the strength of the respiratory muscles.

As for enhancing the ability of gas permeation, increasing the exchange capacity between the blood and the alveoli, and increasing the osmotic efficiency......

Meng Yang suddenly thought of a point, in the process of exhaling and exhaling the lungs of living beings, a considerable part of the gas does ineffective repeated movements between the trachea and the respiratory tract, and only the part of the gas that enters the alveoli has the opportunity to exchange gas with the blood.

In other words, in a 100-liter gas exchange, only 50 liters or less may actually enter the alveoli, and most of the gas leaves the organism with exhalation before entering the alveoli. This is a huge waste and a great hindrance to respiratory efficiency.

If you improve the lungs of the tiger girl......

Meng Yang really dared to think of anything, anyway, he was experimenting on cats, which was a bit fearless.

After pondering for a long time, Meng Yang finally had the audacity to add a trachea to the tiger girl, changing the tiger girl's lungs into an intake trachea and an outlet tube. Not only do there are two trachea, but even the bronchi have two sets out, and valves are added to the trachea as air valves, and then respiratory muscles are added to the outer wall of the alveoli.

After such a change, the lungs of the tiger girl have become the structure of the bellows, and each alveoli has become a separate bellows, in other words, the breathing of the tiger girl has been able to get out of the original mode of one exhalation and one inhalation, and different alveoli can be linked, in a continuous breathing state.

But if you do this, there is still a little problem, Meng Yang finally thought about it, and simply divided the nostrils of the tiger girl into labor, one nostril is responsible for inhaling, one nostril is responsible for exhalation, and the throat is equipped with an adjustment device, so that the exhalation and inhalation will not be delayed.

But what if you choke?

When coughing, the airflow plays a role in expelling foreign bodies, and the lungs of the tiger girl become bellows, so it is a one-way airflow, what should I do if I encounter a foreign body choking into the trachea?

...... This thing

Meng Yang thought about it, and simply added a connection valve at the bottom of the trachea, once the situation of choking is encountered, the airway will be connected with the intake, which can effectively solve the problem of choking.

Meng Yang is purely using the tiger girl's body as a machine to explode indiscriminately, which means that the ups and downs of the tiger girl don't know, otherwise he will definitely scratch his face.

The respiratory system was revised, and finally the tiger girl's chest cavity became 20% larger, the lungs suddenly increased a lot of respiratory muscles, the trachea increased a lot, the neck became a lot thicker, and the nostrils and nasal cavity became larger and more open......

Various ......

As for the digestive system......

Meng Yang thought about it for a while, and felt that the tiger girl only had fangs to bite things, and the food was not completely cut, which was the characteristic of carnivores, and there was no kind of grinding teeth of herbivores.

If the tiger girl's teeth are changed, it is easy to be found to be abnormal from the appearance, in this case, Meng Yang simply added some grinding structures similar to folds in the tiger girl's stomach, which can be like a grinding disc to further grind the food residues.

In order to increase the digestive ability of the tiger girl, Meng Yang looked for the digestive enzymes of various creatures, and then picked the good ones and desperately added them to the tiger girl, not only to increase the variety, but also to increase the quantity, so that the food in the tiger girl's digestive tract can be decomposed at the fastest speed.

Strictly speaking, food is an organism, and in fact, it can be completely decomposed into various organic matter, which can be turned into nutrients, but food cannot be completely decomposed in the digestive tract of living organisms, so there is the production of feces.

Increase the length of the digestive tract of the tiger girl, increase the folds in the digestive tract, and additionally borrow the pattern of polyps to add countless small digestive vesicles similar to polyps in the digestive tract.

Once food enters the digestive tract, these vesicles act like polyps, trapping food debris into the vesicles, and then slowly melting and decomposing with digestive juices, eventually completely breaking down and absorbing the food debris.

In order to enhance the efficiency of absorption and digestion, the stomach of the tiger girl has become more complex, no longer simply secreting gastric juice, a lot of digestive juice is injected directly into the stomach, and after the stomach and food are fully stirred, the chyme enters the intestine and is directly captured by the vesicles on the intestinal wall.

In this way, the vesicles do not have to secrete a variety of digestive juices, and the chyme that has been fully stirred with various digestive juices can be further decomposed in the vesicles, and then directly absorbed into the body of the tiger girl through the intestinal wall.

Another advantage of this mode is that the digestion speed is very fast, and the stomach stirs for an hour, and it can be directly absorbed when it enters the intestines.

Increase the density of blood vessels in the intestine and increase the permeability of blood vessels, so that nutrients can enter the blood with higher efficiency, and at the same time increase the blood flow rate near the intestines, so that nutrients can be replenished more quickly in the areas where they are needed.

After such a toss, the stomach plus grinding structure, the intestine plus vesicles, plus a variety of super digestive enzymes, I believe that the digestion efficiency of the tiger girl will be directly improved by several grades.
