<span>a. Rollerblading
Exercise that strengthens your heart and lungs is called aerobic exercise. And in order for aerobic exercise to work, you need to elevate your heart rate for at least 20 to 30 minutes. So let's take a look at the various exercises listed and see what each does.
Rollerblading - Moderate amount of effort, but happens over an extended period of time. Definitely aerobic, good candidate for the correct answer.
Pull-ups - This helps strengthen the upper back, shoulders, lats, and abs. Useful for building muscle strength, but not very aerobic. Not the correct answer.
Push-ups - Strengthen the chest, shoulders, and triceps. Another exercise for building strength, but not aerobic. Not the correct answer.
Rock Climbing - Helps build agility and strength. But also not very aerobic. Also not the correct answer.
So of the four exercises mentioned, only one of them involves sustained moderate effort over an extended period and that's rollerblading which is the correct answer.</span>

The correct answer would be, I need a diet without a lot of fatty foods.

The above mentioned statement by the patient indicates the understanding of the discharge instructions.

Laparoscopic Cholecystectomy Surgery, is a surgery in which the gallbladder of a person is removed. Gallbladder is a small organ which is located in the liver of a human body. Gallbladder is an organ which helps in the digestion of food.

A greenish fluid like substance, called as bile is produced in the liver and is stored in the gallbladder, which is used later to digest the fatty foods.

So when the gallbladder of a person is removed, he must take care of his food intake and avoid eating the fatty foods, as his liver won't be able to digest it properly due to the absence of gallbladder.
