Fat is doing us a favor...You may need to look up some of the answers on the internet or your book. (1) Liposuction suctions out adipose tissue. What is adipose tissue?
 * adipose tissue is fat. it is loose connective tissue that is made up of adipocytes. the main purpose of this tissue is to store energy in the form of fat... but is also cushions and insulates the body.



(2) Define epidemic. (3) Define obesity.
 * a widespread contamination of a certain infectious disease. the rate of infected people has to be well over the "normal" rate of the disease.
 * obesity is when the natural energy stored in the fatty tissues exceeds the normal and becomes linked to health conditions. it is a personal illness. obesity is being extremely overweight.



(4) How could we have an obesity epidemic? (5) What are the main obesity related illnesses? (6) How does the liver protect the body from alcohol?
 * since obesity is considered a disease. people who are obese aren't just fat, they are literally suffering from an illness and addiction to food. this epidemic isn't being spread from person to person by contact, but rather by culture, media, and lack of exercise. this has now become an epidemic since the rate of obesity has triples since the 1980's (well over the expected rate of obesity) and is therefore becoming an epidemic.
 * cardiovascular disease, diabetes (type 2), hypertension and stroke, sleep apnea, and osteoarthritis
 * among the many functions of the liver, (metabolism, glycogen storage, decomposition of red blood cells, plasma protein synthesis) detoxification is one of the main functions. The liver detoxifies the alcohol that enters our body, the only problem is the liver can only detoxify a certain amount of alcohol before it becomes a candidate for liver cancer. if there is too much alcohol... a healthy liver will only create a chemical imbalance... if the liver has to detoxify too much alcohol cells can be destroyed and altered... which leaves the person with fat deposits (a fat liver) or inflammation or even scarring.



(7) Where does excess energy go? (8) Why do we have so much excess energy in our diet? (9) If we didn't have adipose tissue where could we put the excess energy? Is this OK? (9) Humans have much more body fat than our closest relatives the chimpanzees. What is a possible evolutionary reason for this? (10) Adipocytes (Fat cells) are filled with fat called. Describe the triglyceride structure and why it contains so much energy.
 * the unused energy is usually stored as fat in the fatty tissues. food with mainly fat can efficiently be stored... while food with carbohydrates cannot.
 * There are too many calories in the food that we eat. we intake empty calories without even realizing it.
 * we would have to store the fat in the liver. this wouldnt be okay because the liver would then start to swell. we could suffer from liver failure and liver-related deaths.
 * since we have a larger brain than the chimpanzees we need more fat so that our brain can have food even when there isnt any food... so the brain can feed off of the stored fat when there isnt any other source of food.
 * triglyceride is a greasy fat made up of three fatty acid chains of mainly carbon and hydrogens and are arranged in high-energy configurations... it is vegetable oil and animal oil.



(11) What happens to adipocytes when we gain weight? (a lot of weight) (12) Adipose tissue can be an endocrine gland too. Which hormone do adipocytes release, and how does this signal the body that it is time for puberty?
 * we stretch the adipocytes out... because they absorb high-energy lipids... they then divide and create more... causing the adipocytes to stretch.
 * they produce the hormones leptin, resistin, and the cytokine TNF... liptin is only found in girls... it signals the brain to release the pulsing axis gonadal hormones... this starts puberty.
