5Define exercise economy                                                                                                   

Answers

Answer:

1. pulmonary diffusion, cardiac output, and blood volume and flow

2. muscle diffusion capacity, and capillary density

3. Kravitz and Dalleck believe that both the central and peripheral limitations limit VO2max, although the relative importance of each component is being discussed, researched and debated.

4. The lactate threshold refers to the intensity of exercise at which point there is an abrupt increase in blood lactate levels resulting in the exercising muscles to become fatigued.

5. Exercise economy can be defined as the oxygen consumption that is required by the body to perform a given exercise.

Explanation:

1. The central limitation of maximum oxygen uptake (VO2max) refers to the limitations of the cardiovascular system to transport oxygen to the exercising muscles.

The three central limitations to aerobic capacity are:

pulmonary diffusion,cardiac output, andblood volume and flow

2. Peripheral limitations refers to those factors which limit the ability of exercising muscles to extract and utilize oxygen, which has been transported by the cardiovascular system.

Two of these limitations include:

muscle diffusion capacity, and capillary density

3. Kravitz and Dalleck believe that both the central and peripheral limitations limit VO2max, although the relative importance of each component is being discussed, researched and debated.

4. The lactate threshold refers to the intensity of exercise at which point there is an abrupt increase in blood lactate levels resulting in the exercising muscles to become fatigued.

In untrained endurance athletes, the lactate threshold occurs at between 50 - 60 % VO2max, whereas it increases to between 70 - 90 % in well-trained endurance athletes.

5. Exercise economy can be defined as the oxygen consumption that is required by the body to perform a given exercise.

Which mental health condition is characterized by extreme behavior which violates the rights of others as well as basic social rules?

Answers

Conduct disorder would be the answer. Hope I could help!

Answer:

A mental health condition that involves extreme behavior and violation of basic social rules is conduct disorder.

Explanation:

The conduct disorder usually begins in childhood or adolescence, and is characterized by the lack of respect for basic rules of coexistence and the rights of others, which makes it an antisocial behavior.

This type of mental condition includes acts such as physical aggression to other people, theft, recurrent cheating or the transgression of established rules at home, the street, school or work.

The most frequent causes of conduct disorders are genetic predisposition, altered brain function, violence or child abuse, among others.  It is frequent that a transgressive and socially unacceptable behavior is related to vandalism and delinquency.

Makes up your physical identity

Your gender height weight and age are the different attributes that make up your Physical identity.

What is Physical identity?

Stamina, flexibility, balance, strength, and coordination are all examples of physical identity. The capacity to learn or retain knowledge, the capacity to comprehend the facts and significance of one's behavior, and the possession of the qualities (capacity, ability, power) necessary to complete a task are all examples of mental abilities.A physical disability, on the other hand, is a condition that limits a person's stamina, dexterity, mobility, and/or physical capacity. These conditions include cerebral palsy and hearing impairments. When a person does not progress cognitively at the same rate as the majority of other people, they have a mental disability. A mental disorder is distinct from a mental disability.The set of cognitive faculties is thought to be made up of an immaterial substance that is separate from and distinct from the body in another conception of the mind. Physical identity may be based on the persistence of this non-physical substance over time, despite the continuous change in the substance of the body it is associated with, if a person is considered to be their mind rather than their body—if a person is then identified with their mind—and if their mind is such a non-physical substance.The explanation of the relationship, if any, that exists between minds or mental processes and bodily states or processes is the subject of the mind-body problem. Philosophers in this field try to figure out how a non-material mind can affect a material body and vice versa.

You are a transplant surgeon who is preparing to do a heart transplant on a young mother. The donor has been identified and the organ is being harvested right now. It should be to you within 12 hours. The timing was good. You do not believe that the mother would have lived much longer without the transplant. You know that there are a number of people on the transplant list that will not be so lucky. When you are discussing the procedure with her husband, you realize that she has recently been exposed to her young daughter who has just come down with chickenpox. She has never had chickenpox before and you are concerned. If you convey this information to the transplant team, she will not receive the transplant. The heart will go to the next match on the transplant list. There is no real reason to expect that she will become ill. However, if she does, it is not likely that she will be able to overcome the virus with the anti-rejection drugs she will be given. She could become very sick and even die. If she does, then the transplant will not go to another.

Answers

Answer:

The muscular system, in vertebrates, is controlled through the nervous system, although some muscles, like cardiac muscle & muscles in stomach walls, can be completely autonomous. And others like, skeletal muscles are under conscious control.

Muscles run throughout the human body. Each muscle has a specific name according to it's location or function. All these muscles work and render human body to function normally. For example, when you want to play flute you have to pucker your lips, you can do so with the help of Orbicularis oris, a muscle surrounding the lips.

Digestive system breakdown the food and absorb nutrients from it.

Food we eat is the body's source of fuel. Nutrients in food give the body's cells the energy they need to operate. Before food can be used it has to be broken down into tiny little pieces so it can be absorbed and used by the body. In humans, proteins need to be broken down into amino acids, starches into sugars, and fats into fatty acids and glycerol. The whole process of digestion is aided by chemical and nervous coordination

.Explanation:

A physician orders meperidine 1.1 mg/kg diluted in 120 mL of water po every four hours as needed for pain for a 66-lb child. In stock: meperidine oral solution 50 mg/5 mL. What volume of medication should be added to 120 mL of water per dose?

Answers

Answer:

The volume of the drug meperidine to be diluted in 120 ml of water per dose is 3,3 ml.

Explanation:

Meperidine is a narcotic analgesic, with effect on the nervous system. It is used for moderate to severe pain control.

First, have to make the conversion of the child's weight, from lb to kg, knowing that the equivalence is 1 lb = 0.454 kg

1 lb ----------------- 0.454 Kg 66 lb ------------- X X = 66 x 0.454 X = 29.964 ≈ 30 Kg

Child's weight is 30 Kg.

The exact dose that the child should receive should be determined, according to his weight:

Dose = 1.1 mg x Kg Dose = 1.1 mg x 30 Kg Dose = 33 mg

Taking into account that there is 50 mg of meperidine in 5 ml of oral solution:

50 mg --------------- 5 cc 33 mg --------------- X X = (33 x 5) / 50 X = 3.3 cc

The volume of meperidine to be diluted in 120 cc of water per dose is 3.3 ml.

Physical fitness has many benefits, which we learned about in the unit. Can you think of any disadvantages or negative consequences to working on your physical fitness? List and briefly explain two possible negative side effects that could happen when you're being physically active.

Answers

Answer:

Possible negative side effects: muscle cramps/twitching, allergies, upset stomach, itchy skin, runny nose, etc

Explanation:

Physical exercise enhances the resistance, the functioning of the brain, enhances the heart function, regulates sleep and slows down aging. However, there are situations where an increase in physical activity has been associated with different symptoms/side effects such as, for example, muscle twitching and nasal stuffiness. Muscle twitching is caused by muscle exhaustion and an imbalance of electrolytes. Muscle twitching is a problem that can be solved by drinking cool water during training sessions in order to replenish electrolytes. Moreover, nasal stuffiness may be caused by the inflammation of the blood vessels in the sinuses, and this problem often is solved by training in air-conditioned gyms. These negative side effects and those cited above should take into consideration at the moment of making physical activities and consequently they should be consulted with the doctor at the right time.

Now, technology is changing the way that people receive and react to news stories. News has become a community affair, instead of a job in the hands of the powerful news editors. Through the Internet, people can search for opinionated or unbiased news on just about every topic under the sun. Today, the powerful are not the news editors but the news bloggers. A Web log, or blog, is a space for a person to write down his or her ideas, thoughts, feelings, or even news. Many people in the U.S. have personal blogs, in which they share parts of their lives with total strangers around the world. Now, blogs are becoming increasingly important in the world of news. Reporters caught in the thick of battle can immediately post their thoughts and feelings on blogs. Amateur writers can become instant celebrities from their focus on a particular news-worthy subject. So what are these blogs doing to news? Simply put, they are personalizing news. Blogs are making it easier and faster for readers and Internet surfers to get a behind-the-scenes look at a story. Blogs are also making it easier for people to start conversations about news events, whether that is through comments made about a particular entry or a message board attached to the blog. The Internet in general has allowed people the opportunity to really bring news into their lives. Blogs are just one more way for people to connect to a news story. Unfortunately, blogs have their problems. If they are not attached to a well-known news Web site, like Reuters, CNN, or even your local paper, the blogs are often not fact-checked. Blogs are often more about a person's opinion about an event or a personal attachment to an event or story. They are less about the straight facts and more about the personal element of the story. People have to be very careful when reading blogs not attached to familiar news companies. The right blog can be an enjoyable and personal way to experience news and understand what is going on in the world. From a reporter on the campaign trail to a family living in Iraq, readers can find out many different views on a wide variety of stories. Blogs are just one more way for people to personalize and identify with news they might not otherwise see or hear about. Take a few minutes to find a blog that fits your interests.
