If the arteries were lifted from the base of the pulmonary trunk, they would only have access to deoxygenated blood, which is not what the coronary artery is designed to do.
What is the main role of coronary artery in heart?The coronary arteries supply blood to the heart muscle. The heart muscle needs oxygen-rich blood to function, just like every other part of the body does.
Blood that lacks oxygen must also be transported away. Outside the heart, the coronary arteries encircle the organ.
The three coronary arteries of the heart are not all created equal. The left anterior descending artery is the most significant artery (LAD).
It supplies blood to the entire front wall of the heart, which contains a lot more muscle than either of the two major coronary arteries combined.
Therefore, it is false that carotid artery is the best place to check your pulse because it is the closest to your heart.

Answer: True
Explanation:
bird is the word
1List three central limitations to aerobic capacity (VO2max) 3 points
2List two peripheral limitations to aerobic capacity (VO2max) 2 points
3Do Kravitz and Dalleck believe that central or peripheral limitations limit VO2max? 1 point
4What is the lactate threshold? 1 point
5Define exercise economy
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 flow2. 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 density3. 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.
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.

A nurse reported a patient's height as 62". Why might this be
confusing in the U.S.?
A. It's not confusing because the nurse expressed the
measurement in the most common unit expected in
the U.S.
B. Height is typically spelled out, not measured as a
numerical value.
C. This measurement is not expressed in the most
common unit expected in the U.S.
D. The nurse should have used the unit pounds to
measure the patient's height.
Answer: C
Explanation:
This measurement is not expressed in the most common unit expected in the U.S.
What is Height?Height is a measurement of vertical distance, or how high something or someone is (how tall they are) (how "high" a point is). For instance, "That building is 50 meters high," or "An airplane flies around 10,000 meters high." Christopher Columbus, for instance, has a height of 5 feet 2 inches.
Height is more frequently referred to as altitude when describing the vertical position (of, for example, an airplane) from sea level. Furthermore, elevation (height above sea level) is known as altitude if the point is connected to the Earth (for example, a mountain peak).
Height is calculated between two points in a two-dimensional Cartesian space along the vertical axis (y) that do not share the same location.
Therefore, This measurement is not expressed in the most common unit expected in the U.S.

your gender height weight and age are the different attributes that make up your _______ 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.

For individuals with or at risk for coronary heart disease, data suggest that more than ____ calories per week may have to be expended to improve cardiorespiratory fitness.
Answer:
The correct answer is: 1400.
Explanation:
Coronary heart disease is a condition that occurs when there's a decrease in the amount of blood flow to the heart because of the buildup of atheromatous plaque in the coronary arteries, which provide blood to the muscle of the heart. This plaque is made of cholesterol and fat, so diet plays a big role in the development of this life-threatening disease. Smoking, obesity, diabetes, high blood pressure and a family history of coronary heart disease are important risk factors as well.
Coronary heart disease will eventually lead to heart failure and possibly death, so it needs to be treated as soon as it's diagnosed. There is no cure for this disease, but a change in one's lifestyle and a combination of medication can extend the life expectancy of the person who suffers from it.
The changes in lifestyle that are recommended to treat Coronary heart disease are: exercise, like walking or swimming, smoking cessation, weight control, and a healthier diet with minimal to none trans fats ingestion. Doctors recommend their patients with this condition a lower calorie intake, of about 1400 calories less per week.
