Surfactant in the lungs helps to increase
O a. expiration
b.rales
c. expansion of the lungs
d. orthopnea
e. exhalation

Help please

Answers

Answer 1

Answer:

Surfactant in the lungs helps to increase expansion of the lungs

Explanation:

Pulmonary surfactant is a substance composed mainly of proteins and lipids, which acts as a surface active agent, preventing the pulmonary alveoli from collapsing or closing.

The pulmonary alveoli are responsible for carrying out the gaseous exchange, passing oxygen into the blood and receiving the carbon dioxide that they must eliminate. Pulmonary surfactant —secreted by type II pneumocytes— decreases the surface tension of the alveolar liquid, preventing its closure and facilitating its expansion.

The other options are not correct because:

    a. Expiration is one of the components of the respiratory cycle, and is not related to the surfactant.

    b. Rales (crackles) are abnormal breathing sounds, due to the presence of fluid in the alveoli.

    d. Orthopnea is the sitting position that a person adopts when he or she has severe breathing difficulty, preventing him or her from lying down.

    e. Exhalation = expiration.

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

Answers

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.

WNV-specific IgM antibodies are usually detectable 3 to 8 days after onset of illness and persist for 30 to 90 days, but longer persistence has been documented. Therefore, positive IgM antibodies occasionally may reflect a past infection. If serum is collected within 8 days of illness onset, the absence of detectable virus-specific IgM does not rule out the diagnosis of WNV infection, and the test may need to be repeated on a later sample.

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.

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.

A meter is the basic unit for measuring what?
A. Volume
B. Weight and mass
C. Length and distance
D. Time

Answers

Answer:

C

Explanation:

A meter measures distance. We don't say the cube is x meters long, just as we don't say we weigh x amount. Instead we use units like centimeters for volume while we use pounds or kilograms for weight. In terms of time, I have no idea how the unit meters would be useful for that. Example for time units include: seconds, minutes, hours, and days. However, we do say this ruler is x amount of meters. As such, length and distance is the only logical answer.

C. Length and Distance

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.

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.

Answers

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.

Good stress is called Eustress, Bad stress is called Distress and the process of achieving balance iscalled the fight or flight response?
True or False

Answers

Answer:

False

Explanation:

Fight or flight response isn't the process of achieving balance. Allostasis is the correct name for that process.

Good stress is called Eustress, Bad stress is called Distress and the process of achieving balance is called the fight or flight response is a true statement.

What is stress ?

Stress is a normal response to difficult, upsetting, or frightening internal and external circumstances. Anxious feelings, physical sensations like pain or discomfort, and troubling thoughts or memories are examples of internal stressors. Anything troubling that has the potential to have a negative impact on someone or something they care about is considered an external stressor.A type of positive, beneficial, and motivating stress known as eustress is a relatively new concept. Unlike distress, eustress inspires people to work hard, perform better, and achieve their goals despite obstacles. Both eustress and distress involve the brain and body activating the fight or flight response.The negative kind of stress that most people associate with feeling "stressed out" is referred to as distress. Overwhelm, anxiety, and physical and mental symptoms like headaches, tension, insomnia, inattention, and irritability are all common manifestations of stress. In addition to impairing a person's ability to function, frequent, intense, or chronic stress is toxic to the body and brain, linked to a number of physical and mental illnesses.An automatic physiological response to an event that is perceived as stressful or frightening is known as the fight or flight response. The body's acute stress response and sympathetic nervous system are triggered by threat perception, preparing it to fight or flee.

Which statement describes the movement of water when a cell swells up and bursts due to osmosis?

Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.
Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.
The cell membrane used energy to move water into the cell through passive transport.
The cell membrane used energy to move water out of the cell through passive transport.

Answers

Answer:

Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.

Explanation:

Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.  - this is true. Water moves from a high concentration to a low concentration (outside the cell to inside the cell) via osmosis. This can cause the cell to swell and burst.

Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.  - this is false, water moves from a high concentration to a low concentration

The cell membrane used energy to move water into the cell through passive transport.  - this is false, passive transport does not use energy

The cell membrane used energy to move water out of the cell through passive transport. - this is false, passive transport does not use energy and water moved into the cell
