Describe two ways blood is helped back to the heart in veins. mention relevant body systems.

Answers

Answer 1
Final answer:

Blood is assisted back to the heart in veins through valves preventing backflow and the skeletal muscle pump. Pressure changes from breathing (respiratory pump) and vascular tone also contribute.

Explanation:

How Blood is Helped Back to the Heart in Veins

One way that blood is helped back to the heart in veins is through the presence of valves that prevent backflow of blood. This ensures that blood only moves in one direction, towards the heart. A second important mechanism is the skeletal muscle pump, where the contraction of muscles during body movements compresses the veins, acting like a pump to push blood towards the heart.

Another significant assistive factor is the respiratory pump, which utilizes the pressure changes in the thoracic and abdominal cavities during breathing to help pull and push blood back to the heart. Venous pressure is also facilitated by the maintenance of vascular tone, where constriction of venous walls helps to move blood more effectively.

Why did Jefferson launch the Lewis and Clark expedition? to explore territory that the United States could purchase to explore areas in the northern United States and Canada to explore the vast Louisiana Territory to make peace with Native Americans

Answers

to explore the vast louisiana territory, because the louisiana purchase just happened so he wants to explore the new land

Answer:

To explore the vast louisiana territory.

Explanation:

In 1800 Thomas Jefferson became the third president of the United States, at that time the nation occupied an area of ​​approximately 1600 kilometers from the coast of the Atlantic Ocean to the Mississippi River on the west side and the Great Lakes to the north to the Gulf of Mexico to the south.

The roads were very bad at this time, the rivers, therefore, were the favorite routes to trade. In 1803 Jefferson doubled the size of the United States by buying Louisiana from the French for the price of $ 15 million. The United States now had access to the port of New Orleans and the Wild West, beyond the Mississippi.

Thomas Jefferson assigned the exploration of these new lands to Meriwether Lewis, his personal secretary since 1801. His goal was to find a river path that connected east and west. Lewis showed his genius by choosing his friend William Clark for his fantastic adventure. Clark was four years older than Lewis, who was an introvert dreamer and intellectual, while Clark was the opposite: a strong, pragmatic man with a lot of judgment.

Which is not a result of hypertension?

A. The liver excretes excess cholesterol in bile.
B. Blood vessel walls are damaged by the increased force of blood.
C. The heart works harder to pump blood through the body.
D. The heart weakens and eventually fails to pump blood adequately.

Answers

The answer is A..the other answers have something in common about blood vessels being damaged and the heart working harder and getting weaker..I personally was on cholesterol medicine and my blood pressure was normal without medication..high blood pressure does make the heart work harder which is why your heart rate is usually high along with it, and it does eventually weaken the heart due to damaging the walls of the blood vessels which causes inadequate blood flow

A, because the liver doesn't excrete excess cholesterol in bile as a result of hypertension.

What causes oppositional defiant disorder and disruptive mood dysregulation disorder?

Answers

Hormone imbalances, neurotransmitter imbalances, etc. that’s what certain medications are designed to target and correct. Most of the rest is media drama.
Hope that was the answer you needed.

Oppositional Defiant Disorder (ODD) and Disruptive Mood Dysregulation Disorder (DMDD) are caused by genetic, environmental, and psychological factors. Effective treatments often include learning-based interventions and cognitive-behavioral therapy. Both disorders involve issues with emotional regulation and behavior management.

Oppositional Defiant Disorder (ODD) and Disruptive Mood Dysregulation Disorder (DMDD) are complex psychological conditions that affect children and adolescents. The causes of ODD can include a combination of genetic, environmental, and psychological factors. Individual genetics may predispose a child to ODD, while environmental factors like inconsistent discipline, lack of supervision, and exposure to violence can exacerbate the condition. Additionally, psychological contributions such as a child's temperament and difficulty processing emotions play a critical role.

DMDD is primarily characterized by severe temper outbursts and persistent irritability and is thought to stem from both biological differences in brain function and environmental stressors. Brain imaging studies suggest that children with DMDD may have anomalies in brain areas related to emotion regulation, including the amygdala and prefrontal cortex. Furthermore, stressful home environments, exposure to trauma, and a history of other mental health disorders can increase the likelihood of DMDD development.

Learning-based interventions, such as parent management training and problem-solving skills training, have been shown as effective treatments for ODD. In DMDD, cognitive-behavioral therapy and medication are often used to help manage symptoms and improve emotional regulation.

Discuss which of the four phases in the food chain you think is the most important part of the chain. Explain why you believe this is true using at least 2 complete, detailed sentences.

Answers

Answer:

The most important thought of the food chain would be manufacturing and processing

Explanation:

because they pack the food and take safety measures and they identify ways to control, identify and minimize or prevent food safety hazards that could make us sick.

Final answer:

The most crucial phase of the food chain might be primary producers who convert solar energy into usable chemical energy or decomposers who recycle nutrients, both underpinning the ecosystem's health.

Explanation:

A food chain is a linear sequence of organisms through which nutrients and energy pass, involving multiple trophic levels such as primary producers, primary consumers, and higher-level consumers.

The most important part of the food chain can be debated, but many would argue that primary producers are essential as they are the base of the food chain, converting solar energy into chemical energy through photosynthesis which sustains the entire ecosystem. However, others might highlight the importance of decomposers as they recycle nutrients back into the ecosystem, maintaining the health of the soil which in turn supports the primary producers.

?a person that develops asthma after living in a city with severe air pollution for decades is experiencing a(n ____.

Answers

Developing asthma after living in a city that has severe air pollution for decades is an example of experiencing a chronic effect.
Final answer:

A person developing asthma after living in a city with high pollution is experiencing an environmentally-induced chronic disease. Long-term exposure to pollutants and allergens may cause individuals to develop asthma, a respiratory disorder that involves inflammation and narrowing of the airways. Emotional stress can also exacerbate these conditions.

Explanation:

A person that develops asthma after living in a city with severe air pollution for decades is experiencing a type of environmental onset illness. Asthma is a chronic disease in which the airways become inflamed, leading to difficulty in breathing. It's often triggered by environmental factors such as air pollution.

Areas with high rates of air pollution, like certain cities, can increase the risk of developing asthma or exacerbate existing conditions. Various environmental pollutants like smoke, dust, and allergens have been known to induce asthma attacks - acute episodes that may include wheezing, chest tightness, shortness of breath, and coughing.

Interestingly, stressful experiences and negative emotions, such as high levels of stress, can also trigger symptoms of asthma. Thus, maintaining a balanced, stress-managed lifestyle may ameliorate some of these symptoms. Research has also shown that asthma and related diseases are more common among lower-income communities where high pollution and air quality are common issues.

Answer:

C. 100 cc

Explanation:

The choices for this answer are

A. 90cc

B. 120cc

C. 100cc

D. 50cc

We just need to subtract to find the answer.

Remember that the intake is the difference between the total amount of cc and the number of cc that remains.

So, if there's 50cc left in the glass, and its capacity is 150cc, that just means your intake was 100cc, because
