In ventricular fibrillation, the ventricles twitch randomly instead of beating. This condition causes death within minutes if not rapidly treated. In a similar condition, atrial fibrillation, atria twitch randomly instead of beating. Although atrial fibrillation can increase the risk of other serious conditions, atrial fibrillation by itself is usually not life threatening. Explain why ventricle fibrillation is deadly but trail fibrillation rarely is. Include a description of blood flow through the heart.

Answers

Answer 1

Answer:

Ventricular fibrillation a type of arrhythmia characterized by a very fast heart rate which causes no blood to reach vital organs causing cardiac arrest.While Atrial fibrillation is an atrial tachyarrhythmia characterized by the fact that the atria beat in an uncoordinated way at a very high rate that exceeds 350 beats per minute. As a result, the atria are no longer effective in pumping blood to the ventricles.

Explanation:

Under normal conditions the heart contracts rhythmically and synchronously. This contraction is the result of an electrical impulse that is generated in the atrium, reaches the ventricle and results in a heartbeat. In an arrhythmia there is an alteration of this mechanism that leads to the heart not contracting regularly, generating a rhythm disorder. The contraction of the ventricles pumps blood to the rest of the body. In ventricular fibrillation, the heart rhythm is very fast and chaotic (up to 300 beats per minute) and is characterized by not being able to provoke an efficient heart beat. Thus, the lack of contraction of the ventricles causes the blood to barely be pumped from the heart, producing a collapse of the cardiovascular system and cardiac arrest. Atrial fibrillation is characterized by disorganized and very rapid atrial activity (350-600 beats / min). This leads to an irregular ventricular response (150-200 beats / min) and an irregular pulse.During atrial fibrillation, the atrial contraction that helps fill the ventricles with blood is lost; this can significantly reduce cardiac output, particularly in patients with mitral stenosis, hypertension, or hypertrophic cardiomyopathy.It is associated with an increased risk of thromboembolism (formation of blood clots in the heart that can dislodge and go through the bloodstream until impacted on the a blood vessel, causing lack of irrigation in that area) and therefore stroke (cerebral thromboembolic accident).

How does agriculture affect your daily life? List 3 items that are CRUCIAL to your daily life and where they come from

Answers

Answer:

This may help. I got this answer from "5 ways agriculture impacts our daily lives" These were just the top 3. :)

Explanation:

1. Family

Even if you don’t own a farm or any livestock, agriculture still impacts your family. Think about how you feed your family. Where does that food come from? It doesn’t just magically appear in the grocery store! Now think about how you clothe your family. Many clothes get made with wool, cotton, and other materials that farmers and ranchers produce. If it wasn’t for agriculture, it would be harder to provide for your family.

2. Economy

According to the United States Department of Agriculture, the ag, food, and related industries contributed over $1 trillion to the country’s gross domestic product (GDP). This industry also provides over 22 million full and part-time jobs. Also, when the ag sector is able to meet the supply and demand for food and other products, it helps to keep prices down for the consumer.

3. Health

Alfalfa is a common crop grown in North America. Because alfalfa is rich in minerals and nutrients, this plant is often fed to livestock. For humans, alfalfa can help treat morning sickness, nausea, and kidney stones. Not all farmers raise traditional crops, however. Some of them grow plants that are used for medicinal purposes. These plants include plantain, yarrow, elder, sage, and common mallow. Farmers also grow fruits and vegetables, which play a key role in healthy diets.

I NEED HELP ASAP PLEASE ;-;

Answers

Answer:

The five different careers in Health Science that I would like to purse are nurse practioner, nutritionist, radiology technologist, physicians assistant and emergency medical technician. The three that appeal most to me is the nurse practioner, radiology technologist, and emercengy medical technician. The career choice and educational pathway that appeals to me the most is radiology technologist.

A radiology technologist is responsible for taking a picture of the patients x-ray, examining it and treating it. As a radiologic technologist I would need to check to make sure all the equipment is operational before taking any images. They work in anatomy and use many different equipment such as x-rays, MRI, computed tomography, etc. Sometimes before creating the image I would need to prepare and inject radiopharmaceutical agents into patients. Also, I may help physicians perform procedures such as angioplasty or stent insertion. I like this career because I am intereseted in learning about the human body and I want to help patients.

The colleges or universities that have the program to become a radiology technologist are Long Island University, University of Wisconsin La Crosse and Manhattan College. In order to purse this career I would need a associate's and bachelor's degree which takes about four years. Also, it would be a good idea to go training and attend certificate programs for radiology techs that take around a year. The best credentials are combinations of formal training, a professional license and work experience.
