What is in control of "twisting" the ventricular walls in order to squeeze out all the blood into the aorta or pulmonary trunk? Group of answer choices purkinje fibers AV nodes SA nodes pacemaker cells

Answers

Answer 1

Answer:

The correct answer is:

Purkinje fibers

Explanation:

The human heart is an organ, made up majorly of muscles called cardiac muscles, and is responsible for pumping blood throughout the body. The cycle of coordination of blood flow through the heart is known as the cardiac cycle and the process is coordinated by the cardiac conduction system.

The process starts with the sinoatrial (SA) node, also known as pacemakers, causing the generation of impulses that travel through the heart causing the contraction of the atrium (upper part of the heart). This impulse moves to the AV bundle (bundle of His), which branches out, spreading into enlarged fibers called Purkinje fibers. When the impulses reach the Purkinje fibers, it generates the contraction of the ventricular walls in a twisting motion, forcing blood into the aorta.

5 Factors that Influence What Teenagers Eat and How Teenagers Eat

Answers

Answer:

Factors perceived as influencing food choices included hunger and food cravings, appeal of food, time considerations of adolescents and parents, convenience of food, food availability, parental influence on eating behaviors (including the culture or religion of the family), benefits of foods (including health), situation-specific factors, mood, body image, habit, cost, media, and vegetarian beliefs. Major barriers to eating more fruits, vegetables, and dairy products and eating fewer high-fat foods included a lack of sense of urgency about personal health in relation to other concerns, and taste preferences for other foods. Suggestions for helping adolescents eat a more healthful diet include making healthful food taste and look better, limiting the availability of unhealthful options, making healthful food more available and convenient, teaching children good eating habits at an early age, and changing social norms to make it "cool" to eat healthfully.

Which issue are teen parents more likely to experience than adult parents?
low-paying jobs
loss of friendships
constant responsibility
limited childcare availability

Answers

The issue that teen parents are more likely to experience than adult parents is low-paying jobs.

Being a teen parent means that the individuals involved began raising a child in an inappropriate time.

A teenage is considered to be from the age of 13 to 19.

Under the educational system, this age range (teenagers) should still be in high school and therefore not yet ready for the labor market.

Because of the present responsibility the teenage parent is involved with, such is forced to drop out from school and take up low paying jobs.

Low paying jobs are those jobs that pay less than two-thirds of the median or mean of gross hourly wages.

Because these teenage parents are School dropouts and faced with family responsibilities, they are susceptible to low-paying jobs

Some examples of low paying jobs include:

Laundry and dry-cleaning workersHosts and HostessesCooks.

Answers

Answer:

you find your happy place or do somthing that makes u happy

..I hate this topic, but, it's a hard thing to go through, just don't be an idiot and start cutting. From past experience, I'd say that sometimes you have to accept it, cause it's your only friend.. But letting it go can take some time, you got to accept your self, accept the world and accept the bad things and the good things. Sometimes you just wanna crawl into a ball and cry your heart out, or you just wanna do the most unacceptable things in life.. Just know someone out there loves and cares about you. And if you were gone, you would be passing the depression down to that person.. and it would keep getting passed down.

Most importantly give someone a hug, or Think About What Went Well Allow Yourself To Vent. I promise you it will get better!
