When the ventricular myocardium receives an electrical impulse, it stimulates a
contraction that:
only pulls in deoxygenated blood from the body.
O pushes both types of blood to both the lungs and body.
only pushes deoxygenated blood to the lungs.
only pulls in oxygenated blood from the lungs.

Answers

Answer 1

Answer:

pushes both types of blood to both the lungs and body.

Explanation:

These fibers transmit the electrical impulse to the myocardium (cardiac muscle). The myofibers in the ventricular myocardium contract at the same time because the impulses are transmitted rapidly. When the ventricles contract, the blood from both ventricles is forced out through the pulmonic and aortic valves into the pulmonary and systemic circulation.

Answer 2

The electrical shock causes the heart's ventricles to contract and pump blood as it moves along the conduction channels, hence option B is correct.

What is ventricular myocardium?

Before the two lower chambers of the heart may contract, the two upper chambers of the heart (atria) are activated first (ventricles).

Cardiomyocytes and fibroblasts make up the majority of the cells in the myocardium. Along with the extracellular matrix (ECM), blood arteries, lymphatic vessels, and nerve terminals, fibroblasts are dispersed throughout cardiomyocytes.

A thin layer of connective tissue connects the myocardium to the endocardium, the deepest layer of the heart wall.

Therefore, the heart valves are protected by the endocardium, which also borders the blood circulation chambers, hence option B is correct.

Tsunamis are disasters that cannot be prevented. However, after the tsunami in Indonesia in 2004, many island nations developed early warning systems to alert the people when the ocean tides were rising. This allows people to get to higher ground before the tsunami hits, decreasing the loss of life and devastation from a tsunami. This is an example of what?

A. Preparation
B. Response
C. Recovery
D. Mitigation

Answers

Answer: D. Mitigation

Explanation: What pops out to me in this question is "decreasing the loss of life and devastation from a tsunami." I thought it was A for a second but I remembered the definition of Mitigation. Mitigation means the action of reducing the severity, seriousness, or painfulness of something. This means that this was here to decrease the loss of people. If this answer so happens to be incorrect, A should be the correct answer. But here they are trying to reduce losing people therefore, D would be the correct answer.

Answer:

D.) Mitigation.

According to Maslow, physiological needs are at the base of the hierarchy of needs because...
1. physiological needs are the least important needs.
2. if physiological needs are met, an individual can skip the next level.
3. physiological needs are not the most important needs.
4. if physiological needs are not met, an individual cannot move to the next level.

Answers

Answer:

4

Explanation:

According to Maslow, physiological needs are at the base of the hierarchy of needs because if physiological needs are not met, an individual cannot move to the next level.

What is Maslow's hierarchy of needs?Physiological demands - air, food, drink, shelter, clothes, warmth, sex, and sleep are all biological necessities for human survival.Human body cannot function optimally if these demands are not met. Physiological needs are the most important, according to Maslow, because all other wants are secondary until these are addressed.

Safety needs - after a person's physiological demands are met, security and safety become more important. In their daily lives, people seek order, predictability, and control. These requirements can be met by the family and society (e.g. police, schools, business and medical care).

After physiological and safety requirements are met, the third level of human wants is social, which includes feelings of belonging.

Self-worth, accomplishment, and respect are among the fourth level of Maslow's hierarchy of needs. Maslow divided esteem needs into two categories: self-esteem (dignity, achievement, mastery, independence) and esteem for others (reputation or respect) (e.g., status, prestige).

Maslow's hierarchy's highest level, self-actualization needs, allude to a person's realization of potential, self-fulfillment, personal growth, and peak experiences. This level is defined by Maslow (1943) as the drive to achieve everything one can, to become the best one can be.

Answer:

Its true

Explanation:

Just took the test

A neutral stimulus cause no response but when combined with an unconditioned stimulus, induce learning, hence statement is true.

What is a neutral stimulus?

A neutral stimulus doesn't really initially elicit a specific response, but when combined with an unconditioned stimulus, it can effectively induce learning, eventually becoming a conditioned stimulus.

Yet, ringing a bell doesn't quite elicit the same response. As a result, the sound of a bell is a neutral stimulus. When paired with an unconditioned stimulus, a neutral stimulus becomes a conditioned stimulus.

After repeated exposures both to the neutral stimulus and the unconditioned stimulus, the neutral stimulus will begin to elicit a conditioned response.

Therefore combined with an unconditioned stimulus, can induce learning, hence neutral stimulus causes no response is a true statement.
