Explain how blood is pumped through the heart in complete sentences

Answers

Answer 1

Answer:

Explanation:

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart.

As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.

• As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated. Note that oxygen-poor or CO2 containing blood goes through the pulmonary artery to the lungs where CO2 is exchanged for O2.

Left side of the heart (operating at the same time as the right side of the heart)

The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium of the heart.

As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.

When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.

As the ventricle contracts, oxygen-enriched blood leaves the heart through the aortic valve, into the aorta and to the arteries and eventually into veins to complete the blood circulation in your body.

Answer 2

The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

Which of the following pairs of directional terms is incorrect?

1)superficial and lateral
2)superior and inferior
3)anterior and posterior
4)cranial and caudal

Answers

Answer:

The pair of directional terms that is incorrect is superficial and lateral.

Explanation:

Directional terms are commonly used in biology and anatomy and indicate the position of body structures with respect to others or in relation to the body. These terms are usually paired with their opposite, which translates into the same or opposite position.

An example of directional terms are ipsilateral and contralateral, to indicate when ods structures are on the same side or on opposite sides.

In the case presented, superficial and lateral are two terms that are not opposed, since the opposite of superficial is deep and the lateral is medial.

Regarding other options:

Superior and inferior , anterior and posterior , cranial and caudal are directional terms paired by an opposition relationship.

What are the Pros and Cons of completely legalizing marijuana
(for a essay)

Answers

Pro

Marijuana legalization boosts the economy.

The marijuana industry (adult-use and medical) in the United States could exceed $24 billion in revenue by 2025. [7] For every $1.00 spent in the marijuana industry, between $2.13 and $2.40 in economic activity is generated. [1][2] Tourism, banking, food, real estate, construction, and transportation are a few of the industries that benefit from legal marijuana. [3]

The legal marijuana industry generated $7.2 billion in economic activity in 2016, and added millions of dollars in federal taxes paid by cannabis businesses. [20] One study on adult-use marijuana in Nevada projected $7.5 billion in economic activity over the first seven years of legalization, including $1.7 billion in labor income. [4] A study by the University of California Agricultural Issues Center estimated that the legal marijuana market in California could generate $5 billion annually.

In Colorado, marijuana brings in three times more tax revenue than alcohol. The state raised $78 million in the first fiscal year after starting retail sales, and $129 million the second fiscal year. Washington collected a total of $220 million in tax revenues in its second fiscal year of sales.

Con

Legalized marijuana creates steep costs for society and taxpayers that far outweigh its tax revenues.

Marijuana use harms more than just the person using the drug. [129] Societal costs of marijuana use include paying for increased emergency room visits, medical care, and addiction treatment for the uninsured; more victims of drugged driving accidents; increased crime; and a negative impact on health from secondhand smoke. [78][102]

Annual societal costs from alcohol ($223.5 billion) and tobacco ($193 billion) far exceed the $24 billion in tax revenues they raise. [128][128][131][172] Money raised from legal marijuana taxes generally accounts for less than 1% of a state’s tax revenue. [132][134]

Legalizing marijuana would put one more harmful substance in our society that costs more than the revenue it generates. [130] According to the Pew Research Center, “the most frequently mentioned reason why people oppose legalization is that marijuana generally hurts society.”
