Answer:
The missing options are:
a. "It's due to insufficient production of vitamin B12 in the colon."
b. "Increased production of intrinsic factor in the stomach leads to this type of anemia."
c. "Overproduction of vitamin B12 in the large intestine can result in pernicious anemia."
d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."
The correct answer is d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."
Explanation:
Intrinsic factor is a protein that is produced by cells in the stomach, this protein is essential for the absorption of vitamin B12 in the small intestine. Without intrinsic factor, the absorption of vitamin B12 would be really low, causing pernicious anemia since vitamin B12 is necessary for the production of healthy red blood cells. If there is not a good production of healthy red blood cells that can distribute O₂ and CO₂, the body suffers from pernicious anemia.
Explanation:
a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. <em>The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles. </em>
b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. <em>Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli. </em>
c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing.<em> Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.</em>
I hope you find this information useful and interesting! good luck!
Answer:
The lungs are not equal in size. The right lung is shorter, because the liver sits high, tucked under the rib cage, but it is broader/wider than the left. Each lung is separated into lobes branching off the main bronchus the right lung has three lobes, while the left has only two lobes. That's why the left lung and the right lung are difference.
Explanation:
I hope this helps. Or more in fact that this is the right answer. Let me know if is isn't. And if you need anymore help. Thank you have a good day.
All the above.
The person shows an obvious sign of life, another trained responder or EMS personnel take over and you are too exhausted to continue.
<h3>What is CPR?</h3>
- When someone's breathing or heartbeat have stopped due to an emergency, such as a heart attack or a near-drowning, cardiopulmonary resuscitation (CPR) can help save their life.
- The American Heart Association advises performing quick, forceful chest compressions to begin CPR.
- In an emergency, cardiopulmonary resuscitation (CPR) can help save a person's life if their breathing or heart stops.
- A person is in cardiac arrest when their heart stops beating.
- The heart is unable to pump blood to the rest of the body during cardiac arrest, including the brain and lungs.
- The acronym "CAB" makes it simple to remember the three essential components of CPR: compressions, airway, and breathing.
- "C" stands for compressions. Compressing your chest can improve blood flow to your heart, brain, and other organs.
- Before giving two rescue breaths during CPR, 30 chest compressions are given.
