Answer:
Portal circulation is delimited between two large capillary beds at their ends, at one end we find the capillaries of the gastrointestinal organs, pancreas and spleen, and at the other end, the capillary beds of the liver.
Answer:
The most likely cause of the hearing change is a long exposure to high-frequency noise during a 4-hour flight.
Explanation:
The most common high-frequency sensorineural hearing loss is normally caused by noise exposure or aging, and often both. In this condition loud noises like a plane taking off or explosion damage the hair cells at the base of the cochlea.
The man experiencing tinnitus and hearing loss after the four-hour flight and as per the audiogram demonstration, the cause of the hearing change is most likely due to the exposure of the high-frequency sound or noise.
Thus, the correct answer is a long exposure to high-frequency noise during a 4-hour flight.
Increasing extracellular K+ increases the positive charge outside the cell, making the inside of the cell (membrane potential) more negative. This inhibits net diffusion of Na+ into or out of the cell.
Explanation:
- <em>Presynaptic mechanism:</em> one way to modify the synaptic transmission before it happens is affecting transmitters release, one example is calcium channel blockers (for example, verapamil), this action won't allow transmitters out, therefore, there won't be a synaptic transmission.
- <em>Postsynaptic mechanism:</em> one method to modify synaptic transmission after it happens is blocking the transmitter receptors, one example of this is antipsychotic drugs that block dopamine receptors.
I added some images with another examples for both cases. I hope you find this information interesting! Good luck!
The explanation which the nurse would provide when responding to a clients inquiry about intussusception of the bowel is telescoping of a proximal loop of bowel into a distal loop.
<h3>What is Intussusception?</h3>
This is referred to as a medical condition which is characterized by parts of the intestine obstructing or telescoping each other and can be caused by different factors such as tumor, inflammation etc.
This type of process includes the telescoping of a proximal loop of bowel into a distal loop and can be treated with the aid of surgeries to correct the situation by trained professionals.
