Consider the model of temperature regulation in humans. Instead of an increase in temperature, as seen here, imagine that the hu

man bod temperature drops. Explain how this model would most likely change in response to a drop in temperature? A) Signals from the hypothalamus would stop B) The blood vessels move up and down in the skin C) Vasodilation would be replaced by vasoconstriction D) The vasodilation step in the model would include shivering

Answer: C) Vasodilation would be replaced by vasoconstriction

Explanation:

The blood vessels supplies blood to the skin can dilate this is called as vasodilation process. This process allows the transfer of more amount of heat from the blood to the skin where the heat can be lost through the air. The blood vessels can shrink again this is called as vasoconstriction. This process will prevent the loss of heat from the skin and the temperature of the body will be returned to the normal.  

If the human blood temperature drops vasodilation process will be prevented as more loss of heat can lead to excess cooling of the body for example frostbite or even death. The frostbite is an injury which is caused due to freezing of the skin as well as the underlying tissues.

Answer:Option C

Explanation:

In case the temperature of the body goes too low and it feels chills then the vessels of the body constrict in order so that there is a less flow of blood and the skin and core body conserve the temperature of the body.

This is a negative feed back mechanism in order to maintain the temperature of the body.

There are some more responses of the body in order to maintain the temperature of body. The shivering starts, the skin and the capillaries becomes more Skinner in order to restrict the blood flow.

If all glucose is normally reabsorbed in the proximal tubule of the nephron, why do people with diabetes have glucose in their u
Svetlanka [38]

Answer:

People have glucose in their urine because they reach very high glucose values, that is, glycemic peaks.

Glycemic peaks occur due to a functional lack of the hormone insulin, insulin in this pathology is altered or absent, that is why the cells cannot assimilate energy and glucose does not enter the intracellular medium.

When glycemia reaches very high values, it is secreted by urine, but not all glucose is secreted, that is why high concentrations of glucose will be found in plasma and urine, this is called glycemia or uremia in the case of urine.

Diabetes disease is discovered by laboratory tests and clinical signs, the most frequent are: high blood glucose, glycosylated hemoglobin, uremia, high concentration of ketone bodies or ketoacidosis, ketone breath, alteration of the cardiovascular system, high cholesterol, weakness or fatigue, spontaneous diarrhea, among others.

Explanation:

The nephron is the glomerular filtration unit, in which a filtering of the body's waste takes place, through channels or diffusion waves, these channels or these diffusion mechanisms, some are non-saturable and others are saturated in the face of extreme concentrations, That is why, in the event of glycemic peaks, the nephron is highly demanded to eliminate glucose, and the mechanism of excision by urine could even be oversaturated.

People who suffer from diabetes can be for various reasons, genetic causes, obesity, ideopathic, autoimmune disorders or even due to genetic failure in the formation of the hormone insulin.

The only effective method to be able to regulate this imbalance and help the nephron to eliminate it correctly is by giving the patient injectable insulin or oral hypoglycemic agents.

Which treatment is appropriate for victims of a biological terrorism incident that has caused them to develop hemorrhagic fever?
fomenos

Put on clean clothes after washing with soap and water. Make a call to the authorities and go to the hospital. It can be suggested that you isolate yourself or stay away from other people. If your symptoms are similar to those listed and you fall into the category of those who are at risk, get emergency medical help right once.

<h3>How are bioterrorists handled?</h3>

The CDC recommends intravenous ciprofloxacin or doxycycline together with one or two other antimicrobials, as indicated above, to treat anthrax inhalation in a bioterrorism scenario. Therapy can be altered further when additional data on antibiotic susceptibility becomes available and the clinical situation permits.

Supportive care and antitoxin are included in the treatment of severe symptoms. Biochemical Discord: It's a neurotoxic. Botulinum is one of the most deadly toxins.

after administering a loop diuretic, a nurse monitors the client for increased urine output. what principle explains the seconda
Levart [38]

The correct answer for this question is Osmosis.

Osmotic diuresis is an increase in urine production brought on by the presence of specific chemicals in the tiny kidney tubes. When chemicals like glucose enter the kidney tubules and cannot be reabsorbed, excretion takes place (due to a pathological state or the normal nature of the substance). The compounds raise the osmotic pressure inside the tubule, which causes water to be retained in the lumen and inhibits water absorption, boosting urine production (i.e., diuresis). Therapeutics like mannitol, which is used to improve urine output and decrease extracellular fluid volume, have the similar effect.

By making the blood more osmolar, substances in the circulation can also increase the volume of fluid flowing through the body.
