Answer:
The correct answer would be that so drugs can act directly on targeted organs through the bloodstream or in the muscle of a particular organ.
Explanation
Certain drugs are administered by injection because they can not be taken oral mode as the entire dose of the drug is destroyed in the liver before reaching the circulation. Injections are suspension or liquid, injected into a vein, organ, or tissue as per the requirement or the best place to get it in circulating.
The mode of administration of injection can be intradermal, intramuscular, in some cases intracardiac or brain intracerebral so the drug can directly reach to targeted organ or indirect circulation.
Thus, the correct answer is that so drugs can act directly on targeted organs through the bloodstream or in the muscle of particular organs.
Answer:
True
Explanation:
the K+ channel filters selects K+ ions more than Na+ ions because K+ ions can go through the filter along with water ions within nano seconds, whereas, Na+ ions bound to the sites within the filter and does not move within the channel in a nano second time scale. This rapid transport gradient of hydrated K+ ions makes it selectively permeable. Moreover, K+ ions has the capacity to accommodate itself around eight oxygen atoms in the central cavity but the Na+ ions interacts with four oxygen atoms and two water molecules instantly making significant ion-protein interactions. A dehydrated Na+ ion stabilizes itself with oxygen and decreases its chances of reaching the central cavity of K+ channel.
Answer:
The answer to the question: Name the phase when the atrioventricular valves and the semilunar valves are all closed during ventricular diastole, would be: the isovolumic, or isovolumetric relaxation.
Explanation:
The systolic and diastolic cycles of the heart ensure that blood is always being circulated around the body from the heart, and from the body to the heart. While systole implies the moments of contraction and active motion of the heart muscles to ensure the correct passage of blood from the four chambers of the heart (atria and ventricles), to and from the body, diastole is the time when either the atria, or ventricles relax to allow the flow of blood into them. To also ensure this process is seamless, there are a series of valves, the atrioventricular valves, or AV valves, and the aortic and pulmonary (semilunar) valves, that will ensure that blood can flow from the atria to the ventricles (AV valves) without flowing back, and that blood will flow towards the body through the aorta, and the lungs, through the pulmonary arteries, through the aortic and semilunar valves, without going back into the ventricles. At one point, when the ventricular diastole begins, there is an early stage known as the isovolumic, or isovolumetric stage, meaning, volumes are pressures are equalized and then both the AV valves and aortic and pulmonary valves are closed only for a bit as the ventricles relax. Not soon later, the AV valves will start opening to allow the gentle flow of blood from the atria, to the ventricles, before actively initiating atrial systole.
Answer:
Well, doctors choose solutions with specific sales variables or minerals essential for hydration, which is why it is also called "saline" in many places. Which the sales characteristics are ideal for there to be no dehydration or overhydration in the human body.
If an uncontrolled hyperosmolar solution is injected intravenously, the patient could enter severe dehydration, since the cells through the osmosis process seek to balance the proteins and release water into the medium, losing intracellular fluid, dehydration, drying.
Explanation:
In our organism a spontaneous process occurs called osmosis, which needs if or if two different components, with different concentrations, and a semi-permeable membrane where only the water can permeate to be able to match the osmolar concentrations of the different solutions that are in different compartments.
The water will always diffuse from the zone of less concentration to one of greater concentration, since the solutes attract aqueous masses.
This chemical explanation happens in the body, that is why it is very important to understand it, because if we inject hyperosmolar solutions such as piped water or other solutions in patients who need to maintain their normal blood volume, they could lead to death.
The organism is in constant hydrodynamic and saline balance, that is why with solutions such as physiological serum we maintain that balance
