It’s the study of diseases and disorders affecting blood cells, their production, and any organs and tissues involved in hematopoiesis such as bone marrow, the spleen and the thymus ( hope that helps you out a little )
According to the research, the correct option is Period of invasion. The stage of an infectious disease when specific signs and symptoms are seen and the pathogen is at peak activity is the Period of invasion.
<h3>What is an infectious disease?</h3>
It is the disease that is due to the invasion of the body by pathogenic germs, which establish and multiply caused by a local cell injury, secretion of toxins or by the antigen-antibody reaction.
The stage of an infectious disease called the Period of invasion is the time interval between invasion by an infectious agent and the appearance of the first signs and symptoms of the disease.
Therefore, we can conclude that according to the research, the correct option is Period of invasion. The stage of an infectious disease when specific signs and symptoms are seen and the pathogen is at peak activity is the Period of invasion.

Answer:
The pattern in which blood flows from the left side of heart the body , left foot and back to the heart is written below.
Explanation:
Left ventricle. ... As the heart contracts, blood eventually flows back into the left atrium, and then through the mitral valve, whereupon it next enters the left ventricle. From there, blood is pumped out through the aortic valve into the aortic arch and onward to the rest of the body
This is how blood flows through left side of the heart: The pulmonary veins empty oxygen-rich blood from the lungs into the left atrium. 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.
For the blood to flow back the heart...
The valves close when blood starts to flow in one direction, so that blood in the veins can only flow in the direction back to the heart, which is up the legs. ... So it is a combination of blood pressure from the heart's pumping action, the valves, and muscle movement that gets the blood up the legs against gravity.
range of fluid intake would be most appropriate : 50-70%
What is average?
In everyday terms, an average is one number chosen to represent a list of numbers; it is often the sum of the numbers divided by the number of numbers in the list (the arithmetic mean). The average of the numbers 2, 3, 4, 7, and 9 (which add up to 25) is, for instance, 5. An average could be another statistic like the median or mode depending on the situation. Because the mean would be falsely high if it included the personal incomes of a few billionaires, the median—the amount below which 50% of personal incomes fall and above which 50% of personal incomes rise—is sometimes used instead.
