How are blood cells and stomach cells similar? (1 point)

WINSTONCH [101]

The similarity between the blood cells and stomach cells is ; Both help maintain homeostasis ( B )

The stomach cells helps in the storage of food ,enzyme secretion and digestion of food substance consumed. this way they help to maintain the acidity and water level in the body through the process of food digestion and enzyme/acid secretion.

The blood cells transports oxygen from the lungs to the tissues where they are needed and also taking back CO₂ from the tissues to the lungs. the blood cells also carries the necessary nutrients from the digested food to the various tissues. this way the blood cells help to maintain homeostasis in the body.

Hence we can conclude that the similarity between the blood cells and stomach cells is ; Both help maintain homeostasis

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the haematocrit is _______

nordsb [41]

Answer:

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the hematocrit is 41,02% percent. The hematocrit value is within the normal range.

Explanation:

Hello!

Hematocrit (or packed cell volume -PCV-)is defined as the percentage of red blood cells (vol%) in a blood sample. One common method of determining it is by centrifuging a heparinized blood sample in a capillary tube at 10 000 RPM for five minutes. This separates the blood sample in two layers, formed elements (RBC and WBC) and Plasma.

The length of the layers is directly measured from the tube and represents the volume of packed cells and plasma. Since the number of white cells is negligible compared to the number of red cells, the formed elements are considered to represent the red blood cells.

The hematocrit can be calculated as the volume of packed cells divided by the total volume of the blood sample.

$\frac{PCV}{TOTAL(pcv+plasma} * 100$

In the question:

$\frac{32}{32+46} * 100$ = $\frac{32}{78} * 100$ = 41,02%

In humans the normal hematocrit range is 40,7% to 50,3% for men and 36,1% to 44,3%. Taking these reference values into consideration, this sample is within the normal range.

I hope you have a SUPER day!
