(a)
Interpretation:
The physical quantity that is measured while taking blood pressure should be identified.
Concept Introduction:
In our circulatory system, blood moves by a force that force is known as blood pressure. This force is important as it pushed oxygen and nutrients all around the circulatory system. If there is no blood pressure, oxygen and nutrients insufficiently reach the tissues and organs affecting their growth.
(b)
Interpretation:
The units in which blood pressure is typically measured should be reported.
Concept Introduction:

If there is no blood pressure, oxygen and nutrients insufficiently reach the tissues and organs affecting their growth.
(c)
Interpretation:
Whether the reported blood pressure an absolute pressure or a gauge pressure should be determined.

If there is no blood pressure, oxygen and nutrients insufficiently reach the tissues and organs affecting their growth.
(d)
Interpretation:
The difference in the readings when an ambitious zookeeper measured the blood pressure of a standing adult male giraffe in its front leg, just above the hoof, and in its neck, just below the jaw should be explained.
Concept Introduction:
The heart of the giraffe has a weight around 26 pounds and they move their neck from low to high in order to keep a continuous flow of the blood to the brain. Because, giraffes contain long neck, the blood vessels in the head lead the blood flow to the brain directly.
8-10 mm of Hg.
As the neck length and body mass increases, the systematic blood pressure also increments twice. This also results in increased hydrostatic pressure in the neck finally resulting in increased blood pressure in the neck compare to leg. The giraffe’s leg display arteries with increased volume and thickness. The increase in the number of smooth muscles in the legs results in more strongly contracted arteries than the neck leading to decreased arteria pressure when compared to the neck. The expected difference in the readings would be 8 to 10 mmHg.
(e)
Interpretation:
When giraffe stoops to drink what will happen to its neck?
Concept Introduction:
In our circulatory system, blood moves by a force that force is known as blood pressure. This force is important as it pushed oxygen and nutrients all around the circulatory system. If there is no blood pressure, oxygen and nutrients insufficiently reach the tissues and organs affecting their growth.
(f)
Interpretation:
How the giraffes accommodate themselves in pressure differences associated to the height?
