In the ED, blood is withdrawn from the vein and into a test tube. The packed cell volume (RBCs) is 1.45 ml, and the plasma volum

Yuri [45]

Answer:

<h2>1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low),</h2>

Explanation:

HCT is calculated as:

HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100

1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT ranges from 38 to 46% (some sources claim 34.9-44.5%).

*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.

Total blood volume = Packed cell volume + plasma volume.

The names of the respiratory structures involved include the following: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli.

<h3>What is respiration?</h3>

Respiration is defined as the oxygenation of blood through the intake of oxygen and the removal of carbon dioxide.

The pathway of oxygen gas molecule from the surrounding air through the respiratory system to the blood include respectively the following:

Nasal cavities (or oral cavity): This has a direct association with the outside oxygen from the environment.

pharynx: This so also called the throat.

trachea: This is also called the wind pipe.

Primary bronchi (right & left): This divides from the trachea to form two bronchi.

Which transport mechanisms require the formation of a vesicles to transport material into or out of the cell?

Ksenya-84 [330]

The answer is D because <span>In </span>exocytosis<span>, materials are </span>exported<span> out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane. This fusion causes the vesicle to spill its contents out of the cell. Exocytosis is important in expulsion of waste materials out of the cell and in the secretion of cellular products such as digestive enzymes or hormones.</span>
