Answer:
b. laminar flow
the reynold number is 1329.26
Explanation:
Re = (V x D x ρ)/ η
where,
V = mean velocity = 15.9 cm/s = 0.159m/s
D = vessel diameter = 2.15cm = 0.0215m
ρ = blood density = 1050 kg/m3 = 0.00105 kg/cm3
η = dynamic viscousity= 2.70 × 10-3 Pa·s = 2.70 × 10-3 kg/m-s
applying the formular to calculate for reynolds number, Re =
Re = (V x D x ρ)/ η
=(0.159 x 0.0215 x 1050) / 2.70 × 10-3
=3.589/0.0027 = 1329.26
the Reynolds number for the blood leaving the heart through the aorta if the diameter of the aorta is 2.15 cm and the blood has a dynamic viscosity of 2.70 × 10-3 Pa·s, a density of 1050 kg/m3, and travels at a mean fluid velocity of 15.9 cm/s is 1329.26
which flow through the aorta in a Laminar flow
Note that
a) turbulen= Re >4000
b) laminar= Re <2300
c) transitioning between laminar and turbulen= Re between 2100 and 4000
The functions of proteins include:
- They transport oxygen in the blood of vertebrates.
- They play a key role in moving materials within cells.
- They help the body recognize and destroy foreign microbes and cancer cells.
- They catalyze chemical reactions.
<h3>Functions of proteins</h3>
Proteins are macromolecules that helps in the maintenance of metabolic activities and repair of worn out tissues of the body.
There are several functions of proteins which has helped in it's classification. The different types of Protein found in the body are:
- Antibodies: These are proteins that function to recognize and destroy foreign microbes and cancer cells.
- Enzymes: These are proteins that catalyze chemical reactions in the body.
- Transport proteins: They play a key role in moving materials within cells.
- Haemoglobin: These are blood proteins that transport oxygen in the blood of vertebrates.
