What is the functional significance of the walls of large arteries having an abundant supply of elastic fibers

1 answer:

4 0

The significance of large wall arteries having an abundant supply of elastic fiber is it expand to accommodate this high pressure, then recoil to their original shape to move the blood along.

<h3>Significance of Wall of Large Arteries</h3>

The significance of large wall arteries is large arteries receive large amounts of blood with tremendous pressure so the elastic fibers allow these vessels to expand to accommodate this high pressure, then recoil to their original shape to move the blood along.

List the functions of proteins in the text area below.

Wittaler [7]

Answer: 1- Maintenance of oncotic pressure: prot. are macromolecules that hydrate in the plasma and exert a PO retaining water in the vascular medium, all prot. mainly albumin

2- Buffer role: all prot. Plasma acts as a buffer because of their hydrophobic character thus participating in the regulation of acid-base balance

3- Transport function Albumin.Tyroxine binding protein (TBP), transferrin, apoproteins..etc.

4- Enzymes and coenzymes: renin, orosomucoid (coenzymes of LPL)

5- Role in coagulation and fibrinolysis: fibrinogen, thrombin. antithrombin

6- Role in immunity: Ig (lgA JgG.lgM) and complement proteins

7- Role in the allergic: IgE and complement fractions

8- Role in inflammation: α1 antitrypsin, orosomucoides .cerulioplasmin, cytokines, CRP

9- Hormonal role: insulin, glucagon, pituitary stimulins (TSH, FSH, LH)

10- And finally a structural role (such as actin or tubulin that participate in the architecture of the cell, the keratin that makes

¿Cómo se le llama a los que pudieron dar origen a los seres vivos actuales?

natta225 [31]

Answer:

Una de las características de los seres vivos se encuentra en su composición biológica, dado que todos ellos están constituidos por cuatro bioelementos esenciales que se encuentran de manera abundante en la naturaleza:

Carbono

Hidrógeno

Oxígeno

Nitrógeno

Estos bioelementos o elementos biogénicos están presentes en las biomoléculas, que son las que dan forma a la materia que constituye a los seres vivos. Estas moléculas están formadas, a su vez, por la unión de átomos.

De estos bioelementos, es importante destacar el papel del hidrógeno y el oxígeno, que dan lugar a la molécula del agua. El agua, o H2O, juega un papel fundamental en el funcionamiento de los seres vivos.

I REALLY NEED HELP!!!!!

laila [671]

Answer:

Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. ... this is actually why cells divide.

alukav5142 [94]

The intermediate disturbance hypothesis predicts that species diversity will be highest when the frequency and/or intensity of disturbances are intermediate

Explanation:

The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.
