Explanation:
Atomization refers to separating something into fine particles.
The opening into a larynx is called a glottis.
Archimedes was an ancient Greek mathematician and inventor. He made mathematical discoveries as he solved everyday problems. He invented machines to move heavy objects, carry water, and fight battles. Archimedes recorded his discoveries so that others could learn from them. Today he is considered one of the greatest mathematicians of all time.
Archimedes was born in the Greek city-state of Syracuse, Sicily, in 287 bc. His father, Phidias, was an astronomer. Archimedes also studied astronomy.
It is believed that Archimedes visited the famous library of Alexandria, Egypt, where he met great scholars. While in Egypt, he is said to have invented a machine to carry water upward from one level to another. The machine, known as Archimedes’ screw, is still used in parts of the world today.After studying in Alexandria, Archimedes returned to Syracuse. He wrote many works to explain his discoveries. Archimedes’ most-famous ideas include his explanations of how levers and pulleys can lift and move heavy objects. Another idea, called Archimedes’ principle, is a scientific law. It describes what happens when an object floats in water.
In 213 bc Romans attacked Syracuse. Archimedes invented machines to defend the city. When Syracuse was finally overtaken, Archimedes was killed there in 212 bc.
<h2>Anatomy of Aorta</h2>
Explanation:
- The protein elastin is found in connective tissues all through the body. It is eminently found in the extracellular lattice of the skin just as the inward organs of the body. The name elastin sounds a lot of like 'flexible.' This is no fortuitous event. The elastin protein is adaptable and gives numerous tissues their versatility.
- Inferable from its exceptional capacity to extend and withdraw, the aorta additionally fills in as a store that changes the profoundly compelled and pulsatile heart yield into a progression of moderate variances.
- The tunica intima comprises of a solitary layer of ECs that lines the lumen of the vein and is moored to the fundamental cellar film, an exceptionally particular ECM organize comprising basically of laminin, collagen type IV, fibronectin, perlecan, and heparan sulfate proteoglycans.
- This storm cellar layer additionally assumes a vital job in flagging occasions that direct EC movement, intrusion, expansion, and survival. The cellar film together with the inward flexible lamina (IEL) fills in as an interface between the tunica intima and tunica media.
