The 31 Types Of Invertebrates

Flatworms (Phylum Platyhelminthes)

Some are predators in freshwater and marine habitats. Cestodes (tapeworms) and trematodes (flukes) have complicated life-cycles, with mature phases that stay as parasites in the digestive methods of fish or land vertebrates. Invertebrates don’t have bony skeletons like vertebrates, nevertheless, many have an internal or exterior skeleton of some type which is produced from varied supplies.

This is definitely seen in snails and sea snails, which have helical shells. Slugs seem externally symmetrical, but their pneumostome (respiratory hole) is positioned on the proper side. Other gastropods develop exterior asymmetry, corresponding to Glaucus atlanticus that develops asymmetrical cerata as they mature.

In such mollusks, digestion is essentially intracellular, as could be anticipated in animals that eat microscopic meals. Current principle holds that the earliest vertebrates had been filter feeders. Some of the largest whales are examples of contemporary-day filter-feeding vertebrates; they pressure small planktonic organisms from vast quantities … Read More

Ultrasound For Pregnancy, Transvaginal & Other Types

Ultrasound For Pregnancy, Transvaginal & Other Types

ultrasound

It produces pictures of the inside of the physique using sound waves. Ultrasound imaging is also known as ultrasound scanning or sonography. It makes use of a small probe called a transducer and gel placed instantly on the skin.

After the French physicist Pierre Curie’s discovery of piezoelectricity in 1880, ultrasonic waves could be deliberately generated for business. Thereafter, in 1940, the American acoustical physicist Floyd Firestone devised the primary ultrasonic echo imaging gadget, the Supersonic Reflectoscope, to detect inner flaws in metal castings. Ultrasonic energy was first applied to the human physique for medical purposes by DrGeorge Ludwig at the Naval Medical Research Institute, Bethesda, Maryland, within the late Forties. English-born physicist John Wild (1914–2009) first used ultrasound to evaluate the thickness of bowel tissue as early as 1949; he has been described as the “father of medical ultrasound”. Subsequent advances within the subject occurred concurrently in a number … Read More
