Arthropods Vs Annelids

All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans, pigs, crayfish, and earthworms. From their mushy, gushy organs to their soft, gentle skin, you may think, “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be, but in other ways, they are very much alike. The body systems that will be compared and contrasted of these organisms are the nervous, circulatory, reproductive, muscular, integumentary, digestive, excretory, and skeletal systems.

When society thinks about crayfish and earthworms they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of both animals before going into major detail about them. According to the online website named dictionary.com, it says that an earthworm is a burrowing annelid worm that lives in the soil. Earthworms play an important role in aerating and draining the soil and in burying organic matter (Dictionary). Crayfish are nocturnal freshwater crustacean that resembles a small lobster and inhabits in streams and rivers (Dictionary). Crayfish and earthworms are some very interesting animals that possess some exclusive qualities both similar and different.

1. Gathered all required materials to designated lab bench. 2. Considered all safety precautions including the prevention of spilling water to avoid falls, handling glassware carefully to prevent shattering, avoiding long periods of working with warm water to avoid burns and avoiding the digestion/inhalation of by-products produced after the reaction (e.g. ethanol and carbon dioxide gas). 3.

There are guidelines/protocols that have been put in place by the trust that must be adhered to by all staff. Ensure that I am dressed appropriately so that my clothing does not compromise my safety or the patients. Ensure work/clinical areas void of equipment that may constitute a hazard if stored or left in the wrong place. There is adequate information and training provided by the trust to ensure competency and safe working. For instance, when in the mould room, I have been trained to use equipment and been made aware of safe working when using the various materials and substances in the mould (i.e. lead, hot water). The body absorbs lead when you breathe in the lead dust or swallow lead when you bite your nails after working with lead

Mr. Jones gave the class a brief overview of what they would be doing during the lab and he stressed to the class, “Please be sure to follow appropriate lab safety procedures.”

In order for the pathology service to work as a whole, a safe environment must be established as well as procedures which can be implemented if this safety is compromised. In order to do this pathology staff such as biomedical scientists must attend mandatory health and safety training meetings. For example, during my placement within the hospital, I had to attend a fire health and safety training meeting which was coordinated by qualified members of staff that aimed to educated attendants by providing relevant information. In the case of fire training, the use of particular fire extinguishers was explained. Any misconceptions brought up during these meeting were also resolved to endure that each member of staff clear about the information

rest assured that labs do not come back as quickly when not crammed into a 40minute

All staff should know the standard safe working practices in a lab. They must know the types of hazard that they face; the worst event which could occur; and also the personal protective equipment and facilities which will reduce these risks. Safety showers and eyewash stations are included in these facilities. Lab employees must know where these are situated and how to use them. Each employee should also be familiar with all alarm signals, the evacuation procedures and the response to an emergency. If the lab worker knows all these then they should be safe while working.

Throughout the practical investigation, there were a variety of safety precautions implemented. This not only prevented physical injury, but allowed the efficient progress of the practical investigation in a safe manner.

When one is working in a laboratory there are many different methods and procedures one must follow to ensure safety. There are three main concepts to ensure lab safety; these are hand washing, personal safety, and proper disposal of materials. Following these protocols would not just helps ensure the safety of me, but also the safety of the ones around me working in the laboratory. These protocols are necessary to ensure optimal experience for the professor and students in the lab. Methods and Materials

Sponges are considered part of the Animal Kingdom because sponges are multicellular. They are known be diploblastic, which means having two layers of cells. Adult Sponges, may have several cell layers, but originally, they all arise from the two layers that were present in the early embryo (Dawkins 2004). Most sponges are asymmetrical, however some of them show the radial symmetry (Dawkins 2004). Sponges do not have a coelom. A coelom is a cavity within the body in which the heart, intestines, kidney, lungs, etc., they are located, and it is sealed off from the outside world. The body cavity of sponges is large, and it is open to the outside world, also it’s enables the sponge to consume food (Dawkins 2004).

Arthropods are the most successful group of animals because they are the most diverse and live in a greater range of habitats than do the members of any other phylum in the animal kingdom. They are the most numerous living animal species currently known in the world and there may be millions more to be identified. (Myers, 2001) Some species known are insects, spider and crustacean and all are considered invertebrates, which means their bodies do not have internal bones for support. Instead, they produce a hard exoskeleton made of chitin which covers and protects their bodies and as they grow that protective barrier sheds away and are left with a soft exoskeleton. All arthropods have jointed legs attached to their hard exoskeletons that allow

The insect that i have chosen to compare to the cardiovascular system of with a mammals is an ant ( Anoplolepis gracillipes).

When assisting the patient, the radiographers have to make sure they provide radiation safety not only for the patient but also for themselves. There are many different methods to providing safety. With the equipment and radiation dosage, highest KVp and the lowest mAs is used to provide the minimum amount of dosage required for the procedure. Furthermore, safety can be provided by reducing the amount of rime in radiation area, by putting as much distance between you and the radiation source as possible. When performing a portable examination stand at least six feet from x-ray source and wear a lead apron. The patient should remove any jewelry or metal accessories that may interfere with radiation procedure and both the technologist and the patient needs to wear protective lead shields for example lead gloves, aprons, skirts and thyroid shields to protect the other body parts from the radiation. It is advised to also always wear monitoring device at collar level. Lastly, the technologist uses immobilization devices to hold the patients when needed.

If humans evolved to be arthropods, our lives would be very different. Arthropods have a completely different body structure; they have segmented bodies and often have over four legs. Sometimes they have wings, like bees do. This would completely change our daily life; if we could fly, it’s possible transportation would be much easier. We may suffer from less minor injuries such as scratches since our outer body is less squishy. To eat, shoving food in our mouth would be the only option. Speaking of food, our diet wouldn’t be as we know it. It’d all have to be natural and unprocessed.
