Transcript of Blood cell Analogy

Erythrocytes are red blood cells that transport oxygen into the blood and carbon dioxide out of the body. There are around 4.5 to 6 million erythrocytes per square mm, with a life span of approximately 120 days. To make more room for oxygen storage , they do not have a nucleus or organelles after they are produced in the bone marrow. They have a circular, biconcave structure
T-cells recognize and attack involving microorganisms such as bacteria and viruses.
B-cells produce antibodies that react with microorganisms, or bacterial toxins, as part of the immune system. Plasma cells that contain antibodies are manufactured by the B-cells, and spread into the bloodstream.
Analogy: The City
We are comparing the blood cells in the body to the different workers and employees in a city system.
Thrombocytes are platelets which coagulate when there is damage in the blood vessels, making a blood clot. There are approximately 250 000-500 000 thrombocytes per square mm and have a lifespan of 10 days. Thromocytes are made up of small fragments of megakaryocytes.
Blood Cell Analogy:

Erythrocytes: Bus drivers
Thrombocytes: Construction workers
B-lymphocytes: Mechanical engineers
T-lymphocytes: Military
Monocytes: Janitors
Basophils: Doctors
Eosinophils: Pest Control
Neutrophils: Police

Analogy: Bus/ Taxi Driver
Both erythrocytes and bus/taxi drivers' main job is to transport important components. Erythrocytes transport oxygen and carbon dioxide through the body. Likewise, taxi/bus drivers carry citizens through the city. Citizens are important to the city just as oxygen is important to the body. Taxi drivers move through, and reach all parts of the city; similar to how erythrocytes transport oxygen all throughout the body. In addition, there are great amounts of both Erythrocytes in the body and taxi/bus drivers in the city.
Analogy: Construction Worker
Thrombocytes clot blood which is similar to how builders create structures. For instance, a construction worker can build a dam to control water flow and protect the city from loss of water. Likewise, thrombocytes coagulate to stop blood from escaping the body. Another example is how construction workers create road blocks to stop cars from going into a certain area. In comparison, blood clotting controls where the blood flows.
Analogy: Mechanical Engineer
B-lymphocytes are similar to mechanical engineers, more specifically weapon manufacturers, because they both produce a protection to deal with the enemies. B-cells produce antibodies similar to how mechanical engineers produce weapons. Both weapons and antibodies have potential to fight off invaders.
Both the T-cells and military attack the enemy, or invader, directly. T-lymphocytes may reject foreign organs such as a heart transplant. This action is similar to how a military might have to turn against their city in order to control a riot.
Monocytes engulf bacteria and cellular debris to finish the cleaning process started by the neutrophils. They increase in times of inflammation, or in necrosis. When monocytes leave the blood, they are called macrophages.
Monocytes clean up the debris started by neutrophils, similar to how janitors clean up waste that the citizens, or consumers, throw out. Both neutrophils and citizens clean up waste to a certain degree, and both monocytes and janitors finish up the job.
Basophils secrete histamine which dilates the blood vessels in a process called vasodilation. This process increases bloodflow when tissue is damaged, or when there is an allergic reaction. Basophils also secrete heparin and anticoagulant to prevent blood clots from forming. These cells take up 1% of the blood volume and are called mast cells in tissue.
Basophils control the flow of blood in the same way that traffic directors control the flow of cars. Basophils prevent blood clotting; similarly, traffic directors prevent traffic jams. Blood is related to the cars because they are both used to transport important things; cars transport citizens and blood transports oxygen. Dilation of blood vessels represents the traffic directors giving the cars more space to move.
Analogy: Traffic Director
Eosinophils are comparable to pest control because they both release a substance to kill off a pest or intruder. Pest control releases pesticides in the same way that eosinophils release histamine. The pests are similar to parasitic worms because they both are invasive and unwelcome.
Analogy: Pest Control
Neutrophils are the first responders to damaged tissue. They engulf bacteria though a process called phagocytosis.They increase during an acute bacterial or fungal infection.
Both policemen and neutrophils are the first responders to an incident.Policemen are one of the first to arrive at a crime scene; likewise, neutrophils are the first to respond to tissue damage.
Analogy: Police
These cells neutralize histamine and they destroy parasitic worms. Their numbers increase during a allergic reaction or a parasitic infection.
