Grasshopper Circulatory System Essay

neuroendocrine system for support. The Hematologic system responds to major blood loss by activating coagulation cascades and constricting the vessels that are currently bleeding by release of thromboxane A2 and platelets. What this does is form a colt on the bleeding site. Collagen is exposed by damaged vessels which cause fibrin production and stabilize the clots that have been formed. Usually it takes between 15-25 hours for a clot to mature in form. Joannes cardiovascular system is…

The Cardiovascular System is one of the most important systems in the body of an organism. It is responsible for carrying the oxygen and nutrients needed for survive through the body. The only organ in this system is the heart, containing four chambers; the left and right atrium and the left and right ventricle, which will be described in further detail later on. Although this system is very important, problems can occur that disrupt the normal routine. One of these we will be focusing on today…

4. Estimating for a deer population (N) is considerably different than estimating a big bluestem population. The methods for estimating a big bluestem would be extremely difficult because grasses are known for being colonial, meaning that the root system is interconnected to other big bluestems that originate from the same seed making it very difficult to distinguish and count an individual. The methods for estimating a deer population are described…

The lesson called Home Grown Caterpillars is a lesson about the transformation of a caterpillar to a butterfly (life cycle process) while creating a three dimensional piece of art to express idea, experience, or story. The story associated with this lesson is The Very Hungry Caterpillar. The art piece is a replica of the caterpillar during a butterfly’s life cycle made out of grass seed, soil, stockings, pipe cleaners, and googly eyes. This lesson would be considered an art enhanced lesson…

There is a charming story tilted Giraffes Can’t Dance by Giles Andreae. In the story, the giraffe is sad because he can't dance like all the other animals. That’s when the cricket shattered his perspective with this jaw dropping quote. He said, “‘ Excuse me’” said a cricket “‘ but sometimes when you’re different you just need a different song’” “‘ Listen to the grass and listen to the trees’” (Andreae). The cricket puts the message of the whole story into one simple sentence. He is telling the…

In Christopher Morley's poem "Nursery Rhymes for the Tender Hearted", the speaker wonders about a cockroach he spots running through the pantry. "Roaches", by Peter Wild, has a similar subject matter, where the speaker spots a cockroach in the bathroom, kills it, then reflects on the bug. Each poem suggests a very different impression of the cockroach: Morley's is a sweet, innocent child, while Wild's is dangerous, unwanted predator. The ideas between these poems are fairly similar however, the…

Based on our findings, the NSAIDs aspirin and ibuprofen do have an impact on the heart rate of the Lumbriculus variegatus worms as evidenced by Figures 2 and 3 above. We observed that caffeine also had an impact on the heart rate of the worms. We can state that our hypothesis was correct when it came to the ibuprofen solutions because evidence supports the claim that the ibuprofen does increase the heart rate in Lumbriculus variegatus. Furthermore, as the concentration of ibuprofen increased,…

Blood, Guts and... Am I cut out for this? Receiving that unexpected yet exciting text message, was like an invitation to meet the Queen or maybe better in my case. Was I going to hold a human beings heart in which I had no idea who they were or have any clue what I was doing. Or maybe I was going to be lifting their blood pumping organ out of his chest like a sacrifice I was making to the hospital gods. I drove down to the hospital as calmly as possible, trying not to let my thoughts get the…

Normally, as the heart contracts, it is able to exert a pressure that drives blood throughout the cardiovascular system and allows for perfusion as well as gas and nutrient exchange to take place. This blood flow is typically described by the equation Q=P/R, where Q represents blood flow, P is the pressure gradient, and R stands for total peripheral resistance.1 In a well-functioning system, a general balance is maintained between the pressure and resistance, which allows blood to reach all…

Demonstrate the role of stents in Percutaneous Coronary Intervention (coronary angioplasty) Introduction The heart is a pump that circulates blood to the rest of the human body. It is positioned at the centre of the chest, just between the lungs. The network of blood vessels that branch over the surface of the heart are the coronary arteries. Figure 1 outlines the coronary arteries on the heart which supply the cardiac muscles with nutrients such as oxygen and glucose needed to survive [1].…
