The heart is the organ that provides both blood and oxygen throughout the whole body. First, deoxygenated blood enters the right atrium via the vena cava and when the pressure inside the atrium becomes higher than that of the right ventricle, the tricuspid valve opens and allows the blood to flow from high to low pressure. The valve then closes to ensure blood only flows in one direction (Tandy 2017). After oxygenation, the blood enters the left atrium via the pulmonary veins and fills it until…

the heart is a complex organ made of muscle and is compromised of four chambers including a right and left atrium and corresponding ventricles. the function of the heart is to pump oxygen rich blood throughout the body while receiving blood and sending it to the lungs to be re oxygenated then repeating the cycle. all of the body's different tissues require this oxygen rich blood to perform their functions. however, there are many problems that can affect the function of the heart. some of these…

part of the body to the right atrium. The posterior vena cava is part of the circulatory system. Heart: The heart is a thick muscle located near the center of the chest between the lungs. It looks like a quenched fist, pinkish in color and is surrounded by the pericardium. Its function is to pump oxygenated blood from the heart to the rest of the body and supply them with blood. The heart is part of the circulatory system. Pericardium: The pericardium protects the heart from infections and…

The Limulus polyphemus has a primitive blood. According to Bang & Levin (n.d.) the Atlantic horseshoe crab blood carries oxygen and has a special pigment that is a protein called hemocyanin. Homo sapien blood has a very similar protein in it called hemoglobin that makes the blood red from iron in the blood. Hemocynanin has copper molecules in it causing the Atlantic horseshoe crab to have blue blood. The hemocytes (blood cells) in the blue blood have a special clotting aspect. The hemocytes…

As I read through the laws that govern the securities industry, I asked myself the question of “ Why do we regulate the financial systems? Besides the basic understanding of having laws to better the efficiency of the investment and banking industry, why must we have laws and ethics that lay out the information of what is good and what is bad in the world of money, shouldn’t it already be known? In class we mentioned the issue with Goldman Sachs, ENRON, and some others companies who disobeyed…

Someone who is foresighted can confront many situations of life; despite the contingency life can have. “The Ant and the Grasshopper” is an Aesop’s Fable adapted by Jean de la Fountain. It has been adapted throughout the ages. Aesop was a legendary Greek fabulist (620–560 BC). He was a reputed creator of numerous short tales about animals, all of these illustrated human virtues and failings (World Encyclopedia). The french poet and man of letters Jean de La Fontaine (1621-1695) was one of the…

What separated the Ant from the Grasshopper was the Ant’s refusal to live in the now. Its animalistic nature to survive compelled the Ant to work diligently to store a supply of nourishment for the winter season again. On the other hand, the Grasshopper enjoyed feeling “alive” (Conklin, 2010, p. 60) and conducted himself in a recreational manner, though he witnessed the Ant’s effort to labor for its future. “Why bother about winter?” said the Grasshopper; “we have got plenty of food at present”…

For over 55 years, humans have been flying in space. With an understanding of evolution, it has always been assumed that human bodies have adapted to the gravitational force found here on Earth. The space station and the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards…

In the body, cells and organs usually receive the proper amount of blood and oxygen needed to keep the body running. However, when the cardiovascular system fails, the tissues and organs in the body don’t receive and adequate amount of blood and oxygen it needs, this is called shock. Shock is when blood circulation decreases and eventually stops. Shock can be cardiovascular and non-cardiovascular. There are three main cardiovascular causes of shock, which are; poor pump function, blood or fluid…
