Heart Health How Does Heart Rate Change with Exercise

Introduction The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand. History of the Heart The science and history of the heart can be traced back as far as the fourth century B.C.

Most people believe that the heart is located on the left side of the chest because the bottom of the heart is tipped to the left. Therefore, you feel more of your heart on the left side. The heart is a powerhouse with muscular walls that contract, thrusting blood throughout the body’s blood vessels. The blood must flow in one direction in order for the heart to function properly. The three focal types of vessels are arteries, capillaries, and veins which form the circulatory system. These vessels, like elastic tubes, transport blood to every portion of the body. Arteries carry oxygen-rich blood away from the heart to all of the body’s tissues. They progressively become smaller as blood is carried further away from the heart. The capillaries are the small, thin blood vessels that connect the arteries to the veins. Nutrients, carbon dioxide and waste products are allowe d to pass to and from the tissue cells by their thin walls. Veins, on the other hand, carry the oxygen-poor blood back to the heart. These vessels gradually become larger as they get near to the heart. The blood vessel system runs over 60,000 miles long. Heart Rate Your heart rate, also known as pulse, is the number of times your heart beats or contracts per minute. Due to the variation of the effects on hearts, rate fluctuates from person to person.

Greek Mythology Essay - 1090 Words

The characters in Greek Mythology can have several different interpretations. Among these characters are the dangerous, yet gorgeous Sirens, bird-women who sit on a cliff singing bewitching songs to captivate the minds of innocent travelers and bring them to their deaths. In Homer’s The Odyssey and Margaret Atwood’s â€Å"Siren Song,† both poets give different portrayals of the Sirens. Homer believes the Sirens to be irresistible in order to establish men as heroes whereas Atwood depicts them as unsightly and pathetic so she can prove men are foolish and arrogant using imagery, diction, and point of view. Homer wants the overall portrayal of the Sirens to be intriguing and desirable because he wishes all to consider Odysseus as valiant. Homer†¦show more content†¦Once the men are drawn to the Sirens, they are stuck and there is no way for them to escape. Furthermore, Homer explains the encounter with the Sirens from Odysseus’ point of view. The Sirens try to attract Odysseus by singing compliments to â€Å"famous Odysseus† so he will think that he is the object of their desire (14). The Sirens are intelligent enough to know what Odysseus’ true weaknesses are, flattery and the desire for recognition; his faults are similar to other men, however they do not yearn for knowledge. When Odysseus sails by, they attack his weaknesses, just as they do the other ships. Nonetheless, Odysseus is able to outsmart them. The Sirens sing to him and promise he will be able to â€Å"[sail] on a wiser man† if Odysseus listens to their song (18). He falls for their t rickery and attempts to join them, risking his life to gain the knowledge that the Sirens guarantee. Odysseus navigates himself through the sea with hopes of becoming smarter. Homer describes the Sirens as beautiful yet cunning because of their ability to identify men’s weaknesses easily. Their beauty attracts men and thus draws them toward their death. Homer’s view of the relationship between Odysseus and the Sirens prove that men are able to overcome temptations.

All of these various cultures have remained fairly distinct and in todays society each grouphas its own style of life and culture. EconomyIn 1966, Guyana was in the early stages of developing its resources. The British drew up aneconomic plan to continue development with the help of experts from the United States as well as Canada. The economy in the late 1980s was dominated mainly by agriculture and service industries. Theseindustries pulled in an average revenue of approximately 164 million dollars per year and an averageexpenditure of 284 million dollars per year. The agriculture is about one-fourth of the countries gross domestic product. Sugar and itsby-products and rice account for most of the exports. Coconuts, coffee, citrus fruits ,corn and othertropical fruits and vegetables are grown mainly for consumption. Another major crop that is raised on theplush savanna lands are livestock such as cattle, hogs, sheep and chicken. Along the coast is where much of the cultivation takes place. The tremendous strips of alluvialsoil are very rich in nutrients. A big problem that these coastal lands see are much flooding andirrigation problems such as drainage. This happens because much of this land is below the high-tide markof the sea and the rivers. Guyanian government is trying to help this problem by reclaiming some land forcultivation. .ue502237caa6fbeb0d3225b8f40990a2e , .ue502237caa6fbeb0d3225b8f40990a2e .postImageUrl , .ue502237caa6fbeb0d3225b8f40990a2e .centered-text-area { min-height: 80px; position: relative; } .ue502237caa6fbeb0d3225b8f40990a2e , .ue502237caa6fbeb0d3225b8f40990a2e:hover , .ue502237caa6fbeb0d3225b8f40990a2e:visited , .ue502237caa6fbeb0d3225b8f40990a2e:active { border:0!important; } .ue502237caa6fbeb0d3225b8f40990a2e .clearfix:after { content: ""; display: table; clear: both; } .ue502237caa6fbeb0d3225b8f40990a2e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue502237caa6fbeb0d3225b8f40990a2e:active , .ue502237caa6fbeb0d3225b8f40990a2e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue502237caa6fbeb0d3225b8f40990a2e .centered-text-area { width: 100%; position: relative ; } .ue502237caa6fbeb0d3225b8f40990a2e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue502237caa6fbeb0d3225b8f40990a2e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue502237caa6fbeb0d3225b8f40990a2e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue502237caa6fbeb0d3225b8f40990a2e:hover .ctaButton { background-color: #34495E!important; } .ue502237caa6fbeb0d3225b8f40990a2e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue502237caa6fbeb0d3225b8f40990a2e .ue502237caa6fbeb0d3225b8f40990a2e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue502237caa6fbeb0d3225b8f40990a2e:after { content: ""; display: block; clear: both; } READ: Individuality in 20th Century EssayMiningBauxite is one of Guyanas major elements.
