The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones‚ i.e.‚ in the center of the chest. Usually it is slightly on the left side of the chest but in rare cases‚ it can be found on the right side. Heart is responsible for the blood flow to every single part of the body by constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time. Heart pumps the pure blood to the different

The purpose of this experiment was to observe the process of human evolution by observing similar features of the Pan troglodytes‚ Australopithecus afarensis‚ Homo erectus‚ Gorilla gorilla‚ Australopithecus boisei and the‚ Homo neanderthalensis in comparison to those of the Homo sapien. According to Darwinism‚ the species that had the most traits in common with the Homo sapien must be the most related while species with the least traits in common with the Homo sapien were the least similar. For example

Aim: To examine and dissect a sheep’s heart‚ to observe it’s structure as a two-part pump and it’s features. Hypothesis : That the left side of the heart will be bigger because the left side of the heart pumps blood around the whole body. Apparatus: Gloves Dissection Board Sheep’s heart Scissors Aluminium Foil Newspaper Method : The heart was laid out with the septum coming diagonally from the upper right side to the lower left side. The heart clambers were observed‚ examined and recorded

Running Header: Peripheral Arterial Disease Peripheral Arterial Disease April 22‚ 2010 ME 1352 Abstract Peripheral Arterial Disease is a common secondary disease that follows Atherosclerosis. Once so much plaque builds up in the arteries‚ they become block the blood flow. P.A.D. usually affects the lower extremities and can cause intermittent claudication and‚ if severe enough‚ gangrene. Many people live with atherosclerosis and P.A.D. and show no symptoms. There are numerous prevention

Sarmiento Daphnia Ecotoxicology Lab Report Introduction Ecosystems have a way of maintaining themselves under ordinary conditions but when a new factor is added that will most likely threaten the environment action needs to be put forth. Our environment is affected by many pollutants on a daily bases forming a threat to natural stability. For example some of the most polluted parts of the environment are bodies of water like that explained in our lab. Once pollution occurs animals

Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used

Purpose: The purpose of the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister
