Broken hearts

I. Heart is a muscular organ in human and animals which pumps blood through the blood vessels of the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide. II. Do you notice that on valentine day, people usually give heart-shaped candies to their partner? III. Do your ever hear a people singing about their broken heart when you are listening to radio or love song? IV. If you realised, we often see and hear about hearts everywhere in our daily life. V. But do

The heart is a very important organ in the body. It’s around the size of someone’s hand closed up together in a fist and is located in the chest between the lungs. The main purpose of the heart is to pump blood around the body ( The Structure of the Heart). The heart consists of epicardium, myocardium, and endocardium layers that protect its walls. The epicardium is the membrane of the external heart surface. The endocardium lines the interior portion of the chambers in the heart. Lastly, between

exercise levels are completed, then there will be an increase in those functions which include heart rate, breathing rate and carbon dioxide production levels. Materials: Test tube rack Safety glasses Measuring cylinder Dropper Balloon Large test tubes Stopwatch / timer Glass pipette 20 ml of water Bromothymol blue Up to four group members An exercise Pen / pencil Paper / tables to record information Method: Heart rate: A timer was taken out as a pulse was being found. Once found, in 30 seconds the pulse

This red liquid is pumped through the arteries and veins by the heart. Cardio- is a prefix that means heart. So, putting two and two together, the cardiovascular system pertains to the heart. The following essay will break down how the blood and heart function in the body. Blood is carried through arteries and veins, this allows for oxygen to be brought to tissues and for carbon dioxide to be taken away from tissues. Blood is broken down into two components: living cells and non-living cells. Non-living

Paraphrase: The inner hearts of trees are annually displaced, moving outward to a ring. They aren’t really what we mean by hearts; they easily give in, willing to thin and accommodate new growth from the center of the trunk. A real heart does not give in to the trivialities that come with a new year, a new spring. A real heart is true--and there will be no more springs without you. Imagery: The writer uses visual imagery to describe trees and compare them to human hearts. The line that trees are

Epithelial Tissue: Epithelial tissues line and cover the organs, capillaries and body cavities within the body. Epithelial tissues can be broken down into four types: Simple Squamous, Simple Cuboidal, Transitional and Stratified Squamous. Epithelial tissues are named first by their amount of layers they have, and second by the cell shape. Simple Epithelial tissues are composed of only one layer of cells, while stratified tissues are composed of more than one layer of cells. Squamous tissues are

a cell and it is where the glucose molecule is broken down through molecules. The enzymes used removes the hydrogen from glucose which is called oxidation this is where hydrogen atoms are taken to the cytochrome system. In anaerobic respiration the glucose splits into 2 molecules of pyruvic acid and when oxygen is produced the pyruvic acid is broken down into carbon compounds in the Krebs cycle and when oxygen is not present the pyruvic acid is broken down to lactic

men had ruled the earth for years together, the male gender is highly susceptible so far heart disease is concerned . More men are living with and dying of Coronary Heart Disesse (CHD) than women and have more hospital discharges for Cardiovascular disease ( CVD ) and CHD. The prevalence of CHD is higher in men within each age stratum until after 75 years of age, which may contribute to the perception that heart disease is a man’s disease. The classic risk factors for CVD are the same in women and

and scarring of the heart. CVD is commonly found in overweight people specifically teens. This is because there is a direct correlation between the levels of obesity and the diagnosis of cardiovascular diseases such as stroke. Firstly, cardiovascular disease refers to many sub conditions. To name a few; coronary heart disease, stroke, cardiomyopathy, peripheral vascular disease and congenital heart disease. Coronary heart disease occurs when the oxygenated blood supply to the heart is congested by plaque

workload, and any health issues that may affect this. Cardiovascular system This system is responsible for pumping blood and oxygen around the body. It is a network made up of blood vessels that transport carbon dioxide from the body to the lungs. The heart is an organ so needs a constant supply of oxygen. This is supplied by a separate network of blood
