Pure Heart

defined as the amount of pressure of the blood vessels when the heart is at rest (diastole). DISCUSSION A) Pulse pressure In simplest words, the pulse pressure can be explained as the amount of pressure when the systolic pressure minus diastolic pressure. The unit is in mmHg. As per theory, the pulse pressure is proportional to stroke volume, or the total amount of the blood ejected by the left ventricle…

5 THINGS YOU SHOULD KNOW ABOUT TENS UNIT ELECTRODES In transcutaneous electrical nerve stimulation (TENS) treatment for pain relief, electric signals are transmitted from the device (known as TENS unit) through electrodes placed on the skin surface to the nerves under the skin. If you don’t use these electrodes properly, your body can experience discomfort or pain even though the signals are generally mild and safe. Here are 5 things you should know about electrodes in the TENS unit: 1. Where…

the chest that makes it difficult to breathe caused by poor blood flow to the myocardium) (the middle and thickest layer of the heart wall, composed of the cardiac muscle) (Miller, 2003). Upon checking his vitals the patient is noted to have an arrhythmia (when the speed or rhythm the heart is beating is not normal), while also suffering from tachycardia (when the heart beats exceeding fast, up to two hundred beats per minute in an adult). Consequently, review of his medical record shows…

prevented by simply addressing behavioral risk factors. The heart is responsible for pumping blood throughout the body. The arteries take the blood away from the heart and the veins bring it back to it, completing the circuit. This process is what brings oxygen, nutrients, and protection to the body 's cells. It is also the process that takes waste materials from the cells to be removed from the body. If the cardiovascular (cardio – heart, vascular – veins and arteries) system does not work…

The heart works by pumping the blood throughout the internal circulatory system to deliver the oxygen and nutrients to the body cells. There are some features about the heart which allows more efficient respiration system. The heart have a left atrium and left ventricle. The left side of the heart is called systemic circulation which only pumps the oxygenated blood to the body and the right side of the heart is called pulmonary circulation only pumps deoxygenated…

During pregnancy the cardiorespiratory system of the fetus adapts for survival in utero and then changes to an independent postnatal circulatory system. In order to understand the differences in fetal circulation versus postnatal circulation it is important to note that in a fully functioning not pregnant mammal blood circulates in the following way: vena cava, right atrium, tricuspid valve, right ventricle, pulmonary semi lunar valve, pulmonary arteries, lungs, pulmonary veins, left atrium,…

My temperature rises as if my cheeks were slowly absorbing the heat from a hot stove. I support the weight of high expectations on my shoulder from myself and my family. I get onto my starting block and after every second going by I can hear my heart beating in my own ears so deafeningly as if it were pounding on my ribcage to rip free from my chest. I concentrate on gulping as much of oxygen I can accommodate in my mouth like a lion deprived of food and is ferociously stuffing…

Circadian Rhythm – a cycle that tells the body when to rise, sleep, eat which regulates many physiological processes. The internal body clock is affected by cues. Like sunrise and temperature. According to Professor Russell Foster in 2007, an Oxford University Neurologist said that student would gain more if their classes start in the afternoon. Forcing a student who arrives in the morning could be a result of poor memory and stress. He also added that teenager's body clocks between two hours…

strengthening muscles and enhancing immune system. It reduces the risk of many diseases including heart diseases, obesity or diabetes. It also maintains mental health and boosts the confidence too. Types of Exercises Considering their reactions and the effects on a person, exercises are divided into two main categories: • Aerobic Exercises…

Gaseous exchange Breathing is the body’s way of exchanging oxygen for carbon dioxide. The lungs get oxygen through alveoli. The air is transported though the trachea and diverted though the bronchi into a lung, the bronchi extends into smaller tubes called bronchioles witch at the end of them are little air sacks (the alveoli). Oxygen is needed to get into the blood stream to allow oxygen to be supplied throughout the body in order for it to function normally. It does this by gaseous exchange.…
