relaxed. It is healthy to smile; the girl in the image looks healthy. Not only does smiling boost your immune system and lowers your heart rate; it also lowers your blood pressure. The University of Kansas studied the effects of smiling and blood pressure. They discovered that those who were smiling had a lower blood pressure than those who were not smiling. So smile because it is healthy for you. Last but not least‚ smiling helps longevity and looks. As you can see in the photo‚ the girl

The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

Introduction Stroke is a is a medical emergency and can cause permanent neurological damage and death.Risk factors for stroke include old age‚ high blood pressure‚ previous stroke or transient ischemic attack (TIA)‚ diabetes‚ high cholesterol‚ tobacco smoking and atrial fibrillation.1 High blood pressure is the most important modifiable risk factor of stroke.1 It is the second leading cause of death worldwide.2 Trends of mortality from stroke Stroke was the second most frequent cause of death

contributing indicator of these ailments is high blood pressure. Blood pressure is the force of blood against your artery walls as it circulates through your body. When you have high blood pressure it can harden your arteries‚ which decreases the flow of blood and oxygen to the heart. This in turn causes chest pain‚ heart failure‚ heart attacks‚ and strokes. According to the Center for Disease Control (CDC)‚ 67 million U.S. adults have high blood pressure which figures out to be 1 in every 3 adults

Measuring blood pressure has been an evolutional process in medical history. The results of a blood pressure can be indicative of many things. It plays a very important role in the health care management of individuals. Exercise is a great way to manage blood pressure levels and to keep them within optimal range. However‚ immediately after exercise it can be slightly elevated. Pulse pressure‚ heart rate and mean arterial pressure are also considered. The results varied depending on the individual

rate‚ temperature and blood pressure before and after exercise. Blood pressure is the measure of how much pressure is put on the walls of the blood vessels when the blood is pumped through them. This is measured in two parts‚ the larger number on top is known as the systolic pressure‚ this measures the pressure as the blood is pumped away from the heart whereas the lower number (The diastolic pressure) measures the pressure as the blood returns to the heart. The normal range for a healthy blood pressure

How to Properly Take Blood Pressure Step 1 - Choose the right equipment: What you will need: 1. A quality stethoscope 2. An appropriately sized blood pressure cuff 3. A blood pressure measurement instrument such as an aneroid or mercury column sphygmomanometer or an automated device with a manual inflate mode. Step 2 - Prepare the patient: Make sure the patient is relaxed by allowing 5 minutes to relax before the first reading. The patient should sit upright with their upper arm positioned

The goal of this experiment was to explore how temperature would influence the rate of cellular respiration of beans. It was hypothesized that as the temperature of the beans increased‚ the rate of cellular respiration would increase as well. In this experiment‚ the independent variable was the temperature‚ which gradually increased as time went by‚ and the dependent variable was the rate of cellular respiration‚ which was shown by the change in the amount of CO2 and O2 in the container. During the

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable
