Susan Harrison Aims: 1. To make simple measurements of body parameters 2. To assess whether they fall in the normal range Introduction In this practical you are going to measure your height (cm) and weight (Kg)‚ % skinfold fat‚ pulse rate (b/min) and blood pressure (mmHg). Put values on Excel sheet provided. 1. Size Equipment: Stadiometer; weighing scales. Measure your height (without shoes) in centimetres (cm) and weight in kilogrammes (Kg). Compare your weight with reference

Formative Assignment Including PSAfor class IX PHYSICS 1. Motion is relative or absolute? Give reason. 2. Name the physical quantity that essentially changes as a body moves. 3. Is displacement or distance independent of path? How? 4. Give example of a motion in which distance is covered but there is no displacement. 5. Give one example of motion where‚ distance and displacement are same. 6. When moving car returns to the same point what will be the ratio of

To define ectopic pacemaker. I nvestigation of human cardiovascular physiology is very interesting‚ but many areas obviously do not lend themselves to experimentation. It would be tantamount to murder to inject a human subject with various drugs to observe their effects on heart activity or to expose

Part I: Pulse Rate Take your pulse at the wrist‚ as described on the Work Out tab of 4.02‚ and record it below. Your count for 30 seconds ___ x 2 = ___ bpmDay 1 _____Day 2 _____Day 3 _____Total _____ divide by 3 = _____ This is your Resting Heart RateObtain your Maximum Heart Rate (MHR) by subtracting your age from 220. Example 220 – 21 = 199 1. Subtract your resting heart rate (RHR) that you calculated in Part II above from the maximum heart rate (MHR) that you just determined in Step

Discussion Heart Rate Our hypothesis stated 1.) The heart rate increases substantially when a person performs a physical activity and 2.) Females have heart rates greater than males’. In this experiment we measured the resting heart rates and exercise heart rates of both the male and females that are in the class. We calculated the results that were taken by each member of each group in the class (6 males and 16 females total). The average resting heart rate for women was 71.8 beats per minute

Nicoleta Nedelcu Caffeine-induced effects on heart rate in zebrafish embryos and possible mechanisms of action Observation Caffeine is found in coffee‚ tea leaves‚ cocoa beans‚ and kola nuts. It is used in prescription and over the counter drugs. It increases blood pressure‚ mental alertness‚ and gastrointestinal motility. Cardiovascular development with caffeine and other small molecules can be studied relatively easy using zebrafish. The cardiovascular system is complete in two days after fertilization

Darra Boyer November 18‚ 2015 Affects of Various Drugs on the Heart Rate of Daphnia magna Introduction The Daphnia magna‚ more commonly known as water flea‚ is indigenous to ponds and lakes in northern and western North America. This crustacean has an outer transparent covering called the carapace. The unique physiology of the water flea is useful in translational research allowing researchers to visibly study all of the bodily systems without causing harm to the specimen (2). Being classified

Ligands: Examining the effects of pharmaceutical compounds on Daphnia magna physiology Abstract The following study was conducted in order to determine the effects of four different pharmaceutical compounds on the heart rate of Daphnia specimens. After basal heart rate was observed and computed‚ four different solutions each containing either an adrenergic‚ muscarinic‚ or nicotinic agonist or antagonist was tested against individual Daphnia. Observations were made through a compound light microscope

Caffeine in the diet Email this page to a friend Bookmark & Share Printer-friendly version Caffeine is a substance that is found in certain plants. It can also be man-made (produced synthetically) and then added to food products. It is a central nervous system stimulant and a diuretic (substance that helps rid your body of fluids). Function Caffeine is absorbed and passes quickly into the brain. It does not collect in the bloodstream or get stored in the body. It leaves the body in
