Each species of dolphin‚ whether marine or river‚ has an anatomy which allows them to thrive in certain conditions. The anatomy of the dolphin has been enhanced throughout the years in order for them to continue to adjust to their domain. This paper will break down the adaptions in the anatomy of one

Cardio Pulmonary Practical The main aim of the practical was to assess‚ what affects did light exercise have on the systolic and diastolic blood pressure‚ heart and respiration rate‚ tidal volume‚ minute volume and percentage of gas. The readings were taken before exercise‚ during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls‚ during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the

In 2014‚ Rouse & Sons‚ a small environmental-testing firm‚ performed 12‚200 radon tests for $290 each and 16‚400 lead tests for $240 each. Because newer homes are being built with leadfree pipes‚ lead-testing volume is expected to decrease by 10% next year. However‚ awareness of radon-related health hazards is expected to result in a 6% increase in radon-test volume each year in the near future.

The Cardiovascular System The cardiovascular system consists of a heart and an enclosed system of blood vessels categories into arteries‚ capillaries and veins. The heart is a muscle about the size of the fist; its wall is made up of a muscle known as the Cardiac Muscle‚ and is located between the two lungs and lies left of the middle of the chest (cliff notes). A fibrous covering known as the pericardium which surrounds around the whole heart holds the heart in place but allows it to move as

Phase 1- sodium channels close‚ potassium channels close‚ decrease in potassium and sodium. Calcium channels open‚ increase of calcium into cell. Phase 2- Plateau phase‚ membrane still depolarized (contract). Potassium channels closed‚ L-type calcium channels stay open. Lasts 0.2 seconds/200
