What is the correct hierarchy of the human body?

The structural organisation of the human body is very easy i.e. the general and basic structure CELLS form TISSUESform ORGANS form ORGAN SYSTEMS form HUMAN BODYExamples: CELL is any cell in the human body in any of the systems. For eg. Nerve cell(Neuron), Muscel cell etc. TISSUE- Many similar type of cells combine to form a tissue. For eg. A muscel in the human body, a nerve of the nervous system etc. ORGAN- Multiple tissues combine to form an organ. For eg. The heart, the stomach etc. ORGAN SYSTEMS- Many organs combine to form the organ system. For eg. The digestive system, the nervous system etc. HUMAN BODY- All the organ systems of the human body combine to form the body and help it function.


How fast does an average raindrop fall?

How fast does hail fall?We really only have estimates about the speed hail falls. One estimate is that a 1cm hailstone falls at 9 m/s, and an 8cm stone, weighing .7kg falls at 48 m/s (171 km/h). However, the hailstone is not likely to reach terminal velocity due to friction, collisions with other hailstones or raindrops, wind, the viscosity of the wind, and melting. Also, the formula to calculate terminal velocity is based on the assumption that you are dealing with a perfect sphere. Hail is generally not a perfect sphere!


What is the auscultatory method for blood pressure?

This is the old fashioned way to measure blood pressure which prescious few nurses these days seem capable of. The equipment used is a sphygmomanometer (the arm strap that inflates and tells you the pressure it has inflated to) and a stethoscop (the hearing thing). The sphyg is placed around the arm above the elbow (at the same level as the heart) with the pump tubing pointing down the cephalic vein (big blue line cant miss it). The patients elbow should be bent and relaxed lying on a comfortable surface. No placing the steth at the correct place at the top of the forearm roughyl bellow where the tubing points you should hear nothing yet. Pump uo the sphyg until reasonable high (some docotrs like to use set limmits other even try to hear the sounds during this phase to kow when to stop). Once you believe the pressure is high enough to be cutting of the circulation start to let it off slowly. Eventually you will hear a "knocking" sound which is the sound of the blood managing to force its way through during systole and so giving the systolic pressure. Now keep letting the pressure of even slower until the knocking stops, this is when the blood is moving freely and so gives the diastolic pressure.
