The primary function of the digestive system is to break down food and help your body absorb the nutrients from this food. The digestive system is made up of the digestive tract‚ which includes the esophagus‚ stomach and intestines and other organs that aid in digestion such as the liver‚ pancreas and gall bladder. The breaking down of food for digestion begins in your mouth. As you eat something‚ your teeth break down the food‚ and your saliva helps to breakdown and it moistens the food so

explaining them. Phonetics According to Bruce Hayes (2009)‚ Phonetics is primarily an experimental science‚ which studies speech sounds from three viewpoints: • Production (articulatory phonetics): how sounds are made in the human vocal tract • Acoustic (phonetics): the study of the waveforms by which speech is transmitted through the atmosphere • Perception (auditory phonetics): how the incoming acoustic signal is processed to detect the sound sequence originally intended by

Jessica Wellman PHSL-P215 Paper 1 The respiratory system is protected by an innate defense system. The entire respiratory tract in lined with a mucus membrane that collects foreign particles. Once the mucus‚ or airway surface liquid (ASL) traps particles‚ mucus clearance is an essential mechanism to remove the foreign particles‚ such as dust‚ bacteria‚ viruses and other potential pathogens‚ and to keep our airways and lungs clean and free of obstruction. An important mechanism for clearing mucus

The formation of urolithiasis is a complex process which began with the formation of hard‚ crystalline mineral material that grew and got retained within the urinary tract. Urolithiasis can be form within and obstruct the renal calices or the ureter. Obstructions plus periodic peristalsis of the ureter result in

of urinary incontinence. Stress incontinence is an involuntary loss of urine that happens because of physical activity‚ like coughing‚ sneezing‚ laughing‚ or exercise. The strength of the pelvic floor muscles is inadequate to support the urinary tract under pressure. The anatomy of the urinary system involved in continence in women includes the bladder‚ urethra‚ pelvic floor muscles and sphincter. Urine is stored in the bladder which fills like a balloon to accommodate up to two cups of urine
