Water Balance Adipose tissue is one of the most hydrated of all tissues in the human body. False The most abundant cation in intracellular fluid is sodium. False Electrolytes determine most of the chemical and physical reactions of the body. True Solutes‚ regardless of size‚ are able to move freely between compartments because water carries them along the osmotic gradients.False The thirst center in the brain is located in the hypothalamus.True Dehydration can be caused by endocrine disturbances

temperature‚ and the release of 8 major hormones. The hypothalamus is inferioer to the thalamus. It is posterier to the optic chiasm and bordered on the sides by the temperal lobes. Damage to the anterior hypothalamus blocks the production of ADH. This leads to a condition where the kidney fails to conserve water‚ this is called diabetes insipidus About ten or eleven small‚ indistinct nuclei (nerve cell groups) are packed into the hypothalamus. Reflecting their complex and highly specialized

The Endocrine System: 1. What is the Endocrine System? •The Endocrine System influences almost every cell‚ organ‚ and function of our bodies. •It is a collection of glands and organs that produce and regulate hormones in the bloodstream to control many bodily functions. •Whereas the nervous system responds to and controls body processes which occur quickly and last for a short amount of time‚ the endocrine system is responsible for many of the slow

Aim: To find out if there is a relationship between fluid intake and urine output‚ by measuring my daily fluid intakes and urine outputs. Hypothesis: The volume of urine I will produce will be at least half of the volume of fluids I will drink‚ due to the body’s ability to carry out a water balance just as one would have on oxygen‚ carbon dioxide to maintain a healthy and working body. For example if I drink 1000cm3 of fluids then the expected amount of urine I should produce would be around 4000
