About two-thirds of the weight of an adult human consists of water. About two-thirds of this water is located within cells, while the remaining third consists of extracellular water, mostly in the blood plasma and in the interstitial fluid that bathes the cells. This water, amounting to about five percent of body weight (about 5 L in the adult), serves as a supporting fluid for the blood cells and acts as a means of transporting chemicals between cells and the external environment. It is basically a solution of salt (NaCl) containing smaller amounts of other electrolytes, the most important of which are bicarbonate (HCO 3 – ) and protein anions.
First, I would like to say “thank you”. You have inspired me to take an extra step in my daily teaching. I am a NBCT, and still struggle with finding reading strategies worthy of what little time I gave in my classroom. Living in a rural county with over 80% of the population qualifying did free/reduced lunch, u find myself stuck in a rutt of teaching vocabulary. I use as much non-fiction texts as possible (with visuals) because my students are lacking in background knowledge. I can see me utilizing these graphic organizers in my classroom this week! Thank you for sharing your knowledge with others.
