Fluid * Digestive Secretions Intracellular Fluid (ICF) – This is the fluid that is contained within the cell. In adults it is approximately 2/3’s of the body’s fluid (27 liters). The ICF also known as “cellular soup” is comprised mostly of potassium‚ organic anions‚ proteins and other small cations and anions. Note: The 60-40-20 rule is that in total 60% of our body weight is water with 40% of that being intracellular with the remaining 20% being extracellular. Factors That Affect Movement

in many more ways too. Let us look at the benefits of eating this fruit. 1. It helps regulate blood pressure. Banana is a fruit that contains high amount of potassium and low levels of salt. This combination helps to regulate the blood pressure. It reduces the risk of heart related diseases. 2. It strengthens your bones. The potassium content in bananas is good for the health of your bones. Eating bananas on a regular basis can prevent your bones from deteriorating. Consuming bananas can also

Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become

ASSIGNMENT # 1 1. Adam Smith‚ 77 years of age‚ is a male patient who was admitted from a nursing home to the intensive care unit with septic shock secondary to urosepsis. The patient has a Foley catheter in place from the nursing home with cloudy greenish‚ yellow-colored urine with sediments. The nurse removes the catheter after obtaining a urine culture and replaces it with a condom catheter attached to a drainage bag since the patient has a history of urinary and bowel incontinence. The patient

The Lipid Barrier of the Cell Membrane‚ and Cell Membrane Transport Proteins The structure of the membrane covering the outside of every cell of the body is discussed in Chapter 2 and illustrated in Figures 2–3 and 4–2.This membrane consists almost entirely of a lipid bilayer‚ but it also contains large numbers of protein molecules in the lipid‚ many of which penetrate all the way through the membrane‚ as shown in Figure 4–2. The lipid bilayer is not miscible with either the extracellular
