Fluid and Electrolytes Imbalances Fluid Compartments: * Extracellular Fluid (ECF) – This is fluid found outside of the cells and the amount of ECF decreases with age. In the newborn for example‚ approximately ½ of the body fluid is contained in the ECF. By the time the infant has reached one year old; the ECF has decreased to approximately 1/3 of the total volume. In an average 70 kg adult the ECF is approximately 15 liters of total volume. ECF can further be divided into the following:

The Psychology of Collecting By Mark B. McKinley (OH) Everybody is a Collector Everybody collects something! Whether it be photographs of a person‟s vacation‚ ticket stubs from ballgames‚ souvenirs of trips‚ pictures of one‟s children‚ athletes‟ trophies‚ kids report cards‚ and those who collect “junk” (pack-rats) and dispose of it in garage sales. The Evolution of Collecting On the more formal side of “collecting‚” it does seem that growing up as “kids‚” we all collected something we made into

Sperm starts within the testis‚ in which it then passes into the epididymis and sits until it matures in the few days that it had waited. Then‚ the sperm is forced up into the ducts (vas deferens) into the seminal tubule and into the ejaculatory ducts‚ which moves semen into the urethra. Once that occurs‚ the semen covers the sperm and it moves into

Planning Aim: - to investigate the effects of different concentrations of alcohol on the membrane structure of a beetroot a) Decide what you think will be the effect of alcohol on beetroot cell surface membranes and how this will affect their permeability. Write down your idea as a hypothesis that you can test‚ and support your idea with biological knowledge. Hypothesis “The greater the concentration of the alcohol the more red pigments (betalains) move into the solution.” Biological knowledge:

Preview of Main Points: First we will take a look at the household uses of duct tape‚ then we will go over its uses in the automotive and racing world‚ finally we will go into how it has found its way into modern art. Body Main Idea 1: Duct tape gets its name from being used on ventilation shafts known as DUCTS. Although this was

Kidney’s Role in Fluid Balance Introduction The renal system performs a vital role in homeostasis. The kidneys’ ability to retain valuable constituents and expel metabolic wastes from the body enables this system to regulate the volume‚ osmolarity‚ and pH of body’s internal fluid environment (Sherwood‚ 2007‚ p. 511). The functional unit of the kidney‚ referred to as the nephron‚ is composed of both tubular components—Bowman’s capsule proximal tubule‚ loop of Henle‚ the distal tubule‚ and the collecting

P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which
