  • Role of the Kidney in Fluid Balance
    Lab 7: The 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...

    STRUCTURE OF NEPHRON: Nephrons (Greek nephros=kidney) are renal or kidney tubules. Each kidney has over one million nephrons that are responsible for removing waste products from blood and maintaining water, salt and pH balance in the body. This vital job results in the formation of urine. 1.Afferent Arteriole * receives blood rich in oxygen from the renal artery. * blood is transported to the glomerulus of the nephron where it is pressure filtered. 2.Glomerulus * The...

  • Excretion and Elimination of Toxicants and Their Metabolites
    Excretion and Elimination of Toxicants and their Metabolites The first topic that was covered by this chapter was the excretion of wastes by the Renal system. The first step that occurs in the kidney deals with the nephron, which is the functional unit of the kidney. In the glomerulus the formation of urine begins with the passive filtration of plasma through the pores that are found in the glomerulus. The plasma is forced through these pores by hydrostatic pressure. The only things that...

  • Glomerular Filtration - 259 Words
    The anatomy of the kidneys consists of two bean-shaped organs behind the peritoneum in the lower back and are covered by an outer, tough capsule. Function Inside the kidney is divided into an outer cortex and medulla. Urine production begins in the cortex and then flows steadily through to the calyxes, a cup shaped organ or cavity. The urine collects in the renal pelvis and then moves down the ureter to the urinary bladder. Sphincters retain urine in the bladder. With relaxation of the...

  • The Rule of Three - 1629 Words
    ` Project 3.4.3: The Blood/Urine Connection Introduction Water is obtained from food, drink, and from reactions that occur in the body. The kidneys process and balance the amount of water that enters your system with the amount that is released. The digestive system helps rid the body of solid wastes, but some of the wastes in the blood are the remnants of the digestion of food products. For example, when amino acids are broken down by the body, ammonia (NH3) is formed. This product is...

    Case Study: Urinary, Fluid & Electrolyte balance The cardiovascular system and the urinary system are intimately entwined. When the cardiovascular system experiences stress, the urinary system can be directly impacted. For example in hemorrhagic shock, when the body is rapidly depleted of circulating blood volume, the kidneys are often one of the first vital organs affected due to lack of perfusion. The kidneys are dependent on the sufficient cardiac output that the heart delivers. So when...

    Blood Water Homeostasis or Osmoregulation Osmoregulation is the process by which the body regulated the osmotic pressure of any organism’s fluids in order to keep the homeostasis of the organisms’ water level constant. Therefore osmoregulation is used to keep the bodily fluid from being too diluted or too concentrated. An osmotic pressure is used to measure the ability of water to move from one solution to another solution through osmosis. Osmotic pressure refers to tendency for a liquid...

    Homeostasis is the maintenance of a steady state. With changes within and around living cells, conditions are maintained at a constant level. The ‘two major control systems, nerves and hormones, are mainly responsible for co-ordinating homeostatic mechanisms’ (Human Body) whilst using feedback. If a change in condition is detected a corrective mechanism is activated, conditions return to set point and the corrective mechanism is then switched off. The conditions are then at constant level. Some...
