Chapter 11.1, Problem 3CYP
Summary Introduction
To analyze:
The effect on homeostasis, if the kidneys are not able to excrete
Introduction:
The kidneys are the major excretory organs of the body. It is a bean-shaped and fist-sized organ that lies in the lower back of the body. A nephron is the histological and functional unit of the kidney. It is a tube-like structure with enlarged terminal ends. It includes Bowman’s capsule, proximal tubules, a loop of Henle and distal tubules. It plays a pivotal role in several homeostatic processes, including the reabsorption of sodium chloride and potassium secretion.

- e The excretory system regulates the volume and composition of body fluids by removing wastes and returning useful substances to the body. Some of the characteristics of the excretory organs are given below. 1. Carries urine to the bladder 2. Stores urine 3. Eliminates urine from the body 4. Composed of nephrons Put the numbers of the above characteristics in order, so they correspond to the urinary bladder, the ureters, the kidneys, and the urethra. (Your answer should look like 1234, but that isn't the right order.) Answer: Next page OFarrow_forwardPredict what could occur to overall homeostasis if the kidneys could notexcrete metabolic waste products from the body.arrow_forwardConsider the homeostatic imbalance of fluid such as decrease in blood volume caused by excessive blood loss. Describe how the Cardiovascular, Respiratory, Renal and Behavioral systems work to compensate for this imbalance.arrow_forward
- The breakdown of nucleic acids produces very small molecules of uric acid. Extremely high levels of uric acid built up in the joints indicate that there is something wrong with the individual's kidneys. Using the knowledge you gained from the homeostasis unit, support the connection between built up of uric acid and the possibilities of kidneys malfunctioning.arrow_forwardPredict the types of problems that would occur in the body if the urinary system could not maintain homeostasis.arrow_forwardExplain what the main product of the kidneys is.arrow_forward
- Draw a schematic diagram showing the flow of water and salts in the proximal tubule of the kidney. In this diagram, put the lumen on the left side of the diagram and the extracellular fluids on the right side of the diagram. Indicate where the lumen is, where the extracellular fluid is, where the apical portion of the cell is, and show the location of the proteins that are responsible for the movement of water and salts and glucose reabsorption in this area of the kidneyarrow_forwardVasopressin is a hormone that is mainly released when the body lacks water. The release of vasopressin causes the kidneys to conserve water by concentrating urine and decreasing urine output. However, vasopressin also has additional functions in other tissues such as the brain and blood vessels, which are not directly involved in urine production. How might vasopressin trigger different responses in different tissues?arrow_forwardDrinking seawater cannot prevent death by dehydration. What would result if humans attempted to alleviate their dehydration by drinking seawater? justify your answer by describing kidney physiology. why wouldn't reflexes, in response to dehydration, fully compensate and what does this illustrate about the force allowing kidneys to retain water under nromal conditions?arrow_forward
- Define these terms as they relate to the function of a nephron and/or kidney. - filtration - reabsoption - secretion - excretionarrow_forward+ 1. Summarize the role of the kidneys in each of the following functions: Adjusting blood volume (and so blood pressure) and the volume of interstitial fluid and lymph Regulating calcium ion levels Stimulating the production of red blood cells (erythropoiesis) Regulating blood pressure Regulating blood glucose levels Adjusting the pH of body fluids Regulating the blood Na* and K levels Regulating blood Cl levels Getting rid of wastes such as urea, ammonia, uric acid, creatinine, urobilin from breakdown of hemoglobin, foreign substances such as drugs and environmental toxinsarrow_forwardWhy are humans not able to meet their water requirements by drinking seawater? Assume seawater has a concentration of 1400 mOsM. In your explanation, consider both the renal system and the digestive system. Additionally, describe the physiology of two symptoms of excessive seawater consumption that occur prior to death.arrow_forward
