Summary Introduction
Introduction:
Excretion is the method by which the metabolic waste products of the body are removed from the body of the organism. The major excretory organ in vertebrates is a pair of kidneys. Excretion is a crucial process in all life forms.

B)osmoregulate without using a transport epithelium for this purpose.
C)drink seawater and secrete excess ions through their kidneys only.
D)drink seawater and secrete excess ions mainly through their nasal salt glands.
E)have plasma that is isoosmotic to ocean water.
Which type of animals consume little or no energy in maintaining water balance?A. Birds B. Mammals C. Marine vertebrates D. Marine invertebrates The following are involved in the regulation of mammalian kidney function except:A. ADH B. Aldosterone C. Renin D. Oxygen
Why 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.

- State the implication of a high value of NPN in blood and urine. What does the amount of urea, ammonia, and creatinine in the urine tell us about renal function? Which food substances can lead to an increased value of NPN in the blood?arrow_forwardA fish swims from a body of cool water into a body of warm water. As its body temperature rises, its rate of O2 consumption increases. The warm water, however is likely to have a lower concentration of dissolved O2 than the cool water because the solubility of O2 in water decreases as temperature increases. These two factors taken together, an increase in the fish's rate of O2 consumption and a decrease in the dissolved O2 concentration of its environmental water, can make it difficult for the fish to obtain enough O2 to meet its needs. The two factors can act as a two-pronged trap. Actually, however, the fish may face a three-pronged trap. How is the increase in temperature likely to affect the O2 affinity of the fish's hemoglobin, and how could the effect on hemoglobin add even further to the challenge the fish faces? Does global warming pose concerns of this sort?arrow_forwardGlucose molecules are fully reabsorbed in the proximal tubule that normally, zero amount of glucose cam be found in the urine. However, a patient's urinalysis report revealed that a significant amount of glucose is found in the patient's urine sample. Based on this information, what do you think is the underlying medical condition of the patient which resulted in this report? Based on the concepts you have learned from above, what do you think is the main explanation for the presence of glucose in the urine?arrow_forward
- To keep the proper concentrations of water and solutes in their blood, freshwater bony fish must drinka. lots of water and excrete large volumes of urine that are hypotonic to body fluids.b. no water and excrete large volumes of urine that are hypotonic to body fluids.c. lots of water and excrete large volumes of urine that are isotonic to body fluids.d. no water and excrete large volumes of urine that are isotonic to body fluids.arrow_forward-For these reasons, reptiles, birds and insects expend energy and convert ammonia to uric acid which is insoluble in water and forms a white precipitate. Amphibians, such as the frog, are aquatic as juveniles and terrestrial as adults. How do you think this affects the nitrogenous waste produced by these organisms?arrow_forwardMany types of fishes live in freshwater. Generally, water moves by osmosis from the surrounding fresh water into the fish's body. This observation helps to explain which feature of the excretory systems of freshwater fishes? a. They tend to produce dilute, watery urine. b. They tend to produce concentrated, dark urine. c. They do not produce urine, but instead conserve or re-use nitrogenous wastes. d. They may produce either dilute or concentrated urine, depending on the activity of the fish.arrow_forward
- With regard to thermoregulation in humans, what could be considered an accurate consequence of the outside temperature dropping below the lower critical temperature? A. The individual will begin to breathe in less oxygen and exhale less carbon dioxide. B. The metabolic needs of the individual will increase if they remain below the lower critical temperature for sufficient time-frames. C. Capillaries (i.e. blood vessels) near the surface of the skin will dilate in order to allow blood to circulate more freely throughout the organism, distributing heat to raise temperature. D. The person's Basal Metabolic Rate will be lowered to match the Standard Metabolic Rate of an ectotherm of comparable size. E. Hormones from the hypothalamus will be released, which lead to the initiation of a positive feedback response that amplifies muscle contraction, leading to shivering.arrow_forwardWhen our tissues are burning metabolic fuel they produce protons and carbon dioxide. The enzyme carbonic anhydrase uses water to convert most of the carbon dioxide into carbonic acid. i) Describe the change of the blood carbon dioxide concentration of the swimmer from Phase I to the end of Phase II (do NOT explain the other phases)? ii) How does this change in the blood carbon dioxide concentration impact the pH of the blood of the swimmer from Phase I to the end of Phase II (do NOT explain the other phases)? iii) explain the chemical reasoning behind the impact on pH from Phase I to the end of Phase II (do NOT explain the other phases).arrow_forwardTopic:Excretion in animals Explain the roles of the lungs, kidneys and skin in the excretion of metabolic wastes in a representative mammal, human species.arrow_forward
- Some animals living in water excrete nitrogen as ammonia. Land animals, which must conserve water, excrete urea or uric acid. How does excretion of these molecules aid in water conservation?arrow_forwardRenal Physiology (humans) a) When blood pressure declines, granular cells produce renin, an enzyme that enters the circulatory system and cleaves angiotensinogen. b) Aldosterone acts on cells of the collecting duct to cause both sodium reabsorption into blood and potassium secretion into urine. c) The production of excess aldosterone by an adrenal tumor would indirectly lead to the hyperpolarization of excitable cardiac cells. d) Both (a) and (b) are correct and (c) is incorrect e) Statements (a), (b) and (c) are all correctarrow_forwardOne advantage of the excretion of urea instead of uric acid isthat ureaa. requires less energy than uric acid to produce.b. can be concentrated to a greater extent.c. is not a toxic substance.d. requires no water to excrete.e. is a larger molecule.arrow_forward
