To explain:
The role of nephron and collecting duct in controlling blood osmolarity.
Introduction
The urinary system of human is composed of paired kidneys and ureters, a urinary bladder, and a urethra. The main function of the urinary system is to produce urine and eliminate waste materials outside the body. Each human holds roughly one million microscopic nephrons in their kidney which are packed in the renal cortex. Nephrons constitute the structural and functional part of the kidney.
To determine:
The role of ADH in water reabsorption.
Concept introduction
Antidiuretic hormone maintains the blood pressure, blood volume and tissue water content by managing the amount of water. Kidney function adjusts continuously to maintain homeostasis. Hormone-like antidiuretic hormone (ADH) helps the kidney to maintain homeostasis. ADH triggers the reabsorption of more water from the distal convoluted tubules and collecting duct so the urine becomes more concentrated.
To explain:
The process by which kidneys help to control blood

To determine:
The process by which mammalian kidneys are adapted to the wet and dry environment.
Concept introduction
The kidney is an important part of the mammalian urinary system which helps in the formation of urine. The urinary system is composed of paired kidneys and ureters, a urinary bladder, and a urethra. The main function of the urinary system is to produce urine and eliminate waste materials outside the body.
To determine:
The process by which the urinary systems of freshwater and saltwater fishes differ. Give reasons.
Concept introduction
The fishes live in both freshwater and saltwater bodies. The saltwater bodies have more dissolved salt than the freshwater bodies. The fishes living in saltwater and freshwater bodies have different mechanisms of water regulation.

- a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involvedarrow_forwardIf you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F. Interval; Do not change the intervalarrow_forwardWhat percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. Show the matharrow_forward
