Chapter 57, Problem 1PL
When comparing the position of the two kidneys.
a. they are at the same level.
b. the right kidney is slightly superior to the left kidney.
c. the right kidney is slightly inferior to the left kidney.
d. the right kidney is anterior to the left kidney.
Expert Solution & Answer
Summary Introduction
Introduction :
Urinary system or the excretory system is the organ system present in mammals and other animals. The main function of this system is to get rid of the toxic chemicals, especially nitrogenous waster produced by the body in various biochemical processes. The kidney is the chief organ of the excretory system.
Answer to Problem 1PL
Correct answer :
The correct answer is option (c).
Explanation of Solution
Explanation/justification for the correct answer :
Option (c) the right kidney is slightly inferior to the left kidney. The kidney is present in abdominal cavity. The right kidney lies just beneath the liver. Due to the large size of liver, it is present slightly downwards or inferior as compared to the left kidney. Hence, the correct answer is option (c).
Explanation for incorrect answer :
Option (a) they are present at same positions. The right and the left kidneys are slightly different. They are not aligned at the same position. The presence of liver above the right kidney makes is slightly inferior to the left one. So, this option is incorrect.
Option (b) right kidney is superior to the left kidney. The right kidney is slightly downwards, so, the left kidney is superior to the right one. So, option (b) is incorrect.
Option (d) the right kidney is inferior to the left kidney. The right and the left kidney are retroperitoneal in position and lie in the same plane. So, option (d) is incorrect.

Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply. Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.arrow_forward
- When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.arrow_forwardWhen taking vitamins and vitamin-mineral supplements, how can one be sure they are getting what they are taking?arrow_forwardHow many milligrams of zinc did you consume on average per day over the 3 days?
