Regulation of internal environment (homeostasis): WAEC Biology Past Questions and Answers
What the WAEC syllabus covers in Regulation of internal environment (homeostasis)
Our summary: How the kidney, liver and skin keep the body's internal conditions steady.
- Kidney: structure and functions (Osmoregulation, excretion and maintenance of acid-base balance should be mentioned. The conditions that affect functions of the kidney such as the water and salt content of the blood, environmental temperature should also be mentioned. Excretory products such as urea, water, salts, uric acid should be mentioned.)
- Liver: functions of the liver (Candidates should be able to identify the liver; and its position relative to the gall bladder, bile duct, pancreas, duodenum and stomach.)
- The skin: structure and function (Candidates should observe, draw and label the mammalian skin. The regulation of internal environment by the skin should be emphasized.)
