What is the most abundant cation in the ICF?
A. K+
K+: Potassium (K+) is the most abundant cation in the intracellular fluid (ICF). This is the correct answer.
B. Ca 2+
Ca2+: Calcium (Ca2+) is not the most abundant cation in the ICF; it is found in lower concentrations within cells compared to potassium.
C. Cl-
Cl-: Chloride (Cl-) is the most abundant anion in the extracellular fluid (ECF), not in the intracellular fluid.
D. Na
Na: Sodium (Na) is the most abundant cation in the extracellular fluid (ECF), not in the intracellular fluid.

Blood plasma is filtered in the____________.
A. renal corpuscle
Renal corpuscle: Blood plasma is filtered in the renal corpuscle, which includes the glomerulus and Bowman's capsule.
B. renal capsule
Renal capsule: The renal capsule is the outer protective layer of the kidney and does not filter blood plasma.
C. renal tubule
Renal tubule: The renal tubule is involved in reabsorption and secretion, not in the initial filtration of blood plasma.
D. renal column
Renal column: The renal column is a structural part of the kidney, not involved in filtering blood plasma.

Which of the following nutrients is absorbed by the lacteals of the small intestine?
A. Minerals
Minerals are absorbed directly into the bloodstream, not through lacteals.
B. Glucose
Glucose is absorbed directly into the bloodstream through capillaries, not through lacteals.
C. Amino acids
Amino acids are absorbed into the bloodstream through capillaries, not through lacteals.
D. Triglycerides
Triglycerides are absorbed by the lacteals in the small intestine. Lacteals are lymphatic vessels that transport absorbed lipids (including triglycerides) from the digestive tract.
