23a: The priest and the levite
23b: (from wikipedia) "<em>In Jewish culture, </em><em>contact with a dead body </em><em>was understood to be </em><em>defiling.</em><em> Priests were particularly enjoined to </em><em>avoid uncleanness.</em><em> The priest and Levite may therefore have </em><em>assumed</em><em> that the fallen </em><em>traveler was dead </em><em>and avoided him to </em><em>keep themselves ritually clean."</em>
23c: He took care of himand helped the wounded traveler to recover.

Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
