The red pulp is composed of the splenic cord and spenic sinus. No lymph nodule and germinal center are found in spleen. The lung is a pair of long flat sac and the pulmonary alveoli are capsular. There are nodus-like enlargements in pulmonary alveolustubules. The kidney is composed of renal corpuscle, neck segment,proximal tubule, middle segment,distal tubule and collecting tubule. The renal corpuscle is composed of glomerulus and renal capsule. There are similar structures of maculae densa about renal corpuscle.
