Epithelial tissue has free surfaces, which faces either a body fluid or the outside environment and thus, provides a covering or a lining for some part of body. It is found on a lining of small intestine and helps in secretion and absorption.
The body cavity of earthworm is the true coelom, being lined by coelomic epithelium. The coelom contains coelomic fluid secreted by the coelomic epithelium. The coelomic fluid oozes out via dorsal pores to keep the skin moist which helps in respiration.

During embryonic and foetal life, blood cells are formed in yolk sac, liver, spleen, thymus gland, lymph nodes and bone marrow. In adults, red bone marrow is responsible for producing red blood cells, granular leucocytes and platelets.
Ciliated epithelium lines the inside of the oviducts, ventricles of the brain, the spinal canal as well as the respiratory passages like trachea, bronchi and bronchioles.
Frog contains thyroid gland liver, pancreas but salivary gland not found in frog’s body. It is present in humans.
Frog exhibit sexual dimorphism. Male frog can be distinguished by the presence of sound producing vocal sacs and also a copulatory pad on the first digit of the forelimbs which are absent in the female frogs.
