It is found in the wall of the collecting ducts of the nephron B. cells could be of many shapes, cubical or columnar C. The endothelial cell is a type of epithelium bounded at its outer surface by a basement membrane. D. Epithelial cell might be a secretory cell E. Skin consists of simple epithelium 21. Which of the following best describe insects circulatory system? ---------------------. A. Insects often have accessory pulsatile structures that aid hemocoel flow through their legs, wings, and antennae. B. The blood of insects lacks a respiratory pigment. C. Hemocoel is about 20-40% of body volume D. hamolymph bathes tissues directly E. all of the above are correct 22. All of the followings are correct, except--------------------------------. A. Pulmonary circuit of birds & mammals is maintained at much lower pressures than systemic circulation B. Bird embryos have mechanism to shunt of blood from one circuit to the other C. Mammals fetus has the same pressure on both sides of the heart D. In amphibians, the blood vessels draining the left and right ventricles have an interconnecting aperture E. In some fish species that have air breathing organ, the gills remain partly functional 23. All of the followings are correct about fish, except --------------------- A. Respiratory and systemic circuits of fishes are in parallel B. Gill circulation is under higher pressure than systemic circulation C. Gills play a major role in ionic regulation and gas transfer D. Heart consists of two main chambers E. The myocardium is sometimes supplied with O2 by blood flowing through a coronary circulatory system, whereas sometimes it is supplied by blood flowing through the heart lumen.
