Epithelial, muscle, connective, And nervous.
epithelial covers the body surface, connective tissues support and protect (serve many functions) the nervous tissues receive stimuli while alsoconduction to and from all over the body, lastly muscle tissues.
muscles tissue consist of three types :/
skeletal, smooth and cardiac. skeletal muscle is use to help contract the skeleto., the cardiac muscle is found within the heart, and the smooth muscle is found in the walls of internal organs and blood vessels
hope this helped.
<span>The juxtaglomerular apparatus is a structure (formed by the distal convoluted tubule and the glomerular afferent arteriole) with the function in the regulation of blood pressure and the filtration rate of the glomerulus. Its primary components are:

If the inner lining of the air sacs neither thin nor highly vascularized, then it can be inferred that AIR SACS ARE CANNOT BE THE SITES OF GASEOUS EXCHANGE BETWEEN AIR AND BLOOD. Air sacs are generally lined with mucus and surrounded with blood capillaries.
In case of birds, air sacs play an important role in respiratory system.
