Dear student,
Simple squamous epithelium is found in the alveoli of lungs.
There are three different types of muscle tissues present in animals:
Striated or skeletal muscles: These appear as striated fibres under microscope with alternate light and dark bands. These are voluntary muscles, which means that they are under our control and can be moved according to our will. Example: muscles of leg, hand
Smooth muscles: These are unstriated, do not have light and dark bands. These are involuntary muscles, hence cannot be moved according to our will. Example: Muscles of internal organs like stomach.
Cardiac muscles: These are striated muscles which are found only in heart. They function throughout life and relax and contract the heart the pump blood throughout body.
