Document Summary
Alveoli (lungs) , glomeruli (kidney), serosa (inner layer in cavities) Stratified squamous going through constant division (deep down) Two kinds of stratified squamous: keratinized, nonkeratinized. Other types of stratified: cuboidal, columnar (not many examples) Most complex and diverse of tissue types. Fewest cells on average, and most packed with fibrous proteins and ground substance. Main functions: binds organs together: tendons muscle to bone, ligaments bone to bone. Support: bones support body, cartilage supports other structures. Macrophages: larges phagocyte which can carry out phagocytosis- engulf and destroy foreign material and dead/dying cells. Adipocytes are often scattered, not concentrated- store triglycerides. Collagen: can only bend a little bit: found deeper in skin. Reticular: thin, more fragile, coated with glycoprotein structures: tend to form sponge like shape (not feeling) Elastic: stretch, thinner than collagen: can tolerate stretch and recoil back, because of protein elastin. The most gel like in fibrous connective tissue.
