The nutrition of the chondrocytes depends on the diffusion in its ECM of substances originated from blood vessels placed around cartilage pieces. Blood vessels are present in a layer of dense connective tissue that covers most cartilage pieces, called the <strong>perichondrium<\/strong> .<br \/>\nDue to this nutritional mechanism the cartilage pieces tend to be small and thin. Therefore, the distances that nutrients, metabolites, and gases must travel within the cartilage to reach the chondrocytes are short.<br \/>\nThe figure shows some examples of the distribution of cartilage tissue in the body:<\/p>\n<p>1- Articular surfaces \u2013 hyaline cartilage<br \/>\n2- Epiphyseal discs (growth zones of long bones) \u2013 hyaline cartilage<br \/>\n3- Auricles of the ear \u2013 elastic cartilage<br \/>\n4- Nose \u2013 hyaline cartilage<br \/>\n5- Epiglottis \u2013 elastic cartilage<br \/>\n6- Larynx \u2013 hyaline and elastic cartilage<br \/>\n7- Trachea \u2013 hyaline cartilage<br \/>\n8- Extrapulmonary and intrapulmonary bronchi \u2013 hyaline cartilage<\/p>\n<\/div><\/div>\n  <div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\"> <\/p>\n<p><img decoding=\"async\" src=\" https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/6-2.jpg \" \/><\/a><br \/>\n<strong><\/p>\n<p><a href=https:\/\/mol-en.icb.usp.br\/index.php\/6-3-cartilage\/\">NEXT PAGE<\/a><\/p>\n<p><a href=\"https:\/\/mol-en.icb.usp.br\/index.php\/6-1-cartilage\/\">PREVIOUS PAGE <\/a><\/p>\n<p><a href=https:\/\/mol-en.icb.usp.br\/index.php\/6-0-cartilage\/\">MENU OF THIS CHAPTER<\/a><br \/>\n<\/div><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-3015","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/3015","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/comments?post=3015"}],"version-history":[{"count":12,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/3015\/revisions"}],"predecessor-version":[{"id":20962,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/3015\/revisions\/20962"}],"wp:attachment":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/media?parent=3015"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
