The <strong>heart apex<\/strong>, located at the bottom, points downward and to the left, which helps to determine anatomical orientation.<\/p>\n\n\n\n<p>The <strong>right and left sides<\/strong> of the heart can be distinguished by the direction of the apex and the location of the large vessels. The <strong>right side<\/strong> (seen on the left in the image) includes the <strong>pulmonary trunk<\/strong>, which branches to send deoxygenated blood to the lungs. The <strong>left side<\/strong> (on the right of the image) includes the <strong>aorta<\/strong>, the thick-walled artery that distributes oxygenated blood to the body.<\/p>\n\n\n\n<p>At the top, <strong>auricles<\/strong> (or appendages) of the atria are visible; these ear-like flaps increase the capacity of the atria. Their wrinkled appearance makes them distinguishable from the smoother surface of the ventricles.<\/p>\n\n\n\n<p>Structures like the <strong>vena cava<\/strong>, <strong>pulmonary veins<\/strong>, and internal chambers (atria and ventricles), as well as valves such as the <strong>tricuspid<\/strong>, <strong>bicuspid<\/strong>, and <strong>chordae tendineae<\/strong>, are found internally or on the posterior and thus are not visible from this angle. Dissecting the heart or rotating it to a posterior view would reveal those features.<\/p>\n\n\n\n<p>Understanding the orientation and surface features of the heart is vital for dissecting and identifying structures accurately. This anterior view forms the basis for exploring internal anatomy and understanding blood flow through the heart.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/05\/learnexams-banner6-151.jpeg\" alt=\"\" class=\"wp-image-221877\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Label the following photos: Sheep Heart Dissection Anterior View: Right side of the heart Left side of the heart Right and left auricles (appendages) Apex Pulmonary trunk Aorta Posterior View: interventricular sulcus Pulmonary veins Vena cava Interior View: Left atrium Left ventricle Right atrium Right ventricle Interventricular septum Bicuspid valve Tricuspid valve Chordae tendineae Papillary [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[25],"tags":[],"class_list":["post-221875","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/221875","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=221875"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/221875\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=221875"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=221875"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=221875"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
