+<p><span class="seoSummary">The <strong><code>Body</code></strong> {{glossary("mixin")}} of the <a href="/en-US/docs/Web/API/Fetch_API">Fetch API</a> represents the body of the response/request, allowing you to declare what its content type is and how it should be handled.</span></p>

+<p><code>Body</code> is implemented by both {{domxref("Request")}} and {{domxref("Response")}}. This provides these objects with an associated <dfn>body</dfn> (a <a href="/en-US/docs/Web/API/Streams_API">stream</a>), a <dfn>used flag</dfn> (initially unset), and a <dfn>MIME type</dfn> (initially the empty byte sequence).</p>

You'll notice that since we are requesting an image, we need to run {{domxref("Body.blob","Body.blob()")}} ({{domxref("Response")}} implements body) to give the response its correct MIME type.</p>
