Question

please i need your help with this question. thanks

The micrographs in this document are from a cross-section of the small intestine. This image is part of the field of view using a 10X eyepiece and a 4X objective, providing a total magnification of 40X. The digital camera image here is approximately 2/3 of the visual field of view, giving an actual magnification of about 60X. What tissues are visible here? For a closer look, change the size of the field of view in the Word toolbars A DI D2 B D3 D4 C Image 1 Image 1 The image is a picture of a cross-section ofthe intestinal wall. From the exterior (top of the picture) to the intermal surface (bottom) are four different layers. Layer D1 is the Layer D2 is the Layer D3 is the ), and layer D4 is the . The thin tissue covering the exterior of the structure at letter A is Nearly all of the tissue which is found in layer D2 consists off.Layer D3 is made primarily of )but also contains blood vessels, nerves and lymphatic vessels. Layer D4 consists of tissue C, which is Remember that you are (D1) to the interior surface (C, D4) working from the outside of the intestine D1 D2C D3C D4) Image 2 This is a higher magnification view of part of the slide shown in the first image above.E1 and E2 together form the.

(L ) The tissue at E5 contains many collagen and elastin fibers produced by cells called ( ) .It is ( )or (). A close look at E6 (Zoom to 300% on the Word version) shows what look like layers of block-like cells. That suggests that the tissue is ), a tissue that associated with lar secretions (Brunner's nds in this case)

Answer 1

ANSWER :

1) The layer D1 in the given figure of the small intestine is serosa (outermost layer). Layer D2, D3 and D4 are muscularis (circular & longitudinal), submucosa and mucosa respectively.

The thin tissue covering the exterior of the structure is serosa. Nearly all the tissues found in the layer D2 are musclular connective tissue. The layer D3 is primarily of digestive glands but also contains nerves, blood vessels and lymphatic vessels. The layer D4 (mucosa) consists of epithelial tissue.
