- The next layer after the mucosa is called the submucosa. This layer is a thick layer of loose connective tissue. Although this layer does not have any sub-layers, it does have blood vessels, vessels belonging to the lymphatic system, and nerves, some of which control digestion.In some places, such as the small intestine, the submucosa also contains cells that secrete mucus onto the surface of the tract.After the submucosa is a layer called the muscularis externa. Except for the upper portion of the esophagus, this layer consists of smooth muscle.n some places, such as the small intestine, the submucosa also contains cells that secrete mucus onto the surface of the tract.

What type of muscle tissue lines the digestive system organs? Answers. 1  Smooth muscle lines hollow organs, blood vessels, glands, etc. In the gut, there is a circular layer of smooth muscle (for mixing food and enzymes and digestive juices together) and a longitudinal layer of smooth muscle (for propelling food along). Skeletal muscle is attached to bones, or to the body surface (some facial muscles).

Lymphatic system The lymphatic system is part of the circulatory system and a vital part of the immune system, comprising a network of lymphatic vessels that carry a clear fluid called lymph (from Latin lympha meaning water) directionally towards the heart.ymphocytes are concentrated in the lymph nodes. The spleen and the thymus are also lymphoid organs of the immune system. The tonsils are lymphoid organs that are also associated with the digestive system. Lymphoid tissues contain lymphocytes, and also contain other types of cells for support.

Digestion This is not considered a separate layer from the mucosa, but it does have some distinct properties. This layer is made up of connective tissue that contains blood vessels, nerves and lymphatics, vessels that carry lymph material. Absorption into the blood stream takes place in this layer.

Difference Between Yield and Return Difference Between Yield and Return. Yield and return look similar but they are different. Most of the people think the two terms to be one and the same. When talking of return, it is what an investor has earned on his investment during a certain period of time during the past.

LYMPHATIC SYSTEM AND IMMUNITY. The Lymphatic System | Back to Top. The lymphatic system is composed of lymph vessels, lymph nodes, and organs. The functions of this system include the absorbtion of excess fluid and its return to the blood stream, absorption of fat (in the villi of the small intestine) and the immune system function. Lymph vessels are closely associated with the circulatory system vessels. Larger lymph vessels are similar to veins.

Can I Rollover My SEP IRA? The IRS allows you to roll over money from your SEP IRA into a range of retirement accounts, including traditional IRAs, Roth IRAs, 401(k)s, 403(b)s and even other SEP IRAs.he Internal Revenue Service rules allow you to withdraw the money from your SEP IRA at any time -- your employer can't require you to keep it in the company plan. However, there are a few limits on when you can rollover your SEP IRA and which accounts you can roll the money into.

Introduction to the Stomach  (Digestive System) Layer of smooth muscle fibres-the innermost layer of muscle surrounds the inner-layers of the stomach and is prominent in the fundus area. Submucosa. The submucosa is a layer of areolar loose connective tissue that contains blood vessels, lymphatic vessels, and nerves). The upper (which may also be called the  superior ) part of the stomach extends, and is connected to, the oesophagus. 2  The lower (which may also be called the  inferior ) part of the stomach is connected to the duodenum, which is the first part of the small intestines.

The Lymphatic System A special set of lymphatic capillaries called lacteals transports absorbed fat from the small intestine to the blood stream. Lacteals are so-called because of the milky white lymph that drains through them. This fatty lymph, called chyle drains from the fingerlike villi of the intestinal mucosa.

Small intestine Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface. The epithelial cells of the villi transport nutrients from the lumen of the intestine into these capillaries (amino acids and carbohydrates) and lacteals (lipids).he small intestine has three distinct regions – the duodenum, jejunum, and ileum. It receives bile and pancreatic juice through the pancreatic duct, controlled by the sphincter of Oddi. The primary function of the small intestine is the absorption of nutrients and minerals from food.

- Types of Tissue. Edit 0 5 …. Types of Tissue. The digestive system contains all four major tissue types, Epithelial, Connective, Muscle and Nervous. Epithelial tissue lines the entire length the digestive tract. It is made up of many different types of cells, including goblet cells that secrete mucus.There are layers of smooth muscle that line the walls of the tract, and contract to move food through.Nervous tissue is located in the tract, and transports electrical stimulus to the brain.ypes of Tissue.

The Lymphatic System The lymphatic system is a network of very small tubes (or vessels) that drain lymph fluid from all over the body. The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils.The heart, lungs, intestines, liver, and skin also contain lymphatic tissue.he lymphatic system plays an integral role in the immune functions of the body. It is the first line of defense against disease. This network of vessels and nodes transports and filters lymph fluid containing antibodies and lymphocytes (good) and bacteria (bad).

Human digestive system The stomach is the only organ in the digestive system to have three muscle layers. The rest of the gastrointestinal tract, or GI tract, contains only two muscle layers.The muscles together as a group, are called the muscularis externa.1  muscle layer 1: outer longitudinal layer-Below this longitudinal muscle is the Auerbach's plexus, or myenteric plexus, above the middle circular. 2  It is a layer of nerves which cause peristalsis, movement of the muscle itself.his gastric illustration depicts the three layers of smooth muscle which line the stomach wall. Smooth muscle in the stomach contracts during digestion, in order to break down nutrients.

The mucosal lining of the entire digestive tract consists of stratified squamous epithelium.

General Structure of the Digestive System The mucosa, or mucous membrane layer, is the innermost tunic of the wall. It lines the lumen of the digestive tract. The mucosa consists of epithelium, an underlying loose connective tissue layer called lamina propria, and a thin layer of smooth muscle called the muscularis mucosa.In certain regions, the mucosa develops folds that increase the surface area. Certain cells in the mucosa secrete mucus, digestive enzymes, and hormones.Ducts from other glands pass through the mucosa to the lumen. In the mouth and anus, where thickness for protection against abrasion is needed, the epithelium is stratified squamous tissue.ertain cells in the mucosa secrete mucus, digestive enzymes, and hormones.

- The next layer down is the dermis (say: DUR-mis). You can't see your dermis because it's hidden under your epidermis. The dermis contains nerve endings, blood vessels, oil glands, and sweat glands. It also contains collagen and elastin, which are tough and stretchy. The nerve endings in your dermis tell you how things feel when you touch them.
