Lymphatic vessels are vein-like tubes connected at one end to the tiny organs known as lymph nodes, which carry the lymph (serum full of white blood cells) from the lymph node to the heart.
Lymphatic nodes are part of the Lymphatic System, which helps the Immune System fight against pathogens. Whenever you get sick with the flu or some similar virus, your lymph nodes can become swollen--this is why doctors feel the side of your throat when they check you over at an appointment! They're checking to see if your tonsils (lymph nodes in your throat) are swollen.

There isn't another name for the Lymphatic System, although the Lymphatic System is closely related to the Immune System because both fight germs. Collectively, they are called the Immunolymphatic System.
The muscles responsible for ensuring that organs function properly are called smooth muscles. These muscles are found in the walls of organs such as the stomach, intestines, and blood vessels, and help to regulate the movement and function of these organs.
A vessel that, unlike a blood vessel, carries fluid only away from tissues. This fluid is a pale, watery substance known as lymph.The smallest lymph vessels are the lymph capillaries, which begin in the tissue spaces as blind-ended sacs. Lymph capillaries are found in all regions of the body except the bone marrow, central nervous system, and tissues, such as the epidermis, that lack blood vessels. They are especially numerous in the loose connective tissues under the epithelium of the skin and mucous membranes.
There are different forms of mesenchymal cells and tissues found almost everywhere in the body, and these tissues can be thought of, broadly, as: connective tissues, blood vessels, and lymphatic vessels.Mesenchymal cells/ tissues originate from the middle embryonic germ layer (there are 3 - endoderm, mesoderm, ectoderm) called the "mesoderm" and differentiate into the body's various connective tissues found in bone, cartilage, ligaments, tendons, muscles, skin, organs, extracellular matrix, as they also form the blood vessels and lymphatic vessels.

Endothelium provides a slick, friction-reducing lining in lymphatic vessels and in all hollow organs of the cardiovascular system- blood vessels and the heart. Mesothelium is the epithelium found in serous membranes, the membranes lining the ventral body cavity and covering its organs.
Lymphatic vessels are not found in the central nervous system, including the brain and spinal cord.

Lacteals are specialized lymphatic vessels found in the intestinal villi, primarily in the small intestine. They absorb dietary fats and fat-soluble vitamins from the digested food, forming a milky fluid known as chyle. Once absorbed, chyle is transported through the lymphatic system and eventually enters the bloodstream, facilitating the distribution of nutrients throughout the body.
Lymphatic vessels contain lymph, a fluid that circulates throughout the body to maintain fluid balance, transport waste, and support immune function. The lymphatic vessels are also surrounded by lymphoid tissues, such as lymph nodes, which house immune cells that help in fighting infections and regulating immune responses.
Simple Squamous epithelial cells are found in the lung (alveoli), lining the lumen of blood vessels, and lymphatic vessels, and also in the kidneys.
