What are the small organs found on lymphatic vessels called?
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.
What is the composition of lymph?
Lymph is composed of water, proteins, electrolytes, fats, white blood cells, cellular debris, and sometimes microorganisms. Its composition can vary depending on the location and function within the body.
How does lymph move through the lymph vessels without a pump?
Lymph is moved through the lymph vessels by surrounding muscles contracting and relaxing, which creates pressure changes that help propel the lymph forward. Additionally, one-way valves within the lymph vessels prevent the backflow of lymph, helping to maintain the flow.
What is the difference between cephalic lymph nodes and pectoral lymph nodes?
The pectoral lymph nodes are also known as the anterior group and can be found just inferior to the pectoralis minor muscle, the cephalic nodes are also known as deltopectoral lymph nodes and they receive lymph from the superficial vessels only
Describe source of lymph and mechanism of lymph transport?
Lymph: fluid within lymphatic vessels 1. Made of water & dissolved substances (that had left blood capillaries by filtration and diffusion) 2.Includes small, dissolved proteins that had also leaked from capillaries Forces that propel lymph through lymphatic vessels: - skeletal muscle contractions - breathing movements - contraction of smooth muscle in walls of lymphatic trunks (movement similar to venous movement)

How does the composition of lymph in the cisterna chyli differ from that in the general lymphatic stream?
Composition of the lymph in the cisterna chyli has conduit for the lipid product of digestion. General Lymphatic stream gets interstitial fluids and white blood cells, and goes through lymph nodes to be cleaned before sent back to the blood vessels to be carried back to the heart. Contains FATTY lymph

LYMPH NODES
Is The structure of a lymph vessel is most similar to A capillary?
Yes, the structure of a lymph vessel is most similar to that of a capillary. Both have thin walls that allow for the exchange of fluids and small molecules. Lymph vessels feature one-way valves that prevent backflow, similar to the function of venous valves in the circulatory system. This design aids in the transport of lymph fluid back to the bloodstream, akin to how capillaries facilitate nutrient and waste exchange.
Why is it important that lymph vessels are spread throughout body?
lymph vessels are like blood vessels and they carry fluid similar in composition to blood plasma (only that they carry clear fluid containing less protein than blood plasma and numerous white blood cells which help to fight infection, especially lymphocytes), the body tissues are bathed in lymph from the blood , then the lymph vessels drain the lymph away just like the vein drains deoxygenated blood from body back to the heart, in a situation whereby the drainage of lymph by the lymph vessels is interupted, there is accumulation of fluid in that part of the body causing edema( excessive accumulation of fluid in the body) so the lymph vessels are important for drainage of lymph throughout the body and due to this they are able to carry antibodies(foreign micro organisms in the body) to the lymph node to be destroyed. all the lymph that is collected goes to the thoracic duct and right lymphatic duct which then empty back into the blood.

Is The structure of a lymph vessel is most similar to arteries or arterioles?
The structure of a lymph vessel is most similar to that of veins rather than arteries or arterioles. Lymph vessels have thinner walls, larger lumens, and valves to prevent backflow, similar to veins. In contrast, arteries and arterioles have thicker, more muscular walls to handle higher pressure from blood flow. Therefore, lymph vessels share more characteristics with veins in terms of structure and function.
What vessel does the lymph exit through?
A lymph vessel. They are similar in function to blood vessels. However the lymph is moved along the vessel by muscle contractions rather than by the heart pumping.
The mineral composition of the oceanic crust is similar to the composition of what rock?
The mineral composition of the oceanic crust is similar to the composition of basalt rock. Basalt is a type of volcanic rock that contains minerals such as feldspar, pyroxene, and olivine, which are also commonly found in the oceanic crust.
