The lymphatic system consists of lymph fluid, vessels called lymphatics, and lymphatic organs and tissues. Lymphatics originate as lymph capillaries that drain fluid from tissues and transport it through larger vessels to two main channels - the right lymphatic duct and thoracic duct - which empty into veins near the heart. Lymphatic organs include lymph nodes along lymphatic vessels, the spleen, thymus gland, and tonsils. These structures filter lymph, produce lymphocytes, and mount immune responses against pathogens.
Lymph is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to the central circulation.

The lymphatic system is part of the immune system. It also maintains fluid balance and plays a role in absorbing fats and fat-soluble nutrients.
The lymphatic or lymph system involves an extensive network of vessels that passes through almost all our tissues to allow for the movement of a fluid called lymph. Lymph circulates through the body in a similar way to blood.
There are about 600 lymph nodes in the body. These nodes swell in response to infection, due to a build-up of lymph fluid, bacteria, or other organisms and immune system cells.
A person with a throat infection, for example, may feel that their "glands" are swollen. Swollen glands can be felt especially under the jaw, in the armpits, or in the groin area. These are, in fact, not glands but lymph nodes.
The lymphatic system is a part of the circulatory system, comprising a network of conduits called lymphatic vessels that carry a clear fluid called lymph unidirectionally toward the heart.
The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.

Since the lymphatic system does not have a heart to pump it, its upward movement depends on the motions of the muscle and joint pumps.

Fast facts about the lymphatic system
The lymphatic system plays a key role in immunity, fluid balance, and absorption of fats and fat-soluble nutrients.
The lymph nodes swell in response to infection, due to a build-up of lymph fluid, bacteria, or other organisms and immune system cells.
If lymph nodes remain swollen, if they are hard and rubbery, and if there are other symptoms, you should see a doctor.
The lymphatic system has three main functions:
It maintains the balance of fluid between the blood and tissues, known as fluid homeostasis.
It forms part of the body's immune system and helps defend against bacteria and other intruders.
It facilitates absorption of fats and fat-soluble nutrients in the digestive system.
BLOOD PLASMA
The lymphatic system consists of lymph vessels, ducts, nodes, and other tissues.
Around 2 liters of fluid leak from the cardiovascular system into body tissues every day. The lymphatic system is a network of vessels that collect these fluids, or lymph. Lymph is a clear fluid that is derived from blood plasma.
The lymph vessels form a network of branches that reach most of the body's tissues. They work in a similar way to the blood vessels.
The lymph vessels work with the veins to return fluid from the tissues.
The lymph vessels work with the veins to return fluid from the tissues.
Unlike blood, the lymphatic fluid is not pumped but squeezed through the vessels when we use our muscles.
Lymph is drained progressively towards larger vessels until it reaches the two main channels, the lymphatic ducts in our trunk.
In the lymph nodes, immune cells assess for foreign material, such as bacteria, viruses, or fungus.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2. Introduction
– Components
• Lymph is the fluid
• Vessels – lymphatics
• Structures & organs
– Functions
• Return tissue fluid to the bloodstream
• Transport fats from the digestive tract to the
bloodstream
• Surveillance & defense
4. Lymphatics
– Originate as lymph capillaries
– Capillaries unite to form larger vessels
• Resemble veins in structure
• Connect to lymph nodes at various intervals
– Lymphatics ultimately deliver lymph into 2 main
channels
• Right lymphatic duct
– Drains right side of head & neck, right arm, right thorax
– Empties into the right subclavian vein
• Thoracic duct
– Drains the rest of the body
– Empties into the left subclavian vein
13. Tonsils
– Multiple groups of large lymphatic nodules
– Location – mucous membrane of the oral and
pharyngeal cavities
– Palatine tonsils
• Posterior-lateral walls of the oropharynx
– Pharyngeal tonsil
• Posterior wall of nasopharynx
– Lingual tonsils
• Base of tongue
15. Spleen
– Largest lymphatic organ
– Located between the stomach & diaphragm
– Structure is similar to a node
• Capsule present
• But no afferent vessels or sinuses
– Histology
• Red pulp contains all the components of circulating blood
• White pulp is similar to lymphatic nodules
– Functions
• Filters blood
• Stores blood
17. Thymus Gland
– Location – behind the sternum in the
mediastinum
– The capsule divides it into 2 lobes
– Development
• Infant – conspicuous
• Puberty – maximum size
• Maturity – decreases in size
– Function
• Differentiation and maturation of T cells
19. Function of the Lymphatic
System
– Defense against harmful organisms and chemicals
– 2 types of defense
• Nonspecific
• Specific
– Specific defense = immunity
• Humoral immunity involves B cells that become plasma cells
which produce antibodies that bind with specific antigens.
• Cell-mediated immunity involves T cells that directly destroy
foreign cells
