Lymphatic system
The lymphatic system consists of lymph and lymphatic vessels that transport lymph throughout the body. Lymph is interstitial fluid that has entered lymphatic capillaries and contains lymphocytes, macrophages, viruses, bacteria, and cellular debris. The main components of the lymphatic system are lymph, lymphatic vessels, lymph nodes, lymphatic trunks and ducts, and lymphatic tissue. Lymph flows from lymphatic capillaries through vessels, nodes, trunks and ducts and eventually returns to the blood circulation via the subclavian veins. The lymphatic system functions to transport fluids and nutrients, support immune responses, and absorb dietary fats.
lymphatic system
The document summarizes key aspects of the lymphatic system:
1) The lymphatic system is made up of lymphatic vessels, tissue, and organs that circulate a colorless fluid called lymph throughout the body.
2) The lymphatic system contains primary and secondary lymphoid organs. Primary organs include the bone marrow and thymus where lymphocytes develop. Secondary organs include the spleen and lymph nodes where lymphocytes collect and immune responses occur.
3) Lymphocytes contain two main types of immune cells - B-cells and T-cells - as well as natural killer cells, which are subtypes of white blood cells important for immune function.
Lymph and lymphatic system
The lymphatic system consists of lymph, lymph vessels, lymph nodes, and lymphocyte-containing tissues. It collects fluid that leaks from blood vessels, known as lymph, and returns it to the circulatory system. The lymph flows through a network of thin-walled lymphatic vessels and passes through lymph nodes, which contain immune cells. Any foreign substances are filtered out before the lymph rejoins the bloodstream in larger veins in the neck.
Chapter 20: Lymphatic System
The document provides information about the lymphatic system, lymphoid organs, and tissues. It discusses how fluid filters from capillaries into the interstitial space and how the lymphatic system removes excess fluid and proteins. It describes the structure and function of lymphatic vessels, lymph nodes, and other lymphoid tissues like the spleen, thymus, tonsils, and mucosa-associated lymphoid tissue. The main roles of these tissues are to filter lymph, activate immune responses, and provide sites for immune cell proliferation and surveillance.
Lymphatic system Physiology
The lymphatic system is a closed system of lymph vessels that drains lymph fluid from tissues and returns it to the bloodstream. It consists of lymph capillaries that drain into larger vessels and ultimately form the right lymphatic duct and thoracic duct, which empty into subclavian veins. The lymphatic system helps fight pathogens through innate immunity as the first line of defense and acquired immunity developed by T and B lymphocytes, which provide cellular and humoral immunity through memory and plasma cells. Cytokines are proteins secreted by immune cells that help coordinate immune responses.

Johny's A&P The lymphatic system
The lymphatic system comprises a network of lymphatic vessels that carry lymph fluid away from tissues and toward the heart. Unlike the cardiovascular system, it is not a closed system. The main functions of the lymph system are to provide an accessory return route for fluid to the bloodstream, absorb and transport fatty acids from the intestines, and transport white blood cells between tissues and lymph nodes, where immune responses occur. The four main components are lymph fluid, lymph vessels, lymphoid tissues including lymph nodes and thymus, and immune cells like lymphocytes and phagocytes that travel through the lymphatic system.

THE LYMPHATIC SYSTEM// LYMPH CIRCULATION//LYMPH VESSELS// LYMPH ORGANS
The lymphatic system is a sub-system of circulatory system and immune system.
It is a type of drainage system of human body which collects all the tissue fluids (constantly leaking out of the bloodstream) and takes back to the major veins through a network of lymph vessels.
The lymphatic system consists of -
Lymph – colourless tissue fluid
Lymphatic organs – Thymus, Bone Marrow, Lymph nodes, Spleen, Tonsils.
Lymph vessels – through which lymph circulation takes place.
It maintains balance between blood and tissues:
Blood volume : 5 – 6L
Interstitial fluid volume: 10 – 11L
Lymph volume: 2 – 3L.
It helps in Immunity.
It fascilitate absorption of fats and hormones:
Breakdown products of fat and fat-soluble vitamins are absorbed into the central lacteals (lymphatic vessels) of the villi.
Normal blood circulation forces fluid out of the bloodstream and that leads in the increase in the interstitial fluid volume.
Due to osmotic pressure this interstitial fluid will be collected by the fine lymphatic capillaries.
Now this fluid is lymph and it has the same mineral distribution as that of blood plasma.
The lymph is transported to lymph nodes and organs where the pathogen will be killed by lymphocytes and lymph will be filtered.
The back flow of lymph is prevented by the valves present in lymph vessels.
Lymph moves from lymphatic vessels to lymphatic trunks, collecting ducts, and ultimately into the Subclavian veins.
Assessment of lymphatic system
The lymphatic system transports fluid and immune cells throughout the body, removes cellular waste and pathogens, and presents antigens to immune cells. It consists of lymphatic vessels, lymph nodes, the spleen, thymus, tonsils, and bone marrow. Lymph fluid is collected from tissues by lymphatic capillaries and passes through lymph nodes, which filter the lymph and harbor immune cells. The lymph eventually returns to the blood circulation via lymph ducts in the neck. Enlargement of lymph nodes or spleen can indicate infection, inflammation, or cancer that is being assessed through history, exam, labs, and imaging.

The lymphatic system consists of lymph, lymph vessels, lymph nodes, and lymph organs such as the spleen and thymus. Lymph is a clear fluid that transports plasma proteins from tissues back to the bloodstream and carries away debris from damaged tissues. Lymph vessels are thin-walled and valve-lined, transporting lymph towards the heart. Lymph nodes filter lymph and proliferate lymphocytes. The spleen and thymus are major lymph organs - the spleen filters blood and stores lymphocytes, while the thymus develops T-lymphocytes. Mucosa-associated lymphoid tissues such as tonsils and Peyer's patches intercept antigens from the mouth, throat, and intestines.

Lymphatic system ppt
The lymphatic system is a drainage system that works alongside the venous system to remove tissue fluid from interstitial spaces. Lymph capillaries absorb excess tissue fluid and transport it through lymphatic vessels to lymph nodes, where it is filtered. The filtered lymph then drains into either the thoracic duct or right lymphatic duct and returns to the bloodstream. The lymphatic system removes larger particles from tissues and transports mature lymphocytes throughout the body. Key components include lymph vessels, central lymphoid tissues like bone marrow and thymus, peripheral lymphoid organs like lymph nodes and spleen, and circulating lymphocytes in the bloodstream.
Lymphadenopathy approach
Lymphadenopathy refers to abnormal lymph nodes in size, number, or consistency. It can be generalized, involving two or more non-contiguous lymph node groups, or localized to a single group. Common causes include infections, cancers, autoimmune diseases, and medications. A thorough history and physical exam are important to evaluate potential causes and symptoms. Red flags suggesting possible malignancy include supraclavicular adenopathy, hard/tender nodes, matted nodes, and nodes that do not regress after 3 weeks or fever resolution. Careful assessment of lymphadenopathy guides further diagnostic workup and management.

The lymphatic system helps fight infection and disease. It is composed of lymph vessels that carry lymph fluid containing white blood cells. Lymph fluid is similar to plasma but contains larger particles like bacteria and damaged cells. Lymph vessels connect to lymph nodes which filter the lymph and contain lymphocytes that fight infection. The largest lymph vessels are the thoracic duct and right lymphatic duct which drain lymph into the bloodstream. Disorders of the lymphatic system include lymphomas, lymphadenitis, and lymphedema.
Anatomy and physiology of Lymphatic System
The lymphatic system transports a clear fluid called lymph throughout the body. Lymph is collected from tissues by lymphatic capillaries and contains white blood cells, cellular waste, and excess fluid. It is similar in composition to plasma but contains larger particles. Lymph travels through a network of lymphatic vessels and is eventually returned to the bloodstream through the thoracic duct or right lymphatic duct in the neck. Along the way, lymph passes through lymph nodes which filter the lymph and help fight infection and disease. Common diseases of the lymphatic system include lymphomas, lymphadenitis, and lymphedema.
UNIT -3 CHEPTER -2 LYMPHATIC SYSTEM.pptx
Lymph is a clear fluid that forms when blood plasma leaks out of capillaries into tissues. It is collected by lymphatic capillaries and vessels before entering lymph nodes and eventually returning to the bloodstream via the thoracic duct. The lymphatic system helps maintain fluid balance in the body, transports nutrients, and plays an important role in immunity through lymph nodes and vessels that contain lymphocytes.

The majority of the document categorizes and describes different types of cardiac arrhythmias like sinus tachycardia, sinus bradycardia, premature atrial contractions, atrial flutter, atrial fibrillation, junctional rhythm, junctional tachycardia, premature junctional contractions, and supraventricular tachycardia. For each type it discusses causes
Pelvis
The female pelvis aids in childbirth and is formed by the two innominate bones, the sacrum, and coccyx. There are four shapes of the female pelvis: gynecoid, android, anthropoid, and platypelloid. The pelvis contains four bones and several joints including the sacrococcygeal, sacroiliac, and symphysis pubis joints. The true pelvis has a brim, cavity, and outlet with specific diameters that allow for childbirth.

BPH
Benign prostatic hyperplasia (BPH) is an enlarged prostate gland most commonly seen in men over 50 years old. It involves the noncancerous increase in size of the prostate. Common symptoms include frequent urination, urgency, and weak urine stream. Diagnosis involves digital rectal exam, lab tests, and prostate-specific antigen level. Treatment options include medications like alpha blockers and 5-alpha-reductase inhibitors, or surgical procedures like transurethral resection of the prostate. Nurses help manage symptoms, prevent complications like infection, and ensure proper healing after any procedures.
Stye
A stye, also known as a hordeolum, is an infection of a sebaceous gland in the eyelid caused by staphylococcus bacteria. It results in a red, tender bump on the eyelid. Styes are commonly caused by bacterial infection, excessive cosmetic use, poor nutrition, lack of hygiene, sleep deprivation, or rubbing of the eyes. Signs and symptoms include eyelid swelling, pain, redness, tenderness, crusting, and blurred vision. Treatment involves analgesics, warm compresses, antibiotics like erythromycin ophthalmic ointment or chloramphenicol, and incision and drainage for severe cases. Prevention focuses on proper eye and hand hy

Lymphatic system
- 1. BY- ROMENA BEGUM FINAL YEAR MSC (N)
- 2. The lymphatic system consists of a fluid called lymph.This fluid is flowing through the lymphatic vessels.Lymph passes through the vessels and lymph nodes.
- 3. The entire system consists of Lymph Lymph capillaries Lymph vessels Lymph node Lymph ducts Lymph organs Lymphatic tissue Bone marrow
- 4. Tissue drainage Absorption and transportation of fat from the small intestine. Protect from infection Produce lymphocyte Produce antibody and antitoxin Transporting nutrients to tissue Keep body cell moist
- 5. •Lymph is a colourless interstitial fluid closely resemble blood plasma in composition. •Lymph is isotonic. •Normal lymph flow is 2-4 L/day(80- 150ml/hour) for entire body.
- 6. Lymph capillaries Lymphatic vessels begin as closed ended vessels called lymphatic capillaries. Lymphatic capillaries have slightly larger diameter than blood capillaries. The network of lymphatic vessels is present in all tissue except central nervous system,bones and superficial layer of skin.
- 7. The lymphatic vessels of left side unite to form a thoracic duct and right side unite to form right lymphatic duct.
- 9. Lymph nodes are small,oval or bean like bodies placed in the lymphatic vessels and joint together by them.
- 10. The main groups present in •Neck •Axilla •Thorax •Abdomen •Groin.
- 11. Each node is covered by a capsule of dense connective tissue. The capsular extensions are called trabeculae. The paranchyma of a lymph node is specialized into two region,cortex and medulla .
- 12. 1.Cervical nodes 2.Axillary nodes 3.Inguinal nodes 4.Pelvic nodes
- 14. Primary organ Secondary organ Red bone marrow & Thymus Lymph nodes,spleen & lymphatic nodules
- 15. •Thymus is a bilobed lymphatic organ. •It is located in the mediastinum. •Weight -10-15gm at birth. • Its consist of 2 lobes. •Each lobe has 2 lobules. •Each lobules consists of outer cotex n central medulla part
- 16. Thymosin hormone stimulates the maturation of thymus & lymphoid tissue. Thymus develop into activated T- Lymphocytes.
- 17. The oval spleen is the largest single mass of lymphatic tissue in the body. The anterior surface is covered with peritoneum. It measures about 12 cm long. Its weights about 200mg.

- 20. The main groups of mucosa- associated lymphoid tissue are the tonsils & peyers patches.
- 21. Lymphatic nodules are oval shaped concentrations of lymphatic tissue. The main group of mucosa-associated lymphoid tissue are the tonsils & peyers patches. •Tonsils form a ring at the junction of the oral cavity & oropharynx. •They destroy the swallowed & inhaled antigens.
- 22. These are located in the small intestine & intercept swallowed antigens.
- 23. Lymphatic capillaries(lymph) Subclavian veins (blood plasma) Lymphatic ducts Lymphatic vessels Interstitial spaces(interstitial fluid) Blood capillaries Arteries(blood plasma)
