Anatomy & Physiology - LYMPHATIC SYSTEM PPT By wincy Thirumuruganthiru murugan
lymphatic system:DEFINITION:
The lymphatic system is a network of vessels and organs that regulates the amount of fluid in the human body and defends it against infections
Lymph
Lymph is a transudative fluid that is transparent and yellow. It is formed when fluid leaves the capillary bed in tissues due to hydrostatic pressure.
LYMPHATIC VESSELS :
THE TUBAL STRUCTURES CARRY THE LYMPH FLUID FROM THE TISSUE TO THE BLOOD STREAM.
TYPES OF VESSELS :
AFFERENT VS EFFERENT LYMPH VESSELS:
Lymphatic capillaries
Lymphatic capillaries are the smallest lymphatic vessels that collect the interstitial fluid from the tissues. There are also special types of lymphatic capillaries called lacteals. These capillaries absorb nutrients from the small intestine.
COMPOSITION OF THE LYMPH FLUID:
(around 95%) comprised of water.
The remaining 5% is composed of proteins, lipids, carbohydrates
VOLUME OF LYMPH : The average adult produces between 3-4 litres/ day.
Lymphatic pathway/circulation:
TYPES OF LYMPHATIC VESSELS
SUPERFICIAL AND DEEP LYMPHATIC VESSELS.
LYMPHATIC TRUNKS: The efferent vessels empty into the lymphatic trunks. There are four pairs of trunks:
Lumbar,
Bronchomediastinal,
Subclavian and
Jugular.
LYMPHATIC DUCT:
The lymphatic trunks then converge into the two lymphatic ducts; the right lymph duct and thoracic duct. Lymphatic vessels vs. blood vessels
Lymphoid organs : The Lymphoid organs are the sites where the maturation and proliferation of lymphocytes occur and help carry out various immune functions.
Types of Lymphoid Organs
1. Primary Lymphoid Organs: bone marrow and thymus 2. Secondary Lymphoid Organs: lymph nodes, spleen, tonsils, Peyer’s patches of the small intestine, and Mucosal associated lymphoid tissues (MALT). 3. Tertiary Lymphoid Organs: These organs also play a prominent role in the immune response to cancer.
The Lymphoid Organs Functions
The functions of lymphoid organs are as follows: 1. The main function of lymphoid organs is developing and providing immunity to the body. 2. The primary lymphoid organs, i.e., the bone marrow and thymus, are the sites where the proliferation and maturation of B-lymphocytes and T-lymphocytes take place. 3. Bone marrow is involved in the production of blood cells, i.e., RBCs (or erythrocytes), WBCs (or leucocytes), and Platelets (or thrombocytes). 4. The spleen helps in the removal of damaged red blood cells. In foetal conditions, this is also a haematopoietic organ. 5. Lymph nodes and spleen helps in filtering out and destroying the unwanted lymphocytes. They also help in maintaining the population of mature lymphocytes to enable the adaptive immune response to begin. 6. The tonsils prevent foreign materials and pathogens from entering the body.
Lymphocytes:
Lymphocytes are a type of WBC (leucocytes) that are the main components of our immune system.
Clinical Relevance:
lymphoma,
Lymphatic filariasis, Lymphadenopathy, Lymphedema

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Small lymphatic vessels join to form larger
Finally form two main lymph vessels:
On the Rt. side : The right lymphatic duct.
On the LT. side : The thoracic duct.
Both open in Veins in the
neck
So lymph returned to blood
stream.
