Blood & Endocrine System Joshua Topacio Paul Lim Noelani Noriega Justin Amador Per. 2 What is this system and what is its purpose? • Control system of ductless glands that secrete hormones within specific organs • Hormones act as “messengers” and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them. • Controls height, weight, growth, maturation, adaptation to stress, sexual response, reproduction, aging, and maintains homeostasis • Without it, there would be no regulation • Hormones released into the extracellular areas to the bloodstream, and then to the rest of the body. Erythrocytes (red blood cells) • Their job is to transport oxygen • Makes up 40-50% of total blood • Red because of oxygenation • The average lifespan of a red blood cell is 4 months Leukocytes (White blood cells) • Produced in bone marrow just like red blood cells. Also produced in thymus gland • They get rid of dead or dying blood cells and foreign matter like dust • Makes up a small part of bloods volume (1%) • Life span is about 18-36 hours Thrombocytes (Platelets) • A blood cell that clogs small ruptures • Cell fragments (no nuclei) plazma • Its purpose is to carry blood throughout the body • Made of water sugar, salt solution, and fat • Accounts for about of 55% of bloods volume Hematopoiesis • Hematopoiesis: The formation of blood cells • Begins in red bone marrow with hematopoietic stem cells. When the stem cells commits it will become a red blood cell. • Our body makes about two million red blood cells every second. Cell counting • Cell counting is used to determine a persons health. • A hemocytometer is the tool most used. • It can be used to determine how quickly a pathogen is growing or to prepare for the correct amount of medicine. Erythropoiesis • Erythropoiesis: the process in which erythrocytes (RBCs) are produced. - stimulated by decreased oxygen in circulation. - detected by kidneys. - secrete erythropoietin hormone. Erythropoiesis (cont.) • Erythropoietin: hormone that stimulates proliferation & differentiation of red cell precursors. It controls the rate of RBC formation. - activate increased erythropoiesis in the hematopoietic tissue . - Hematopoietic Tissue: blood-forming tissue, consisting of reticular fibers & cells. Clotting components and Mechanisms • Coagulation: causes formation of a blood clot by a series of reactions (chain reaction) Clotting components and Mechanisms (cont.) • Release of biochemicals from broken vessels/ tissues Extrinsic Clotting Mechanism • Blood contact with foreign surfaces Intrinsic Clotting Mechanism Clotting components and Mechanisms (cont.) • Extrinsic Clotting • Tissues and Calcium • Intrinsic Clotting • Vascular System and platelets Clotting components and Mechanisms (cont.) • Prevention: Endothelium, heparin- secreting cells (liver & lungs), alpha globulin • Fibrin threads grab onto or absorb thrombin when a clot is forming. The bindings are also a prevention. Structure of Hormones • Chemistry • Range: Steroid to nonsteroids and everything in between • All organic Steroid hormones • Cholesterol is the base • Things attached to cholesterol differentiate Nonsteroid Hormones • Amines • Exs. Norepinephrine and epinephrine • From amino acid tyrosine Nonsteroid Hormones • Protein hormones Nonsteroid Hormones • Glycoproteins • From anterior pituitary glands Nonsteroid Hormones • Posterior pituitary gland and hypothalamus Hormones Activity • Must bind to a receptor • Up regulation / down regulation Steroid Hormones and Thyroid hormones • Weakly bind to plasma proteins Nonsteroid Hormones bonding nd 2 Common messengers • Cyclic adenosine monophosphate Common 2nd messenger effects • Alter membrane permeability • Activate enzymes • Promote synthesis of certain proteins • Stimulate or inhibit metabolic pathways • Promote cellular movement • Initiate hormone secretion or other PROSTAGLANDINS • Paracrine substances • Powerful but rarely used Can regulate cellular responses to hormones can stop adenylate cyclase Effects: Relax smooth muscle to smooth pathways, contractions, influence sodium concentrations, regulate blood pressure, affect reproductive physiology, inflame PITUITARY Gland • Releases from hypothalamus Pituitary gland (cont.) • Anterior pituitary hormones • Growth hormone • Controlled by somatostatin • Prolactin • Female: Promotes breast development and milk production • Male: decreases LH Pituitary gland (cont.) • Thyroid-stimulating hormone (TSH) • Controls secretion of hormones from thyroid gland • Thyrotropin-releasing hormone regulates Pituitary gland (cont.) • Adrenacorticotropic hormone (ACTH) • Controls adrenal cortex hormones Pituitary gland (cont.) • Follicle-stimulating hormone and luteinizing hormones are gonadotropins (affecting reproductive organs) Pituitary gland (cont.) • Posterior pituitary hormones • Hormones from hypothalamus • ANTIDIURETIC HORMONE (ADH) • Causes kidneys to keep in water • Oxycotin (OT) • Antidiuretic effect and contracts uterine wall muscles Thyroid gland • In neck • Follicle cells secrete • Thyroxine and triiodothyronine • Increases metabolism rate, enhance protein synthesis, and stimulate lipid breakdown. • Calcitonin • Lowers blood calcium and phosphate ion concentrations (regulate calcium) • Parathyroid hormone • Reviewed from skeletal unit Adrenal Glands Adrenal Glands • Medulla: Epinephrine and norepinephrine • Increase heart rate, muscle contraction, elevate blood pressure, increase breathing rate, decrease digestive activity Cortex: • Aldosterone saves sodium and excretes potassium • Helps maintain blood volume and pressure • Cortisol • Stops protein synthesis, releases fatty acids, and stimulates glucose production from noncarbs Adrenal Glands • Sex hormones • Supplement sex hormones of gonads Pancreas • Islets of langerhans • Secretes: • Glucagon: stimulates liver to make glucose and break fat down • Insulin stimulates glucose storage, and protein synthesis, and stimulate fat storage • Somatostatin inhibits insulin and glucagon Pineal Gland • Melatonin inhibits secretion of gonadotropins Thymus gland • Thymosin is for immunity Other glands of organs • Organs of other systems (cardio, digestive) also have glands • REPRODUCTIVE • Placenta: Estrogen, progesterone, gonadotropin • Ovaries: Estrogen, progesterone • Testes secrete testosterone Other glands of organs • Situated at linings of stomach and small intestine • Liver: IGF for immediate growth • Heart secretes atrial artriuretic peptide hormone • kidneys secrete erythropoietein Control of Secretions • Half-life • Control Sources • Hepcidin • Blocks iron to hinder viruses using it • Thrombopoietin (TPO) • Bone marrow differntiates into megakaryocytes to platelets for clotting Control of Secretions • Angiotensinogen precedes angiotensin to handle blood pressure • All of these sense hormone concentration, hormonal process, or an action hormone has on internal environment Control of Secretions • Hypothalamus controls anterior pituitary gland’s release of tropic hormone • Nervous system keeps the hypothalamus updated Control of Secretions • Positive and negative feedback Blood TYping • Definition • A classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells ABO Blood group System Phenotype • Most important bloodgroup system in humanblood transfusion • Based on 2 genes, one from each parent Genotype A AA or AO B BB or BO AB AB O OO • Found on surface of red blood cells Rh Blood group system • Second most significant blood-group system in human-blood transfusion • Also found on surface of red blood cells • Consists of 50 defined bloodgroup antigens, among which the five antigens D, C, c, E, and e are most important • Commonly used terms Rh factor, Rh positive, and Rh negative refer to D antigen • People who have the Rh factor are Rh-positive, and those that don’t are Rh negative compatability • ABO incompatibility occurs when people receive a different blood type • Rh incompatibility occurs when Rh-negative people receive Rh-positive blood • Pregnancy Works cited • About.com.
