Study Notes
Blood Composition and Function
- Blood is composed of plasma and formed elements
- Plasma: water, proteins (albumin, globulins, fibrinogen), electrolytes, gases, nutrients, waste products. Functions in transport, regulation, and protection.
- Formed elements: erythrocytes (red blood cells), leukocytes (white blood cells), platelets
- Erythrocytes: transport oxygen and carbon dioxide via hemoglobin
- Leukocytes: granulocytes (neutrophils, eosinophils, basophils), and agranulocytes (lymphocytes, monocytes); involved in immune response and inflammation.
- Platelets: essential for blood clotting.
- Blood disorders: anemia (iron-deficiency, pernicious, sickle cell), polycythemia, hemophilia, leukemias (ALL, CLL, AML, CML)
Blood Circulation and Homeostasis
- Systemic circulation: blood flow to the body
- Pulmonary circulation: blood flow to the lungs
- Blood flow regulation: maintains adequate blood supply to tissues
- Blood pressure regulation: maintains a healthy blood pressure.
- Blood volume and osmolarity: affected by electrolytes and proteins; crucial for homeostasis
- Water balance: vital for maintaining overall homeostasis
Blood Groups and Transfusions
- ABO blood group system
- Rh factor
- Blood compatibility: necessary to prevent transfusion reactions.
- Rh incompatibility in pregnancy: can cause complications for the fetus.
Hematopoiesis
- Red bone marrow: site of blood cell production
- Stem cells: precursor cells for all blood cells
- Erythropoietin: regulates red blood cell production.
Blood Clotting
- Coagulation process: involves platelets and clotting factors.
- Blood clotting disorders (hemophilia): deficiency in clotting factors can cause excessive bleeding.
Blood Disorders
- Anemia: deficiency of red blood cells or hemoglobin; leading to fatigue, weakness
- Polycythemia: abnormally high number of red blood cells, leading to blood viscosity increases.
- Hemophilia: bleeding disorder due to lack of clotting factors.
- Leukemias: cancers of the blood and bone marrow, cause abnormal white blood cell production
Heart Anatomy and Physiology
- Heart structure: pericardium (fibrous and serous), heart wall (epicardium, myocardium, endocardium), four chambers (two atria, two ventricles), heart valves (atrioventricular and semilunar valves)
- Cardiac cycle: systole (contraction), diastole (relaxation)
- Cardiac output: amount of blood pumped per minute.
- Electrical conduction system: SA node (pacemaker), AV node, Bundle of His and Purkinje fibers
- Blood vessels: arteries, veins, capillaries.
Kidney Function and Nephron Structure
- Kidney function: excretion of wastes, fluid and electrolyte balance regulation, acid-base balance regulation, hormone production (renin, erythropoietin)
- Nephron structure: renal corpuscle (glomerulus, Bowman's capsule), renal tubule (proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct)
- Renal processes: glomerular filtration, tubular reabsorption, tubular secretion
- Urine concentration: countercurrent multiplier system (loop of Henle), ADH regulation
- Renal blood flow: afferent and efferent arterioles, peritubular capillaries, vasa recta
Hormones Affecting Renal Function
- Antidiuretic hormone (ADH): regulates water reabsorption.
- Aldosterone: regulates sodium and potassium balance.
- Atrial natriuretic peptide (ANP): lowers blood pressure and blood volume.
- Parathyroid hormone (PTH): regulates calcium levels.
- Renin-angiotensin-aldosterone system (RAAS): regulates blood pressure
Male Reproductive System
- Sex determination: Y chromosome, TDF gene
- Descent of testes: into scrotum
- Scrotum: maintains temperature
- Testes: produce sperm and testosterone
- Seminiferous tubules: sperm production
- Interstitial cells: testosterone production
- Epididymis: sperm storage
- Vas Deferens: sperm transport
- Accessory glands (seminal vesicles, prostate, bulbourethral glands): produce seminal fluid
- Hormonal regulation: hypothalamic-pituitary-gonadal axis (GnRH, LH, FSH, testosterone)
- Spermatogenesis: process of sperm production
- Sperm structure and function
- Semen composition and ejaculation
Female Reproductive System
- Ovarian cycle: follicular phase (FSH, estrogen), ovulation (LH), luteal phase (corpus luteum, progesterone)
- Uterine cycle: menstrual phase, proliferative phase, secretory phase
- Hormonal regulation: hypothalamic-pituitary-ovarian axis (GnRH, FSH, LH, estrogen, progesterone)
- Fertilization and implantation: zygote formation, blastocyst implantation, hCG production
- Pregnancy and lactation: placenta function, hormone regulation during pregnancy, lactation
