Dr. Jim Davis hosts Pulse of Physiology, a education show with 83 episodes published.
Explains the stages of labor and the hormonal regulation of childbirth and breastfeeding. Discusses the role of oxytocin and prostaglandins in labor, and prolactin and oxytocin in milk production and ejection.
Follows the journey from sperm-egg fusion through blastocyst formation and implantation. Highlights the role of hCG, the formation of the placenta, and key hormones like progesterone, estrogen, and hCG in sustaining preg
Covers the menstrual, proliferative, and secretory phases of the uterine cycle. Describes how estrogen and progesterone prepare the endometrium for implantation and how their withdrawal leads to menstruation when pregnan
Explores the development and maturation of ovarian follicles through the follicular and luteal phases. Emphasizes the roles of FSH, LH, estrogen, progesterone, and inhibin, and explains how hormonal feedback regulates ov
Details the process of sperm development, distinguishing between spermatogenesis and spermiogenesis. Explains the roles of Sertoli and Leydig cells and describes how FSH, LH, testosterone, and inhibin regulate sperm prod
Provides an introduction to the male and female reproductive systems, outlines homologous structures, and summarizes the functions of key reproductive hormones, including GnRH, FSH, LH, testosterone, estrogen, progestero
Focuses on how the enteric nervous system (ENS), autonomic input, and digestive hormones like gastrin, secretin, and CCK regulate motility and secretion during the cephalic, gastric, and intestinal phases of digestion.
Breaks down the chemical digestion of carbohydrates, proteins, and fats. Introduces digestive enzymes and their sources, the role of hydrochloric acid, and how bile salts aid fat digestion. Wraps up with the role of the
Explores how food moves through the GI tract using peristalsis, segmentation, mixing waves, and mass movement. Discusses how factors like chyme composition and volume influence gastric emptying, and how neural and hormon
Covers the six major functions of the digestive system—ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Differentiates between GI tract structures and accessory organs, and exp
Apply your knowledge to diagnose and interpret acid-base imbalances using arterial blood gas (ABG) values. Differentiate between respiratory and metabolic acidosis or alkalosis, and determine whether compensation has occ
Understand how the respiratory and urinary systems compensate for acid-base disturbances. Learn how the body responds to respiratory or metabolic acidosis and alkalosis, and the time course of each compensatory mechanism
Learn the basics of pH regulation, including the roles of acids, bases, and buffers. Get introduced to the bicarbonate, phosphate, and protein buffer systems, and why maintaining a stable pH is essential for enzyme and c
Discover how the cardiovascular, endocrine, and urinary systems respond to dehydration or hemorrhage to restore blood volume and pressure. Compare how the body responds to osmolar vs. isotonic disturbances.
Explore how aldosterone regulates potassium levels and how parathyroid hormone (PTH) maintains calcium balance. Learn the causes and effects of hyperkalemia, hypokalemia, hypercalcemia, and hypocalcemia, and why they mat
Understand how the body regulates osmolarity through osmoreceptors, ADH release, and thirst mechanisms. Explore how water gain and loss affect osmolarity and how the body restores balance during dehydration or fluid over
Break down how total body water is distributed between the intracellular fluid (ICF) and extracellular fluid (ECF) compartments. Learn about solute concentrations, fluid movement, and the importance of maintaining fluid
Explore how the sympathetic nervous system, RAAS, ADH, and natriuretic peptides regulate GFR in response to systemic blood pressure and volume changes, ensuring whole-body fluid and pressure homeostasis.
Understand how the kidneys regulate their own filtration rate using the myogenic mechanism and tubuloglomerular feedback, maintaining stable GFR despite changes in blood pressure.
Learn how GFR is calculated using Starling forces, how arteriole diameter affects filtration, and why GFR is a key measure of kidney function and fluid balance.
