VNSG 1320 Anatomy and Physiology

Explore the foundations of human anatomy as we break down bone structure, the skeleton, and how our bodies heal and move. Test your knowledge with interactive pause-and-answer checks covering everything from osteocytes to spinal vertebrae.

Trace the journey of a single breath from the upper airway deep into the lungs to explore the vital differences between breathing and oxygenating. Learn the essential mechanics of pressure gradients, respiratory anatomy, and the four key steps of respiration with active-recall study stops along the way.

Explore the essential components of human blood as we break down plasma, erythrocytes, leukocytes, and platelets. Learn how to interpret key Complete Blood Count (CBC) markers and master clinical concepts like hemostasis and the shift to the left.

Explore the body's primary communication networks as we break down the fundamental differences between nervous and endocrine signaling. Learn the anatomy of neurons, the vital support roles of neuroglia, and how these systems work together to maintain homeostasis.

Explore the anatomy and physiology of the renal system, from the microscopic filtration inside nephrons to hormonal regulation by the RAAS pathway. Learn key clinical takeaways for nursing, including urine output benchmarks and fluid-electrolyte balance.

This episode breaks down the body from atoms to organ systems, clarifying the difference between anatomy and physiology and why directional terms matter in clinical practice. It also explores electrolytes, water, metabolism, and the narrow pH range that keeps cells and enzymes functioning.
