What this category covers
Physiology gives medical learners the baseline language of how the body works before disease is discussed.
These terms are foundational for understanding later categories like pathology, diagnosis, and cardiology.
Featured Physiology Terms
These pages are the strongest opening set for this category and serve as the main internal links for early indexing.
Diastole
The phase of the cardiac cycle during which the heart muscle relaxes and the chambers fill with blood, comprising approximately two-thirds of the cardiac cycle duration.
Hemoglobin
A protein in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs.
Radial Pulse
The pulse palpated at the radial artery in the wrist, commonly used to assess heart rate, rhythm, and peripheral perfusion in clinical practice.
Baroreceptor
Specialized stretch-sensitive mechanoreceptors located in the carotid sinus and aortic arch that detect blood pressure changes and regulate cardiovascular homeostasis vi...
Carbon Dioxide
A colorless, odorless gas produced by cellular metabolism and eliminated via respiration, with critical roles in acid-base balance and respiratory drive regulation.
Synapse
The specialized junction between neurons or between a neuron and effector cell where neurotransmitters are released to transmit signals.
Action Potential
A rapid, temporary change in membrane potential that propagates along excitable cells (e.g., neurons, muscle cells) to transmit electrical signals.
Adaptive Immune Response
The antigen-specific immune response mediated by B cells and T cells, characterized by immunological memory, which enables a stronger and faster response upon subsequent...
Antibody
A protein produced by B cells in response to a specific antigen, capable of binding to that antigen to neutralize or mark it for destruction by the immune system.
