Study Notes
Introduction to Physiology
- Physiology is the study of how living organisms function.
- It encompasses a wide range of processes, from cellular function to organismal-level interactions.
- It focuses on mechanisms and how various systems of the body work together.
- Physiology explores the structure-function relationships within organisms, examining how anatomy influences function.
Cellular Physiology
- Focuses on the fundamental processes within cells.
- Includes topics such as:
- Membrane transport (passive and active).
- Cellular signaling.
- Metabolism.
- Cellular respiration.
- Protein synthesis.
Nervous System Physiology
- Examines the function of the nervous system in coordinating bodily activities.
- Covers topics such as:
- Neuronal communication (action potentials, synapses).
- Sensory perception.
- Motor control.
- Reflex arcs.
- Brain function.
Cardiovascular Physiology
- Studies the function of the heart, blood vessels, and blood.
- Includes topics such as:
- Cardiac cycle.
- Blood pressure regulation.
- Blood flow.
- Blood composition.
- Cardiovascular disease
Respiratory Physiology
- Focuses on the process of gas exchange.
- Explores topics including:
- Pulmonary ventilation (breathing).
- Gas transport in the blood.
- Regulation of breathing.
- Lung volumes and capacities.
- Respiratory system diseases.
Renal Physiology
- Examines kidney function in regulating fluid and electrolyte balance in the body.
- Covers topics such as:
- Glomerular filtration.
- Tubular reabsorption.
- Tubular secretion.
- Urine formation and excretion.
- Acid-base balance.
Endocrinology
- Studies hormones and their effects on various bodily functions.
- Focuses on:
- Hormone production and secretion.
- Hormone transport.
- Hormone receptors.
- Hormone effects on target cells.
Gastrointestinal Physiology
- Examines the function of the digestive system, including digestion and absorption of nutrients.
- Discusses topics such as:
- Digestion of carbohydrates, proteins and fats.
- Absorption of nutrients.
- Motility of the gastrointestinal tract.
- Secretion of digestive enzymes.
Immune System Physiology
- Studies the body's defense mechanisms against pathogens.
- Focuses on the interactions of:
- Immune cells (leukocytes).
- Antibodies.
- Immune response pathways.
- Immunological disorders.
Homeostasis
- The maintenance of a stable internal environment.
- Key to proper physiological function.
- Uses feedback mechanisms to regulate bodily processes.
- Maintaining temperature, pH, and fluid balance are examples.
Muscle Physiology
- Investigates the contractile properties of muscles.
- Covers different muscle types: skeletal, smooth, cardiac.
- Explores topics such as:
- Muscle contraction mechanisms.
- Muscle fibers.
- Muscle fatigue.
