🫀 Fundamentals of Physiology

Circulatory System

Study the heart, blood vessels, and blood circulation, including cardiac cycle, blood pressure regulation, and oxygen transport throughout the body.

CO = HR × SV (cardiac output)
BP = CO × TPR (blood pressure)

Respiratory System

Explore the lungs, breathing mechanisms, gas exchange, and respiratory regulation, including oxygen uptake and carbon dioxide elimination.

VO₂ = (CaO₂ - CvO₂) × CO (oxygen consumption)
VE = VT × RR (minute ventilation)

Nervous System

Investigate the brain, spinal cord, and peripheral nerves, including neural transmission, reflex arcs, and central nervous system function.

V = V₀ + Σ(wᵢ × xᵢ) (neural potential)
I = g × (V - E) (ionic current)

🔬 Advanced Concepts

Homeostasis

Study the maintenance of stable internal conditions, including temperature regulation, pH balance, and metabolic control mechanisms.

❓ Frequently Asked Questions

1. What is physiology and why is it important?
Physiology is the study of how living organisms function, including the mechanisms that maintain life and enable adaptation to changing environments.
2. How does the circulatory system work?
The circulatory system pumps blood through the body, delivering oxygen and nutrients to cells while removing waste products and carbon dioxide.
3. What is homeostasis and how is it maintained?
Homeostasis is the maintenance of stable internal conditions through feedback mechanisms that detect changes and initiate corrective responses.
4. How does the respiratory system function?
The respiratory system exchanges gases between the body and environment, taking in oxygen and eliminating carbon dioxide through breathing.
5. What role does the nervous system play?
The nervous system coordinates body functions, processes sensory information, and controls voluntary and involuntary responses to stimuli.
6. How do hormones regulate body functions?
Hormones are chemical messengers that travel through the bloodstream to target cells, regulating various physiological processes and maintaining homeostasis.
7. What is the importance of exercise for physiology?
Exercise improves cardiovascular health, strengthens muscles, enhances respiratory function, and promotes overall physiological well-being.
8. How does aging affect physiology?
Aging leads to gradual decline in organ function, reduced homeostatic capacity, and increased susceptibility to disease and injury.
9. What is the relationship between physiology and disease?
Understanding normal physiology helps identify disease mechanisms and develop treatments that restore or improve physiological function.
10. How can we maintain optimal physiological health?
Optimal health is maintained through proper nutrition, regular exercise, adequate sleep, stress management, and avoiding harmful substances.
