INTRODUCTION Flashcards
is the branch of biology that deals with the normal functions and activities of
living organisms and their parts.
Physiology
It focuses on understanding how various bodily systems and processes work together to
maintain life and enable the organism to adapt to its environment.
Physiology
It encompasses a wide range of topics, including the functions of organs, tissues, cells, and
molecules, as well as the mechanisms by which living organisms regulate and respond to
changes in their internal and external environments.
Physiology
Goals of Physiology (2)
- to understand and predict the
body’s responses to stimuli - to understand how the
body maintains internal
conditions within a narrow
range of values in the
presence of continually
changing internal and
external environments.
3 man components for homeostasis
- Receptor
- Control center
- Effector
Helps the body maintain a stable internal environment

Integrative
Environmental
Explores how organisms adapt to different environments, such
as extreme temperatures, high altitudes, or aquatic habitats.
Environmental Physiology
Focuses on understanding how various physiological systems
interact and collaborate to maintain overall homeostasis within an organism.
Integrative Physiology
Compares physiological processes across different species to
identify common principles and adaptations that have evolved over time.
Comparative Physiology
Investigates the processes of reproduction, including gamete
production, fertilization, pregnancy, and the hormonal regulation of reproductive functions.
Reproductive Physiology
Examines the functions of the kidneys, including filtration, reabsorption,
and secretion, as well as their role in maintaining water and electrolyte balance.
Renal Physiology
Studies the processes involved in digestion, absorption of nutrients,
and the functions of organs like the stomach, intestines, and liver.
Digestive Physiology
Focuses on the mechanics of breathing, gas exchange, and how
the respiratory system maintains the balance of oxygen and carbon dioxide in the body.
Respiratory Physiology
Explores the functions of the heart and blood vessels, including
circulation, blood pressure regulation, and the transport of nutrients and gases.
Cardiovascular Physiology
Examines the mechanics of muscle contraction, the physiology of
muscle tissues, and the role of muscles in movement.
Muscle Physiology
Studies the endocrine system and its hormones, which regulate
various physiological processes such as metabolism, growth, and reproduction.
Endocrine Physiology
Investigates the complex workings of the nervous system, including how
nerve cells transmit signals, how the brain processes information, and how the body
responds to various stimuli.
Neurophysiology
Explores the interactions between different organs to form organ
systems, such as the cardiovascular, respiratory, digestive, and nervous systems.
Systemic Physiology
Focuses on understanding how specific organs work, their structures,
and the functions they perform. This includes organs like the heart, lungs, liver, and kidneys.
Organ Physiology
Examines the functions of individual cells, including their metabolism,
energy production, and specialized processes such as cell division and signal transduction.
