8 Integrated Regulation of Body Systems

Learn how body systems coordinate feedback responses to regulate internal conditions during exercise, stress, dehydration, eating, and fasting.
Study guide · Updated

7 The Digestive System

Follow how food is mechanically and chemically digested, moved through the gastrointestinal tract, absorbed, and regulated by coordinated secretions.
Study guide · Updated

2 The Nervous System

Learn how nervous tissue detects and processes information, how neurons communicate, and how the nervous system coordinates sensory input, movement, reflexes, and body regulation.
Study guide · Updated

6 The Renal System

Learn how kidney structure supports urine formation, fluid and electrolyte balance, blood-pressure regulation, and acid–base control.
Study guide · Updated

5 The Respiratory System

Learn how ventilation, gas exchange, gas transport, and breathing control work together to supply oxygen, remove carbon dioxide, and support homeostasis.
Study guide · Updated

4 The Cardiovascular System

Learn how blood, the heart, and blood vessels transport materials, circulate blood, and regulate flow to help maintain homeostasis.
Study guide · Updated

3 The Endocrine System

Learn how hormones signal to target cells, how endocrine organs regulate body functions, and how feedback coordinates growth, metabolism, blood glucose, and reproduction.
Study guide · Updated

1 Homeostasis and Principles of Human Physiology

Learn how the body regulates its internal environment, how feedback systems respond to change, and how physiological systems work together to support cellular function.
