Anatomy

• The study of bodily structures and their interrelationships

Physiology

• The study of bodily functions, examining how different parts of the body operate

Levels of structural organization

• Chemical level: atoms (C, H, O, N, P) and molecules (DNA)
• Cellular level: muscle cell
• Tissue level: muscle tissue
• Organ level: stomach contains the tissue
• System level: digestive apparatus
• Organismal level

Basic life processes

• Metabolism
• Reproduction
• Differentiation
• Growth
• Movement
• Response

Homeostasis

• The condition of equilibrium in the body's internal environment due to continuous interaction of many regulatory processes
• Feedback systems monitor conditions, receptors sense changes and send signals to control centers, which then send signals to effectors to cause a change

Negative feedback system

• Receptors in blood vessels detect increased blood pressure
• Sends signal to the brain, the brain interprets signals
• The heart then sends signals to blood vessels causing reduced heart rate which then lowers blood pressure
• Homeostasis is restored

Positive feedback system

• Contractions push the baby towards the cervix, causing distension
• Nerve cells in the cervix send impulses to the brain
• The brain triggers release of oxytocin, causing stronger contractions
• The cycle stops after birth

Body Cavities

• A cavity is a space or enclosure
• Cranial cavity: Formed by cranial bones, contains the brain
• Vertebral canal: Formed by vertebral column, contains spinal cord
• Thoracic cavity: Contains pleural and pericardial cavities and the mediastinum
• Pleural cavity: Surrounds each lung, serous membrane is the pleura
• Pericardial cavity: Surrounds the heart, serous membrane is the pericardium
• Mediastinum: central part of thoracic cavity, contains heart, thymus, esophagus, trachea, and large blood vessels
• Abdominopelvic cavity: subdivided into abdominal and pelvic cavities
• Abdominal cavity: contains stomach, spleen, liver, gallbladder, small intestine, and most of large intestine; serous membrane is the peritoneum
• Pelvic cavity: contains urinary bladder, portions of large intestine, and internal organs of reproduction

Thoracic Cavity

• Pleural Cavities surround the lungs
• Mediastinum contains internal anatomy

Abdominopelvic Regions

• Right hypochondriac region
• Epigastric region
• Left hypochondriac region
• Right lumbar region
• Umbilical region
• Left lumbar region
• Right iliac region
• Hypogastric region
• Left iliac region
