5 body cavities and what they hold
Cranial: holds the brain
Vertebral: house the spinal cord
Thoracic: contains the heart and lungs
Abdominal: digestive organs
Pelvic: bladder and reproductive organs
Three types of passive transport
Diffusion, osmosis, facilitated diffusion
Anatomy of a long bone (2 main sections) and what marrow they have

Demonstrate 3 different body planes
Sagittal (medial from lateral)
Transverse (inferior from superior)
Coronal/Frontal (anterior from posterior)
4 phases
1. Prophase (where loose nuclear DNA condenses into distinct, visible chromosomes
2. Metaphase (duplicated chromosomes condense and align along the center of the cell)
3. Anaphase (chromosomes separate and move toward opposite poles of the cell)
4. Telophase (the cell reverses the structural changes of prophase to re-establish normal cell organization before division)
Vertebrae number in the human body. How many in each section?
24 vertebrae, 7 cervical, 12 thoracic, 5 lumbar
