Body Cavities
What is the Cranial Cavity formed of, and what does it hold?
Formed by cranial bones and holds the brain
Organs
Name the system: Protects internal body structures; prevents fluid loss; temperature regulation
Integuemntary
Name the system: Transports materials (cells, nutrients, wastes, gases) between cells & tissues
Cardiovascular
What is homeostasis?
The ability to maintain a relatively stable internal state in spite of external environment
What is the Vertebral Cavity formed of, and what does it hold?
Formed by vertebrae and contains the spinal cord
atoms->molecules->cells->tissues->organs->organ systems
Name the system: supports and protects organs; attachments for muscles; produces blood cells
Skeletal
Name the system: Protects against foreign invaders; returns tissue fluid to bloodstream; absorb fat
Lymphatic
Explain what the Receptor, Control Center, and the Effector do
Receptor: Sensitive to a particular stimulus
Control Center: Analyzes stimulus and sends commands
Effector: Structure that carries out commands
What are the two spaces that make up the Thoracic Cavity, and what do they store?
Pericardial: Surrounds the heart
Pleural: Surrounds both lungs
How many different organ systems are there, and list at least 6 of them
Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary/Excrtory, and Reproductive
Name the system:Moves body and its parts; maintenance of posture; production of body heat
Muscular
Respiratory
Explain what the three examples of Negative Feedback are
Thermoregulation: Body temp changes
Blood Sugar Regulation: Blood glucose changes
Osmoregulation: Water retention changes
Name the 6 organs that the Abdominal Cavity stores
Liver, stomach, spleen, small intestine, & most of the large intestine
Name the system: produces gametes; passes on genetic information
Reproductive
Names the system: Controls/integrates body activities; controls high function (thought/reasoning)
Nervous
Name the system: Supplies body with substance from which energy is derived; transports wastes
Digestive
Childbirth: stretching of uterine walls
Lactation: milk production
Blood Clotting: platelets release clotting factors
Name the 3 organs that your Pelvic Cavity stores
Bladder, some of the large intestine, and reproductive organs
Name the system: Filters waste from blood; helps maintain water and electrolyte balance
Urinary/Excretory
Name the system: Produces & secretes hormones that regulates metabolism, respiration, and growth
Endocrine
