Organization
(1) Living Organization• All living things are made of cells and
atoms/molecules.
• Levels of Organization:– Atoms and Molecules– Organelles and Cells– Tissues– Organs– Organ Systems– Organism
(2) Homeostasis• Involuntary processes and reactions are in place to
maintain Homeostasis within cells.
• Homeostasis = Internal stability / balance.
(3) Nervous System• Function:– Controls all other organ systems + homeostasis.– Allows you to respond to changes/stimuli.
• Made Up Of:– Brain– Spinal Cord– Nerves
(4) Lymphatic System• (A.K.A. The Immune System)
• Function:– Protect body against harmful infectious agents +
compounds.
• Made Up Of:– White Blood Cells– Lymph Vessels, Nodes, and Fluid
(5) Cardiovascular System• Function:– Work with the respiratory system to circulate gases.– Pump nutrients throughout the body to working
tissues.
• Made Up Of:– Heart– Blood Vessels– Blood + Blood Cells
(6) Respiratory System• Function:– Work with the cardiovascular system to circulate gases.– Bring oxygen into body + expel carbon dioxide.
• Made Up Of:– Nasal Cavity– Lungs– Diaphragm
(7) Skeletal System• Function:– Provide body support and mobility.– Protect organs.
• Made Up Of:– Bones– Joints– Cartilage
(8) Muscular System• Function:– Body + Organ mobility.– Produce body heat.
• Made Up Of:– Muscle – Ligaments + Tendons
(9) Digestive System• Function:– Break food into smaller pieces.– Metabolize biomolecules within food.– Absorb useful nutrients + expel waste.
• Made Up Of:– Oral Cavity + Esophagus– Stomach– Small + Large Intestine– Rectum + Anus
(10) Excretory System• (A.K.A. The Urinary System)
• Function:– Filter Blood.
• Made Up Of:– Kidneys– Ureters– Bladder– Urethra
(11) Reproductive System• Function:– Pass genes on to produced offspring.
• Made Up Of:– Male Sperm, Testes, Penis– Female Eggs, Ovaries + Uterus, Vagina
