6 levels of structural organization
Chemical cellular tissue organ system organism
cells
Basic structural and functional unit of life
tissues
groups of cells that work together to perform a similar function
organs
several different types of tissues that work together to perform a specific function
11 systems
digestive system respiratory system reproductive system muscular system nervous system skeletal system Integumentary System Endocrine System Cardiovascular System Lymphatic System Urinary System
Integumentary System
Skin and associated structures, such as hair, fingernails and toenails, sweat glands, and oil glands. even protects body
muscular system
skeletal muscles
nervous system
brain, spinal cord, nerves, and sensory system
Endocrine system
hormone- producing cells and glands
cardiovascular system
heart, blood, and blood vessels
Lymphatic system
lymphatic organs, lymphatic fluid, lymph nodes,
and leukocytes
respiratory system
upper and lower respiratory tracts, the trachea, bronchi, and the lungs
digestive system
Gastrointestinal tract and accessory organs
Urinary system
kidneys, ureters , bladder, and urethra.
reproductive system
ovaries, uterus and vagina in the female
testes and penis in the male
Define the 6 important life processes of the human body.
metabolism, responsiveness, movement, growth, Differentiation, reproduction
Homeostasis
the maintenance of relatively stable conditions in the body’s internal environment. it responds to changing conditions
external
outside the body
internal
inside the body
Intracellular Fluid (ICF)
fluids inside the cells
extracellular fluid (ECF)
fluids outside the cell
Interstitial fluid
between cells and tissues
blood plasma
ECF within blood vessels
lymph
ECF within lymphatic vessels
The feedback system
- Receptor which monitors the change.
- control center which Sets range, evaluates change, and generates output. Basically, try to find a solution for the change
- Effector, which receives output from the control center then produces the response
Negative feedback
usual response
stabilizing
Response is in opposite direction of stimulus
example: blood pressure, heart rate, blood sugar
Positive feedback
generally not normal
could be harmful
Response is in same direction as stimulus
Example: Shock, hypertension. Labor during birth
