Cells to Organ Systems
Disease:
Types of Nutrition
Carbohydrates (sugar and starch) Main source of ENERGY for life processes
Fat (oils, butter, cream) Building material for the Cell Membrane, a reserve energy source
Protein (meat, eggs, milk, beans, fish) Repairs and maintains body tissues, supplies Amino Acids to make new cells
Vitamins (A, B, C, D, K) Lack of vitamins causes disease, vitamins are needed for a healthy body
Minerals (calcium, iron, potassium) Regulate body functions, needed for structure of body parts, maintain health
Water (water = H2O) Dissolves and transports materials in the body (body = 70% water), needed for chemical reactions in the body

Human Body Systems:
HUMAN BODY SYSTEMS AND THIER KEY WORD FUNCTIONS:
muscular: move/ locomotion
respiratory: breathing/taking in oxygen
skeletal: bones that protect and support the body
reproductive: to produce offspring (sperm + egg)
excretory: remove liquid (urine + sweat) and gaseous waste (Carbon dioxide)
digestion: break down food for nutrient
nervous: respond to the environment (sends impulse)
endocrine: produce hormones in glands
circulatory: moves nutrients and gases to and from cells

Interaction among the Body Systems: (each system does NOT work alone- their function effects other body systems)
Plants
Green plants carry out life functions in important structures such as roots, stems, leaves, and flowers.
ROOTS- absorb water & nutrients from soil; anchor plant to the ground STEM- transports water & nutrients from roots to leaves; transports food made in leaves to the rest of the plant body LEAF- gas exchange & photosynthesis take place Chlorophyll is a pigment that absorbs light energy. Chlorophyll is found inside the chloroplasts.
|
Photosynthesis occurs in the chloroplasts, located in the leaves
