2. Cells make tissues
Tissues make Organs
Organs make Organ
Systems
Organ Systems make an
organism

3. The Digestive System: The Respiratory System:
 Smooth muscle cells  Epithelial lung cells
make: make:
 Intestinal muscle  Epithelial lung tissues,
tissues, which make: which make:
 Intestines, which are  Lungs, which are part
part of the: of the:
 Digestive system  Respiratory system

4.  Epithelial tissue– tightly packed cells that line
organs and make the skin
 Connective Tissue—support, bind together, and
protect tissues and organs. Tendons, ligaments,
bone and cartilage are connective tissues
 Muscle Tissue—produces movement. Skeletal,
cardiac, and smooth muscle
 Nervous Tissue—transmits and receives impulses

5.  Circulatory—heart, blood vessels, blood lymph
nodes, lymphatic vessels. Transports oxygen,
nutrients, and wastes; regulates body
temperature.
 Digestive—mouth, pharynx, esophagus,
stomach, intestines, pancreas, gallbladder, liver.
Breaks down /absorbs nutrients, salts, water;
rids of waste
 Endocrine—hypothalamus, pituitary, thyroid,
parathyroid, adrenals, pancreas, ovaries, testes.
Growth, development, metabolism, maintains
homeostasis

6.  Immune—white blood cells, thymus, spleen.
Protects against disease, stores and makes white
blood cells.
 Integumentary—skin, hair, nails, sweat and oil
glands. Barrier to infection, injury, UV rays,
regulates body temperature.
 Muscular—skeletal,smooth, and cardiac
muscles. Produces movement, helps circulate
blood and moves food
 Nervous– brain, spinal cord, peripheral nerves.
Processes info., regulates responses

7.  Reproductive—testes, penis, ovaries, fallopian
tubes, uterus, vagina. Produces reproductive
cells, houses an embryo
 Respiratory—nose, sinuses, pharynx, larynx,
trachea, lings. Brings in O2, expels CO2 and
water vapor
 Skeletal—bones, cartilage, ligaments, tendons.
Supports and protects organs, movement, stores
nutrients, makes red blood cells.
 Excretory—skin, lungs, kidneys, bladder.
Eliminates waste, helps maintain homeostasis

8.  Allparts of the body are controlled by
feedback loops.
 Negative feedback keeps things at set points
(ex. body temperature, blood glucose level,
oxygen levels)
 Positive feedback moves AWAY from a set point
(ex. clotting factors will increase greatly until a
cut stops bleeding, hormones levels are greatly
increased during puberty)
