study tissues

study cells

atom –> molecule –> organelle –> cell –> tissue –> organ –> organisms

atom

cell // all living things are composed of cells

tissues

organelles

cells

skin, hair, and nails

hormone producing glands, such as the thyroid gland

brain, spinal cord, and nerves

spleen, red bone marrow, lymph nodes, tonsils

stimulus, sensor, control center, & effector

activate brain’s heat-gain center –> reduce blood flow to the skin –> shunt blood returning from your limbs away from the digits into a network of deep veins –> increase muscle contraction –> shiver –> generates heat –> body produces thyorid hormone and epinephrine, chemicals that promote increased metabolism and heat production

childbirth and blood clotting resulting from a penetrating wound
