which cellular process would be affected by a disease that attacks and destroys lung tissue
cellular respiration
function of large intestine
absorb water and produce feces
groups of muscles held together by
connective tissue
purpose of reflex arc
maintain homeostasis
digestive system
breaks down macromolecules to make energy
nervous system
releases nuerotransmitters to communicate between its own cells to illicit a change
circulatory system
responds to hormones to regulate body processes by either constricting or dilating to change blood flow to various organisms
skeletal system
regulates mineral homeostasis by breaking down bone to release minerals to blood as needed
respiratory system
maintains blood pH level
what will happen after a heart attack
blood will stop pumping and cells will not get oxygen and nutrients needed
why does pulse drop due to shock
vasoconstriction
negative feedback

positive feedback
encourages function
