Document Summary

Pa"s e ects on the body: when a person engages in a sustained bout of pa, nearly all of the systems and organs come into play to support the activity. Video: energy systems: might ask for general characteristics, does it use oxygen, how long before depleted, atp stored in muscle to produced movement, moment that lasts longer then a few seconds the more atp needed. Cardiovascular and respiratory systems: primary functions, provide body with oxygen (o2) and nutrients, rid body of carbon dioxide (co2) and metabolic waste products, maintain body temp. and acid-base balance. Endocrine system: primary function: maintaining internal environment of the body via the release of hormones from specialized glands throughout the body important in maintaining homeostasis e ected by exercise and changes how hormones are released. Immune system: primary functions, protect the body from infection, destroy invaders to the body. Go for your first run in a while. 15-20% of blood going to muscles at rest.
