Skeletal system
Which system containts support & movement, main source of body heat , of posture
Muscular System
Which system contains integration and coordination of organ function through nerve impulses and neurotransmitters/ rapid-short-term effects
Nervous system
The Endocrine system is the …..
Integration and coordination of organ function through chemical messengers called hormones; slower, longer-lasting effects
The cardiovascular system is the…..
transportation of gases, nutrients, blood cells, hormones, and wastes
Which system consists the transportation of fluids from tissue spaces to blood, carries fat from digestive system to blood , and defends body against infection
Lymphatic system
The digestive system receives…..
receives food, breaks down food, absorbs digestion products, excretes waste
The respiratory system moves…..
moves air in and out of body, exchanges gases (O2 and CO2) between blood and air; absorbs oxygen
The urinary system removes…..
removes blood waste, regulates electrolytes, water balance, and blood pressure. Produces urine and excretes by transporting it outside the body
The reporductive system…..
male and female produce and transport sex cells, produce hormones, and produce new-like organisms. Females also provide for fetal development and childbirth
