Muscular system | Movement, Maintenance of body posture, Production of heat |
Nervous system | Communication, Integration, Control, Recognition of sensory stimuli |
Endocrine system | Secretion of hormones directly into the blood, Same as nervous system- communication, integration, control, Control is slow and of long duration, Examples of hormone regulation: Growth, Metabolism, Reproduction, Fluid and electrolyte balance |
Cardiovascular (circulatory) system | Transportation, Regulation of body temperature, Immunity (body defense) |
Lymphatic system | Transportation, Immunity (body defense) |
Respiratory system | Exchange of waste gas (carbon dioxide) for oxygen in the lungs, Area of gas exchange in the lungs called alveoli, Filtration of irritants from inspired air, Regulation of acid-base balance |
Digestive system | Mechanical and chemical breakdown (digestion) of food, Absorption of nutrients, Undigested waste product that is eliminated is called feces, Appendix is a structural but not a functional part of digestive system, Inflammation of appendix is called appendi |
Urinary system | "Clearing" or cleaning blood of waste products- waste product excreted from body is called urine, Electrolyte balance, Water balance, Acid-base balance, In males, urethra has urinary and reproductive functions |
Reproductive system | Survival of genes, Production of sex cells (male: sperm; female: ova), Transfer and fertilization of sex cells, Development and birth of offspring, Nourishment of offspring, Production of sex hormones |
