Human physiology is the study of the normal function of body organs and tissues. Body organs that certified nurse assistants study during their training include the skeletal, muscle, skin, nervous, cardiovascular, respiratory, digestive, renal, and endocrine systems, and the role of these organ systems. A basic understanding of how the normal body maintains a stable internal environment and efficient organ system functioning is important in order to recognize the physical stresses that disrupt organ system stability, such as acute and chronic medical problems, diseases, infections. It is also important for all health professionals to know normal human body functions and processes that must adjust to physical variants and environmental stressors or imbalances affecting human health.
After completing this inservice, the learner will be able to:
- Describe how the human body maintains an optimal internal environment through homeostasis by way of feedback loops.
- State the different organ systems of the human body and their functions.
- Describe how the separate organs of the human renal system function normally to eliminate body waste in urine.
