Body Changes with Age: Immune System
The immune system protects the body from infection and disease, but with age, this natural defense system can become slower and less effective. This course introduces caregivers to the anatomy and function of the immune system and how aging impacts immune responses. Learners will explore common immune system conditions such as cancer, HIV, and AIDS, and gain insight into how to support clients with compromised immunity while promoting safety, dignity, and infection control. Caregivers will also learn to recognize potential signs of immune-related illness and the importance of timely reporting. Counter with a worn label and handwritten pillbox

- Identify common immune-related conditions, including HIV and AIDS, and how the immune system is affected by diseases like cancer.
- Understand general caregiver responsibilities when supporting clients living with weakened immune systems, including infection prevention and monitoring.
- Recognize signs of potential immune system distress, such as frequent infections, weight loss, fatigue, or persistent fever—and know when to report them.
- Promote safe care practices and respect client dignity, especially when working with individuals living with HIV/AIDS and those with compromised immune systems, such as clients undergoing cancer treatment.
