Study Notes
Anatomy
- Focuses on the structure of the body
- Includes the names and locations of body parts
- Involves the study of cells, tissues, organs, and organ systems
Physiology
- Describes the body's functions
- Explains how the body works
- Emphasizes the mechanisms used to perform functions
Human Physiology in Pharmacy
- Plays a crucial role in understanding drug actions
- Helps pharmacists to explain how drugs work in the body
Cardiovascular Physiology
- Studies the functions of the heart and blood vessels
- Explores how the heart pumps blood throughout the body
Physiological Mechanisms
- Aim to maintain a stable internal environment, known as homeostasis
Negative Feedback Loops
- Integrating center receives information from the body.
- It compares current conditions to the set point.
- It sends out signals to effectors to restore balance.
Antagonistic Effectors
- Counteract each other's effects to fine-tune the response
- Ensure precise and controlled adjustments within the body
Autoregulation
- Involves communication within an organ
- Cells within the organ signal each other
- The signaling allows for specific responses to maintain organ function
Positive Feedback in Blood Clotting
- Amplifies the initial stimulus
- Leads to the formation of a blood clot, stopping bleeding
Negative Feedback Loops and Homeostasis
- Most often maintain homeostasis
- Help to stabilize internal conditions
- Prevent extreme fluctuations
Antagonistic Reactions and Homeostasis
- Occur when opposing effectors regulate a variable
- Help ensure stability and balance within the body
Positive Feedback in Many Cases
- Intensify the initial stimulus
- May lead to a rapid and significant change
Positive Feedback in Childbirth
- The strength of uterine contractions during childbirth is an example of positive feedback
- A baby pressing on the cervix triggers the release of oxytocin, which intensifies contractions
Negative Feedback Loops and End Result
- Result in corrective measures that oppose the initial change
- Bring the body back to its set point
- Maintain homeostasis
