Endocrine System
The endocrine system functions through communication mechanisms that do not involve neurons,
utilizing hormones that are dispatched to various cells possessing specific receptors for these chemical
signals.
Exocrine Glands
Exocrine glands function by secreting substances through ducts to designated locations. Unlike
endocrine glands, the products of exocrine glands are typically released outside the body. Some
prominent examples include:
- Sweat glands
- Digestive glands
- Salivary glands
Hormone Production and Delivery
- Rate of Production: Hormone synthesis and release are primarily controlled by negative feedback
mechanisms, ensuring balance within the body.
- Rate of Delivery: The concentration of hormones reaching target organs can vary based on blood flow;
increased blood flow results in a higher delivery of hormones compared to lower blood flow conditions.
