Here is a draft essay on the endocrine system based on the information provided:
The endocrine system is a network of glands that secrete hormones to regulate bodily functions. This bio lab exercise aimed to familiarize students with the major endocrine structures and their functions. While there were no direct safety concerns, care needed to be taken when handling biological specimens.
