The Sac held a council by the river to discuss hunting territories.

The Sac negotiated a treaty with neighboring tribes to secure fishing rights along the river.

During the dissection class, the students carefully examined the lacrimal sacs to understand tear drainage.

During the ultrasound, the doctor noted that the twins each had separate amniotic sacs, reducing the risk of complications.

The surgeon photographed the patient's tear sacs to document the condition before the procedure.

The ultrasound revealed two gestational sacs, indicating a twin pregnancy in its early stages.
