Body Cavities Practice Worksheet Answers

Are you looking for answers to your body cavities practice worksheet? Look no further! In this post, we’ll go through the answers to help you understand and reinforce your knowledge of the different body cavities.

What are Body Cavities?

Before we dive into the answers, let’s quickly review what body cavities are. Body cavities are hollow spaces within the body that contain and protect internal organs. There are two main types of body cavities: the dorsal cavity and the ventral cavity.

Dorsal Cavity

The dorsal cavity is located in the back of the body and contains the brain and spinal cord. It is further divided into two sub-cavities: the cranial cavity and the spinal cavity.

Cranial Cavity

The cranial cavity is the space within the skull that contains the brain. It is protected by the cranium, which is made up of eight bones fused together.

Spinal Cavity

The spinal cavity is the space within the vertebral column that contains the spinal cord. It is protected by the vertebrae, which are stacked on top of each other to form the spine.

Ventral Cavity

The ventral cavity is located in the front of the body and contains the thoracic and abdominal cavities.

Thoracic Cavity

The thoracic cavity is the space within the chest that contains the heart, lungs, and other organs. It is protected by the ribcage and the sternum.

Abdominal Cavity

The abdominal cavity is the space within the abdomen that contains the digestive organs, such as the stomach, small intestine, and liver.
