This is the basic unit of the body.

Cell

100

This system brings in oxygen and removes carbon dioxide.

What is the respiratory system?

100

This tissue covers body surfaces.

What is epithelial tissue?

100

This cavity is located in the back of the body.

What is the dorsal cavity?

100

This term means “front of the body.”

What is anterior (ventral)?

100

This region is around the navel.

What is the umbilical region?

100

This is the study of body structure.

What is anatomy?

200

Groups of similar cells working together form this.

What is tissue?

200

This system transports oxygen and nutrients.

What is the circulatory system?

200

This tissue produces movement.

What is muscle tissue?

200

This cavity is located in the front of the body.

What is the ventral cavity?

200

This term means “below another structure.”

What is inferior?

200

This upper middle region is above the umbilical region.

What is the epigastric region?

200

This is the study of how the body works.

What is physiology?

300

Groups of tissues working together form this.

What is an organ?

300

This system produces hormones.

What is the endocrine system?

300

This tissue transmits messages.

What is nerve tissue?

300

This membrane reduces friction between bones in joints.

What is a synovial membrane?

300

This plane divides the body into right and left.

What is the sagittal plane?

300

These regions are located on either side of the epigastric region.

What are the hypochondriac regions?

300

This is the study of how disease occurs and how the body responds.

What is pathophysiology?

400

Groups of organs working together form this.

What is a system?

400

This system manages fluids and electrolytes.

What is the urinary system?

400

This tissue supports and connects body parts.

What is connective tissue?

400

This membrane surrounds the heart.

What is the pericardium?

400

This plane divides the body into front and back.

What is the frontal (coronal) plane?

400

These regions are located in the lower right and left abdomen.

What are the iliac (inguinal) regions?

400

This condition means excess tissue fluid and often causes swelling.

What is edema?

500

ut these in order: organ, system, tissue, cell.

What is cell → tissue → organ → system?

500

This system coordinates body functions.

What is the nervous system?

500

This type of connective tissue stores fat.

What is adipose tissue?

500

This muscle divides the ventral cavity.

What is the diaphragm?

500

This plane divides the body into equal right and left halves.

What is the midsagittal plane?

500

These regions are located on either side of the umbilical region.

What are the lumbar regions?

500

This condition means insufficient tissue fluid in the body.

What is dehydration?
