ScienceGrades 9–12Human Anatomy and Physiology

The Standard

HAP.1: Students will demonstrate an understanding of how anatomical structures and physiological functions are organized and described using anatomical positions.

Locate organs and their applicable body cavities and systems.

2026 Mississippi College- and Career-Readiness Standards for Science · Physiological Functions/Anatomical Structure

Teacher's field guide

What Students Need to Do: Students locate organs in the cranial, vertebral, thoracic, abdominal, and pelvic cavities. They name the body system each organ belongs to.
What Mastery Looks Like: A student places the heart in the thoracic cavity and identifies it as part of the cardiovascular system. They can do the same for the brain, lungs, stomach, and bladder.
Common Misconceptions: Students may put the stomach in the thoracic cavity because it sits near the ribs. They may also assume organs in one system share a cavity, even though the kidneys and bladder do not.
How to Assess It: On an exit ticket, ask students to name the cavity and body system for the heart, brain, stomach, and bladder.

Lesson moves

Give pairs a paper torso and organ cards; have them mark the diaphragm, place each organ, and write its cavity and system.
Ask: Do organs in the same system always share a cavity? Have students use the kidney and bladder to defend their answer.
Play a matching race with organ, cavity, and system cards; pairs check each completed set against a labeled body diagram.
Show a chest X-ray request for lungs and an abdominal ultrasound request for liver; students label each organ's cavity and system.
