Answer:

2.A.inhalation

3.A.ventricles

4.A.kidneys

5..C.vertebral column

explanation:

2.The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

3.A normal heart has two upper and two lower chambers. The upper chambers — the right and left atria — receive incoming blood. The lower chambers — the more muscular right and left ventricles — pump blood out of your heart.

4.The urinary tract is one of the systems that our bodies use to get rid of waste products. The kidneys are the part of the urinary tract that makes urine (pee). Urine has salts, toxins, and water that need to be filtered out of the blood.

5.The vertebral protect and support the spinal cord. They also bear the majority of the weight put upon your spine. The body of each vertebra is the large, round portion of bone.
