3) Barry, a 62 year old man, suddenly fainted while walking inside Wal-Mart. He was transported to the hospital. After several tests, they found that he broke his hip and needed

surgery. They also found that the oxygen level in his blood was very low and were concerned

that he was not getting enough oxygen to his brain, which must have triggered his fainting spell.

What systems are affected?

Why?

three systems affected are:

1. respiratory system

2. skeletal system

3. nervous system

Explanation:

From the text, three systems are affected, and they are:

1. respiratory system

2. skeletal system

3. nervous system

1. Respiratory system. The statement "the oxygen level in his blood was very low" highlights that the body cells were not getting enough oxygen during respiration. This could either be during the gaseous exchange in the lungs or during cellular respiration.

2. Skeletal system: When Barry fell, he broke his hip. The hip bone is the bone that forms part of the pelvic girdle in the skeletal system.

3. Nervous system: It was also suggested that the fainting episode was because the brain was not getting enough oxygen for respiration and metabolism, hence the brain (central nervous system) was affected
