Investigation 1-2 Human Systems Interactions

Describe how organ systems interact to get oxygen to the cells.

• Cells get oxygen from the respiratory system. They make their way to the bloodstream through varies parts of the body and the circulatory system carries oxygen to the cells.

• Cells get oxygen from the respiratory system. The oxygen enters the digestive system and helps break down food. The circulatory system then takes over.

• The nervous system allows us to bring in the oxygen and the muscular system give the body the ability to use the oxygen.

• None of these.

Explain how the circulatory system supports aerobic cellular respiration.

• The circulatory system carries oxygen and glucose to the cells.

• The circulatory system is not involved withe ACR it's the respiratory system.

• The circulatory system brings oxygen into the body for ACR.

• The circulatory system helps mix all the nutrients needed in the body.

The one thing that supplies energy to cells is _________.

• sleep

• exercise

• food

• vaccines

A patient goes to the doctor with the following symptoms: trouble breathing, headache, fatigue, hard time thinking clearly. Which organ system or systems are most likely affected by the patient's conditions?

• Nervous
• Respiratory
• Nervous and Respiratory
• All systems might be affected.

Aerobic cellular respiration occurs in cell structures called mitochondria. Cells with diseased mitochondria die. Why do those cells die?

• Aerobic cellular respiration makes food for cells. Without food, the cells die.
• Aerobic cellular respiration makes carbon dioxide and food molecules. The cells become full of the extra molecules and die.
• Aerobic cellular respiration provides usable energy for the cells. Without energy, the cells die.
• Aerobic cellular respiration provides cells with oxygen. Without oxygen, the cells die.

Mark the statements that help describe how the respiratory system and the circulatory system interact in humans. (Hint: some statements are true but don't involve both systems)

• Blood picks up oxygen in the lungs.
• Blood carries carbon dioxide to the lungs.
• Blood carries nutrients to cells in the organs of the respiratory system.
• The two systems don't interact.
• Blood picks up nutrients from the small intestine.

How do symptoms give us clues about different diseases?
