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?

Which is the correct order of the levels of organization from smallest and most simple to largerst and most complex?

• cell, organ, tissue, organ system

• cell, tissue, organ system, organ

• cell, tissue, organ, organ system

• cell, organ system, organ, tissue
