Q1- Test #2 Human Body Structural Levels/Supporting Cells Test

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

• The respiratory and circulatory systems work together to deliver oxygen to the cells.

• The endocrine system regulates oxygen levels in the bloodstream.
• The nervous and muscular systems transport oxygen directly to the cells.
• The digestive and excretory systems are responsible for oxygen delivery.

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

• The nervous system controls digestion and nutrient absorption.
• The endocrine system regulates blood pressure and heart rate.
• The integumentary system protects the body from foodborne pathogens.
• The digestive system breaks down food, the circulatory system transports nutrients to cells, and the respiratory system supplies oxygen for energy production.

Explain how the circulatory system supports aerobic cellular respiration.

• The circulatory system only transports hormones to cells.
• The circulatory system delivers oxygen and nutrients to cells and removes carbon dioxide, facilitating aerobic cellular respiration.
• The circulatory system primarily removes waste products without aiding in oxygen transport.
• The circulatory system is responsible for digestion and absorption of nutrients.

The one thing that supplies energy to cells is

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

• ❍ A Nervous system only
• ❍ B Respiratory system only
• ❍ C Nervous and respiratory systems
• ❍ D All systems might be affected.

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

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

Aplastic anemia is a disease that decreases the production of red blood cells in the bone marrow of leg and arm bones. One of the symptoms of aplastic anemia is severe headaches. Explain why that might be so

• Severe headaches in aplastic anemia may occur due to insufficient oxygen delivery to the brain caused by decreased red blood cell production.
• Headaches result from high blood pressure due to excess red blood cells.
• Severe headaches are caused by an increase in red blood cell production.
• Severe headaches are unrelated to red blood cell levels and are caused by dehydration.

General functions of epithelial tissue include ______,________, and __________.

• protection, response, and maintenance.

• protection, structure, and maintenance.

• protection, response, and motion.

• None of the above

________ are specialized cells of one type that are similar in structure and perform a common function.

White blood cells are called ________.

• Erythrocytes
• Goblet cells
• Leukocytes
• None of the above
