LOI 2 Quiz: Body Systems Part 1

Some of the protists had flagella or tails. Which statement below accurately describes how the function of the flagella affects another life function?

• The flagella is used to capture smaller prey for energy

• When the flagella moves quickly, the protist heart rate increases

• The flagella allows for movement away from excess light or heat and toward materials the protist need for life processes

• When the flagella is moving, the protist cell is able to take in oxygen and excrete carbon dioxide

What is the function of the muscular system?

• Movement and stability

• Communication

• Transport of oxygen and nutrients

• Exchange of gasses

Which of the following statements best describes homeostasis?

• Keeping the body in a fixed and unchanged state.

• The body’s ability to maintain a stable internal environment.

• Removing waste from the body.

• Changing the external environment to accommodate the body's needs.

Which of the following describes the hierarchy of living things?

• Cells are the foundation of the human body, and each cell can carry out all interactions necessary for survival.

• Tissues are the highest level of organization in the human body, and tissues are capable of carrying out specialized tasks necessary for survival.

• Levels of hierarchical organization make it possible for cells, tissues, organs, and organ systems to specialize and take on specific functions.

• There is no overlap in the organization and interaction of organ systems, making it possible for the body to fulfill a wide range of life functions.

Think about the relationship between a neuron and the sending of an electrical signal. Which relationship below shows a similar relationship? Select a relationship that is similar to the following relationship: neuron : send electrical signal

• cardiac cell : muscle cell

• muscle cell : contract to cause movement

• circulatory system : blood cell

• homeostasis : endocrine system

Which of the following sequences shows the correct order of the hierarchical organization of a body system (from smallest to largest)?

• Muscle cell→ Muscle Tissue→ Muscle→ Muscular System

• Bone cell→ Skull→ Bone Tissue→ Skeletal System

• Cardiac Tissue→ Cardiac Cell→ Heart→ Circulatory System

• Brain→ Neuron→ Nervous Tissue→ Nervous System

What is a function of the nervous system?

• Produces movement and stability within the body

• Digestion of food within the body and elimination of waste

• Processes information to send signals to regulate the body

• Circulates blood and moves food through the body
