Unit 5 Test Review: Human Body Systems (NYS Regents Questions)

Although the digestive system is primarily responsible for the breakdown of food, this process can be disrupted if the circulatory system malfunctions. The best explanation for this disruption is that

• human body systems interact with each other to perform life functions

• the circulatory system is the control center of the body

• the digestive system and the circulatory system have many organs in common

• the circulatory system is responsible for the coordination of life functions, including the breakdown of food

The role of antibodies in the human body is to

• stimulate pathogen reproduction to produce additional white blood cells

• increase the production of guard cells to defend against pathogens

• promote the production of antigens to stimulate an immune response

• recognize foreign antigens and mark them for destruction

The human body has many cells that are deep inside the body. For this reason, the human body requires

• a transport system and other organs

• carbon dioxide from the air

• the synthesis of many inorganic compounds

• the breakdown of glucose by the digestive system

The diagrams represent a single-

celled organism and a multicellular organism. Which statement correctly identifies the levels of organization for the structures indicated?

• A and B are tissues; E and G are organs.

• A and B are organs; E and G are systems.

• A and B are tissues; E and G are organelles.

• A and B are organelles; E and G are organs.

The nucleus of a cell coordinates processes and activities that take place in the cell. Which two systems perform a similar function

in the human body?

• nervous and endocrine

• digestive and reproductive

• circulatory and respiratory

• skeletal and muscular

The ability of the human body to keep blood-sugar levels within a fairly narrow range, despite the intake of meals high in

carbohydrates, is an example of

• active transport

• genetic recombination

• homeostasis

• digestion

• trachea and esophagus

• alveoli and liver

• nasal cavity and trachea

• epiglottis and esophagus
