Which of the following statements is TRUE?
The coordinated activity of the organ systems is necessary for normal function.
Because organ systems are so interrelated, dysfunction in one organ system can have profound effects on other systems.
An organism is any living thing considered as a whole whether composed of one cell such as a bacteria or trillions of cells such as a human.
Living things are highly organized and disruption of this organized state can lead to loss of function and death.
All of these statements are true
__________ refers to the specific interrelationships among the parts of an organism and how those parts interact to perform functions.
Organization
Metabolism
Responsiveness
Growth
Development
Growth refers to an increase in size of all or part of an organism. It can result from:
an increase in the number of cells within the organism.
an increase in the size of individual cells within the organism.
an increase in the amount of substances surrounding the cells.
all of these
none of these
__________ includes the changes an organism undergoes through time beginning with fertilization and ending at death.

The scientific discipline that deals with the processes or functions of living organisms is
physiology
anatomic imaging
regional anatomy
surface anatomy
systemic anatomy
The chemical level of organization.
involves the interaction between atoms and the formation of molecules.
is made up of organ systems that are classified as a unit by function.
determines the structural and functional characteristics of all organisms.
Involves the interaction between atoms and the formation of molecules and which determines the structural and functional characteristics of all organisms are correct.
All of these are correct for the chemical level of organization.
Homeostasis is the condition produced by
a resistance to change of any kind.
the tendency for change in a body parameter to be counteracted as soon as the body parameter goes past its normal range of values.
the tendency for continued change in the same direction regardless of current values of any body parameter.
the presence of pathogens.
all of the conditions listed here.
Which of these statements is true of negative feedback?
Negative feedback is important for maintaining homeostasis in the body.
Negative feedback makes any deviation from a normal value larger.
Negative feedback occurs when the uterus contracts during birth.
Negative feedback is a very unusual control mechanism in the human body.
Negative feedback will usually result in illness or other disturbance of normal systems.
Which of these is an example of a positive-feedback mechanism?
An increase in blood pressure activates mechanisms that decrease blood pressure.
Increased amounts of a hormone in the blood cause a decrease in the secretion of that hormone.
Increased carbon dioxide in the blood increases breathing rate, which decreases carbon dioxide in the blood.
Increased amounts of fluid in the blood result in increased quantities of urine, which decreases fluid content of the blood.
Increased stretch of the uterus causes it to contract, which further increases stretch.
Which of the following is NOT the correct name of an organ system?
integumentary
lymphatic
cardiovascular

organelles.
organisms.
organs.
organ systems.
tissues.
Which of these statements about serous membranes is true?
Serous membranes line cavities that open to the outside of the body.
Visceral serous membranes are in contact with internal organs.
Retroperitoneal organs are surrounded by both parietal and visceral serous membranes.
Serous membranes surround the pleural and peritoneal cavities, but not the pericardial cavity.
All of these are true.

A patient arrives at an emergency room with a traumatic pneumothorax after a car accident. In the course of the accident, the patient suffered a penetration wound, which allowed air to fill the space around one of her lungs causing it to collapse. Which serous membranes were likely damaged assuming that the lung itself was not punctured?
visceral pleura
visceral pericardium
parietal pleura
visceral peritoneum
mesenteries
