A structure made up of two or more types of tissues that performs a specific set of functions is at what level of organization?

Chemical

Cellular

Tissue

Organ

System

Which system of the body is responsible for elimination of wastes and regulating the volume and composition of the blood, including production of red blood cells?

Urinary

Respiratory

Digestive

Endocrine

Nervous

The development of specialized cells from unspecialized stem cells is a description of which of the following basic life processes?

Movement

Growth

Differentiation

Reproduction

ORDER CUSTOMIZED SOLUTION PAPERS

Cells are able to transport materials from one region of the cell to another just as the body is able to transport substances to different locations, or skeletal muscles (working with your skeleton) can transport you from the sofa to the refrigerator. What basic life process is illustrated by this description?

Metabolism

Growth

Movement

Differentiation

Reproduction

Which of the following situations would represent a serious disruption of the homeostasis of the volume and composition of body fluids?

Eating a normal meal and drinking a glass of water

Normal urination

Sweating on a warm day, but drinking lemonade in the shade afterwards

Drinking a sports drink after playing a game of basketball with friends

Becoming dehydrated as your lifeboat drifts on the empty ocean

The homeostasis of the body is controlled through a series of steps called a feedback system or feedback loop. One component of such systems is a control center. Which of the following organs would frequently serve as the control center for a feedback system (remember, the control center evaluates the disruption to homeostasis, and it also triggers a response)?

Skeletal muscles

Brain

Nerve endings in the skin

Blood and lymphatic fluid

Sweat glands

After working a 12 hour shift at the hospital Louisa comes home and lies down on her bed. She is lying on her back looking up at the ceiling with her head resting on her arms. What is her body position?

Prone

Anatomical position

Supine

Lateral

Medial

Which pair of terms could be used to describe the location of the nose when compared to the location of the eyes?

Medial and superior

Lateral and proximal

Medial and distal

Medial and inferior

Superior and distal

All of the following would be methods of studying anatomy except:

dissection of organs

examination of tissues with a microscope

investigating the chambers of the heart

identifying the features of the bones of the arm

using devices that measure heart rate and respiration

Which of the following is found within cells?

plasma

cerebrospinal fluid

interstitial fluid

aqueous fluid

cytosol

Which of the following techniques would best reveal the physiology of a structure?

Endoscopy

Magnetic Resonance Imaging

Ultrasound

Positron emission tomography

Homeostasis is the condition in which the body maintains:

the lowest possible energy usage.

a relatively stable internal environment within limits.

a static state with no deviation from preset points.

a changing state within an unlimited range.
