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

Brain

The development of specialized cells from unspecialized stem cells is a description of which of the following basic life processes? Metabolism Movement Growth Differentiation Reproduction

Differentiation

Most of the body's feedback systems, which regulate homeostasis, are positive feedback systems. True False

What plane would you make if you divided a Thanksgiving turkey into equal right and left halves? Parasagittal plane Coronal plane Transverse plane Midsagittal plane Cross-sectional plane

Midsagittal plane

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

Movement

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

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

What is the relationship between the knee and the foot? The knee is distal to the foot. The knee is proximal to the foot. The foot is superior to the knee. The knee is medial to the foot. The foot is lateral to the knee.

The knee is proximal to the foot.

Regulation of blood glucose in the body is an example of homeostasis. True False

True

A positive feedback mechanism is defined as a feedback mechanism that removes the original stimulus a feedback mechanism that reverses a change in a controlled condition a feedback mechanism that reinforces the change in the controlled condition the dominant feedback mechanism of the body

a feedback mechanism that reinforces the change in the controlled condition

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.

a relatively stable internal environment within limits.
