The two systems most responsible for maintaining homeostasis are the

Endocrine and nervous systems

Homeostasis is the condition in which the body maintains:

a relatively stable internal environment within limits.

Baroreceptors are typically found in the

blood vessels

Atoms and molecules are part of which level of organization in the human body?

chemical

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

differentiation

Which feedback system structure receives output from the control center?

effector

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

false

This system protects the body, helps regulate body temperature, and makes vitamin D.

integumentary system

Which term refers to the sum of all chemical processes that occur in the body?

metabolism

This system produces body movements, stabilizes body positions and generates heat.

muscular system

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

organ

Which subspecialty of physiology deals with the study of functional changes associated with disease and aging?

pathophysiology

Which feedback system structure provides input to the control center?

receptor

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)?

the brain

What controls blood pressure in the body?

the medulla oblongata

Baroreceptors detect increases in blood pressure. true or false

true

High blood pressure may lead to internal bleeding and possibly stroke. true or false

true

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

true

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
