Exam 1: Introduction to Physiology and Homeostasis

A ____________________ is a collection of organs that perform related functions and interact to accomplish a common activity that is essential for survival of the whole body.

Organs are composed of two or more kinds of primary tissues.

Match the components labelled a. through d. with their correct role.Temperature-sensitive nerve cells monitor the body temperature and provide information about its status to a temperature-control centre in the hypothalamus, a part of the brain. The hypothalamus can bring about adjustments in body temperature by inducing shivering or sweating, among other things. a.controlled variable b.integrator c.sensor d.effector -skeletal muscles and sweat glands

With positive feedback, a control system's input and output continue to enhance each other.

Glands are formed during embryonic development by pockets of epithelial tissue that dip inward from the surface.

Blood is a type of connective tissue.

Match the terms labelled a. through d. with their correct descriptions. (Options may be used more than once or not at all.) a.nervous tissue b.epithelial tissue c.muscle tissue d.connective tissue -Glands are a derivative of this tissue type.

The plasma surrounds and bathes all the body's cells.

In a negative-feedback loop, which component produces a response that changes a controlled condition?

Feedforward mechanisms bring about a response in reaction to a change in a regulated variable.

Match the terms labelled a. through d. with their correct physiological events. (Options may be used more than once or not at all.) a.intrinsic control b.negative-feedback control c.positive-feedback control d.feedforward control -rapid clotting of blood due to increasing levels of platelet activity at a site of vessel damage

Exocrine glands are the only structures in the body capable of secretion.

The skin is part of the integumentary system.

Match the components labelled a. through d. with their correct role.Temperature-sensitive nerve cells monitor the body temperature and provide information about its status to a temperature-control centre in the hypothalamus, a part of the brain. The hypothalamus can bring about adjustments in body temperature by inducing shivering or sweating, among other things. a.controlled variable b.integrator c.sensor d.effector -body temperature

Which of the following statements is NOT correct for connective tissue?

Intestine, heart, and skin do not consist of hormone-secreting cells.

Which of the following is a type of connective tissue?

When a blood capillary is cut, a clot forms under which feedback control system?

Secretion refers to the release from a cell, in response to appropriate stimulation, of specific products that have, in large part, been synthesized by the cell.

Match the terms labelled a. through d. with their correct descriptions. (Options may be used more than once or not at all.) a.nervous tissue b.epithelial tissue c.muscle tissue d.connective tissue -The blood is this tissue type.
