A&P HW 1

After a hectic football game, your son complained of abdominal pains. You suspect injury to the liver because he was hit in the _______ during the game.

right upper quadrant

The thoracic cavity and abdominopelvic cavity are lined by

serous membrane

The most lateral and superior region of the abdomen is called the hypochondriac region.

True

This system regulates blood volume and pressure, stimulates red blood cell formation, and controls fluid, electrolyte, and acid-base balance.

Urinary system

Three common components of a feedback loop are

a receptor, an integrating (control) center, and an effector.

Your right foot is ______ to your right hand.

ipsilateral

The visceral pleura:

is the outer membrane on the surface of the lungs

lungs are to the respiratory system as the spleen is to the___________system

lymphatic

Blood glucose concentration rises after a meal and stimulates release of the hormone insulin. Insulin travels in the blood and stimulates body cells to uptake glucose from the bloodstream. This reduces blood glucose concentration. This is an example of

negative feedback

When body temperature rises, a center in the brain initiates physiological changes to decrease the body temperature. This is an example of

negative feedback

A structure composed of two or more tissues is termed:

organ

The anatomical position is characterized by all of the following EXCEPT:

palms facing posterior

If a response enhances the original stimulus, the system is classified as a ______ feedback system.

positive

The arm is ________ to the hand.

proximal

Homeostasis is maintained by the nervous and cardiovascular systems.

False

Negative feedback is a self-amplifying chain of events that tend to produce rapid change in the body.

False

T or F In a negative feedback system, the body will respond to an increased blood glucose level by increasing blood glucose to an even higher level

False

The frontal plane passes vertically through the body or an organ and divides it into equal right and left portions

False

The liver is proximal to the diaphragm

False

Homeostatic mechanisms:

help to keep a relatively constant internal environment in the body.

The phalanges are __________ to the metacarpals.

distal

Which region is most proximally located?

femoral

Which of the following does not correctly pair an organ with its organ system?

gall bladder; urinary system

Feeling for swollen lymph nodes is an example of auscultation.

False

Select the statement(s) that accurately describe homeostasis.

The body has the ability to detect change, activate mechanisms that oppose it, and maintain relatively stable internal conditions. The internal state of the body is best described as a dynamic equilibrium in which there is a certain set point and conditions fluctuate slightly around this point.

Metabolism is the sum of

all the chemical reactions in the body anabolism and catabolism.

The trachea is _____ to the esophagus.

anterior

The visceral pericardium is ________ to the parietal pericardium.

deep

The __________ cavity is inferior to the _____________ cavity.

thoracic; cranial

A(n) _____________ is a group of similar cells and their intercellular materials in a discrete region of an organ performing a specific function.
