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.
