Homeostasis Test Flashcards
In order for the body to function properly, homeostatic mechanisms must allow the body to:
Regulate wastes, maintain water balance, maintain a constant body temperature
Which part of the feedback cycle monitors internal conditions and detects changes from the set point?
Receptor
Which part of the feedback cycle receives a signal from the control centre and initiates a change?
Effector
We say that the cell model is “Fluid” because:
Proteins can move side to side in between phospholipids
A fluid drop of 1% in the body will result in:
Thirst
We say that the cell model is a “Mosaic” because:
The plasma membrane is made up of several different components
Glucose will move through specific channels in the cell membrane from high to low concentration. This is an example of?
Facilitated diffusion
During Active Transport, materials…
Move against the concentration gradient
What is the receptor for osmoregulation?
Osmoreceptor
What is the effector in hypothermia?
Skeletal muscles
What cellular process uses ATP to move materials against the concentration gradient?
Active transport
A white blood cells ingests a large virus particle. This is called:
Phagocytosis
Waste products are eliminated from the cell in:
Exocytosis
Small vesicles of water are brought into the cell in:
Pinocytosis
Blood pH set point
7.4
