1
New cards
cellular respiration
The conversion of glucose and oxygen into carbon dioxide, water, and ATP.
2
New cards
tissue
A group of similar cells that work together to perform a specific task.
3
New cards
organ
A structure made up of two or more tissues working together to carry out a specific function.
4
New cards
organ system
A group of organs working together to perform a function in the body.
5
New cards
phospholipid
A chemical structure with a hydrophilic head and hydrophobic tails.
6
New cards
solute
A substance dissolved in water or some other solvent.
7
New cards
solvent
The liquid which dissolves a solute.
8
New cards
solution
A mixture of solute dissolved in solvent.
9
New cards
concentration
The amount of solute dissolved in a given amount of solvent.
10
New cards
concentration gradient
When one side of a space has more solute than the other.
11
New cards
semipermeable
A barrier that allows some things to pass through and blocks others.
12
New cards
active transport
The movement of substances across the cell membrane requiring energy.
13
New cards
passive transport

the movement of substances across the cell membrane from a region of high concentration to an area of low concentration

14
New cards
osmosis
The diffusion of water across a membrane.
15
New cards
hydrophobic
Water fearing.
16
New cards
hydrophilic
Water loving.
17
New cards
hypertonic
Concentration of solutes outside the cell are higher than inside the cell.
18
New cards
hypotonic
Concentration of solutes outside the cell are lower than inside the cell.
19
New cards
isotonic
An environment in which the concentration of solutes is equal inside and outside the cell.
20
New cards
diffusion
A type of passive transport where particles move from a region of higher concentration to a region of lower concentration.
21
New cards
facilitated diffusion
The movement of large or charged molecules across a membrane using channel proteins which do not require energy.
22
New cards
endocytosis
An active transport process in which large particles are engulfed into the cell.
23
New cards
exocytosis
An active transport process in which large particles are removed from the cell.
24
New cards
cell receptor
A protein in the cell membrane that receives signals from signal molecules outside the cell.
25
New cards
thermoregulation
The body’s ability to regulate a constant body temperature.
26
New cards
effector
A structure that tries to help the body restore normal homeostasis conditions.
27
New cards
receptor
A sensor that detects change and sends a signal to the control center.
28
New cards
negative feedback
A mechanism by which the body keeps variables close to a specific level.
29
New cards
hormone
Chemical messenger/signals produced by endocrine glands.
30
New cards
vasodilation
Widening of blood vessels to allow heat to leave the body.
31
New cards
vasoconstriction
Narrowing of the blood vessels in the extremities to conserve body heat.
32
New cards
thermogenesis
Shivering to increase body temperature.
33
New cards
dehydration
Having not enough water in the body.
34
New cards
edema
Having too much water in the body.
35
New cards
metabolic waste
A substance left over from processes such as cellular respiration, which must be removed from the body.
