Flashcards in Unit 1 - Cells, Tissues, And Organ Systems Deck (32)
Basic unit of a living organism that can perform all the processes associated with life (Pg. 1)
Movement of particles from an area of high concentration to areas of lower concentration (Pg. 33)
Having or being made up of two or more cells; most plants and animals are examples (Pg. 13)
Group of different types of tissues that work together to form a function (Pg. 3)
In cells that have a nucleus, small structures that work within a cell preforming specific functions for the cell (Pg. 13)
Movement of water particles through a selectively permeable membrane from a area of higher concentration to an area of lower concentration (Pg. 34)
Allowing certain substances, but not others, to pass through; cell membranes are an example (Pg. 33)
Group of organs that work together to perform a function (Pg. 45)
Group of the same type of cells that work together to perform a specific function (Pg. 3)
Having or being made up of only one single cell; most microscopic organisms are examples (Pg. 13)
The liquid-like substance contained in the cell (Pg. 13)
Cells in different parts of the body having special features that enable them to perform specific functions (Pg. 39)
Red Blood Cells
Cells that can carry oxygen to all the cells of the body (Pg. 39)
Tissue which supports other tissues and connects different parts of the body; includes blood, fat, bones, cartilage, and tendons (Pg. 39)
Tissue that covers the surface of the body and the outside of organs; includes skin and the linings of passages inside the body (Pg. 39)
Tissue that carries messages to and from the brain and other parts of the body; includes brain, spinal cord, and nerves (Pg. 40)
Tissue that allows the body to move; specialized for contraction (Pg. 40)
Depending on one another - here this refers to the concept that the body’s organ systems depend on one another to function (Pg. 43)
A series of organs responsible for taking in oxygen and expelling carbon dioxide.
A group of organs working together to convert food into energy and basic nutrients to feed the entire body.
A complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.
The system of an organism's body that performs the function of excretion, the bodily process of discharging wastes.
Is an organ system that permits blood to circulate and transport nutrients oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body.
Fist-sized organ that acts as a hydraulic pump for the circulatory system; pumps blood throughout the body; has a squeezing (contracting) action followed by a relaxing action (Pg. 50)
Tube-like blood vessels that take blood away from the heart, transporting it to to other parts of the body (Pg. 50)
In animals: tube-like vessels that transport blood from the organs back to the heart (Pg. 50)
Bulge in an artery caused by the entry of new blood (Pg. 50)
Tiny air-filled sacs in the lungs surrounded by blood vessels (Pg. 61)
Thin, hair-like vessels connecting arteries and veins; capillary tissue is only one cell thick (Pg. 62)
A change in the environment that triggers a reaction or response (Pg. 66)
Worldview suggesting that everything is interconnected (Pg. 7)
