red blood cell
carries oxygen; are red because they contain the pigment hemoglobin; do not have a nucleus
pigment in red blood cells that binds to oxygen increasing the surface area of blood by nearly 60 times
has sudden appearance of purple marks under skin, bruises easily, does not clot after being cut
when your heart stops working and blood is not pumped. you can die shortly because you can not survive without the substances (oxygen mostly) that your blood carries.
before blood is pumped back to the body cells of the fish it first goes through the heart and then to the...
when blood returns to the heart from the body, which does it pass through first, a ventricle or an atrium?
what structure partially separates the left and right ventricles in reptiles and makes it so that the heart can correctly be called an incomplete four chambered heart?
what structure is found between atriums and ventricles that makes sure blood flows in one direction?
the body's ______ line of defense is to keep pathogens away from the body by using the skin, mucus, tears, sweat...
the body's reaction when a pathogen enters the body, millions of white blood cells are produced to fight the infection. The white blood cells get rid of the bacteria, and the tissue that is infected may become swollen and painful

once oxygen is in your lungs, it moves from the air spaces in your lungs into the blood stream by this process. (high to low concentration)
oxygen moves from the red blood cells to the body cells by this process. (high to low concentration)
once oxygen enters the body cells, it combines with glucose (in the process of aerobic respiration) to form ATP. within which organelle does this chemical reaction known as aerobic respiration take place?
carbon dioxide is made in body cells and then enters the blood by this process. (high to low concentration)
Once at the lungs, the carbon dioxide in the blood leaves the blood and enters the air spaces in the lungs by this process. (high to low concentrations)
passageway for air and food. space at the back of the throat where cilia hairs push mucas that has caught dust and other particles that are not wanted in the lungs and clump it all together to be spit/ caughed out or swollowed.
flap that covers the trachea when you swollow to prevent food from going down "the wrong pipe"
