reabsorption
Facillitated diffusion
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
The movement of blood is called circulation.
Gas movement is greater.
The special molecule in red blood cells is called hemoglobin.
actin myosin and cell movement
Pulmonary circulation is the movement of blood from the heart, to the lungs, and back.
In warmer temperatures, that space can/will expand, molecule movement will increase and collisions will occur. In cooler temperatures, that space can/will decrease & molecule movement will slow down.
Filtration Filtration is accomplished by the movement of fluids from the blood into the bowmans capsule. = Reabsorption = = Reabsorption involves the selective transfer of essential solutes and = water back into the blood.
Heart - arteries - capillaries - veins - heart - lungs - back to the beginning. (All the blood every minute [at rest].) pulmonary circulation
No molecule movement at all.
