Oxygen diffuses directly across the cell membrane and requires nothing to carry it.
The trachea carries air from the larynx to the lungs. The trachea is a tube that leads to two smaller tubes called bronchi See http://en.wikipedia.org/wiki/Hemoglobin
Oxygen is transported to all body cells by red blood cells in the bloodstream. As blood flows through the lungs, oxygen diffuses into the blood and binds to hemoglobin in red blood cells. The red blood cells then transport the oxygen to tissues and organs throughout the body where it is released and taken up by cells for energy production.
The cells in the nose and throat that trap dust particles are called cilia. Cilia are hair-like structures that line the respiratory tract and help to sweep foreign particles, such as dust, towards the throat to be expelled from the body.
When carbon monoxide is present in the blood, it binds to hemoglobin more effectively than oxygen, reducing the amount of oxygen carried by red blood cells to tissues and cells. This can result in oxygen deprivation, leading to symptoms like dizziness, headaches, and potentially life-threatening conditions.
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
The oxygen molecules enter the bloodstream by diffusing through the thin walls of the capillaries that surround the air sacs in the lungs. These capillaries are where the exchange of gases like oxygen and carbon dioxide occurs. The oxygen molecules bind to hemoglobin in red blood cells, and are then transported throughout the body to cells and tissues that need oxygen for energy production.
Viruses do not have complex membranes like eukaryotic organisms have. Viruses also do not have cells, nor are they technically living organisms. There is no need for viruses to control the movement of material in and out of the viral particles.
Cilia acts like a filter. It traps dirt particles that we inhale and moves these particles out of the body.
Yes they love the taste. It is quite different to normal particles but they taste like chicken.
The heart is responsible for pumping blood throughout the body, which carries oxygen and nutrients to cells. The digestive system, which includes organs like the stomach and intestines, moves food through the body via a series of muscular contractions.
The heart pumps oxygen-rich blood to the body through arteries. Blood delivers oxygen and nutrients to cells, and picks up waste products like carbon dioxide. Veins then carry oxygen-poor blood back to the heart to be pumped to the lungs for oxygenation.

That would be the Respiratory System. The respiratory system is responsible for the gas exchange in the cells of your body. When you inhale (or breathe in), air passes through your nose, down your windpipe, and into two tubes called the bronchial tubes. These tubes lead into your lungs. The tubes branch many times, like a tree, so that your lungs are filled with tiny tubes. The smallest tubes can only be seen with a very strong microscope. At the ends of these tubes are air sacs. Air is moved from the air sacs into the cells of the body by diffusion. This is the movement of a substance from an area with a lot of that substance to an area with less of the substance. When the oxygen-poor cells arrive in the lungs from the heart, the oxygen moves into the cells. The CO2 (carbon dioxide), on the other hand, is more concentrated in the cells, so it moves out of the cells, and into the air sacs. When you exhale (or breathe out), the CO2 leaves your body by the same path by which the oxygen entered. Breathing is only a part of voluntary movement. Part of the reason that you breathe is involuntary. It is caused by the movement of muscles called the diaphragm. This is a sheet of muscles beneath your lungs. When the diaphragm moves downward, it increases the space around the lungs. When the diaphragm moves up, it decreases the space around your lungs, and the air rushes out.
Red blood cells, also called erythrocytes, carry oxygen from the lungs to the rest of the body tissues. These cells contain hemoglobin, a protein that binds to oxygen and facilitates its transport throughout the body.
It moves vesicles, granules, organelles like mitochondria. They are like conveyer belts inside the cells.
As the energy wave moves through the water, the still water particles start to oscillate or move in a circular motion. The particles transfer energy to neighboring particles causing them to also move in a wave-like pattern. This movement is what we perceive as the wave passing through the water.
