How does oxygen go round the body?
Oxygen from the air is absorbed through the alveoli of the lungs and attaches itself to Haemoglobin in the bloodstream, becoming "Oxyhaemoglobin" which is bright red in colour and unstable in its nature. Transported by the blood it is then absorbed by the cells to be used by them.
How is oxygen in air replaced?
The Oxygen Cycle. We breath in oxygen We breth out Carbon dioxide. Carbon dioxide is a heavy gas and fall to the ground. Whereupon it is absorbed by plants. Whilst in the plant in the process of photosynthesis carbon dioxide is split. The carbon part is retained in the plant as biomass, and the oxygen part is released back into the atmosphere. for humans, animals etc., to breath/consume. There is also a Carbon Cycle, and a Nitrogen Cycle, where these gases process round through the biosphere of the Earth.
How many grams of oxygen are needed to react with 350g of iron to produce 500g of Fe2O3?
You need 150,41 g oxygen.
How does a mortar fire its ammunition?
Most mortars are muzzleloaders. The mortar tube is a piece of pipe with a firing pin permanently fixed at the base. When the mortar round is dropped into the tube, the primer in the base of the round strikes the firing pin, and the round shoots out the other end. The Russians have fielded breechloading mortars. These are nothing but huge. The LITTLE one fires a 160mm round through a three-meter tube--the tube is in two sections, and the round is placed in the lower, hinged section. (160mm is larger than almost all of their howitzers and guns.) The big one is the 240mm 2S4, which has two exotic rounds available to it. The first is a laser-guided round; this round was used to devastating effect in Afghanistan during the Soviets' war there. The second is a nuclear round.
What will be the mass of oxygen filled in LPG cylinder at normal room temperature?
In India, you have 14.2 Kg of gas filled in domestic cylinder. It contains methane and ethane mixed in "liquid" form. Mass of methane is 16 and that of ethane is 28. Mass of oxygen is 16*2=32. So roughly mass of them you take to be same. Now 1 gram of water turns up into into 1600 ml of vapour or gas. So mass of LPG is 14.2 and you round up it to 14 Kg. So mass of LPG is 14* 1000 =14,000 grams. So LPG would have in "Gas" form, it's mass would have 14,000/1600 = 8.75 grams. You round up it to 10 grams. (This should make up for, you have oxygen molecule heavier than LPG molecule.) So answer would be approximately "only" 10 grams of oxygen can be filled at room temperature, in LPG cylinder. If you store oxygen below minus 183 degree centigrade, you can store it in LPG cylinder and weight will be some where between 14 to 16 Kg.
What is the function for the heart and lungs?
The lungs pull in oxygen which is then taken into the blood stream which is pumped round the body by the heart.
Describe the path of the blood through the body?
You breath in oxygen, oxygen goes to the lungs. The oxygen is carried from the lungs to the heart. The blood cells are filled with oxygen, then pumped through your body. If you feel on your neck below your jaw, you should feel your pulse. This is an artery pumping blood to your brain. Then, the used blood is pumped back to your heart to receive more oxygen and then is pumped back to somewhere in your body.
Why is blood pumped to the lungs before it is pumped round the body?
blood is pumped through lungs
Why is blood pumped to the lungs before its pumped round the body?
To remove CO2 and to replenish the O2 in the blood.
Why do fish only have 2 chambers in the heart?
Unlike mammals, fish absorb oxygen directly into the blood stream at the gills. They don't have lungs so blood doesn't have to be pumped to the lungs to be oxygenated before it can be pumped round the body so they only need 2 chambers in their heart
What transports oxygen within the blood?
The red blood cells carry the oxygen from the lungs round the body. The heart pumps the red blood cells to go around the body. When the oxygen is given to the cells, the red blood cells return to the heart and get pumped back to the lungs while carrying carbon dioxide.
How does plasma flow?
Plasma makes up 60% of blood and is pumped round the body by the heart.
Why does the blood become more darker as it is being pumped round the body?
As blood travels through the body, it delivers oxygen to tissues and organs. Oxygenated blood is bright red, but as oxygen is utilized, the blood becomes deoxygenated and appears darker. This change in color is a result of the oxygen-rich hemoglobin turning into deoxygenated hemoglobin.
Where blood end IN the body?
The blood is pumped by the heart round the body in a circular system, so there is no actual end.
How do oxygen and carbon dioxide move into and out of cells?
Oxygen enters cells through diffusion, where it moves from areas of high concentration in the bloodstream to low concentration in cells. Carbon dioxide exits cells through the same process, diffusing from high concentration in cells to low concentration in the bloodstream for removal by the lungs.
Description of a basketball?
A round sphere that is usually orange coloured and is pumped with air so it can bounce. It is about 10 inches in diameter.
Why do your brakes on your Oldsmobile feel like they are being pumped when you press slowly on the pedal?
Rotors "out of round" and need to be resurfaced or replaced?
