No. Oxygen is held within rebd blood cells which are suspended in the plasma (made up mostly of waer). The heart pumps this suspension, and thus the oxygen, around the body.
Right ventricle. Blood gets pumped from the body to the lungs where it is oxygenated then returns to the heart where it is pumped to the the other organs that need oxygen, e.g. the brain.
When you exercise (especially when you lift wieghts) you break down muscle. Your body needs to repair this muscle which is what makes you get bigger and stronger and in order to do that it needs to pump blood that contains nutrients to those muscles. You heart rate stays elevated for a while because your body is trying to "feed" all of the muscles that you used so it can reppair them.
This would be the cardiovascular system. The heart is the pump and the blood travels through arteries carrying oxygen for the body and the veins return the de-oxygenated blood back to the heart. The blood must pass through the lungs to pick up the oxygen and release carbon dioxide.
Yes your heart is a living thing because it never stops beating until you are dead.
Amoebas have constrictile vacuoles that pump excess water out of their cytoplasm.
muscle that helps to pump oxygen around the body
Because your muscles need oxygen and oxygen is in the blood so the heart pumps bloid around the body
Your lungs are connected to the outside world, to take in oxygen and put out carbon dioxide (water vapor, etc.); lungs use blood vessels to exchange taken in oxygen with the rest of your body.
Oxygen is transported via the Haemoglobin in the red blood cells in your blood. Therefore, the organ that pumps the oxygen around your body is the organ that pumps your blood around your body, which is obviously your heart.
the heart pumps oxygenated blood round the body so that the muscles get oxygen to help them be used in energetic exercises
your heart, when you breath in oxygen is taken in the oxygen gives the heart the ability to send blood around the body
Oxygen, nutrient, waste, etc transportation around the body. Check out the Circulatory system
the heart does not give the body it's oxygen it is the lungs. The heart is used to pump the blood to the lungs to pick up oxygen and then to pump the blood throughout the body and add oxygen to the blood cells.
Your body needs oxygen, which is picked up by the blood from the air in your lungs and then pumped around your body by the heart. If you need more oxygen (by working harder) then your heart has to pump faster.
*does Your body is working harder, so your pulse increases to pump more oxygen around your body through your blood stream.
Because you are making the heart work faster,so it has to pump more blood around it.
Keeps your blood pumping round your body, and never takes a break from it.Blood is good because it carries oxygen and chemicals around your body and delivers it to different parts.Heart is really useful;]The purpose of the heart is to pump blood around the different parts of the body.To pump blood around the body via veins (into the heart) and arteries (out of the heart). The heart oxidises (fills it with oxygen) the blood. The blood's purpose is to deliver oxygen and warmth.
