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.
Muscles pump blood throughout the body by contracting and relaxing. When muscles contract, they squeeze the blood vessels, pushing blood forward. This helps to circulate blood to all parts of the body, delivering oxygen and nutrients while removing waste products.
It takes about 1 minute for the heart to pump blood to every cell in the body. This means that all cells receive a fresh supply of oxygen and nutrients within this time frame.
It's true its the muscle that moves your eyes :)
The heart is needed because it pumps oxygen-rich blood to all parts of the body, including the lungs. The lungs only exchange oxygen and carbon dioxide with the air, while the heart circulates the oxygenated blood to nourish the body's cells and remove waste products. Both the heart and lungs work together to ensure the body receives the oxygen it needs to function properly.
No. The heart does not filter blood, it only pumps it around the body. Other organs such as the kidneys and liver have the task of filtering blood.
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.
