Blood doesn’t Float. Water does. But in some cases, it can! When the water is too salty or too cold, blood can’t Float. However, when the water is just right, blood can Float just like other things in the water. This is because when blood tries to Float away from the cell’s surface, it needs oxygen to do so. The water provides that oxygen and blood settle back down to the cell’s surface.
Does blood float in water
It’s a common myth that blood can’t Float in water. In fact, blood can Float just like any other thing that is lighter than water. However, it’s not always easy to see because of the red color of blood. If you have ever seen a bloody nose, you probably know that fresh blood doesn’t look like red in the water. This is because once the cells begin to break down and release their contents, the red blood cells start to sink and the plasma begins to rise up to the top of the water where it looks clear or yellowish-brown.
What Is Blood?
Blood is a fluid that moves through the body. It helps carry oxygen and other nutrients to and from the cells in the body. Blood also helps keep the body working properly.
How Does Blood Float?
Blood can Float because when it tries to escape from the cell’s surface, it needs oxygen to do so. The water provides that oxygen and blood settle back down to the cell’s surface.
- The red blood cells are heavier than the water, so they sink to the bottom.
- The plasma stays on top because it is lighter than water.
- Since the plasma and red blood cells have different densities, they will separate from each other.
- The red blood cells will sink to the bottom and the plasma will float on top of the water.
- The plasma is a liquid so it can move around freely unlike the red blood cells.
Why Can’t Blood Float In Water?
One reason blood can’t Float in water is because it needs oxygen to do so. When the water is too salty or too cold, blood can’t Float. However, when the water is just right, blood can Float just like other things in the water.
- If you have a cut on your finger, the blood will not be able to leave the vein until it is healed.
- If the blood can’t get out of the vein, then it will pool in the capillaries and then will get pumped back into your heart through the veins. This can cause clots to form and cause heart attacks or strokes.
- If you have anemia, then you may have too few red blood cells in your body (low hemoglobin). The red blood cells can’t get out of the veins and they will stay in your blood in the capillaries until they die.
- If you have a fever, then the blood vessels in your body may be too small to allow the red blood cells to pass through them.
- The water’s pressure or temperature may be too cold or hot for the red blood cells to float around in it.
What Else Can Blood Do?
- Your blood is made up of different types of cells. You have red blood cells (RBCs) and white blood cells (WBCs).
- The RBCs carry oxygen through your body’s veins, capillaries, and arteries. They also carry carbon dioxide out of your body through the veins and arteries. If a red blood cell dies, it becomes a platelet. Platelets help the WBCs fight infection!
- White blood cells are like soldiers in your body’s army that fight against bacteria and viruses that cause disease in you or other people!
- When they die they become the body’s waste (called “hemoglobin” since they are part of the hemoglobin molecule in your red blood cells). Hemoglobin is the substance that carries oxygen in your blood to all parts of your body!
- Blood can also transport hormones throughout your body into different parts of it when needed to regulate things like how much salt you need to make your body’s cells work.
How Do You Know if Blood Sinks?
To find out if blood sinks, you can try this experiment:
- Get a tall cup and fill it with water.
- Add food coloring until the water is colored dark pink or red (optional).
- Put your hand in the water and break a small cut on your finger and watch what happens to your blood in the cup of water!
- If the blood sinks to the bottom, it will sink!
How Do Red Blood Cells Work?
- The red blood cells have hemoglobin, which is an iron-containing protein that gives them their bright red color. Hemoglobin is a special protein that allows the red blood cells to take up oxygen from the air and give off carbon dioxide when they use it up.
- The red blood cells also have a protein called myoglobin that helps them store oxygen in the red blood cells so that they can use it when they are floating around in the water.
- The hemoglobin and myoglobin are held together by a special chemical called adenosine diphosphate (ADP) which is released when the red blood cells need oxygen to survive. This is why we call it “hemoglobin’s” job to carry oxygen around in the body!
- When the red blood cells die, they turn into tiny pieces called erythrocytes.
- The hemoglobin and myoglobin are destroyed in the process of turning into erythrocytes.
- Erythrocytes can take up oxygen from the water and give off carbon dioxide during respiration.
- When we breathe in, we take oxygen from the air into our lungs where it is used to make more hemoglobin and myoglobin so that we have more red blood cells to carry around oxygen in our blood!
What Will Happen If Your Blood Has Floated?
- If you have a cut on your finger, the blood will not be able to leave the vein until it is healed.
- If the blood can’t get out of the vein, then it will pool in the capillaries and then will get pumped back into your heart through the veins. This can cause clots to form and cause heart attacks or strokes.
- If you have anemia, then you may have too few red blood cells in your body (low hemoglobin). The red blood cells can’t get out of the veins and they will stay in your blood in the capillaries until they die.
- If you have a fever, then the blood vessels in your body may be too small to allow the red blood cells to pass through them.
- The water’s pressure or temperature may be too cold or hot for the red blood cells to float around in it.
- If there is something that is too heavy for them to float, then they won’t be able to get out of the capillaries.
Conclusion
Blood is a vital liquid that helps carry oxygen and other nutrients through the body. When it floats, it can block some of the oxygen from reaching the blood and cause anemia. In addition, Blood can also cause water to enter through the nose and mouth and form clouds in the air. This can make it difficult for you to breathe and can create a mess if you are trying to drink from a water source that is murky or has blood in it.
