Because your cells need oxygen. Blood has Hemoglobins inside it, which carry oxygen.

What is the mineral needed for the transport of oxygen in the blood is?

Iron is the mineral needed for the transport of oxygen in the blood. It is a crucial component of hemoglobin, the protein in red blood cells that binds to oxygen and carries it from the lungs to the rest of the body.


Why is hemoglobin present in red blood cells?

It makes the red blood cell much better at carrying oxygen!! It can absob oxygen easily and doesn't "leak" oxygen as the blood travels to the body tissues where the oxygen is needed!


List the mechanisms for transporting oxygen and carbon dioxide in the blood?

The mechanisms for transporting oxygen and carbon dioxide in the blood are the lungs. The blood vessels are also needed for transporting oxygen and dispelling carbon dioxide.


Why is movement of the blood important in terms of oxygen passing into the blood from the lungs?

Oxygen is needed by every cell of the body for respiration to release energy. The blood carries the oxygen from the lungs to all parts of the body.


How can oxygen you bring into the body get into the circulatory system?

The oxygen in each breath is circuited to the lungs where the alveoli absorb the oxygen and passed to the blood cells. The blood cells enter the heart where the oxygenated blood is circulated where needed.

What supplies oxygen to the cells?

Blood delivers oxygen to the cells through the red blood cells. These cells carry oxygen from the lungs to the different tissues in the body where it is needed for cellular respiration.


What gases pass from the blood to the lungs?

blood takes oxygen and gives carbon dioxide to the lungs


Why do people need respiration?

To convert oxygen in the air into a usable form in the blood stream. Without adequate oxygen in the blood your tissues will not get enough oxygen to function properly resulting in tissue ischemia (suffocating) and necrosis (death)


Why does a heart rate change?

HR changes in response to workload, the harder you work the more oxygen is needed. Blood is the transport vessel for that oxygen. Faster HR = more blood and therefore more oxygen.


Where does oxygen rich blood go after leaving the blood?

After the lungs the blood goes to the heart. The heart then pumps the blood around the body via the arteries to where the oxygen is needed. The veins return the blood, with oxtgen removed, to the lungs where it can be oxygenated again.


How is oxygen transferred to the cell?

Oxygen is transferred to the cells by our red blood cells which have a special molecule called hemoglobin inside. The hemoglobin molecule binds to the oxygen molecule and the reb blood cells transports the oxygen to wherever it is needed.
