How does oxygen and food get to the cells in your body?
Oxygen is carried to the cells by red blood cells in the bloodstream, where it is picked up by hemoglobin. Food is broken down into nutrients in the digestive system and then absorbed into the bloodstream, where it is carried to the cells for energy and growth.
Why do red blood cells appear red?
RBC's, the blood cells responsible for transferring nutrients, and the blood cells that are highest in volume are actually red. When blood plumps from the lungs, they are plump and happy, so blood is a nice reddish color. When muscles use the oxygen delivered by Red Blood Cells, the cells shrivel a little bit and it causes more of them to fit within the vein. That tight cluster of RBC's actually turns the blood more of a deep red/ purple color.
How much blood loss is considered critical before a transfusion is necessary?
Critical blood loss is typically considered to be around 15-30 of a person's total blood volume, which may require a transfusion to restore adequate blood volume and oxygen delivery to the body.
Why people have more red blood cells in higher altitudes?
Red Blood cells contain haemoglobin which is what the oxygen binds with to form oxyhaemoglobin which is then transported to the different cells around the body. Oxygen bonds with the haemoglobin when it is at high partial pressure and then is released when there is a lower partial pressure of oxygen. At high altitudes there is lower atmospheric pressure of oxygen. This means that the current number of red blood cells in the body cannot meet the cells demands for oxygen. Due to the lower partial pressure of oxygen a process called polycythemia occurs, which is an increase in the bodies red blood cell count. The body increases its red blood cell count because this means there is more haemoglobin available to bond with oxygen molecules meaning more oxygen can be transported to the cells in the body, therefore helping to meet the oxygen demands of the body even with less oxygen in the air.
Why do you breathe slower when you are at rest or sleep?
When you are at rest or asleep, your body's need for oxygen decreases because your metabolic rate and energy expenditure are lower. As a result, your respiratory system slows down to match this reduced demand for oxygen. This helps conserve energy and allows your body to continue functioning efficiently without over-exerting itself.
Why is blood so important why will people die if they lose too much blood?
blood carries a lot of things within your body. Importantly, oxygen. All of your cells need oxygen and cannot live without it. Without blood, they cannot get oxygen.
Why cant you run for as long if you have less oxygen in your blood?
because your blood carries oxygen to you muscles. without much oxygen blood won't be able to take lots to your muscles, and with little oxygen your muscles won't work as well and therefore you won't run as quickly :)
The process where energy is released from glucose without using oxygen is called what?
Without using oxygen the process is called an anaerobic process. The amount of energy is much less (2ATP) compared to aerobic (36 ATP).
What test is used to see how much oxygen is taken in with every heartbeat?
The test used to measure how much oxygen is taken in with every heartbeat is called pulse oximetry. This test estimates the oxygen saturation levels in the blood by measuring the absorption of infrared light in pulsating blood.
How much oxygen goes into the blood?
98% of the oxygen inhaled enters the blood. However, I do not know where the other 2% goes.
How much oxygen is carried in the blood?
1000000000000000 grams
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!
Which substance increases blood level without affecting blood sugar level?
Iron can increase blood levels by promoting red blood cell production, without affecting blood sugar levels. Iron is essential for transporting oxygen in the blood and can help treat conditions like anemia.
What part of the heart carries oxygen without much oxygen?
viens...
Does deoxygenated blood mean no oxygen blood?
Taken literally, deoxygenated means "without oxygen," but physiologically it means blood that has dropped its oxygen load to the tissues. There is still oxygen bound to hemoglobin in deoxygenated blood, just not as much as oxygenated blood.
Does a person who is smoking carry as much oxygen in their blood as a non smoker?
no, the red blood cells carry less oxygen when the person smokes
What if you had too much oxygen?
hyperventilation and your blood becomes to alkaline.
