What best describes the blood flowing in an artery?
It is oxygen rich - APEX
What does smokeless tobacco do to the heart?
Smokeless tobacco and cigarettes affects the heart by increasing your chances of getting a heart attack. After constant exposure to the substances in tobacco, the arteries in your body start to shrink. This increases your cholesterol level and white cell count, which in turn causes a blockage in the artery. This restricts the blood and oxygen supply flowing to the heart which triggers the heart attack.
Where does the heart pump to?
Well think of the heart and blood vessles as a race track. It start at the heart goes all they way around then back to the start so the heart pumps blood to the heart, but also ateries have a layer of smooth muscle that automatically contracts to help the movement of blood.
What could cause both feet to swell up while sitting down?
I think they swell up because blood is not flowing well. If you sit for a long time or where you setted is not comfortable for you lower body part, your blood start not flowing well and not reaching the feet you start swelling!
Where does blood travel in your body?
The heart pumps blood through blood vessels. Blood vessels leaving the heart are called arteries, and the blood vessels returning to the heart are called veins. Connecting the arteries and veins are smaller blood vessels called capillaries.It's pumped around through tubes called veins and arteries by the heart.The circulatory system is basically a closed network of tubes. The heart muscles contract, which squeezes blood into the arteries. There are valves in arteries and veins to stop the blood flowing 'backwards' - and so, with each heartbeat, the blood is forced forwards through the circulatory system before returning to the heart to start again.
What is is the function of the mitral valve in humans?
To answer, we must start with the normal blood flow. Blood moves from the Right Ventricle of the Heart to the Lungs, then back to the Left Atrium of the heart and into the Left Ventricle of the heart. The Left Ventricle of the heart pumps the blood to the rest of the body where it will return to the right side of the heart before going into the lungs.The Mitral valve lies between the Left Atrium and Left Ventricle, and keeps blood from flowing backwards from the Left ventricle to to the left Atrium, and backwards into the lungs.A faulty Mitral valve would cause the heart's inability to get good pumping action to supply blood to the rest of the body. It may also allow pressure surges back into the lungs. Or, perhaps cause the right side of the heart which normally just supplies low pressure blood to the lungs to have to work harder and help force the blood through the lungs, and back through the left heart to the body, causing tremendous pressure increases in the lungs.High blood pressure in the lungs can cause a number of problems including secretion of fluids an Congestive Heart Failure.Keep in mind, minor heart murmurs are common, and may not indicate a catastrophic failure.
Where do redblood cells start and end?
Red blood cells are produced in the bone marrow through a process called hematopoiesis and are released into the bloodstream to circulate throughout the body. Their life span is typically around 120 days before they are removed by the spleen and liver.
Why when you exercise you start to pant and your heart heat beat changes?
When you exercise, the muscles cells consume energy. This energy is provided in the form of respiration and digestion, supplied by the blood. When the energy is used, it needs to be replaced quickly, so the heart beats faster. As it moves faster, you need to breathe deeper and faster to supply the fast flowing blood and to cool down the body from the excess heat created by the exercise
What is the general path of blood flow in a fish?
In fish, blood first enters the heart through the sinus venosus, then flows into the atrium, followed by the ventricle where it gets pumped to the gills for oxygenation. The oxygenated blood then travels to the body tissues before returning to the heart to start the cycle again.
What transports blood away from the heart to all body parts?
Arteries are the blood vessels that carry blood away from the heart to all parts of the body. Veins are the blood vessels that carry deoxygenated blood from all body part to the heart and lungs.
How does blood change?
because it does. just face is your blood will change Some changes is start from the heart and blood vessels normally occur with age, but many other changes that are common with aging are due to modifiable factors that, if not treated, can lead to heart disease
Why making rating as the current flowing immediately before the switch is closed must be zero?
Rephrase your question so that it makes sense! <<>> The current through the switch before being closed is zero. The current in the circuit does not start flowing until the circuit's switch is closed.
