Why do cells require a good supply of oxygen?
Cells require oxygen for cellular respiration, which is the process that generates energy in the form of ATP. Without oxygen, cells would not be able to efficiently convert nutrients into energy. This energy is needed for essential cellular functions and survival.
What is the blood supply of arachnoid mater?
The middle meningeal artery supplies most of the blood for the dura mater, though the meningeal branches of the posterior and anterior ethmoidal artery also contribute.
Why do bone injuries heal much more rapidly than injuries to cartilage?
Because of the lack of blood supply to cartilage, (a new technique to hasten healing of injuries is to introduce fresh blood flow into the area) whereas the marrow in bones actually produce red blood cells, and bones are actually a honeycomb like structure, and they are constantly being taken apart, and rebuilt, microscopic bit by bit.
Is the bronchiole surrounded by blood capillaries?
No, bronchioles are part of the respiratory system and are not surrounded by blood capillaries. Bronchioles are airways within the lungs that help transport air to the alveoli for gas exchange. Blood capillaries are located near the alveoli for the exchange of oxygen and carbon dioxide.
Is there a cell in humans that don't have DNA?
No. Not all cells have a nucleus, which contains nuclear DNA; but all cells have mitochondria, which have their own DNA, called mitochondrial DNA, or mDNA. In humans, the cells that lack a nucleus and therefore nuclear DNA, are mature red blood cells, but they do have mitochondria and mitochondrial DNA.
Where do red blood cells get oxygen?
If by that you mean where they get their own oxygen, then from nowhere because red blood cells do not need oxygen, they perform all reactions anaerobically.If you mean where they get it to give off for the rest of your body, then its from the lungs.
How does heart attack affect tissues?
A heart attack is an obstruction to the blood supply to the heart's own tissues. In the brain this is a stroke and in the lungs it is a pulmonary embolism. Depending on the severity of the blockage, and how long before treated, the tissues without blood supply will die.
All living cells of the epidermis receive their nourishment from blood vessels located in the?
dermis. The dermis contains a network of blood vessels that supply oxygen and nutrients to the epidermis, which lacks its own blood supply. This nourishment is essential for the growth, repair, and maintenance of the skin cells in the epidermis. Additionally, the dermal blood vessels help regulate temperature and support the overall health of the skin.
How do blood vessels help cancer cells to multiply?
Without oxygen and nutrients, the cell will die. So it needs to grow it's own blood supply to survive. This is called angiogenesis. The cancer cells may be able to stimulate normal cells to produce angiogenic factors to help produce new blood vessels. Scientists researching how tumours grow think that a cancer can't grow much bigger than a pin head before it needs to develop its own blood supply.
What is the name of the heart muscle that has its own supply of blood from vessels?
The heart muscle that has its own supply of blood from vessels is called the myocardium. It receives its blood supply primarily through the coronary arteries, which branch off from the aorta. This blood supply is crucial for delivering oxygen and nutrients to the heart muscle, enabling it to function effectively.
Which type of engines carries its own supply of oxygen?
A rocket has it's own supply of oxygen.
What is the medical term meaning tissues without their own blood supply?
The medical term for tissues without their own blood supply is avascular tissue. These tissues rely on diffusion to obtain nutrients and oxygen from nearby blood vessels. Examples include cartilage and cornea.
How is oxygen transpoted by blood?
Hemoglobin is the compound in red blood cells that carries oxygen from the lungs to body cells. The oxygen combines readily with the ion in hemoglobin, and hemoglobin can carry more than twenty times its own volume in oxygen. After releasing oxygen to the cells, hemoglobin collects carbon dioxide and carries it to the lungs where it is exhaled.
How do red blood cells travel?
the heart pumps all of the blood includingplasma (like water)lymph (immune system)white blood cells (fight invading cells)and red blood cells (carry oxygen)the red blood cells travel through theveins (to the heart)arteries (from the heart)capillaries (distribute oxygen to cells)
Why does the heart muscle need oxygenated blood?
the heart is a muscle, and every muscle needs blood because the blood caries oxygen to the cells of that muscle which is then converted into energy and this is what makes our bodies work. your heart however is a special muscle that pumps your blood to all of the muscles in your body.
Which circulatory system of vessels provides the heart with its own blood supply for nutrients and oxygen?
coronarymy testiclescoronary this is the correct answer
Which type of engine carries its own supply of oxygen?
A rocket has it's own supply of oxygen.
