In vertebrates, the various cells of blood are made in the bone marrow in a process called hematopoiesis, which includes erythropoiesis, the production of red blood cells; and myelopoiesis, the production of white blood cells and platelets. During childhood, almost every human bone produces red blood cells; as adults, red blood cell production is limited to the larger bones: the bodies of the vertebrae, the breastbone (sternum), the ribcage, the pelvic bones, and the bones of the upper arms and legs. In addition, during childhood, the thymus gland, found in the mediastinum, is an important source of lymphocytes.[8] The proteinaceous component of blood (including clotting proteins) is produced predominantly by the liver, while hormones are produced by the endocrine glands and the watery fraction is regulated by the hypothalamus and maintained by the kidney. Healthy erythrocytes have a plasma life of about 120 days before they are degraded by the spleen, and the Kupffer cells in the liver. The liver also clears some proteins, lipids and amino acids. The kidney actively secretes waste products into the urine.
The systemic circualtion enters the heart at the right atrium. This blood is carried here by the superior and inferior vena cava and the coronary sinus. The pulmonary circulaiton is carried tothe heart by the pulmonary veins and is deposited in the left atrium.
blood doesn't come from the heart. Blood cells are produced in the marrow of bones.
It goes to the parts of the body that need blood. So which is practically your whole body.
The blood in your heart travels all throughout your body. The blue, deoxygenated blood, however, goes to your lungs in order to become oxygenated first, before traveling through your body.

What does blood deliver to the heart?
The heart delivers blood to itself, one half gets "fresh" blood, while the other half gets the blood that comes back after being circulated through the entire body.
When does the muscle of the heart gets is blood supply?
Of course heart muscles need a blood supply for the cellular respiratory process as the blood carries the final electron acceptor oxygen which is key to oxidative phosphorylation in humans.
What will happen to your resting heart rate as your heart gets stronger?
With exercise your resting heart rate should be reduced as your heart is more effecient at pumping blood and does not need to work as hard.
Which parts of the heart that sends blood to the brain?
left part of heart
Why is the aorta at the top of the heart?
to be closer to the brain which gets 1st dibs at oxygenated blood after the heart itself
What blood gets from the heart?
The heart is a pump that circulates the blood around the body
What would happen if the blood entering the heart mix with blood leaving the heart?
if blood entering the heart gets mixed with blood leaving the heart the the blood leaving the heart will get poluted. the blood entering the heart is poluted when it enters the heart, the heart cleans it up; so when the blood leaves the heart it is clean so if it gets polluted the person may get sick and this leads to his/her death.
What are the 2 blood circuits of the body?
The two blood circuits of the body are the systemic circulation, which carries oxygen-rich blood from the heart to the body tissues and back to the heart, and the pulmonary circulation, which carries oxygen-poor blood from the heart to the lungs for oxygenation and back to the heart.
How is blood helpful to your heart?
It gets oxygen to it.
What body part send blood up to your heart?
every body part you have sends blood to your heart
Which part of the heart that send blood to the brain?
left part of heart
What are the difference between heart attack and a stroke?
Heart attack occurs when blood flow to a part of the heart is blocked by a blood clot. Without oxygenated blood, the heart muscle begins to die.Stroke is a brain attack, cutting off vital blood flow and oxygen to the brain. Stroke happens when a blood vessel feeding the brain gets clogged or bursts.
Where does the left side of the heart get its blood from?
It gets the blood from the rest of your body blood that is pumping
What part of the blood vessel carry blood away from the heart?
The ARTERIES carries the blood away from the heart.
What does the septum do in the circulatory system?
The septum is a partition which divides the heart into left and right. The right side gets all the impure blood from the body and this is pumped out to the lungs where it gets oxygenated or purified. This blood then returns to the left side of the heart and is then pumped out to supply the tissues. The septum therefore separates the deoxygenated blood from the oxygenated blood
What is the name of the part of the heart that brings the unoxygenated blood back to the heart?
veins, but technically, they are not part of the heart.
What part of pulmonary circulation is systemic part of the path of blood through the heart is pulmonary?
The systemic circulation is the part of the circulatory system that carries oxygenated blood away from the heart to the body and returns deoxygenated blood back to the heart. In contrast, the pulmonary circulation is the part of the circulatory system that carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart.
