Formation and development of red and white blood cells from stem cells. Occur in bone marrow.
Stem cell that gives rise to all blood cells, resides in the red bone marrow.
Glycoprotein hormone produced by kidney. Stimulates development/ production of RBCs.
Blood having abnormally low oxygen carrying capacity, due to a reduced number or size of the red blood cells.
A disorder characterized by an abnormal increase in the number of red blood cells in the blood.
A substance produced by the mucosa of the stomach and intestines that is essential for the absorption of vitamin B12.
A group of leukocytes containing granules in their cytoplasm; neutrophils, eosinophils, basophils.
A group of leukocytes without granules in their nuclei; lymphocytes, monocytes.
The most abundant type of white blood cell. They are phagocytic and tend to self-destruct as they destroy foreign invaders, limiting their life span to a few days.
White blood cell that are responsible for combating infection by parasites in vertebrates.
A type of WBC that promotes inflammation and participates in allergic responses.
The two types of white blood cells that are part of the body's immune system.
An agranular leukocyte that is able to migrate into tissues and transform into a macrophage.
Cancer characterized by an increase in abnormal white blood cells.
Stoppage of blood flow.
A blood clot formed within a blood vessel and remaining attached to its place of origin.
A clot that breaks lose and travels through the bloodstream.
Undesirable clot formation.
Antigens formed on the surface of red blood cells, whose presence and structure are genetically determined.
Specific antibodies formed in the blood.
Upper chamber of the heart that receives and holds blood that is about to enter the ventricle.
A chamber of the heart that receives blood from an atrium and pumps it to the arteries.
The largest artery in the body; the large trunk artery that carries blood from the left ventricle of the heart to branch arteries.
Largest vein in the body; either of two large veins that return oxygen-depleted blood to the right atrium of the heart.
One of two arteries (branches of the pulmonary trunk) that carry venous blood from the heart to the lungs.
Any of four veins that carry arterial blood from the lungs to the left atrium of the heart.
Abnormally high blood pressure.
Process of making new red blood cells.
Severe form of anemia that develops as a consquences of loss of functioning red bone marrow.
Progressive anemia that results from a lack of intrinsic factor essential for the absorption of vitamin B12.
Low O2 from irregular shaped RBC , joint pain, thrombosis, anemia fever.
Blood vessels that carry blood away from the heart.
Blood vessels that carry blood back to the heart.
pH between 7.35 to 7.45.
Disorder that results from the incompatibility of a fetus with an Rh-positive blood factor and a mother who is Rh negative, causing red blood cell destruction in the fetus; this condition necessitates a blood transfusion to save the fetus.
The smallest blood vessels which connect the smallest arteries with the smallest veins.
Normal blood pressure for a healthy adult.
A specialized bit of heart tissue that controls the heartbeat.
Picks up electrical impulse from the SA node and causes ventricles to contract, causing blood to move into arteries
Bundle of His
A bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract.
"Heart strings" are tiny white collagenic cords that anchor the cusps to the ventricular walls. They originate from the papillary muscles.
The blood pressure during that part of the heartbeat when the hearts venticles are relaxing.
The blood pressure during that part of the heartbeat when the heart's ventricles are contracted and the blood is being pushed out into the arteries.
