whole blood

red blood cells, white blood cells, and platelets

plasma

\
liquid portion of blood

formed elements

cells and cell fragments: erythrocytes (RBC), leukocytes (WBC), thrombocytes(P)

leukocytes W

fight infection

Erythrocytes R

carry oxygen from the lungs to the rest of the body

Thrombocytes

help prevent bleeding and cause clumping

majority of formed elements

rbc

blood cells are made

bone marrow

function of hemoglobin

Protein contained in red blood cells that is responsible for delivery of oxygen to tissues 

anemia & causes

Body does not have enough red blood cells, iron deficiency, vitamin b12 deficiency, folate deficiency.

Erythropoietin

A hormone that is made by your kidney to stimulate the production of red blood cells. Released by a response to low blood oxygen levels

Blood Group A

A antigens Anti-B antibodies

Blood Group B

B antigens Anti-A antibodies

Blood Group AB

both A and B antigens, no antibodies

Blood Group O

no antigens both Anti-A and Anti-B antibodies

Thrombocytopenia

not enough platelets, You may have trouble stopping bleeding

platelets made of

very large cells in the bone marrow called megakaryocytes

pulmonary circuit

\
blood between heart and lungs

systemic circuit

heart and rest of the body

Arteries

thicker walls, closer to heart, receive more pressure

veins

thinner walls, farther from heart, less pressure

sphygmomanometer

instrument used to measure blood pressure

reason for measuring in arteries

Because every time your heart beats it pumps into the arteries

systolic pressure

top number, max pressure heart exerts while beating

diastolic pressure

bottom number: amount of pressure in arteries between beats

capillaries in systemic circuit

allow the transfer of nutrients and oxygen to organ and muscle cells, and the removal of waste and carbon dioxide

capillaries in pulmonary circuit

collect and form the pulmonary veins that bring oxygenated blood back to the left atrium

Tubular reabsorption

water and solutes not reabsorbed by capillaries are able to return to the bloodstream

Lymphatic vessels

what do water and solutes go through
