Blood is a body fluid that transports nutrients and oxygen to cells and removes waste products.

Blood functions in transport, regulation, fluid restriction, and defense.

Blood transports dissolved substances like nutrients and gases throughout the body.

Blood helps maintain the body's pH balance and ion concentrations.

Blood contains components that defend against toxins and pathogens.

Blood that is bright red due to high oxygen content, usually found in arteries.

Blood that is dull red due to low oxygen content, typically returning from the body.

Blood must maintain a pH level between 7.35 and 7.45, making it slightly alkaline.

An average adult has about 5-6 liters (or 6 quarts) of blood in their body.

Blood consists of plasma (55%), red blood cells (45%), and white blood cells (1%).

Albumin is a plasma protein that helps regulate osmotic pressure in blood.

Another name for red blood cells, which transport oxygen throughout the body.

Blood is viscous (thicker than water), slightly warmer than body temperature, and has a specific color.

Females typically have 4-5 liters, males 5-6 liters of blood.

A mature red blood cell takes about 45 seconds to circulate through the body.

Mature red blood cells last about 4 months in circulation before being replaced.

Blood transports oxygen, nutrients, waste, and hormones throughout the body.

Blood regulates pH, fluid levels, and body temperature.

Blood protects against pathogens and prevents excessive bleeding.

The process of red blood cell formation stimulated by erythropoietin in response to low oxygen levels.

Formed elements in blood are produced by hemocytoblasts in red bone marrow.

A hormone produced by kidneys that stimulates RBC production.

Efficient transport of gases (O2 and CO2) with low energy demands.

A condition where oxygen is insufficient at the tissue level.

Protein in RBCs that binds and transports O2 and CO2; mainly made of alpha and beta chains.

Hemoglobin bound to O2, appears bright red due to oxygen presence.

A protein in red blood cells that carries oxygen.

Hemoglobin not bound to O2, appears dark red; found in low O2 conditions.

Anemia, disease, high altitude, trauma, and blocked vessels cause low oxygen.

Kidneys stimulate RBC production when oxygen levels decrease.

White blood cells that protect the body against infections and produce antibodies; includes 5 types.

Five types include Neutrophils, Eosinophils, Basophils, Lymphocytes, Monocytes.

An essential nutrient required for red blood cell production.

Blood consists of plasma (55%) and formed elements like RBCs and platelets.

Process by which leukocytes engulf and destroy pathogens.

Leukocytes with secretory granules; includes neutrophils, eosinophils, basophils.

Leukocytes without visible granules; includes monocytes and lymphocytes.

Type of granulocyte that makes up 50-70% of white blood cells and is the first responder.
