5–6

8%

what are the three functions of blood?

1. Blood transport substances throughout the body through blood vessels

2. Carries nutrients, respiratory gases, and other substances throughout the body

3. Distributes body heat

how many components of blood are there and what are they?

Two components

Solid or formed and liquid

solid component or formed parts of blood are made up of elements that are blank

• Red blood cells

• White blood cells

• Platelets

living

The liquid component of blood is made of of blank elements

• Plasma

Nonliving

?: the ratio of red blood cells to total blood volume

• blood samples are spun in a blank

• Formed or solid elements settle at the bottom and blank rises to the top

hematocrit

• centrifuge

• plasma

?

• liquid portion of blood is made up of blank percent water

• Makes up blank percent of blood volume

• Contains over blank, dissolved substances, including nutrients, salts, or electrolytes, respiratory gases, hormones, plasma, proteins, and various waste

plasma

90%

55%

100

?

• together make up about blank percent of blood

• Red blood cells carry blank

• White blood cells play a role in blank

• Platelets are responsible for blank

formed or solid elements

• 45%

• Oxygen

• Immunity

• Blood clotting

Red blood cells are known as what

Erythrocytes

?

• Blank percent of blood volume

• Function to carry blank

• Shaped like a bio concave disc which blank surface area

• Does not contain this organelle :

• Live for blank – blank days

• Old cells are destroyed in the blank or blank

• Low number or reduced function is blank

Red blood cells/erythrocytes

• 44

• Oxygen

• Increase

• Nucleus

• 100–120

• Liver or spleen

• Anemia

?

• A iron bearing protein that carries blank and gives blood it’s red color

• A single RBC contains about blank million hemoglobin molecules

• Each hemoglobin molecule can carry blank molecules of oxygen

hemoglobin

• Oxygen

• 250

• Four

White blood cell cells are also known as as blank

Leukocytes

?

• defend the body against (bacteria, viruses, parasites, and tumor cells)

• Less than blank percent of total blood volume

• Blank is the increase in white blood cell production to fight infection

White blood cells/leukocytes

• 1%

• Leukocytosis

?

• The process of engulfing and blank, microorganism, cellular debris and other foreign or toxic substances

• Leukocytes can blank the circulatory system and move around inside body tissues to fight in invaders, such as blank

• They respond to certain chemical chemicals released by blank cells

phagocytosis

• destroying

• Leave

• Damaged

?

• Monocytes change into blank when they enter infected tissues

• They recognize in golf and destroy blank cell

macrophage

• macrophages

• Target

A collection of dead leukocytes at the site of an infection

pus

platelets are also known as blank

Thrombocytes

?

• cell blank

• Necessary for blood blank process

• A blood clot on the surface of skin forms a blank

• Blank are caused by bleeding under the skin

platelets/thrombocytes

• Fragments

• Clotting

• Scab

• Bruises
