process of ingesting and destroying bacterial cells

phagocytosis

not classified as white blood cells

reticulocyte

what gene is inherited as recessive

how many RBC's are in one uL of blood

5 million

agglutinates in anti a typing serum but not in anti b typing serum

blood type - A

agglutinates in anti b typing serum but not in anti a typing serum

blood type - B

if blood agglutinates in both anti a/anti b

blood type - AB

if blood does not agglutinate in anti a/anti b

blood type - O

universal donors

blood type - O

universal recipient

blood type - AB

what determines blood type

antigen protein on surface of red blood cells

supplies heart muscle

coronary circulation

refers to cardiac muscle

myocardium

has thickest wall

left ventricle

regulates and monitors heart rate

medulla

have receptors that detect blood pressure changes

carotid artery

what happens in the cardiac cycle

atria contracts before the ventricles

what causes heart mummers

improperly closing valves

systole

contraction phase of the heart

where worn out and damaged red blood cells are destroyed

spleen

where all lymph in the body is returned to

subclavian vein

what is the importance of lymph nodes

filter lymphs and store lymphocytes

vessels you can see through the skin

veins

carries blood rich in substances absorbed from gastrointestinal tract

hepatic circulation

what prevents back flow of fluid in veins and lymphatics

valves

circulatory system functions

transports materials to and from all cells

what is returned to heart by breathing movements and skeletal muscular contractions

venous blood

force in which blood pushes against arterial walls during ventricular contraction

systolic blood pressure

lymphatic vessels resemble what

veins

carries blood from heart to lungs and back to left atrium

pulmonary circulation

exchange of materials between fetal/maternal circulation occurs in what

placenta

in an overweight person what factor is most responsible for increasing ventricular resistance

vessel length

foreign substance that provokes an immune response in the body

antigen

lymphatic system functions

drains excess fluid from spaces around cells in tissues transports lipids from gastrointestinal tract to blood carry out immune responses

function of large intestine

absorb water

bile and pancreatic fluid act upon foods in

small intestine

greatest digestive activity

small intestine

stores bile for liver

gall bladdar

absorption of digested food occurs in

small intestine

digestion purpose

breakdown food molecules to a size which is easily absorbed

bile is essential in digestion of what

fats

ends products that come from digestion of fats are

fatty acids and monoglyceride

liver functions

maintains blood sugar level detoxifies substances stores vitamins

mechanical digestion involves

mastication of food by teeth churning of food by stomach and small intestine

releases substances into duodenum

stomach gall bladder pancreas

saliva functions

keeps mouth and pharynx moist begins chemical breakdown of food has ducts for transport

digestion of proteins to peptides starts with

mouth

basic building blocks of proteins which are the form needed by body cells

amino acids

absorption of water, glucose and amino acids is done by

villi
