FINAL Flashcards
cardiac tissue
forms the contractile tissue of theheart ; striated in appearance; under involuntary contractions
smooth tissue
lack of striations; walls of digestive tract, urinary bladder, & arteries; involuntary control
nervous tissue
forms a communication & coordination within the body; main cell is a neuron
connective tissue
synthesizes the matrix; small amount of cells scattered through the matrix
loose connective tissue
most common; holds organs in place
adipose connective tissue
contains fats which insulates the body & stores energy
blood connective tissue
fluid matrix called plasma; transport substances
integumentary system
skin, hair, nails
skeletal system
supports body structure & protect organs
muscular system
produces body movement & body heat
nervous system
detect changes inside & outside the body
endocrine system
produce hormones which regulate body activity
digestive system
converts food molecules into forms that are absorbed
respiratory system
exchanges gases between air & blood
circulatory system
transports materials to & from cells; help stabilize the internal pH & temp
reproductive system
females: eggs
males: produce sperm
digestive system
convert polymers into monomers to be absorbed by the cell
assimilation
using absorbed food for growth
mechanical digestion
teeth & tongue & churning of stomach
chemical digestion
enzymes break down food into smaller molecules
amylase
enzyme in saliva that breaks the chemical bonds in carbs
zymogen
inactive form of an enzyme
salivary gland
glands of the mouth that produce saliva, a digestive secretion
fundus
upper portion of the stomach
body
central portion of the stomach
pylorus
bottom of stomach
cardiac sphincter
opening from the esophagus to the stomach
pyloric sphincter
opening from pylorus to intestines
function of stomach
temporary storage of food. mixing of food with gastric juices. regulation of a slow, controlled emptying of food into the intestine
parietal cells secrete
hydrochloric acid
chief cells secrete
pepsinogen
duodenum
first part of the small intestine
jejunum
middle portion of the small intestine
ileum
third part of the small intestine
function of the small intestine
digestion & absorption of nutrients
cecum
first part of the large intestine
colon
middle section of the large intestine
rectum
end of large intestine
function of large intestine
water absorption & eliminate fecal matter
systemic circuit
carries blood between the heartt & the rest of the body
liver
site of cholesterol synthesis & detoxify body
pancreas
make insulin which controls blood sugar levels
which side of the heartt handles oxygen-poor blood
right
which side of the heartt handles oxygen rich blood
left
arteries
carry blood away from the ♡
arterioles
vessels that receive blood from the arteries
veins
carry blood to the heartt
venules
small vessels that gather blood from the capillaries into the veins
capillaries
where gas exchange occurs
pulmonary circuit
carries blood to the lungs for gas exchange & returns it to the heartt
diastole
heartt is relaxed
systole
when heartt contacts
