mesentery

Back 24

he mesentary is a double thick layer of peritoneum that is at the back, and attaches to the stomach to help to support and hold the intestines in place.

Front 25

lymph nodes

Back 25

circulates the interstitial fluid called lymph to the body cells and tissues. It also collects waste substances from the bloodstream. Lymph contains white blood cells (WBCs) as its major component

Front 26

denitition

Back 26

development of teeth and their arrangement in the mouth.

Front 27

peristalsis

Back 27

contraction of smooth muscles

Front 28

interventricular septum

Back 28

e stout wall separating the lower chambers (the ventricles) of the heart from one another.If it was not present (as is the case in some animals like alligators) then the oxygenated blood that has been to the lungs would mix with the blood that has not yet been oxygenated. This means that the blood going round the body would be poorly oxygenated. With the use of the septum all the blood going round the body has been freshly oxygenated and this creates a much more efficient system.

Front 29

pericardium

Back 29

Keeps the heart contained in the chest cavity.

Prevents the heart from overexpanding when blood volume increases.
The pericardium is the fluid filled sac that surrounds the heart

Limits heart motion.

Front 30

larynx

Back 30

is an organ in the neck of mammals (including humans) and many other vertebrates involved in breathing, sound production, and protecting the trachea against food aspiration.

Front 31

coronary arteries and veins

Back 31

the coronary arteries feed oxygenated blood to the blood muclse where as the coronary veins take the deoxygenated blood back the heart.

Front 32

epiglottis

Back 32

flap that is between pharynx and trachea. prevents from chokeing

Front 33

right and left cartid arties

Back 33

The carotid arteries supply oxygenated and nutrient filled blood to the head and neck regions of the body.

Front 34

thymus

Back 34

Front 35

masseter muscle

Back 35

function:chewing
location: face

Front 36

aortic arch

Back 36

lows the Aortic arch to stretch during systole, and the elastic recoil allows it to propel blood during diastole, thus a continual supply of blood is given to the tissue, i.e. acts as a pressure resevoire.

Front 37
