formen (hole) ovale

- allows blood to enter the left atrium from right atrium closes before birth

ductus arteriosus

- connect pulmonary artery to the aortic arch - allows most blood from the right ventricle to bypass the fluid filled lungs to the fetus fetus can't use lungs to get oxygen

skeletal

- framework of the body consists of bones and other connective tissues - protects and supports body - ribs - cut through sternum

circulatory system differences

- pig heart is slightly different than humans left carotid artery branches from right carotid - fetal adaptations of circulatory system foramen ovale ductus arteriosus umbilical vessels

excretory

- removes liquid waste from the body - kidneys - urinary bladder in between umbilical arteries

respiratory

- responsible for taking in oxygen and expelling carbon dioxide - trachea - lungs - diaphragm

digestive

- series of organs that convert food into energy and nutrients to feed the body - stomach - small intestine - large intestine - pancreas - liver - gallbladder

circulatory

- system that circulates blood and lymph through the body - heart - umbilical vein - umbilical arteries two fetal adaptations - spleen (lymphatic system) - blood enters (deoxygenated) anterior vena cava posterior vena cava right atrium right ventricle - blood returns (oxygenated) left atrium left ventricle

umbilical vessels

- umbilical vein carries oxygenated and nutrient rich blood from the placenta to into the liver - umbilical arteries arise from the iliac arteries in the legs take deoxygenated blood to the placenta

reproductive

- work together for the purpose of sexual reproduction - male testes penis vas deferens epididymis surrounds testes - female uterus ovaries oviducts

Be able to describe the general function of each of the following mammalian systems: circulatory, respiratory, digestive, excretory, skeletal, and reproductive.

left blank intentionally
