quiz 6 study guide

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

When given an image of a dissected fetal pig, be able to identify the following structures and their functions: thoracic cavity, abdominal cavity, trachea, lungs, diaphragm, heart, umbilical vein, umbilical arteries, spleen, right atrium, left atrium, right ventricle, left ventricle, ductus arteriosus, foramen ovale, stomach, small intestine, large intestine, pancreas, liver, gallbladder, kidneys, urinary bladder, ribs, sternum, testes, epididymis, vas deferens, ovaries, oviducts, and uterus
