Melanie Castaneda Name ___________________________ FETAL PIG VOCAB, Week 2 1-ABDOMINAL CAVITY pg. 233-237 umbilical vein part of the umbilical cord umbilical arteries carries deoxygenated blood from fetus to placenta urinary bladder temporary storage for urine peritoneum A smooth membrane that lines the inside of the abdominal cavity liver stores energy reserves, detoxifies poisons, and bile formation gall bladder stores bile produced by the liver bile Aids in fat digestion stomach stores food and releases it to the small intestine spleen functions as part of the immunes system, and removes damaged and worn out blood cells from circulation mesenteries provides support structure for blood vessels and nerve leading to all the abdominal organs pancreas secretes digestive enzymes through a duct into the small intestine. Functions as an endocrine organ. small intestine where enzymes break down, proteins, fats, carbohydrates, and nucleic acids. Where chemical digestion occurs. large intestine the reabsorption of water from wastes that prevents dehydration. kidney they remove nitrogen containing wastes and from urine urinary bladder temporary storage for urine. rectum where the concentrated wastes are stores before being eliminated through the anus 2- URINARY SYSTEM pg. 238-240 urine liquid waste ureter carries the urine to the bladder urogenital opening where urine comes out of homeostasis keeps internal body conditions stable renal artery carries blood to the kidney for filtration renal vein blood returns to the body circulation sphincter muscles urine is held in the bladder by these muscles renal blood vessels carries blood from your heart to your kidneys urinary bladder temporary storage for urine medulla of kidney collects the urine and funnels it to the ureter cortex of kidney where urine formation begins in microscopic structures 3- REPRODUCTIVE SYSTEMS pg. 241-243 Female: uterus birth canal Name ___________________________ uterine tubes (horns) the site of implantation and embryonic development oviduct receives the egg at ovulation, and is also the site of fertilization after copulation vagina receives the penis during copulation and serves as part of the birth canal. genital papilla ventral to anus urogenital opening where urine comes out of rectum where the concentrated wastes are stored before being eliminated through the anus Male: testes site of sperm production epididymis stores, matures, and transports sperm between the testes and vas deferens vas deferens transports sperm to urethra urogenital opening where urine comes out of urethra transports urine from the bladder to the outside of the body rectum where the concentrated wastes are stored before being eliminated through the anus bulbourethral glands gives seminal fluid to urethra 4- INTERNAL STOMACH STRUCTURE pg. 244-246 pyloric sphincter controls the movement of food from the stomach into small intestine cardiac (gastroesophageal) prevents food from moving from the stomach back into the esophagus sphincter 5-SMALL INTESTINE pg. 247-248 mesenteries provides support structure for blood vessels and nerve leading to all the abdominal organs villi (villus) absorbs nutrients and water from digested food 6- IMPORTANCE OF SURFACE AREA pg. 248-250 microvilli increases surface area of the cells lacteals absorbs nutrients and water from digested food 7-EARTHWORM LOCOMOTION pg. 251-252 circular muscle controls the flow of food and liquid longitudinal muscle pushing digested material to the rectum peristalsis moves swallowed food down the stomach smooth muscle tissue controls voluntary contractions skeletal muscle tissue enables movement by contracting and pulling on bones cardiac muscle tissue pumps blood around the body
