lab 10: digestive, urinary and reproductive systems Flashcards
7 essential processes of digestion
Ingestion Mastication Digestion Secretion Absorption Compaction Excretion
3 layers of the mucosa
- mocosal epithelium: stratified or simple epithelium
- lamina propria: areolar tissue
- muscularis mucosae: smooth muscle and elastic fibers
what type of tissue is the submucosa made of
dense irregular tissue
muscular layer made of what tissue
smooth muscle
serosa made of 2 types of tissues
mesothelium (simple squamous) and loose connective tissue
what divisions of the nervous system innervate smooth muscle tissue
sympathetic and parasympathetic division
smooth muscle vs skeletal muscle
smooth : single nuclei, shorter, small spindled branches, nonstriated
skeletal : multiple nuclei, long, large round cells, striated
what is a mesentary
fused, double sheets of peritoneal membrane that connects the visceral and parietal peritoneum.
what tissue lines the mouth and pharynx
stratified squamous epithelium
4 digestive functions of the mouth
sensory analysis, lubrication, mechanical processing, limited digestion
4 functions of the tongue
mechanical processing, manipulation, sensory analysis, secretion of mucins and enzymes
2 types of cells in salivary glands
serous secretory cells, mucous secretory cells
functions of the palate
raise of palate and pharyngeal wall
3 phases of swallowing
buccal phase, pharyngeal phase, esophageal phase
what is the opening in the diaphragm the esophagus passes through
esophageal hiatus
3 processes of the stomach
storage of food, mechanical breakdown, and chemical digestion
what tissue forms the mucosal epithelium in the stomach
simple columnar
3 functions of the greater omentum
protective padding, lipid energy reserve, insulation
3 features of the intestines that increase surface area
plicae circularis, intestinal villi, microvilli
function of lacteals
transport lipid-protein complexes to venous circulation
intestinal crypt functions
deep pockets where stem cell divine occurs
what happens in the duodenum
receives chyme and enzymes from pancreas and liver
what happens in the jejunum
bulk of chemical digestion and nutrient absorption
what controls movement through the small intestine
weak peristaltic contractions
3 functions of large intestine
reabsorption of water and electrolytes, absorption of vitamins, storing of fecal matter
mucosal epithelium in large intestine made of
simple columnar epithelium
function of the rectum
stores fecal matter
3 functions of the liver
metabolic regulation, hematological regulation, synthesis and secretion of bile
function of the common hepatic duct
collects and transports bile out of the liver to the duodenum
function of the gallbladder
stores and concentrates bile before secretion to small intestine
pancreas functions
producing digestive enzymes and buffers
renal corpuscle function
produces filtrate
proximal convoluted tubule function
reabsorption of water, ion, and organic material
nephron loop function
descending portion: water reabsorption
ascending portion: reabsorption of sodium and chloride
distal convoluted tubule function
secretes ions, acids, drugs and toxins
collecting system consists of … and its function is …
connecting tubules, collecting ducts, papillary ducts
function: final adjustments of osmotic concentration and volume
what is the glomerulus
a capillary network
7 functions of the urinary system
regulates plasma concentration of Na, K, Cl, and Ca, regulates blood volume and pressure, regulates blood pH, conserves nutrients, elimates metabolic waste
3 functions of the epididymus
monitors and adjusts composition of fluid, recycles damages sperms, stores sperms and facilitates maturation
what do ovaries produce
ova and hormones
broad ligament is made of
mesothelial cells
