3 bones within the nasal cavity that are covered with mucus
External vs. Internal Intercoastal Muscles
External: Raise Ribcage
Internal: Lower Ribcage
Air Pathway (Inhalation)
Nasal Cavity--> Pharynx-->Glottis-->Larynx-->Bronchi-->Bronchioles-->alveoli
Thin Respiratory Membrane
Alveolar Epithelium + Pulmonary Endothelium + basement membranes
Water and Solutes added by...
-Absorption from liquid and solid foods in digestive tract
-Metabolism
-Respiration
Water and Solutes Lost by...
-Urinary Excretion
-Evaporation from Respiratory Surfaces
-Sweat (mainly comp. of water)
-Elimination in feces
Kidneys are composed of what?
A cortex and a Medulla
Ureter
Tubular channel between the kidney and urinary bladder
Urethra
Muscular Tube leading FROM bladder TO outside of body!
Nephron is where?
Kidney! (basic functional unit)
How does filtrate flow through the nephron?
(glomerulus) then STARTS AT BOWMANS capsule...-->PCT-->Loop of Henle-->DCT-->Collecting Duct-->Renal Pelvis-->(then Ureter, Bladder, Urethra)
What are the things that surround the nephron?
Peritubular Capillaries
Filtration
OUT of the glomular capillaries INTO the nephron
Reabsorption
OUT of nephron INTO peritubular capillaries (back into circulation)
Can't produce antidiuretic hormone?
Diabetes Insipidus
Where does filtration take place?
Bowman's capsule
Where does secretion take place?
DCT
Secretion
OUT of peritubular capillaries INTO the nephron
Excretion
Collecting duct to the renal pelvis then the urinary tract (ureter, bladder, urethra)
**Only subs. that were not reabsorbed or were secreted into the tubule!
Sweat Glands
release water and some solutes (urea) through pores at the skin's surface
Large Intestine
Removes salts like calcium and heavy metals like lead and mercury
Liver
Receives ammonia from the blood and converts it to urea; also breaks down toxins.
Lungs
Remove CO2, water, and alcohol from the blood
