Everything Flashcards
Facilitated diffusion
Movement of molecules with the help of a carrier protein
Diffusion
Movement of molecules from an area of high solute concentration to low solute concentration.
Osmosis
Movement of water through a membrane from an area of low solute concentration to high solute concentration
Filtration
Movement of fluid through a membrane when the pressure on one side is greater than the other
Arteries
High degree if elastic tissue in walls, carries blood away from heart, can feel pulse
Veins
Carries blood to heart, some rely on skeletal muscle contraction and valves to move blood along.
Capillaries
Site of gas exchange at tissue level and at alveoli in lungs
Ventricular depolarization and atrial repolarization
QRS complex
Ventricular repolarozation
T wave
Atrial depolarization
P wave
Loop of Henle
Long tubule from which some H2O, Na+, and Cl- are reabsorbed
Glomerulus
Specialized capillaries for filtration
Bowman’s Capsule
Receives filtrate from blood
Proximal convulated tubules
Main site of absorption of H2O, glucose, etc.
Peritubular capillaries
Capillaries where electrolytes are reabsorbed
Distal convulated tubules
Main site for secretion
ACTH
Anterior pituitary to adrenal cortex
Insulin
Causes decrease in blood glucose
Glucagon
Causes increase in blood glucose
Aldosterone
Causes reabsorption of salt in kidneys
ADH
Causes reabsorption of water in kidneys
Anestrus
Temporary ovarian inactivity
Proestrus
Follicular development, rising estrogen
Estrus
Sexual receptivity, peak estrogen
Metestrus
Development of corpus luteum after ovulation
Diestrus
Luteal stage, high progesterone level
Hemoglobin
The largest molecule in blood and the main transport for oxygen
Tendon
Attaches muscle to bone
Ligament
Structure that attaches bone to bone
Glycogen
Storage form of glucose in liver
Lactic acid
By product of anaerobic muscle metabolism
Synapse
Name for the junction between two neurons or between a neuron and a muscle cell
Neurotransmitter
General word used for substances that are released to cross a synaptic cleft and cause communication between two neurons or between a neuron or a muscle cell.
Periosteum
Fibrous connective tissue that surrounds the shafts of long bones
Parathormone
Hormone that increases blood calcium
Calcium
Ion that moves into the end of the neuron in response to depolarization and causes release of a neurotransmitter
Glucose and oxygen
Two most important substances required for the brains metabolic needs
Nervous and endocrine
Two systems that are responsible for homeostasis
Three types of muscle
Smooth, skeletal, cardiac
Functions of kidney
Urine formation, hormone production, fluid balance, and pH balance
Four ways integument changes to conserve body heat
Fat storage, heavier coat, erector pili muscle contraction, and capillary constriction
Three sites to take a pulse on cat or dog
Femoral artery, lingual artery, and pedal artery
Three substances secreted by stomach
Hydrochloridc acid, pepsinogen, and mucus
Striated muscles
Located in heart and skeletal muscles
Where is the SA node located?
The right atrium
Sensory nerves are considered…
Afferent nerves

Hilus
Entrance/exit for vessels, nerves, and the ureter
Calyx
Funnel that directs urine into the renal pelvis
Ureter
Carries urine to the bladder
Nephron
