Cards

Term
Interstitial Fluid
Definition
Outside of Cells
15% of total body weight
Composition Similar to Blood Plasma
Term
Artery
Definition
Delivers Oxygen and Nutrients to Cell
High O2, low CO2
Under High Pressure
Term
Capillary
Definition
Tiny blood vessels, site of exchange of nutrient and what have you
Term
Vein
Definition
Carries blood containing waste products from cell toward the heart
Low O2, High CO2
Low Pressure
Term
Lymphatic Circulation
Definition
Blind Ended Capillaries absorb excess fluid and recycle it into large veins
Term
Superior & Inferior Venae Cavae
Definition
Largest veins - superior goes into the top of the heart, inferior the bottom
Term
Pulmonary Circulation towards Lungs
Definition
Pulmonary Trunk > Pulmonary Arteries > Lungs
low O2 high CO2
Term
Pulmonary Circulation away from Lungs
Definition
Lungs > Pulmonary Veins > Heart
High O2, Low CO2
Term
Aorta
Definition
Largest Artery (is in the heart)
Term
Coronary Arteries
Definition
Surround the heart
deliver blood to myocardium (heart muscle)
Term
Systemic Circulation
Definition
All circulation that isn't pulmonary (the whole rest of the body)
Term
Carotid Arteries
Definition
to brain
Term
baroreceptors
Definition
In carotid sinuses, detect changes in blood pressure
Term
chemoreceptors
Definition
in carotid bodies, detect changes in blood pH
Term
Hypothalamus
Definition
5 functions
temperature
water balance
autonomics
hormone production - ADH and Oxytocin, also releases releasing and inhibiting hormones for Anterior Pituitary
Term
HHPS
Definition
Hypothalamic Hypophyseal Portal System
Capillary - Vein - Capillary
Term
Adenohypophysis
Definition
Anterior Pituitary gland
releases: FSH (Follicle Stimulating) LH (Leutanizing) TSH (Thyroid Stimulating) GH (Growth) PRL (Prolactin) ACTH (Adrenocorticotropic)
Term
Dural Sinuses
Definition
Drain Blood from Brain
> Jugular Vein > Superior Venae Cavae > Heart
Term
Hepatic Artery
Definition
Branch of descending aorta, going to liver
Term
Sinusoids
Definition
Leaky Blood Capillaries (weird shaped, looks like coral)
surrounded by Hepatocytes
Term
Kupffer Cells
Definition
Macrophages inside liver
Term
Pancreatic Artery
Definition
Branch of descending aorta, going to pancreas
Term
Pancreas
Definition
Mixed gland - has both endocrine and exocrine function
Term
Exocrine
Definition
Digestive Enzymes + sodium bicarbonate
empty into pancreatic duct > small intestine
Term
Endocrine
Definition
Hormones: insulin + Glucagon! are the big two
also ghrelin, pancreatic polypeptide, and sematostatin
are secreted into pancreatic vein > HPV (hepatic portal vein)
Term
Splenic Artery
Definition
goes to Spleen
Term
Spleen
Definition
has Macrophages and Lymphocytes for Defense
Recycles old red blood cells
Term
Red Blood Cell Recycling
Definition
Hemoglobin > Heme (red pigment) > Fe 2+
> bilirubin > splenic vein >hpv
> Globin (protein) > amino acids > splenic vein >hpv
Term
Hepatic Portal Vein
Definition
HPV - Venous vein from pancreas, spleen, and digestive organs delivered to liver
Term
Functions of Liver
Definition
1. Processes glucose into Glycogen
2. Produces Plasma Proteins
3. Stores vitamins ADEK
4. Bile production (bilirubin + cholesterol)
5. Stores Fe 2+
6. Phagocytosis by macrophages
7. Detoxifies drugs and Alcohol
Term
Hepatic Duct
Definition
drains bile from liver into gall bladder
Term
Cystic Duct
Definition
drains bile from gall bladder
Term
Common Bile Duct
Definition
Cystic + Hepatic Duct
takes digestive enzymes & bile from pancreas > common bile duct > small intestine
function: digestion of food
Term
Hepatic Vein
Definition
Drains the blood from the liver. Blood is cleansed and Nutrient Rich
Term
Renal Arteries
Definition
Go to Kidneys
Term
Kidney Functions
Definition
Urine Formation - removal of nitrogen waste products, water and electrolyte balance
Blood Pressure regulation - adjusts volume of water and Na, secretion of renin
Production of Erythroproietin (hormone) - stimulates RBC production
Term
Bone functions
Definition
stores Ca 2+, produces RBCs
Term
Arterial Supply to Reproductive Organs
Definition
may contain FSH, LH
Term
Venous Drainage from Reproductive Organs
Definition
may contain estrogen, progesterone, testosterone
Term
Blood supply to Skin
Definition
peripheral circulation regulated by temperature needs and sympathetic NS
Term
lymphatic organs functions
Definition
DEFENSE
phagocytosis, production of antibodies
Term
Lymphatic circulation
Definition
filters and destroys pathogens
recycles excess fluids into blood circulation
Term
Blood Matrix
Definition
Blood Plasma - 55% of blood volume
composed of H2O, electrolytes, hormones, antibodies, nutrients
Term
Red Blood Cells
Definition
4-6 million per millimeter cubed (KNOW THIS)
carry oxygen, bound to hemoglobin
Term
Hemoglobin
Definition
Red Pigment
14-18 gram/100 ml in men
12-16 gram/100 ml in women
Term
Platelets
Definition
Function: clot formation
150k-450k / mm^3
Term
white blood cells
Definition
Function: defense
4k-11k /mm^3
