- Jugular veins?
- drain blood from brain
-
Blind-ended capillaries,
(Lymphatic circulation)
-
absorb excaess fluid & empty it into systemic circulation
(one direction, towards the heart) -
Hemoglobin Breakdown
(diagram) - diagram:
- Systemic circulation (rest of body that lymphatic and pulmonary don't get)
-
carotid arties to brain
baroreceptors detect changes in bp
-carotid sinuses
chemoreceptors detect changes in pH
-carotid bodies - Hepatic vein
-
drains blood from liver
blood is:
-cleansed
-nutrient enriched - Aorta
- largest artery
- Arterial supply to the bones
- Bone stores Ca, & produces blood cells
- Hypothalamic Hypophyseal Portal System (HHPS)
- portal system = capillary -> vein -> capillary
- Venous drainage to reproductive organs
- blood contains estrogen, progesterone, & testosterone (depending if male or female)
- Adenohypophysis
-
(anterior putitary gland)
hormones: ACTH, FSH, LH, GH, TSH, PRL(prolactin)
hypothalamus stimulates these hormaones based on body needs - Pancreatic artery > Pancreas
- Pancreas-"mixed gland", both endo and exocrine funct.
- Blood Flow (to and from cell)
-
Artery- delivers oxygen & nutrients to cell
Capillary- site of exchange
Vein- drains blood w/ waste products to heart - Lymphatic circulation thru lymph nodes
-
-filters pathogens
-recycles excess fluids into blood circulation - Body Cell
- needed to maintain homeostasis
- Splenic artery > Spleen
-
-macrophages & lymphocytes for defense
- recycles old RBC's > 60-90 day life span - Superior and Inferior vena cavae
-
largest vein
low O2 high CO2 -
Renal arteries > kidneys
Funct. of Kidneys -
- urine formation
removal of Nit. wastes products
H2O & electrolyte balance
-blood pressure reg.
vol. of H2O & Na
secretion of renin
-Erythropoietin -hormone that stim. RBC production - Hypothalamus
-
produce hormones
-ADH, Oxytocin
(releasing and inhibiting)
water and temp. balance - Hepatic Duct
- drains bile form liver into gall bladder
- Coronary arteries
-
deliver blood to myocardium (heart muscle)
coronary artery disease- hardening of arteries; makes it hard to pass blood -> heart attack - Hepatic Artery > Liver
-
Sinusoids- leaky blood
capillaries
macrophages(Kupffer cells)
surrounded by
hepatocytes (liver cells) - Pulmonary circulation
-
pulmonary trunk > pulmonary arteries > lungs
low O2 high CO2
lungs > pulmonary veins > heart
high O2 low CO2 - renal veins
- drain blood from kidneys
- Interstitial fluid
-
-15% of total body weight
- composition similar to plasma - renin
- produce in response to low bp
- Exocrine (duct)
-
secreted into pancreatic duct > small intestine
-digestive enzymes and sodium barcarbonate produced - Arterial supply to reproductive organs
- blood contains FSH & LH
- Blood supply to the Lymphatic organs
-
FUNCT.
-defense, fight disease
1. phagocytosis
2. production of antibodies - Endocrine Organs
- arterial & venous circulation to all endocrine organs produce & release hormones
- Cystic Duct
-
drains bile from gall bladder
cystic duct + hepatic duct = common bile duct
pancreatic digestive enzymes & bile ->common bile duct -> sm. intestines (funct. food digestion) - Endocrine (no duct)
-
secreted into pancreatic duct > HPV
(2 hormones produced
in pancreas: insulin
and glucagon) - Hepatic Portal Vein (HPV)
- venous blood from pancreas, spleen and digestive organs delivered to liver
- Funct. of Liver
-
-process glucose into glycogen
-produce plasma proteins (a.a) -> clotting factors, transport
-stores fat-soluble vitamins (ADEK)
-bile production (bilirubin & cholesterol)
-stores Fe
-phagocytosis by macrophages
-detoxifies drugs & alcohol - Arteries to GI tract
-
digestion- breakdown of food into nutirents
absorption- movement of nutrients from digestive tract into bloodstream - Venous drainage from muscle
- waste products from muscle metabolism; CO2, heat, latic acid
- lymph nodes
-
collection of lymphcytes (WBC)
located in othe areas of the body besides the neck
