BBlood Vessels LAB Flashcards
Do arteries have higher blood pressure than viens?
YES
Arteries walls are thicker
Yes
What vessel Provide nutrients, water, O2 to cells
and Pick up CO2 & waste from cells?
Capillaries
Superficial veins contain valves
TRUE
Veins Begin as venules on return to heart.
TRUE.
What blood vessel walls are made up of connective tissue ?
Tunica Externa
What blood vessel wall is thicker in arteries?
Tunica media
What blood vessel wall is made up of thin layer of connective tissue and thin layer of simple squamous epithelium, endothelium, closest to blood??
Tunica Interna
What are blood vessel that nourish other vessels?
Vasa Vasorum
What circuit is pulmonary trunk, L&R pulmonary arteries, lobar arteries, capillaries ?
Pulmonary Circuit
Lungs in the blood is oxygenated and what is released?
Carbon dioxide
From the aortic arch, Brachiocephalic trunk divides into
Right common carotid and right subclavian
Common carotid arteries branch into what ?
External carotid (supplies blood to face)
Internal carotid: passes through carotid canal. (supplies blood to brain)
What artery receives blood from subclavian arteries?
Vertebral Arteries
With internal carotids what else supplies blood to the brain?
Vertebral arteries
Vertebral arteries: basilar, cerebellar, arterial circle all do what?
Supply blood to brain.
Internal Carotid arteries: arterial circle, cerebral (take blood to surface of cerebrum & inferior of brain) all do what?
Supply blood to the brain.
Veins travel through subarachnoid space to
Venous sinuses
From venous sinuses, what other two parts does the blood travel through?
Internal jugular veins and brachiocephalic vein
Blood from superficial region of head travel through
external jugular veins
Left and right subclavian take blood to
Superior vena cava
Arteries of thorax supply blood superior to
diaphragm
posterior intercostal arteries supply blood to
Intercostal muscles and vertebrae.
Internal thoracic artery supplies to
Anterior intercostal arteries , pericardium, diaphragm
Large veins of thorax are
Subclavian, brachiocephalic, superior vena cava
Primary drainage veins of thorax are
Azygos (R) and hemiazygos (l)
Arteries of anterior abdomen
celiac trunk/ artery
Splenic (to spleen pancreas), Left gastric ( to stomach & esophagus)
Common hepatic artery (liver, stomach, pancreas)
Arteries of middle abdomen
Superior Mesenteric artery: to small intestine, cecum, ascending colon and part of transverse colon
Arteries of lower abdomen and iliac arteries
- Suprarenal arteries (L&R) to (adrenal gland)
- Renal Arteries (L & R) to (kidneys)
- Gonadal Arteries to (testis or ovaries)
- Inferior Mesenteric Artery to (part of transverse colon, descending colon, sigmoid colon, & rectum)
Common Iliac Arteries (lower limb)
Common Iliac Arteries (L&R) divide into internal & external iliac arteries
Internal Iliac Arteries ( to pelvis, rectum, pelvic floor, external genitalia, groin muscles hip muscles, uterus, ovary, vagina )
Hepatic Portal System
Blood from capillaries of abdominal organs travels through veins to another capillary system in
liver before going to heart
Veins in hepatic portal system
- Inferior Mesenteric Vein (drains distal Large Intestine)
also receives blood from…
2) Right Gastro-omental Vein empties into…
3) Splenic Vein
4) Splenic Joins with Superior Mesenteric Vein (which drains
the small intestine & proximal large intestine) forming…
5) Hepatic Portal Vein
Hepatic Portal Vein takes blood to capillaries of Liver
* Blood is cleaned by macrophages
* Nutrients stored in liver or pass into bloodstream
Hepatic Veins bring blood from liver to
Inferior Vena Cava
Abdominal and pelvic veins
Some abdominal veins take blood directly to Inferior Vena Cava
* Renal Veins
* L Gonadal drains into
Renal
* Suprarenal Veins
* Lumbar Veins
* Right Gonadal
Femoral vein drains into
External iliac vein
External iliac vein joins
Internal iliac vein which forms common iliac vein
L&R common iliac veins unite to form
Inferior vena cava
