What are the three layers of tissue making up blood vessels?
- Tunical adventitia: Outer coating
- Tunical media: smooth muscle and elastic tissue middle coating
- Tunica Intima: inner coating of endothelium
Name the sizes and types of veins from largest to smallest and give examples
- Large veins: Vena Cava
- medium-sized veins: fibular veins
- Small veins: veins in palms of hands
- Venules: slightly larger than capillaries. Untappable
- Capillary: form beds in every tissues in the body; only one blood cell in diameter and very fragile.
Name the sizes and types of arteries from largest to smallest and give examples
- Elastic arteries: largest and thickest: Aorta
- Muscular arteries/distributing: medium sized that go all over the body: brachial
- Small arteries: arteries in fingers and toes
- Aterioles: smallest arteries with three layers,
- Capillary's: very thin, one cell wide
Short answer: Be a drop of blood and go from the heart to the finger and back
Left ventricle of heart --> Ascending aorta --> aortic arch-->brachiocephalic artery--subclavian artery--axillary artery--brachial artery--radial and ulnar artery-->superficial and deep palmar arches --> digital arteries-->capillaries -->digital veins -->superficial and deep palmer arches veins -->basilic vien or radial and ulnar veins -->brachial veins (if radial or ulnar) OR axillary --> Axillary (if radial or ulnar to start)--subclavian vein-->brachiocephalic vein-->superior vena cava-->right atrium
Short answer: Be a drop of blood and go from the heart to a toe and back
Heart-->aortic arch--thoracic aorta-->descending aorta-->common iliac artery-->external iliac artery--->femoral artery-->popliteal artery-->tibial arteries-->lateral and medial plantar arteries/dorsalis pedis arteries-->digital arteries-->cappilaries-->digital viens-->dorsal and plantar veins-->fibular and tibial veins, great and small saphenous veins-->popliteal vein --> femoral vein>extrernal iliac vein common iliac vein --inferior vena cava--> heart
Short answer: Be a drop of blood and go from the heart to the colon and back
heart--->aortic arch--->thoracic aorta---->decending abdominal aorta---->interior mesenteric artery---->superior/inferior mesenteric vein---->hepatic portal vein-->liver--->hepatic veins---->inferior vena cava----->to right atrium
Short answer: Be a drop of blood and go from the heart to the kidneys and back
heart--> aortic arch-->thoracic aorta--->renal artery-->renal vein --->inferior vena cava --->heart
Short answer: Be a drop of blood and go from the heart to the brain and back (no pit stops!)
Left ventricle of heart --> Ascending aorta --> aortic arch-->brachiocephalic artery -->right common carotid artery --> right internal carotid artery--> Cerebral arterial circle -->Venous sinuses -->right internal jugular vein --> right brachiocephalic vein--> superior vena cava --> right atrium of heart
do it all again!
