Important remarks about directions
➢ Directions are mostly compared to each other: superior vein and inferior vein
➔ Lateral compared to medial -> peripheral to central
➔ Ventral compared to dorsal
➔ Distal compared to Proximal
➔ Anterior compared to posterior
➔ Superficial compared to deep
! Remember in animals walking on 4 legs cranial doesn’t mean the same as in
humans; their head then is referred to as anterior

, ➔ Tricuspid valve = right atrioventricular
valve -> atria to ventricle
➔ Bicuspid valve (mitral valve) = left
side -> left atrioventricular valve
➔ Sinus coronarius = drains venous
blood from coronary circulation to the
right atrium of the heart
Signal transduction heart

, Circulatory system
➢ Arteries ALWAYS carry blood away from the heart (mostly oxygenated but not
always)
➔ Pulmonary arteries: heart to the lungs
➔ Umbilical arteries: fetus to the maternal placenta
➢ Veins carry blood to the heart (mostly deoxygenated but not always)
➔ Pulmonary veins: lungs to the heart
➔ Umbilical veins: placenta to the fetus
Microvasculature versus macrovasculature
➢ Large vessels versus capillaries, arterioles, and venules
Branches from aorta
1 branchiolic artery
2 common carotid artery
3 subclavian artery (either left or right)
Function circulatory system
- Heat exchange, nutrient delivery, ‘waste pick-up’, brings oxygen, hormone
delivery
➔ Exchange finds place in capillaries (only one cell thick)
Structure of a blood vessel
1. Tunica intima -> one layer of endothelium
on basal lamina, supported by
subendothelial connective tissue; in
arteries the lamina elastica interna
separates layers (visible as wavy line)
2. Tunica media -> layers of smooth muscle
cells separated by ECF (proteoglycans); in
large vessels a lamina elastica interna
separates from next layer
3. Adventitial layer -> connective tissue
(collagenous and elastic fibers), blends in
with connective from organ it is imbedded
in
4. Vas vasorum -> in large vessels vas
vasorum supply vessel wall with blood
➔ Lymph vessels and vasomotor nerves
can be found in the connective tissue
