HEART & BLOOD HEART & BLOOD VESSELSVESSELS (Angiolog(Angiologyy))
Is the description of the organs of circulation of the blood & lymph, the heart and vessels, including the spleen and thymus.
cardiovasculer system: heart ( latin :COR) blood vessels: arteries & capillaries, veins
Lymphatic system : lymphatic organ lymph nodes lymph vessels

Is the fibroserous sac which encloses the heart, in part, great vessels connected with it.
fibrous layer (pericardium fibrosum): relative thin, but strong and inelastic.
pericardium serosum : is a closed sac, surrounded by the fibrous pericardium and invaginated by the heart. It is smooth and glistening and contain a small amount of clear serous fluid : liqour pericardii. Pericardium visceralis/lamina visceralis/epicardium Pericardium parietalis/lamina parietalis
Pericardium visceralis : covers the heart and parts of the great vessels.
Pericardium parietalis : lines the fibrous layer, to which it is closely attached.

PERICARDIUM
• It is attached dorsally to the large vessels at the base of the heart and is continued in part up to the longus colli muscle.
• Ligamentum sternopericardiaca : it is a strong ligament attached the pericardium ventrally to the middle of the caudal half of the thoracic surface of the sternum. ( in cattle, horse and swine) and in carnivore by a phrenopericardiac ligament to the diaphragm.

BLOOD VESSELSBLOOD VESSELS• Arteri :
– Leave he heart,– recieve & sent the blood from the heart to the tissue– contain of O2 except in the arteria Pulmonalis– position : usually more deeper than vena (profunda)– Structure : more elastic than vena– the pressure more stronger than venae
• Vena : – the blood go to he heart.– Receive blood from the tissue and send to the heart– contain metabolism product (especially CO2) except
v.pulmonalis– location : more superficial – have valve– Structure : the wall is thinner and not elastic – the pressure is weaker
![Page 12: HEART & BLOOD VESSELS ( Angiolog y )](https://reader030.vdocuments.mx/reader030/viewer/2022012908/56814e00550346895dbb6b91/html5/thumbnails/12.jpg)
• The wall of the blood vessel compose of : – First layer : tunica interna/intima :
• Endothel
• Membrane elastica interna (subendothel)
– Second layer : tunica media : • thicker part, contain elastic tissue and smooth muscle
– Third layer: tunica adventitia : • Compose of fibrous and fibroareolar tissue

VeinVein
valve
Most veins are also distinguish by the presence of valves, which are repeated at intervalalong their length; the valves ensure a unidirectional flow and prevent reflux of blood when the circulation stagnates.Each valve consists of two or three semilunar cusps facing each other
arrow indicates the direction of blood flow.

BLOOD VESSEL COMPOSITIONBLOOD VESSEL COMPOSITION
Artery : Aorta Artery Arteriol capiler Sinusoid
Vein : vein Venule
according to the thickness of the tunica media ( elastic tissue) : the smaller the diameter of the blood vessel, tunica media become thinner and thinner
![Page 16: HEART & BLOOD VESSELS ( Angiolog y )](https://reader030.vdocuments.mx/reader030/viewer/2022012908/56814e00550346895dbb6b91/html5/thumbnails/16.jpg)
Artery : – Aorta : the biggest diameter , leave the cor,
accept the sistolic output from ventricle – Artery : branch of the aorta
– Arteriol : smaller diameter, a litter bigger than capiler, function to adjust blood stream and to pump the perifer blood.
– Capiler : Endothel is thin Supporting tissue is thinner too, Place for the blood enter to the interstitial tissue Parts of the liquid which contain metabolic waste is
absorbed by venule.
On special organ, endothelial capiler which enter to the organ have pore. Ex : on the intestine villi and glomerulus
![Page 17: HEART & BLOOD VESSELS ( Angiolog y )](https://reader030.vdocuments.mx/reader030/viewer/2022012908/56814e00550346895dbb6b91/html5/thumbnails/17.jpg)
ARTERIES
the arteries may be distinguished from other vessels by their white, thick, and relatively rigid walls and their empty lumen (unless filled with an injection mass for the convenience of the dissector).
![Page 18: HEART & BLOOD VESSELS ( Angiolog y )](https://reader030.vdocuments.mx/reader030/viewer/2022012908/56814e00550346895dbb6b91/html5/thumbnails/18.jpg)
Sinusoid : parts of the capiler which can be find in special organs. Ex: lever, spleen and medulla spinalis.
specificity: usually inside the organs Vein :
Vein : thinner wall, their frequently collapsed appearance, and their capacity, which is invariably greater than that of the associated arteries. in the large diameter of the vena the anatomic structure almost the same as the arteri.
Very largest arteries and veins run separately, but most veins of medium and lesser size accompany the corresponding arteries to which they are said to be satellite
Venule : vena ending, smallest vena, tunica interna always thin and do not have membrane elastic interna
![Page 19: HEART & BLOOD VESSELS ( Angiolog y )](https://reader030.vdocuments.mx/reader030/viewer/2022012908/56814e00550346895dbb6b91/html5/thumbnails/19.jpg)

• Anastomose : direct connection between arteri and vein without passing the capiler in order to shorten the connection between arteri and vein,
• Fx : – Passing the blood stream from the arteri in order do
not go in to the tissue, when the tissue is rest. • ex : mucosa of the gaster
– Thermo regulator • ex: ears, nose and digits (fingers or toes)
• Collateral circulation : direct connection between artery and artery
• Fx :– efisiency, the blood can reach target organ on time
in order to avoid ischemia necrotic

Blood vessel nutrition
• Blood vessel wall need a nutrition :– In small blood vessel : nutrition is enough
from the difusion inside the blood vessel lumen.
– In the larger blood vessel : nutrition is helped by the blood vessel which surrounding by the target blood vessel: Vasa vasorum

Heart Heart vvasasccularisaularisattiionon
• The heart get nutrition from the blood vessel on the cor.• Left ventrikel , blood go to the aorta. In the dorsal part
aorta give a branch term: a. coronaria• Heart receive ±15% blood supply from the a. coronaria• A. coronaria divide into 2 :
– (i) a. coronaria sinistra also term as ramus interventrikularis paraconal
– (ii) a. coronaria dekstra also term as ramus interventrikularis subsinuosal

• Arteri and vena are innervated by motoric and sensoric nerves
• nerve motoric useful for control enlarger and narrower blood vessel lumen
• Sensoric nerve, nerve endings for the response of the pressure change in O2-CO2 and the consentration of Hidrogen ion (H+) in the blood stream.

• Foetus receive blood which contain oksigen, nutrition and expel metabolism product through : placenta
• Foetus stage, pulmonary circulation is undeveloped• Blood stream which enter to the trunchus
pulmonalis mostly through ductus arteriosus, and go to the aorta, only a small part go in the lung through a. pulmonalis
• Directly after the birth ductus arteriosus is rudimenter and chance become : ligamentum arteriosum, consequently the lungs receive all of the blood from a. pulmonalis, and the lung function is became perfectly.
![Page 32: HEART & BLOOD VESSELS ( Angiolog y )](https://reader030.vdocuments.mx/reader030/viewer/2022012908/56814e00550346895dbb6b91/html5/thumbnails/32.jpg)
• There is a hole in the septum atrium between right and left atrium, term : foramen ovale
• After birth, foramen ovale is closed. In this foramen ovale there is a mark : Fossa ovalis
• V. umbilicalis : receive blood which contain oksigen from the placenta . There is no valve.
• A. umbilicalis receive blood which contain metabolism waste product especially CO2 from the whole body and delivery back to the mother placenta.

empties into the cranial vena cava at thoracic inlet.• The tip of the blind capiler and their wall is easy
exceeded by a substance which come from inside and outside the tissue
• Permeability more bigger than blood vessels (cause membran basalis is not completed develop)
• In the larger lymphe duct has a valve: lymphangions • lymphe liquid stream from the tissue go to the vein
because of the pressure outside the vessels. Ex : peristaltic intestine, movement of the extremity or
tension skin and movement of lymphe valve

lymph lymph
• Collecting the liquid from the tissue as metabolit product in cells and tissue
• lymph is a clear colorless fluid except in the intestine vessels in which, after digestion, it is milky in color and term : chyle
• In general, the composition of lymph fluid almost the same as blood plasma.
• lymphe liquid from liver has protein content most higher.
• Lymphe liquid from the skin has the lowest protein content.

PProduction ofroduction of lymphe lymphe liquidliquid : :
• Cells activity produce metabolit2 → • cause hiperemia, permeability increase,
capiler pressure increase → • Liquid from the blood vessels go outside →
enter the tissue → • tissue edema →force endothel cells → • capiler lymphe vessels open →• lymphe liquid in the capiler drain to the next
vessels.

– In the periosteum and endosteum of the bones and follow Haversian canals.
– No in the cartilage and medulla spinalis
• muscles:– In the perimysium external and under the fascia– In the endomysium muscles, capiler lymph spread
between muscle fibers– In the synovialis bursae
2. alimentary organ :– In the subserous and submucuos layers

Cisterna chyli
• Is located as an elongated, irregular, sac-like dilatation of a large lymph trunk between the right side of the aorta and the right crus of the diaphragm, extending from the second or third lumbal vertebrae to the last thoracic vert.
• Receive the lumbar and intestinal trunks at its caudal portion while the celiac trunk terminates in its cranial half

Ductus thoracicus
• Is the extension of the cisterna chyli into the thoracic cavity through aortic hiatus and run craniad on the right side of the median plane between the right vena azygos and aorta, covered by pleura.
• Its opens into the dorsal part of the origin of the cranial vena cava
