Blood vessels

What are the 5 main functions for blood vessels?

1)Acts as delivery system,2)regulate b\p,3)engage of enchange of nutrients and waste between the capillariteis and cells,4)redistribute blood is response to changing body needs 5) regulate body tempeture

branches of descending aorta abdominal aorta

3 single anterior visceral branches (coeliac, superior mesenteric artery, inferior mesenteric artery) 3 paired lateral visceral branches (suprarenal, renal, gonadal) 5 paired lateral abdominal wall branches (inferior phrenic and four lumbar)The abdominal aorta supplies oxygenated blood to all of the abdominal and pelvic organs and the legs.

Internal Jugular Vein

A large and deep vein that parallels the common carotid artery, deep to sternocleidomastoid.

what are thin capillary walls

A single capillary is so small that it allows only one blood cell to flow through it at a time. The capillary walls are also very small, only one cell thick. These thin walls easily allow water, oxygen, carbon dioxide, and other nutrient and waste substances to exchange between blood cells and the surrounding tissue

functions of venules

A venule is a small blood vessel in the microcirculation that allows deoxygenated blood to return from capillary beds to larger blood vessels called veins. Venules range from 8 to 100μm in diameter and are formed when capillaries come together. Many venules unite to form a vein.

Which molecules would increase blood pressure by increasing the volume of blood?

ADH Aldosterone

The purpose of the fetal circulation is to keep blood

Away from the lungs

In order to transport CO2 in the blood, we turn it into which substance?

Bicarbonate

Blood Supply to the Head and Neck

Blood circulates from the upper systemic loop originating at the aortic arch, and includes: the brachiocephalic artery, left common carotid artery and left subclavian artery. The head and neck are emptied of blood by the subclavian vein and jugular vein.

blood supply to head and brain

Blood is supplied to the brain, face, and scalp via two major sets of vessels: the right and left common carotid arteries and the right and left vertebral arteries. The common carotid arteries have two divisions. The external carotid arteries supply the face and scalp with blood.

blocked lymphatic drainage

Blood vessels are key components of the systemic and pulmonary circulatory systems that distribute blood throughout the body. Capillaries in turn merge into venules, then into larger veins responsible for returning the blood to the heart. The junctions between vessels are called anastomoses.

What are arteries?

Blood vessels that carry blood away from the heart.

exchange involving filtration osmosis

CHP is the force that drives fluid out of capillaries and into the tissues. As fluid exits a capillary and moves into tissues, the hydrostatic pressure in the interstitial fluid correspondingly rises. ... Thus, fluid generally moves out of the capillary and into the interstitial fluid. This process is called filtration.

What can be found in the water that returns into the bloodstream from the cells?

CO2 Waste

The smallest and most numerous blood vessel in our body are

Capillaries

what is exchange vessel

Capillaries are tiny vessels that connect arterioles to venules. They have very thin walls which allow nutrients from the blood to pass into the body tissues. Waste products from body tissues can also pass into the capillaries

Capillary exchange

Capillary exchange refers to the exchange of material from the blood into the tissues in the capillary. Hydrostatic pressure is a force generated by the pressure of fluid on the capillary walls either by the blood plasma or interstitial fluid.

capillary forces exchange

Capillary exchange refers to the exchange of material from the blood into the tissues in the capillary. There are three mechanisms that facilitate capillary exchange: diffusion, transcytosis and bulk flow.

kidney disease

Chronic kidney disease, also called chronic kidney failure, describes the gradual loss of kidney function.

exchange involving diffusion

Diffusion, the most widely-used mechanism, allows the flow of small molecules across capillaries such as glucose and oxygen from the blood into the tissues and carbon dioxide from the tissue into the blood.

The hole connecting the babies "two large arteries" leaving the heart is called:

Ductus arteriosus

Which molecules would increase blood pressure by contracting the smooth muscle?

fetal circulation

Fetal Circulation. The blood that flows through the fetus is actually more complicated than after the baby is born (normal heart). ... The placenta accepts the bluest blood (blood without oxygen) from the fetus through blood vessels that leave the fetus through the umbilical cord (umbilical arteries, there are two of them)

What is the process called at the capillaries when water leaves the bloodstream to our surrounding cells?

Filtration

The hole connecting the babies two atria is called:

Foramen ovale

What is heart failure?

Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. In some cases, the heart can't fill with enough blood. In other cases, the heart can't pump blood to the rest of the body with enough force

The liver is a "special circulation" because he has an extra blood vessel called the

Hepatic portal vein

blood supply to liver and hepatic portal circulation

In the hepatic portal system, the liver receives a dual blood supply from the hepatic portal vein and hepatic arteries. The hepatic portal vein carries venous blood drained from the spleen, gastrointestinal tract and its associated organs; it supplies approximately 75% of the liver's blood.

how does the peripheral blood vessels affect the blood pressure

Increases in peripheral resistance, blood volume, and cardiac output result in higher blood pressure. Conversely decreases in any of these factors lead to lower blood pressure. Three main sources of peripheral resistance: Blood vessel diameter, blood viscosity, and total vessel length

Which blood vessels make up the brain's special circulation?

Internal carotid arteries Vertebral arteries

venous drainage of head and brain

It exits the skull via the jugular foramen. ... During its descent down the neck, the internal jugular vein receives blood from the facial, lingual, occipital, superior and middle thyroid veins. These veins drain blood from the anterior face, trachea, thyroid, oesophagus, larynx, and muscles of the neck.

Azygos Vein

Merges with the superior vena cava in proximity to the right atrium, receives blood from the posterior thoracic region.

The jugular veins are veins that take deoxygenated blood from the head back to the heart via the superior vena cava.

heaptic blood vessesls

The liver is connected to two large blood vessels, the hepatic artery and the portal vein. The hepatic artery carries blood from the aorta to the liver, whereas the portal vein carries blood containing the digested nutrients from the entire gastrointestinal tract, and also from the spleen and pancreas to the liver.

ascending aorta

The only branches of the ascending aorta are the two coronary arteries which supply the heart; they arise near the commencement of the aorta from the aortic sinuses which are opposite the aortic valve.The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood. The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms

umbilical arteries

The umbilical artery (latin: arteria umbilicalis) is a branch of the anterior division of the internal iliac artery that functions only in the time of the placental blood circulation.

umbillical vein

The umbilical vein is a vein present during fetal development that carries oxygenated blood from the placenta into the growing fetus. The umbilical vein provides convenient access to the central circulation of a neonate for restoration of blood volume and for administration of glucose and drugs.

Function of veins

They are responsible for returning deoxygenated blood back to the heart after arteries carry blood out. The vena cava is the largest vein in the body. Veins have much thinner walls than arteries.z

descending aorta thorarcic aorta

Three vessels come out of the aortic arch: the brachiocephalic artery, the left common carotid artery, and the left subclavian artery. These vessels supply blood to the head, neck, thorax and upper limbs. Behind the descending thoracic aorta is the vertebral column and the hemiazygos vein.The descending thoracic aorta travels down through the chest. Its small branches supply blood to the ribs and some chest structures
