- Figure 1. Extracranial arterial collateral circulation. Shown are anastomoses from the facial (a), maxillary (b), and middle meningeal (c) arteries to the ophthalmic artery and dural arteriolar anastomoses from the middle meningeal artery (d) and occipital artery through the mastoid foramen (e) and parietal foramen (f).enous collaterals augment drainage of cerebral blood flow when principal routes are occluded or venous hypertension ensues. The anatomy of venous collateral circulation is highly variable, allowing diversion of blood through numerous routes when exiting the brain (Figure 3).

- Secondary transport systems appear to cause efflux of small molecules and nonessential amino acids from the brain to the blood. Sodium ion transporters on the luminal membrane and Na,K-ATPase on the anti-luminal membrane account for movement of sodium from the blood to the brain. The large number of mitochondrias present in the brain endothelial cells provide energy for the function of this Na,K-ATPase.

Superior mesenteric artery syndrome The superior mesenteric artery is a large artery in the abdominal cavity that provides blood to the small intestine, cecum, and colon.The small intestine is the portion of the digestive system most responsible for absorption of nutrients from food into the bloodstream.uperior mesenteric artery syndrome (SMAS) is a digestive condition that occurs when the duodenum (the first part of the small intestine) is compressed between two arteries (the aorta and the superior mesenteric artery). This compression causes partial or complete blockage of the duodenum.

Function of the Small Intestine (Digestive System) 1 Sodium ions (Na +) move from the lumen of the small intestine into epithelial cells by diffusion and active transport. 2  They are then actively transported into blood capillaries on the other side of the epithelial cells. 3  Chloride (Cl -) can passively follow Na + ions into epithelial cells, or be actively transported.ost water-soluble vitamins (C and the B vitamins) are absorbed by diffusion. Vitamin B 12 combined with intrinsic factor (from the stomach) is absorbed by active transport. Most nutrients are absorbed in the jejunum.

Hepatic portal system The portal venous system is responsible for directing blood from parts of the gastrointestinal tract to the liver. Substances absorbed in the small intestine travel first to the liver for processing before continuing to the heart. Not all of the gastrointestinal tract is part of this system.

Anatomy of the Heart: Blood Flow and Parts First, blood from the body enters the right atrium and passively flows into the right ventricle through the AV valve called the tricuspid valve. This is the valve that separates the right atrium and the right ventricle, and its name comes from the fact that it has three flaps (or cusps) that open and close.

Foramen ovale (heart) The first is the foramen ovale which shunts blood from the right atrium to the left atrium. The second is the ductus arteriosus which shunts blood from the pulmonary artery (which, after birth, carries blood from the right side of the heart to the lungs) to the descending aorta.

Anterior cingulate cortex MeSH. [1]. The anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex, that resembles a collar form around the corpus callosum, the fibrous bundle that relays neural signals between the right and left cerebral hemispheres of the brain.t includes both the ventral and dorsal areas of the cingulate cortex, and appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate, as well as rational cognitive functions, such as reward anticipation, decision-making, empathy and emotion.

Ascending Tracts of the Spinal Cord Group of Neurons Forming Tracts. In terms of basic anatomy, the overall ascending pathway is made up of three different types of neurons. Firstly, there are first order neurons which receive sensory information from the receptors and send them to sensory neurons present in the posterior gray horns of spinal cord. The cell body of these neurons are found within the posterior nerve root ganglion. Next, there are second order neurons.

Place The Labels In Order Denoting The Flow Of Blood Through The Systemic Circuit Beginning With The Left Atrioventricular Valve And Ending In The Right Atrium. The First And Last Structures Are Given. It begins after the aortic valve where blood has left the heart, and ends in the superior and inferior vena cavae that bring deoxygenated blood from the organs back to the heart. Summary: The heart pumps blood through the coronary circulation to supply oxygen to the heart itself, and through the systemic circulation to supply the entire body other than the heart. Deoxygenated blood from all parts of the body enters into the heart through the superior and inferior vena cava. The blood enters the right atrium. When the right atrium contracts the blood is pushed into the right ventricle through the tricuspid valve.

- At the superior border of the pons, the basilar artery divides to form the two posterior cerebral arteries. Before the basilar artery divides, several other arteries arise from it. These include the anterior, inferior, and posterior cerebellar arteries as well as pontine branches.ne exception to this pattern is alternating hemiplegia. This is a paralysis that can be caused by ischemic stroke and affects different structures on each side of the body. It results from a brain stem lesion that damages cranial nerve nuclei and one side of the pyramidal tract in the same area.

How does blood get to the brain? Blood delivers fuel and nourishment to the brain through a complex system of blood vessels that reaches every neighborhood of the brain. The carotid arteries, which run up the left and right sides of the neck, are especially important, supplying blood to the front of the brain and the cerebral cortex.

- 25. The aortic arches connect the ventral blood vessel, a tube lying under the digestive tract, with the dorsal blood vessel, a tube lying on top of the digestive tract. The dorsal blood vessel is the main pumping organ for the blood and it carries blood in an anterior direction.The ventral blood vessel carries blood to the rear of the worm. Lateral blood vessels branch off from the two main vessels and carry blood to and from the internal organs.n animals, examples of organs are the brain, liver, heart, kidney, stomach, etc. Each organ has one or more particular functions to perform and the tissues in a particular organ work with each other to perform these functions. For example the human heart has the function of pumping blood throughout the body.
