They play an important role in the regulation of blood pressure as a part of the Tubuloglomerular feedback mechanism. The afferent arterioles branch from the renal artery , which supplies blood to the kidney s. The afferent arterioles later diverge into the Capillary capillaries of the glomerulus kidney glomerulus . When renal blood flow is reduced indicating hypotension or there is a decrease in Sodium and Chloride ion concentration the macula densa of the distal tubule releases prostaglandins , which cause the juxtaglomerular cells lining the afferent arterioles to release renin , activating the renin angiotensin aldosterone system , to increase blood pressure and increase retention of Sodium ions via aldosterone . The macula densa cell can also increase the local blood pressure of the Afferent Arterioles by increasing the synthesis of Nitrous Oxide or decreasing the synthesis of Adenosine or Adenosine triphosphate ATP . If the afferent arterioles are constricted then the blood pressure in the capillaries of the kidneys will drop.

Note how the tissue fluid is entering the blind ends of lymph capillaries indicated by deep green arrows Image2 Caption2 Precursor System Artery Vein Nerve Lymph MeshName MeshNumber Lymph capillaries or lymphatic capillaries are tiny thin walled vessels that are closed at one end and are located in the spaces between cells throughout the body, except in the central nervous system , and in non vascular tissues. The main purpose of these vessels is to drain excess tissue fluids from around the cell ready to be filtered and returned to the venous circulation. This tissue fluid upon entering the lumen anatomy lumen elongated cavity of a tubular structure is known as the lymph . Lymphatic capillaries are slightly larger in diameter than blood capillaries and have a unique structure that permits interstitial fluid to flow into them but not out. The ends of endothelial cells that make up the wall of a lymphatic capillary overlap. When pressure is greater in the interstitial fluid than in lymph, the cells separate slightly, like the opening of a one way swinging door, and interstitial fluid enters the lymphatic capillary.

Infobox Nerve Name Afferent nerve fiber Latin neurofibrae afferentes GraySubject GrayPage Image Caption Image2 Caption2 Precursor System Artery Vein Nerve Lymph MeshName MeshNumber In the nervous system , afferent neurons otherwise known as sensory neuron sensory or receptor neuron s , carry action potential nerve impulses from receptor biochemistry receptor s or sense organs towards the central nervous system . This term can also be used to describe relative connections between structures. Afferent neurons communicate with specialized interneuron s. The opposite activity of direction or flow is efferent nerve fiber efferent . In the nervous system there is a closed loop system of sensation, decision, and reactions. This process is carried out through the activity of afferent neurons, interneurons, and efferent neurons. A touch or pain ful stimulus physiology stimulus , for example, creates a sensation in the brain only after information about the stimulus travels there via afferent nerve pathways. Afferent neurons are pseudounipolar neurons , that have a single long dendrite and a short axon Citation needed date September 2010 , and a smooth and rounded cell soma biology body . The dendrite is structurally and functionally similar to an axon, and is myelin ated it is these axon like dendrites that make up the afferent nerves.

Orphan date February 2009 Unreferenced date September 2007 Lymph Hearts are organs found in lungfishes , all amphibians , reptiles and flightless birds . They function as small pumps that pump lymph fluid, proteins and ions that has leaked out of the circulatory system , back into the circulatory system. These hearts vary in size from microscopic in lungfish to an estimated 20 liters capacity in some of the largest dinosaur s. In frogs and turtles they pump at rates higher than the blood heart and the volumes pumped are quite remarkable. In toads and frogs this volume can amount to about 1 50th of the output of the blood heart. In amphibians, lymph hearts lie at vein junctions. Frogs and salamanders have 10 to 20 lymph hearts, while caecilians have more than 100. Conversely, reptiles have single pair of lymph hearts in the pelvic area. In flightless ratite birds the lymph heart function is less clear and the two almond sized hearts located near the spinal column close to the hip joint are thought to be involved in inflating and deflating the phallus with lymph which is of a significant size in both sexes of emus and ostriches .
