The kidneys are served by the renal artery and vein. The renal artery enters the kidney just medial to the hilum of the kidney and supplies it with oxygenated blood. The renal vein exits the kidney just lateral to the hilum and carries deoxygenated blood away from the kidney.
In addition, the kidneys are further served by the gonadal artery, which is the primary blood supply to the ureters and bladder. The gonadal vein serves to carry deoxygenated blood away from the ureters and bladder.

Which of the given arteries supplies blood to the kidneys?
The renal arteries are the arteries that supply blood to the kidneys. They are paired branches of the abdominal aorta. Each artery passes between the vertebrae of the backbone and enters the kidney at the hilus, the indentation in the middle of the organ, where it divides into many small branches and penetrates the kidney tissue.
The right renal artery passes slightly more superiorly behind the inferior vena cava, while the left renal artery passes slightly inferiorly and laterally. Each of the two renal arteries divides into five segments, with each segment supplying a different region of the kidney.
These segments help collateralize the renal circulation to keep the kidney adequately perfused.
What organs are served by the renal arteries and veins quizlet?
The renal arteries and veins bring blood to and away from the kidneys. The kidneys are organs in the urinary system, located toward the back of the abdominal cavity and just above the waist. The renal arteries carry oxygen-rich blood from the aorta of the heart to the kidneys, where it is filtered and passed through the tubules to produce urine.
The renal veins then carry the deoxygenated blood from the kidneys back to the heart to be reoxygenated. The renal arteries and veins supply blood to all the different parts of the kidneys, including the cortex, medulla, pelvis, and ureters.
Which blood vessels supply the kidneys with blood quizlet?
The kidneys are supplied with blood by two major vessels: the renal artery and the renal vein. The renal artery carries oxygen-rich blood from the aorta, which is the main artery in the body, to the kidneys.
This artery branches off into smaller vessels, known as interlobar arteries, which further branch into the arcuate arteries and then into the interlobular arteries to reach the kidneys. The renal vein carries oxygen-poor blood from the kidneys back to the inferior vena cava, which is the body’s main vein.
The renal artery and renal vein are connected to the surrounding organs via the renal capillaries, which allow for the exchange of nutrients and waste products between the kidneys and the bloodstream.
What is the work of renal vein?
The renal vein is a blood vessel that carries oxygen-rich (oxygenated) blood away from the kidneys. Located in the abdominal cavity, these veins are connected to the left and right renal arteries. The renal vein brings blood from the kidneys to the inferior vena cava, where it is transported to the heart.
Along the way, the blood is filtered to remove waste and toxins from the body. This process is essential for eliminating metabolic waste, excess hormones, and salt from the body. Additionally, the renal vein helps to regulate blood pressure and the balance of electrolytes and fluids in the body.
When toxins are not sufficiently filtered from the blood, the kidneys may become damaged and lead to medical complications such as kidney failure. Therefore, the renal vein plays an important role in maintaining the health and well-being of the body.
What is the function of the renal artery quizlet?
The renal artery is responsible for supplying the kidneys with oxygenated blood that has been filtered from the aorta. It also carries away any waste products and excess fluid that the kidneys need to excrete from the body.
This essential vascular structure runs from the abdominal aorta directly to the kidneys, allowing for direct communication between the two organs. The renal artery is also responsible for regulating blood pressure by ensuring that the proper amount of pressure is being maintained throughout the body.
It is the role of the renal artery to transport hormones, nutrients and other substances to the kidneys for proper metabolic breakdown, as well as carrying away waste products for elimination. By playing its part in integral bodily functions, the renal artery plays an essential role in keeping the body functioning optimally.
Which is the correct order of blood flow through the kidneys?
The correct order of blood flow through the kidneys is: renal artery → afferent arterioles → glomerulus → efferent arteriole → peritubular capillaries → interlobular veins → renal vein.
The renal artery is the main artery supplying the kidneys with oxygenated blood from the heart. The renal artery branches out into afferent arterioles, which supply blood to the glomerulus in each nephron.
The glomerulus is a structural unit of a kidney that filters the blood and creates urine. The blood then passes from the glomerulus, into the efferent arterioles which serve to regulate the pressure in the glomerular capillaries.
From the efferent arterioles, the blood then moves into the peritubular capillaries which collect the filtrate from the nephrons. This filtrate then flows along interlobular veins, where it is transported through the interlobular spaces back to the renal vein.
The renal vein then carries the filtered substances back to the heart and lungs, completing the cycle.
What is the blood supply to the urinary system?
The urinary system is supplied with oxygenated blood mainly from the aorta via the renal arteries. The renal arteries then branches off into smaller arteries, which will eventually reach the renal cortex and medulla, resulting in capillaries that form the glomerular network.
This network of capillaries is responsible for the formation of urine from the glomerular filtration of blood. Circulating blood then enters the peritubular capillaries, which transport fluid and electrolytes within the renal tubules.
The renal veins finally take the deoxygenated blood away from the kidneys, aiding in the drainage of the kidney capsule and liver, and carrying it back to the inferior vena cava and then to the right atrium of the heart.
What are the 4 blood vessels directly associated with the nephron?
The nephron is the basic unit of the kidney and is responsible for filtering blood and forming urine. The four blood vessels directly associated with its functioning are the renal artery, renal vein, afferent arteriole, and efferent arteriole.
The renal artery brings oxygenated blood from the aorta to the kidney and supplies the nephron with nutrients. The renal vein is responsible for carrying the filtered blood away from the kidney. The afferent and efferent arterioles help control the flow of blood through the nephron.
The afferent arteriole is responsible for bringing filtered blood into the nephron, while the efferent arteriole carries it out. Together, these four blood vessels ensure that the nephron is able to effectively filter blood and produce urine.
What are the 5 functions of the kidneys?
The kidneys are one of the most important organs in the human body and they have five primary functions:
1. Regulation of water and ion balance. The kidneys work to regulate the hydration of the body by regulating the electrolyte balance of calcium, potassium, sodium, chloride, and magnesium. This helps maintain the overall fluid balance in the body.
2. Activation of vitamin D. Another important role the kidneys play is in the production of activated vitamin D, which helps the body absorb calcium and phosphorus for strong bones.
3. Removal of metabolic waste products. The kidneys help to filter out toxins that accumulate in the blood from metabolic processes, such as urea and creatinine, by removing them from the bloodstream and circulating them back through the urinary system for excretion.
4. Production of hormones. The kidneys also produce different hormones that regulate blood pressure, red blood cell production, and bone formation.
5. Maintenance of acid-base balance. The kidneys are responsible for maintaining the pH balance of the blood, by excreting acidic waste through urine and by regulating the electrolytes that make up the body’s internal environment.
