Transcript of THE KIDNEY

What is the role of the Kidney?
The kidney's role is to regulate the amount of salts, acids, alkaline, and fluids in the blood. That results to the regulation of the blood pressure of the body. It also produces hormones that help regulate the blood temperature. It also gets rid of wastes in the body. Simply, the kidneys are the body's natural filter.
The nephron is the basic functional unit of the kidney. A nephron is made of capillaries and tubules. A single kidney is made up of more than a million nephrons!
The kidney is made up of the cortex, medulla, renal pelvis, ureter, renal arteries, and renal veins.
The aorta supplies the kidneys with its blood supply. The blood travels from the aorta into the renal artery. Then the renal artery branches off in the renal pyramids (medulla) until it becomes capillaries in each nephron. Blood is filtered in each nephron. After the process of filtration, reabsorption, and secretion, the urine travels into the collecting ducts to the renal pelvis to the ureter.The filtered blood gets out of the kidney through renal veins to the the inferior vena cava.
Renal Pelvis
Renal Artery
Renal Veins
- The Ureter: After filtering the blood, the wastes (urine) is sent to the bladder through the ureter.
- The Abdominal Aorta: supplies the kidneys with blood
- Renal Veins: Renal veins are veins that are connected to the kidney to carry back filtered blood to the Inferior Vena Cava which carries the blood to the rest of the body.

Some Interactions
The kidneys are "transplantable" unlike other organs.Before the transplantation, the surgeon should make sure that both the donor and the patient have the same ABO blood type and that they have matching tissues. The kidneys cannot be transplanted by themselves, the kidneys and the ureters are both transplanted.After the transplantation the patient has to take Immunosuppressant drugs to stop the body's immune system from rejecting the new kidney for the rest of their lives.
Glomerulonephritis is a name that is given to diseases that affect the glomeruli. Xanthine Oxidase Deficiency is a genitic disorder which results to high amounts of xanthine in the urine and blood. Diabetes mellitus also highly affects the kidney function. Hypertension also affects the kidneys. All listed diseases or conditions may lead to renal failure which will then require the patient start dialysis. Dialysis is a process where machines remove extra water and harmful elements from the blood from patients with renal failure or a lost kidney.

Step 1: Use the clay to make the shape of the kidney.
Step2: Paint the whole kidney in one color and wait for it to dry.
Step 3: Paint the parts of the kidney in different colors and wait for them to dry.
