What are the gross structures of the kidney?
Internal Gross Anatomy The pyramids and renal columns taken together constitute the kidney lobes. The cortex and medulla contain many nephrons – the microscopic filtering units of the kidney responsible for producing urine.
What structures lie behind the kidney?
They are considered retroperitoneal, which means that they lie behind the peritoneum. The renal artery connects the kidneys to the aorta, while the renal vein connects the kidneys to the inferior vena cava. The adrenal glands lie superior to the kidneys.
What is the gross anatomy of the kidney and its coverings?
Describe the gross anatomy of the kidney and its coverings. The kidneys are bean-shaped organs that lie retroperitoneal in the superior lumbar region. The medial side is concave and has a renal hilus that leads into a renal sinus, where the blood vessels, nerves and lymphatics lie.
What are the 7 functions of the kidney?

What is the structure and function of kidneys?
The kidneys filter the blood to remove waste products, which they convert into urine. Urine is carried from each kidney, through a tube called a ureter to the bladder, where it is stored. The ureter and blood vessels enter and exit the kidney through the renal hilum.
Which kidney is higher in the body?
Every healthy human body has two kidneys, the left and the right. Each kidney is about four or five inches long, shaped somewhat like a bean. The left kidney sits a bit higher in the body because of the size of the liver, which is also on the right side.

Where are the renal columns located in the kidney?
A frontal section through the kidney (Figure 2) reveals an outer region called the renal cortex and an inner region called the renal medulla. The renal columns are connective tissue extensions that radiate downward from the cortex through the medulla to separate the most characteristic features of the medulla, the renal pyramids.
How big is the upper part of the kidney?
