Name the main nitrogenous waste in human blood How is it removed from the blood?
The main nitrogenous waste in human blood is urea, which is produced from the breakdown of proteins and amino acids. Urea is primarily removed from the blood by the kidneys through a process called filtration in the nephrons, where it is excreted in urine. The kidneys filter the blood, reabsorbing necessary substances and allowing urea to be eliminated from the body, thereby maintaining nitrogen balance.
What is plasma called after proteins are removed?
After proteins are removed from plasma, the remaining fluid is called serum. Serum contains electrolytes, hormones, nutrients, and waste products but lacks clotting factors, which are primarily proteins. This makes serum distinct from plasma, which includes these clotting proteins.
What liquid always flows through the kidneys being filtered by a million tiny units called nephrons?
The liquid that always flows through the kidneys and is filtered by nephrons is blood. The kidneys receive blood through the renal arteries, which then passes through the nephrons, where waste products and excess substances are removed to form urine. This filtration process is essential for maintaining the body's fluid and electrolyte balance.
3 How do cortical nephrons and juxtamedullary nephrons differ structurally?
The cortical nephrons,from their name are almost entirely embedded within the cortex of the kidney.They have shortish loops of Henle that do not really extend far into the medulla. By contrast, the juxtamedullary nephrons have longs loops of Henle that do extend far into the medulla.The glomeruli of the juxtamedullary nephrons are typically close to the medulla (which is how these got their name)
What are the filters inside a kidney called?
The filters inside a kidney are called nephrons. Each kidney contains thousands of nephrons, which are responsible for filtering waste and excess substances from the blood to form urine.
What substance is removed from the bloodstream by nephrons in the kidneys?
urea
Which filtrates is not reabsorbed in signiticant quantities in the bloodstream by the nephrons?
Large proteins such as albumin are not reabsorbed in significant quantities in the bloodstream by the nephrons in the kidneys. These proteins remain in the glomerular filtrate and are eventually excreted in the urine.
What is a tiny filtering unit in the kidney?
The filtering unit of the kidney is the nephrons.

How many nephrons in each kidney?
There are about 1 million nephrons in a kidney. Most humans have 2 kidneys.

The liquid that always flows through the kidneys and is filtered by nephrons is blood. The kidneys receive blood through the renal arteries, which then passes through the nephrons, where waste products and excess substances are removed to form urine. This filtration process is essential for maintaining the body's fluid and electrolyte balance.
Does the cortex contain nephrons?
No, the cortex does not contain nephrons. Nephrons are the functional units of the kidneys and are predominantly located in the renal cortex and renal medulla.
When the proteins are removed from plasma the remaining fluid is called what?
serum
The process by which amino groups are removed from proteins is called?
Deamination
What are nephrons called if they are located mainly in the cortex?
Cortical nephrons are located mainly in the cortex of the kidney. They have shorter loops of Henle that mainly dip into the outer medulla. These nephrons are responsible for most of the kidney's filtration processes.
Where are the majority of nephrons located?
The majority of nephrons are located in the outer region of the cortex.
