What is the knot of coiled capillaries found in the kidneys and forms the filtrate?

This is a tuft of capillaries called the glomerulus. The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.

What is formed with coiled up DNA?
Coiled up DNA, combined with protein histone, forms chromosomes.
What forms the glomerulus?
Capillaries.
Is the glomerulus thought of as the filter of the kidney since it forms a fluid called filtrate or ultrafiltrate from the blood?
true
What tissue forms a wall of capillaries and air sacs of lungs?
Transitional arms
What basic protein forms the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes?
Histones and other associated proteins
What is Tightly coiled form of DNA called?
Coiled up DNA, combined with protein histone, forms chromosomes.
Describe how your kidneys remove waste from your body?
The kidney receives blood that it must filter. It has filtering chambers. It separates bad things and converts it to urea. Then it goes through small tubing after it is filtered. The good cleaned blood is sent back to the body and the urea is sent to the bladder.
What is produced when the kidneys mix waste with water?
When your kineys mix waste with water it forms urine.
When you filter something what is the stuff inside the filter called?
Filtrate goes through the filter while the material trapped by the filter forms a cake...hence the name: Filter Cake.
How do the kidneys help to prevent blood pH from rising?
If blood pH is too low (ph < 7.35 ) = acidosis If blood pH is too high (pH > 7.45) = alkalosis In alkalosis: at the intercalated cells of the collecting duct the following occurs: secretion of Hco3- (via Hco3- / cl- antiporters) into the glomerular filtrate, which ultimately forms the urine. Rebsorption of Hydrogen ions (via ATPase dependant proton pumps)
Many medications introduced into the bloodstream cannot directly affect the neurons of the CNS because?
the endothelium of CNS capillaries forms a blood-brain barrier
Why is portal renal and coronary circulation classified as special circuits?
Coronary circulation allows us to pay attention to the needs of the heart tissue. The heart pumps and circulates blood around the body non-stop your whole life but this is its function. To get oxygen and nutrients, arterial branches from the aorta called coronary arteries must enter both sides of the heart, infiltrate it as it branches off many more times to reach the cardiac cells that compose the heart. The tiniest branches called arterioles must form microscopic vessels called capillaries that can pass close to cells. Here oxygen and nutrients diffuse into the cells and waste materials such as carbon dioxide and nitrogenous wastes diffuse out of cells into the capillaries. As the blood from the capillaries moves past the cells, small veins called venules move blood away from the heart tissue and converge towards the superior vena cava via coronary veins and enter the right side of the heart. Renal Circulation is noteworthy because as the renal arteries branch from the aorta to deliver oxygen and nutrients to the kidneys, a filtering service is supplied by the kidney filtering units known as nephrons. Excess water, excess salt and urea, a toxic nitrogenous waste is removed from the blood as it passes through the kidneys. This is filtrate that forms urine which gets directed to the urinary bladder for excretion. The renal veins that leave the kidneys carry deoxygenated but more purified blood compared to the renal arteries that bring oxygenated but less purified blood.
