What three substances diffuse into the cells from the capillaries?
The three main substances that diffuse into cells from capillaries are oxygen, carbon dioxide, and nutrients like glucose. Oxygen is essential for cellular respiration, carbon dioxide is a waste product that needs to be removed, and glucose provides energy for cellular processes.
What was the taste of each of the filtrate?
The filtrate that passed through the sugar cube was sweet, as the sugar dissolved in the water. The filtrate that passed through the activated charcoal tasted more neutral, as the charcoal absorbed impurities and removed flavor compounds from the water.
What happens to nutrients that are removed from the blood in the kidneys?
In the kidneys, nutrients removed from the blood during the filtration process are primarily reabsorbed back into the bloodstream. This reabsorption occurs in the renal tubules, where essential substances like glucose, amino acids, and certain ions are actively transported back to maintain homeostasis. Any excess nutrients that are not reabsorbed may be excreted in the urine. Thus, the kidneys play a crucial role in regulating nutrient balance in the body.
Why are useful molecules like glucose and other nutrients found in the filtrate along with urea and other wastes?
because glucose and other nutrients are small to filtrate through the filtration membrane and glucose is essential to be in the filtration membrane.
What are the four steps the human body uses to eliminate liquid waste?
The human body eliminates liquid waste through four main steps: filtration, reabsorption, secretion, and excretion. First, blood is filtered in the kidneys, where waste and excess substances are removed. Next, essential substances are reabsorbed back into the bloodstream. Finally, the remaining waste is secreted into the urine, which is excreted from the body through the urinary tract.
The filtrate removed from the blood by the kidneys might contain?
The kidneys remove toxic substances from the blood. The main substance that the kidneys filtrate from the blood is known as urea.
How are waste substances in the blood such as urea removed from the body?
The kidneys are the excretory and regulatory organs in the body. The kidneys contain over a million nephrons which are the functional units of the kidneys. Each nephron contains a renal corpuscle and a renal tubule. The renal corpuscle consists of capillaries called the glomerulus, enclosed by a capsule called Bowman's capsule. The blood is filtered in the glomerulus and the filtrate travels through the renal tubules were materials needed by the body is reabsorbed while the wastes are collected and excreted in the urine.Kidneys
What substances come out of the blood in the exchange at capillaries?
Oxygen and nutrients are delivered from the blood to tissues, and waste products such as carbon dioxide and metabolic byproducts are removed from tissues and transferred into the blood in the exchange at capillaries.
What materials remain in the blood after the filtrate has been removed?

What organisms have capillaries?
To the best of my knowledge, all organs have capillaries as this is how the tissue is fed nutrients and wastes are removed.
What organs have no capillaries?
To the best of my knowledge, all organs have capillaries as this is how the tissue is fed nutrients and wastes are removed.

What is removed at the proximal convoluted tubule?
At the proximal convoluted tubule, reabsorption of water, glucose, amino acids, and ions (such as sodium, potassium, and chloride) from the filtrate back into the bloodstream occurs. Waste products and toxins are also secreted into the tubule for excretion in the urine.
Why are useful molecules like glucose and other nutrients found in the filtrate along with urea and other wastes?
because glucose and other nutrients are small to filtrate through the filtration membrane and glucose is essential to be in the filtration membrane.
What is the call membrane?
Nephrons are the basic functional unit of the kidneys. They take in blood through an afferent arteriole and filter it inside the Bowman's capsule in a series of capillaries called glomeruli. It is the walls of the glomeruli that contain the membrane, more accurately called semi-permeable membrane, that removed the serum from the blood to produce the filtrate that will eventually become urine.
