The Bowmans's capsule is found in the region of the kidney called the:
pelvis
pyramid
cortex
medulla
The best description of digestion is the:
action of enzymes on food in the digestive tract
breakdown of complex organic molecules into small molecules that can be used by the body
dissolving of food and its absorption into the blood
breaking up of food into soluble molecules that can diffuse through the cell membranes
Three of the following aid in the transfer of certain substances from the bloodstream to the tubules of the mammalian kidney. Which one does not?
the considerable surface area of the capillaries comprising the glomerulus
the relatively small sizes of the molecules (or ions) of these substances
the larger diameter of the arteriole leaving Bowman's capsule compared with the diameter of the arteriole entering the capsule
the relatively great length of each of the tubules
The stomach is a hollow, muscular organ between the oesophagus and (a) .
In the stomach, food is mixed in an acidic environment to produce a semi-fluid mixture called (a) .
The (a) pH of the stomach denatures enzymes, destroys microbes, and activates a protein-digesting enzyme precursor.
In the (a) , one of three sections of the small intestine, chemical digestion occurs.
The intestinal lining is folded into many intestinal (a) which increase surface area for nutrient adsorption.
The intestinal villus are made of (a) cells. These villus have a brush border of many microvilli, which are primarily responsible for nutrient absorption.
(a) are bound to the microvilli of the epithelial cells, and are present in the pancreatic and intestinal juices. They break down fats, peptides and carbohydrates. These small products molecules of this process are absorbed into the underlying lymph and blood vessels.
Tubular exocrine glands and globlet cells secreet an (a) fluid and mucus into the lumen, neutralizing the acidity of the chyme entering the small intestine from the stomach and protecting the lining of the intestine from damage.
Amylase is:
An enzyme released from the microvilli in the small intestine which breaks down starch into smaller maltose molecules.
An enzyme which breaks down the common organic molecule, amylate, which is found in food.
An enzyme produced by the salivary gland and pancreas that breaks down starch into smaller matlose molecules.
An enzyme released from the salivary glands and pancreas that breaks down proteins into smaller peptide untis.
Urea is:
produced by the mammalian liver and excreted as an insulble white liquid.
the primary nitrogenous excretory product of mammals.
excreted directly into the water where it is diluted
the common compound (CO(NH2)2) derived from the break down of nitrogen containing compounds such as carbohydrates and lipids.
The kidney is:
a bean shaped excretory organ in vertebrates, which removes and concentrates metabolic wastes from the blood and moves them to bladder via the ureter.
Part of the gut which recieves chyme directly from the stomach. Here, digestive enzymes are added, which break down food and tood molecules are reabsorbed into the blood.
located in the upper part of the ribcage to enable easier access to the dorsal aorta and vena carva.
An excretory organ comprised of millions of functional filtration units called filtration cells.
The length of this structure, know as the (a) , is directly related to the ability of an organism to concentrate urine.
The nephron is the function selective filter element of the kidney. It is comprised of the:
Renal corpuscle
Distal and proximal concoluted tubule
Loop of Henle
Ureter
Collecting duct
Overall, how confident are you with the content from this week?
Not confident.
Neutral, needs work.
Satisfied, I'll revise later.
Confiedent and ready to move on.
