Answer:
a. in the bottom of the atrium just above the ventricles
Explanation:
AV node -
It helps to control the heart rate , it serves as an electrical relay station , reduces the electrical current which is sent by the SA node .
The location of the AV node , is at the lower back section of the inter atrial septum , and conducts the electrical impulse normally from the atria to ventricles .
Answer:
Removal of the pancreas would have the most severe effects on absorption because most chemical digestion occurs in the small intestine. Absorption requires the action of pancreatic enzymes, making the pancreas the most important.
Hope this helps! :))
Explanation:
Confirmatory Tests vary, and may be wrong from time to time. As time passes, the test is not as reliable as stated. If the so called "blood" is on a leather surface, blood isn't too prone to sticking to leather, so it may (or may not) be blood.
Answer:
Explanation:
The osmotic gradient in the kidney typically in the medulla is a process that generates urine that is 5 times more concentrated so as to reduce the loss of water from the body.
The countercurrent multiplication is a process that uses energy to produce the osmotic gradient in the kidney, this process facilitates the reabsorption of water from the tubular fluid. This mechanism moves the sodium chloride from the tubular fluid to the interstitial space of the kidneys. The osmotic gradient can be developed in two ways:
1. The single effect: This involves the transport of sodium chloride from the tubular fluid and moved to the ascending limb then finally to the interstitial fluid. As a result of this, the water moves passively down to the concentration gradient out of the tubular fluid than to the descending limb of the interstitial space, until the equilibrium is achieved.
2. Fluid flow method: The tubular fluid enters into the descending limb. This pushes the fluid into high osmolarity typically down the tube. This way the osmotic gradient develops.
Answer:
Peristalsis is defined as the involuntary movement which involves contraction and relaxation of muscles present in the digestive tract originates from the esophagus.
In diarrheal condition the Peristalsis movement does not take place properly as it is not a voluntary muscle movement so it can not be controlled consciously. it is important to digestion but, in case of diarrhea or constipation something goes haywire with peristalsis . this condition can also be defined as motility (hypermotility) disorder.
