What else can I help you with?
The client was admitted to the hospital for dehydration Explain what changes occur in extracellular and intracellular fluid compartments during dehydration?
Fluid is lost from the intracellular compartment due to sweating which is replaced by fluid from the interstitial compartment by osmosis which then pulls fluid from the intravascular compartment by osmosis.
Explain which is faster digestion during sleep and physical exercise?
You will digest more efficiently during sleep as your parasympathetic nervous system is dominant at rest which favours blood flow through your enteric bloodstream which enhances absorption of gut breakdown products. Parasympathetic activation also stimulates salivary gland secretion, gastric activity and peristalsis.During exercise, the sympathetic nervous system is predominantly active and the release of catecholamines stimulate peripheral vasoconstriction to the renal and mesenteric circulation effectively reducing blood flow to those systems whilst enhancing blood flow through the coronary and skeletal muscles system in the fight and flight response.
Explain why most food nutrients do need to be digested?
Most food nutrients are in large, complex molecules that are not directly absorbable by the body in their current form. Digestion breaks down these complex molecules into simpler, more easily absorbed forms that can be utilized by the body for energy, growth, and repair.
He thoracic cavity is surrounded by a stiff rib cage while the abdominal cavity has softer muscular wall Explain how such structures are beneficial in each case?
The stiff rib cage surrounding the thoracic cavity provides protection for vital organs such as the heart and lungs, helping to prevent injuries to these structures. In contrast, the softer muscular wall surrounding the abdominal cavity allows for more flexibility and movement, which is necessary for functions such as digestion and childbirth.
What did Darwin use to explain evultion?
Darwin used the theory of natural selection to explain evolution. Natural selection is the process by which organisms best adapted to their environment tend to survive and pass on their genetic traits to offspring. This concept helps to explain how species gradually change over time, leading to the diversity of life we see today.

Explain why the stomach produces hydrochloric acid?

Explain the process of digestion if a student puts a plain cracker in their mouth, chews it, and holds the mush in their mouth.?
because of the digestive system
How does the model need to be modified to explain the digestion of proteins and starch?
I hatsciwnce science is crap its all enzymes and biological acissors whicj i dont get
Explain why chemical digestion does not begin in the mouth for all foods?
Chemical digestion in the mouth primarily involves the breakdown of carbohydrates by the enzyme amylase in saliva. Not all foods require significant carbohydrate digestion, such as proteins and fats. Therefore, chemical digestion for these macronutrients begins further down the digestive tract, where specific enzymes like pepsin and lipase are present.
Explain the importance of cellulose in the human diet?
Humans lack the necessary enzyme to digest cellulose, so it acts as roughage in the intestines and helps with the digestion process
The client was admitted to the hospital for dehydration Explain what changes occur in extracellular and intracellular fluid compartments during dehydration?
Fluid is lost from the intracellular compartment due to sweating which is replaced by fluid from the interstitial compartment by osmosis which then pulls fluid from the intravascular compartment by osmosis.
Do all mammals birds reptiles amphibians and fish have the same organ systems as humans Explain?
no many have extra organs to do other things like a cow has 4stomachs to help digestion
Explain of one strong and weak acid and give their uses?
strong acid- hydrochloric acid - used for digestion as a secretion of stomach weak acid- citric acid - used for maintaining salts in body
Explain why digestion of starch to glucose is necessary?
Starch is a large macromolecule, so needs to be broken down into simple sugars which can be absorbed into the blood stream
