Exercise is very vital to the body,it a form of physical activity.the sole aim of excercise is to maintain stamina, flexibility,keep fit and be overly healthy and well.
When we excercise, our heart rate increases and then it returns to the normal rate when with rest,when we take a break.there is reflection of vasoconstriction in the fingers as the blood is shunted to only the exercising muscles because it is noted that the pulse amplitude of the heart is always small after excercise and and increases slowly during recovery.
The amount of blood the heart pumps in a minute,that is the amount of blood ejected by the contraction of the left ventricle into systemic circulation increases when we are exercising and resistance to blood flow by skeletal muscles decreases.the blood vessels will try to adapt to the condition (exercise) inorder to control blood flow and as well meet energy demands.
When we finish exercising,our body temperature increases which will inturn cause increase in the pulse rate and the blood in our body makes way to our skin,hands and legs inorder to clear off the energy that was generated by the body(muscles) during exercise
Answer:
Molecules that are not soluble in water are fats and non-polar molecules . During their digestion and absorption in the small snall intestine, fats are packaged into hydrophilic form.
Explanation:
This explains the digestion of fats in the small intestine. This takes place in the illeum.( the longest part of 3.5 m) Bile salts from the liver, emulsified these fats, covering then with layers,while enzymatic action by lipase, from the pancreases, completes the process.
These fatty substance formed are called Micelles.In the intestinal cells, the micelles are covered by protein and lipids to aid transport in water medium of the intestine.A this sage they are called (lipoprotein).
They are absorbed in the lacteal- the lymphatic capillaries , unlike protein and CHO which are absorbed directly in the blood stream.I
They are finally absorbed into the blood stream via the lymphatic vessels.
