Osmosis of Water Across the Membrane. Osmosis is the tendency for water molecules to move from where there is a higher concentration to where there is a lower one. ... The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis
The cramps can be caused due to anaerobic respiration in the muscles and lactic acid formation.
During intense physical activity the muscles become deprived of oxygen, in this condition, anaerobic respiration takes place in the muscle cells causes the formation of the lactic acid.
The physical training increases the strength of the muscles, which can help the muscles not to get tired easily. that is why, physical training is required before any marathon.
I think it is D. You experience increase in breathing rate to obtain more oxygen which is delivered to cells through the bloodstream
Answer:
Most nerve fibers from both divisions innervate many of the same effectors.
Most nerve fibers from both divisions share the same sites of origin.
The parasympathetic nervous system is responsible for controlling the homeostasis, resting and digestion functions of the body. The sympathetic nervous system controls the body's response against threat and fight and flight responses. Both parasympathetic and sympathetic nervous systems are responsible for the involuntary functions of the human body.
Most nerve fibers from both divisions share the same sites of origin because both have the nerve fibers that are originated from brain or spinal cord that are directed or passes to the targeted organs.
Most nerve fibers from both divisions innervate many of the same effectors so as to induce functions according to the bodily needs.
