Answer:
1. Muscle fiber: causes the actual contraction of muscle to raise legs
2.Erythrocyte: keeps tissue involve alive, provides oxygen for energy for motion
3. Neuron: sends message from brain to move up
4. Leukocyte: keeps the tissue involved free of disease.
Explanation:
1. Muscle fiber: causes the actual contraction of muscle to raise legs.
The muscular fiber is a long elliptic cell, able to contract, extend, stretch and respond to electrical changes in the membrane.
2. Erythrocyte: keeps tissue involve alive, provides oxygen for energy for motion
An Erythrocyte or red blood cell contain a protein called hemoglobin, which transport oxygen ions from the lungs towards the whole body.
3. Neuron: sends message from brain to move up.
A Neuron is a specialized cell from the nervous system that receives, processes and transmits information from the brain to other parts of the body.
4. Leukocyte: keeps the tissue involved free of disease.
A Leukocyte is a type of blood cell that belongs to the immune system. They fight infections and other diseases.
