Answer:
Blood enter the right atrium of the heart via the vena cava (superior and inferior)
The right atrium contracts to push the blood into the right ventricle through the triscupid valve
The contraction of the right ventricle pushes the blood through the pulmonary valve to the pulmonary artery which carries it to the lungs to be oxygenated
After oxygenation, the pulmonary vein brings blood to the left atrium
Contraction of the left atrium pushes the blood through the mitral valve into the left ventricle
The left ventricle contracts to push the blood through the aortic valve, into the aorta, which carries the blood through the body.
Explanation:
Answer:
B. Antibodies react specifically with an antigen.
Explanation:
Serological tests are blood tests that look for antibodies in your blood. They can involve a number of laboratory techniques. Flucculation tests are based on the precipitation that takes place when antibody and specially prepared antigens are mixed together
The main parts of the brain involved in language processes are the Broca's area, located in the left frontal lobe, which is responsible for speech production and articulation, and the Wernicke's area, in the left temporal lobe, associated with language development and comprehension.
Answer:
The correct answer is - More motor neurons and larger motor units are activated to stimulate a greater number of muscle fibers for a more powerful muscle contraction.
Explanation:
Recruitment in muscle contraction or motor unit recruitment refers to the periodical stimulation or activation of the one or more motor neurons to get the more or enhanced strength in a muscle contraction.
Additional motor neurons or motor units are activated, along with larger motor units to stimulates a higher number of fibers for increased strength of muscle contraction.
