Space, the final frontier! Indeed, but being in space causes some problems. Astronauts in space show a decline in their ability to mount an immune response and, consequently, develop a decreased resistance to infection. Two potentially important differences in physiology in space versus on Earth are more fluid flowing to the head and a lack of weight bearing on the lower limbs. Could they be involved somehow in the deleterious effect on the immune system? Design an experiment to be done on Earth to answer this question.

To review:

Based on the fact that astronauts in space show a decline in their ability to mount an immune response and, consequently, develop a decreased resistance to infection. An experiment to be designed on Earth to answer this question.

Introduction:

Zero or micro gravity is exhibited in space as well as by the absence of air and atmosphere. Since space does not contain air in space and no atmosphere, so there is no gravity. Microgravity can only be experienced on research center designed in NASA. Human body when experience microgravity affect many body system functions, since humans evolved on Earth and are acclimatized to earth gravitational field.

As reported from studies astronauts living in space for prolonged time experience trouble in their blood circulation and eyesight. An experiment can be conducted with the group of 10 astronauts on research center designed in NASA to experience microgravity. These astronauts will be kept in microgravity for short duration 30 days, mid duration 120 days, and prolonged duration 360 days. After experiment, fluid samples were collected and undergo rigorous medical testing.

Results revealed that astronauts experience losses in bone and muscle tissue. Person living for prolonged duration experience higher bone and muscle tissue loss.

Prolonged duration astronauts experience higher dizziness caused by poor circulation or a disturbed sense of balance.

In space, with no gravity blood and other fluid circulate is highly affected, which pull fluids like blood down the legs, and fluids shift toward the upper body—the head...
