What else can I help you with?
What muscle contract during inhalation and what muscles contract during exhalation?
The intercostal muscles, (muscles between the ribs), contract.
What effect does microgravity have on muscles?
In the near-zero gravity of Earth orbit, muscles that are ordinarily used for standing, walking, or balancing are not needed. During prolonged periods in space, astronauts have to work these muscles to keep them from atrophying (reducing in size and strength).
What causes muscles of the uterus to contract during childbirth?
Oxitosin is the hormone. It is secreted by pituitary.
What is the problem met by astronout during space explanation?
One problem met by astronauts during space exploration is the effect low gravity has on the body. It can cause muscles to atrophy and lose core strength.
What happens to the muscles of astronauts who are in space for a extended period?
In space, astronauts experience muscle atrophy due to the microgravity environment, which reduces the mechanical load on their muscles. Without the need to support their body weight, muscles can weaken and shrink, leading to a decrease in strength and endurance. To combat this, astronauts engage in regular resistance and aerobic exercise while aboard the International Space Station to help maintain muscle mass and overall fitness. Despite these efforts, some muscle loss still occurs during extended missions.
What happens right after lifting weights?
Your muscles that were broken down during workout start repairing themselves using the energy and protein you provide in your diet. This is what causes our muscles to develop and grow.
Why do astronauts need to do special exercises?
Astronauts need to do special exercises in space to prevent muscle and bone loss due to the lack of gravity. Without the effects of gravity on their bodies, muscles and bones can weaken and deteriorate over time. Special exercises help maintain their physical health during space missions and upon return to Earth.
Where did the astronauts stay during launch and reentry in Apollo?
Astronauts stayed inside the Apollo Command Module during launch and reentry. This module was attached to the Saturn V rocket during launch and detached for reentry to bring the astronauts safely back to Earth.
How many astronauts wolked on the Apollo moon landing?
A total of 12 astronauts walked on the moon during the Apollo missions, from 1969 to 1972. Each Apollo mission had a team of astronauts, with two astronauts landing and walking on the moon's surface during each mission.
How many astrounot wakl in the moon during Apollo mission?
During the Apollo mission a total of 12 astronauts walked on the moon. On each trip to the moon 2 astronauts walked on the moon.
What molecule increases in the blood during exercise?
During exercise our blood circulation speed increases. It effect in amino acid and a molecule ATP which causes muscles to increase strength.
Did the shuttle columbia's astronauts survive?
no, all the astronauts on the final mission of columbia died during reentry.
