I forgot to include the following statements. Thank you for your help.

1)A Jewish council was established to regulate the internal life of the ghetto.
2)Jews were regularly sent to either a concentration camp or a death camp.
After Kristallnacht the number of Jews sent (deported?) to concentration camps increased.
3)Prisoners were forced to do hard physical labour and were givn tiny rations. They were also forced to sleep on wooden bunks.
4) In some camps doctors conducte medical experiments on prisoners against their will.
5) While concentration camps were meant to work and starve prisoners to death, extermination camps were built for the sole purpose of killing large groups of people quickly and efficiently.
6) The Nazis built six extermination camps. Prisoners were told to undress to take a shower. Rather than take a shower, prisoners were herded into gas chambers and killed.
7) Ausschwitz was the largest concentration and extermination camp built. It is extimate that 1.1 (one point one) millione people were killed at Auschitz.

Check for commas that are needed and the spelling of a few words.

Thank you for providing additional statements. Here is the explanation for each statement:

1) A Jewish council was established to regulate the internal life of the ghetto.
During the Holocaust, the Nazis created ghettos where they forced Jews to live in crowded and segregated areas. In order to control and manage these ghettos, the Nazis established Jewish councils, also known as Judenräte. These councils were responsible for enforcing Nazi orders within the ghetto and organizing internal affairs such as sanitation, housing, and food distribution.

2) Jews were regularly sent to either a concentration camp or a death camp.
During the Holocaust, the Nazis established both concentration camps and extermination camps. Jews and other targeted groups were often sent to these camps. Concentration camps were intended for forced labor, while extermination camps were designed solely for the purpose of mass killings.

After Kristallnacht, the number of Jews sent (deported?) to concentration camps increased.
Kristallnacht, also known as the Night of Broken Glass, was a violent pogrom against Jews in Nazi Germany and Austria on November 9-10, 1938. Following this event, the Nazi regime escalated its persecution of Jews, which included increased deportations to concentration camps.

3) Prisoners were forced to do hard physical labor and were given tiny rations. They were also forced to sleep on wooden bunks.
Conditions in concentration camps were harsh and inhumane. Prisoners were subjected to grueling physical labor, often under brutal conditions. They were given meager rations of food, which were insufficient for their survival. The sleeping arrangements in the camps typically consisted of wooden bunks or overcrowded barracks, offering little comfort or privacy.

4) In some camps, doctors conducted medical experiments on prisoners against their will.
The Nazis carried out various horrific medical experiments on prisoners within concentration camps. These experiments included testing the limits of the human body, sterilization experiments, and the development of new medical techniques. These experiments were conducted without the consent of the prisoners and often resulted in severe physical suffering, permanent disability, or death.

5) While concentration camps were meant to work and starve prisoners to death, extermination camps were built for the sole purpose of killing large groups of people quickly and efficiently.
Concentration camps were primarily used for forced labor, where prisoners were systematically worked, starved, and subjected to harsh conditions, leading to death through exhaustion, malnutrition, or disease. On the other hand, extermination camps, also known as death camps, were purposefully constructed to efficiently and systematically kill large numbers of people, predominantly Jews, through methods such as gas chambers.

6) The Nazis built six extermination camps. Prisoners were told to undress to take a shower. Rather than take a shower, prisoners were herded into gas chambers and killed.
The Nazis established six extermination camps as part of their systematic plan for genocide. These camps were designed to eliminate as many people as efficiently as possible. To deceive the victims, the Nazis would tell them they were going to take a shower. However, instead of being led to a shower, they were herded into gas chambers, where they would be killed using poisonous gas, such as Zyklon B.

7) Auschwitz was the largest concentration and extermination camp built. It is estimated that 1.1 (one point one) million people were killed at Auschwitz.
Auschwitz, located in German-occupied Poland, was the largest and deadliest concentration and extermination camp built by the Nazis. It consisted of three main camps, Auschwitz I, Auschwitz II-Birkenau, and Auschwitz III-Monowitz. It is estimated that approximately 1.1 million people, mostly Jews, were brutally murdered at Auschwitz through various means such as gassing, shooting, starvation, and disease.
