Keeping in shape is one of the best things you can do for your body and soul, especially in this time of lockdown. Here are some things to know about the body.
1. The human body is made up of 12 systems, which include: the cardiovascular, the digestive, the endocrine, the immune, the integumentary, the lymphatic, the muscular, the nervous, the reproductive, the respiratory, the skeletal, and the urinary system.
It takes all of these systems to keep the body working optimally. Let’s briefly talk about what these does:
- Cardiovascular – transports blood, oxygen, and nutrients throughout the body.
- Digestive – takes food and processes it .
- Endocrine – produces hormones to help you regulate metabolism, grow and develop, tissue function, sexual reproduction, sleep, and mood.
- Immune system – wards off infection.
- Integumentary – protects the body from outside damage.
- Lymphatic – connects the lymph nodes in our systems and helps the circulatory and immune systems.
- Muscular – increases our mobility.
- Nervous – puts signals through the body to control voluntary and involuntary actions.
- Reproductive – allows us to have sex and produce children.
- Respiratory – takes in oxygen and gets rid of carbon dioxide as we breathe.
- Skeletal – gives our bodies a framework and supports the systems.
Each system performs other functions as well.
2. The four main blood groups (A, B, AB, and O) are determined by the antibodies in your plasma and antigens found on your red blood cells. Antibodies are blood proteins. Antigens are activate an immune response and control what enters and exits a cell, which is important to knock out harmful foreign substances.
There are eight possible blood types, which can be positive or negative. There are eight different blood types, which feature either a positive or negative. The +/- part is found through the presence or absence of the Rh factor.
The interesting thing is our bodies can handle blood without the presence of an antigen that we usually have, but cannot handle the introduction of a new antigen into the circulatory system. Case and point: O-blood types can donate to anyone, because it’s universal. People with AB+, have every antigen in their blood already so they can receive blood from anyone.
3. Our DNA is stored in 23 pairs of chromosomes within the nucleus of every cell in our body.
Is cloning animals possible? Yes. Only a cell is needed because each one has a full set of chromosomes which contain all the genetic material needed to determine the makeup of our entire bodies (from our follicles to nails).
4. The antibodies and microphones in your immune system helps fight off of infection. The antibodies get rid of the foreign bacteria, while microphones are white blood cells that contain foreign objects and stop them from spreading an infection or disease.
5. Our bodies are unique because they feature amore non-human cells in our body than human ones.
Our bodies fight off infections everyday because there are ten times more bacteria cells in our bodies than our own human cells. The bacteria is harmless and makes it easier to digest food and drink. Even our DNA has eight retroviruses that were absorbed into our own genetic code at some point. These viral genes in our DNA help with reproduction and other functions.
