The digestive system, also called the gastrointestinal tract, is made up of the following starting at the mouth, esophagus, stomach, small intestines, large intestines, and finally ending at the anus (professional, 2021). the digestive system breaks down foods and absorbs the nutrients from the food we eat into the bloodstream through different enzymes released during the process. The organs that the digestive system interacts with along the journey are the pancreas, gallbladder, and liver, all of which help break down food. The liver processes nutrients absorbed from the small intestines and then makes chemicals used in our bodies with the material the small intestine absorbs). Finally, it enters the large intestine (colon), preparing to be emptied from bowls (C.C. Medical Professionals, 2021).

The circulatory system comprises the heart and blood vessels, sometimes called the cardiovascular system (C.C. Medical Professionals, 2021). The circulatory system's primary process is to deliver oxygen, nutrients, and hormones to tissue, muscles, and organs within our body. Blood is pumped from our heart to our lungs to get oxygen, and then oxygenated blood is sent through our arteries to the rest of the body from our heart. Our Veins carry oxygen-poor blood back to the heart and repeat the process (C.C. Medical Professionals, 2021).

The respiratory system is the organs and tissue that allow us to breathe and consists of our airways, lungs, and blood vessels, which assist in moving oxygen through our bodies while removing waste such as carbon dioxide (C.C. Medical Professionals, 2020). The primary function of this system is gas exchange between oxygen in the air, which is absorbed into our blood, and carbon dioxide, released from our blood into the air. Regulation of Ph levels in the bloodstream controls our bodies' carbon dioxide.

The musculoskeletal system, which includes the body's bones, muscles, joints, ligaments, tendons, cartilage, and soft tissue, makes up this system. This system supports the body's weight when movement occurs (C.C. Medical Professionals, 2020). The body's nervous system interacts with the skeletal system for the action to happen by sending messages from the brain to the muscles. Once this occurs, the muscle fibers respond by contracting, which causes the tendon to be pulled, which then moves the bone attached to the muscle, which is now voluntary (C.C. Medical Professionals, 2020).

The nervous system uses the nerve cells or neurons within the nerve cells to transport messages out to every part of the body, allowing a person to feel, hear, move, blink, cough, etc. The nervous system has three nerve types that have specific jobs (C.C. Medical Professionals, 2023). They are motor neurons that help the body with movement, sensory neurons that relay messages to the brain from things we see, hear, taste, and feel, and last, the interneurons that help a person remember something, learn, and think.

The immune system attacks foreign substances when the body is sick or injured (C.C. Medical Professionals, 2023). It destroys them and promotes healing from sickness or injury, whether it is from a virus or a physical wound from injury. The immune system fights off and against bacteria, viruses, and infections. this system is the body's first line of defense when you are sick or hurt. What makes this system up are all of the following :

* White blood cells that attack and destroy

bacteria and viruses that enter the body.

• Antibodies are proteins that protect against germs that can harm the body by attacking and destroying them.

• Cytokines are the chemical messengers that tell the immune system cells where and what to do.

• Complement system, which are proteins that group and support and promote healing.

• Lymph nodes that assist in sifting the waist or toxins out of the body.

• The spleen filters blood and reuses cells that are damaged to make new cells in addition, the spleen houses white blood cells that protect you from harmful viruses and bacteria.

• Tonsils and adenoids that can capture invaders upon entry to the body are located in the throat and nose area.

• The thymus helps the growth and maturity of T cells by housing them before they are released into the body.

• Bone marrow makes the body's blood cells sustain life, and white blood cells are a crucial part of the body's immune system in fighting off bacteria and viruses.

• Skin helps to protect from germs entering the body by producing oil that makes it harder for germs to enter.

• Mucosa lines the body's organs and produces mucus that captures germs for your body to get rid of (C.C. Medical Professionals, 2023).

The female reproductive system or the ovarian reproductive system, consists of all of the following (Fowler et al., 2022).

• The clitoris is a female sensory organ.

• Mons Pubis is the area or region of fat that lies over the pubic bone.

• Labia Majora which blankets over the labia minora and also houses the sebaceous glands.

• Labia Minora which covers the vestibule.

• Greater Vestibular Glands which are responsible for vaginal lubrication and secretions of mucus.

• Breast, which is where milk is produced and released.

• Ovaries are where eggs are produced.

• Oviducts transfer the eggs to the area or region where fertilization occurs in the uterus.

• The Uterus is where the embryo is located during development.

• The vagina is the most specific area or region where intercourse takes place, in addition to being the birthing canal and the canal where the menstrual cycle flows through.

The male reproductive system, also called the testicular reproductive system, includes all of the following (Fowler et al., 2023):

• The Scrotum is what controls not only the temperature of the testes but also supports them as well.

• The Penis is an organ that copulates and releases urine which disposes of waste.

• The testes produce hormones similar to those in the endocrine system, in addition to sperm.

• The Saminal Vesslels provide and assist in the production of semen.

• The Prostate Gland also assists in semen production.

• The Bulbbouretharal offsets the urine in the urethra, neutralizing it (Fowler et al., 2023).
