The brain and spinal cord form the central nervous system, which works to process and send nerve signals, interpret information, and produce conscious thought. The nervous system helps the body regulate every functionTrusted Source, including every other organ system. The nervous system also includes an extensive network of neurons throughout the b...
The reproductive system includes the organs that enable a person to reproduce and experience sexual pleasure. In females, the reproductive system also supports the growth of a fetus. The male reproductive systemorgans include: 1. the testes 2. the epididymis 3. the vas deferens 4. the ejaculatory ducts 5. the prostate gland 6. the seminal vesicles ...
The skin is the body’s largest organ. It is part of the integumentary system, which includes skin, hair, nails, and fat. The integumentary system helps regulate body temperature, protect the body from dangerous pathogens, make vitamin Dfrom sunlight, and provide sensory input. The skin comprises three layersTrusted Source: 1. The epidermis:This is ...
The muscular system includes a vast network of muscles. There are three types of muscles: 1. Skeletal muscles:These are voluntary muscles, meaning a person can decide when to move them. The biceps and triceps are examples of skeletal muscles. 2. Cardiac muscles:These are involuntary muscles that help the heart pump blood. 3. Smooth muscles:These ar...
The endocrine system is a network of glands throughout the body. These glands release important chemicals called hormones, which help regulatethe function of virtually every organ and organ system in the body. The endocrine system includes several major glands, including: 1. the pancreas 2. the thyroid 3. the adrenal glands 4. the pituitary 5. the ...
The immune system helps the body prevent infections and fights them off when they do occur. Many organs play a role in the immune system. For example, the skin prevents dangerous pathogens from entering the body, and the salivary glands release saliva that can help break down some dangerous sources of infection in food. The lymphatic system plays a...
The digestive systemTrusted Sourceis the group of organs that digest food, as well as the various structures within that release substances to aid digestion and absorption. It includes: 1. the mouth 2. the esophagus 3. the salivary glands 4. the gallbladder 5. the liver 6. the pancreas 7. the stomach 8. the small and large intestines 9. the appendi...
The circulatory system includes the many blood vessels circulating throughout the body. It includes veins, arteries, capillaries, venules, and arterioles. The lymphatic system is also part of the circulatory system. It helps maintain the body’s fluid balance by collecting excess fluid and other particles from the blood. Lymph nodes are present with...
