The 11 Organ Systems

Our bodies are composed of different tissues and structures. An organ system is a group of organs that work together to perform complex functions. We can divide our body into 11 different organ systems. For those of you starting university this Autumn, this will be very beneficial in helping you understand the basics of anatomy. If you are not a uni student, fear not! These posts will widen your understanding of the human body. Here we will give you a brief overview of each system. Check back each week where we will be looking at each system in greater detail!

Nervous system

The nervous system is composed of our brain and spinal cord. It is responsible for how we interact with and respond to our environment. It controls the function of the organs in the other body systems. Check back next week where we will be delving more into the nervous system!

Cardiovascular system

This is comprised of the circulatory system and the heart. Our heart is a powerful organ, and keeping our blood pumping is very important. It works alongside our array of vessels such as arteries, veins, capillaries, and venules to carry blood around our body.

Lymphatic system

The lymphatic system is made up of lymphatic vessels that drain lymph, an excess of tissue fluid. Overall, it removes waste and toxins from the body and helps in the body's defence system.

Respiratory system

The respiratory system is important for transporting oxygen in and around our body and removing waste carbon dioxide. It consists of the nasal cavity, pharynx, larynx, bronchi, bronchioles, alveoli, and lungs. If you can’t wait for our post on the respiratory system, head along to one of our events where you will have an opportunity to dissect these organs for yourself!

Integumentary system

The integumentary system basically means your skin! It also encompasses sweat glands and sensory receptors.

Endocrine system

The endocrine system is made up of glands all over the body that produce hormones. These hormones regulate a variety of functions such as metabolism or the menstrual cycle.

Gastrointestinal system

This is commonly known as our digestive system! There are a lot of organs in our digestive tract such as the stomach, and small and large intestines. The chewing of food and making it into smaller components is essential for maintaining the human body. The absorption of food makes energy. At The Murder of Anton Orlov, you get to see the inside of your abdomen up close and personal.

Urinary System

The urinary system is involved in producing and excreting urine. It is comprised of the kidneys, ureters, bladder, and urethra. The kidneys are very important organs as they filter blood and remove waste in the form of urine. We will delve more into these organs in a few blog posts time!

Muscular system

Your body has many different muscles with many different functions. There are three types of muscle. Smooth, cardiac, and skeletal! These muscles either act under voluntary or involuntary control.

Skeletal system

The skeletal system is composed of bones and cartilage. Understanding the skeleton is important to help us get to terms with how the body moves, how it protects our organs, and how muscles attach to it.

Reproductive system

The reproductive system of course varies between males and females. We will be exploring these different organs and their functions at a later date.
