I love you with my heart, my brain, and my lungs
Are you ready to get to know your body from the inside?
start
Our body is capable of performing many actions, from eating to sighing or reacting to a stimulus. The possibilities are endless! But what makes our body work?
The bones in our body contain bone marrow inside. That’s where stem cells are born.

CIRCULATORY SYSTEM
The Circulatory System is responsible for distributing oxygenated blood from the heart to all the organs in the body. On its journey, it collects deoxygenated blood and carries it back to the lungs, where it becomes oxygenated again and… back to the heart! It is made up of:
- the heart
- the blood vessels:
- arteries, veins, and capillaries

THE HEART
It’s a muscle made up of four chambers that, through their contractions, allow the movement of blood. Those contractions are what we call the pumping of blood!
Fun facts:
When we say we hear the sound of the heart, we’re actually hearing the closing of the heart valves. It only takes 20 seconds for blood to travel throughout the entire body.
NERVOUS SYSTEM
This system is responsible for receiving internal and external information from the body and processing it. Its goal is to regulate the functioning of the body's organs and systems. What it does is:
Receive information. Process that information. Generate responses. Coordinate the body to respond. Provide the basis for cognition (reasoning and awareness).

THE SPINAL CORD
During childhood, we have 33 vertebrae, but only 24 as adults, since the bones of the coccyx and the sacrum fuse together.
What it does is: transmit messages to and from the brain. It is protected by the vertebrae of the spinal column.

SKELETAL SYSTem
The Skeletal System (SS) is made up of bone tissue (206 bones) and cartilaginous tissue. The functions of the Skeletal System are:
- Protecting the organs.
- Giving shape and support to the human body (skeleton).
- Enabling movement, together with the muscles.
- Storing calcium, phosphorus, and some lipids.
next
TYPES OF BONES:
Teeth are not part of the Skeletal System.
Bones are classified according to their shape. They can be: long (the longest is the femur), short, flat, and irregular.
Short bones: They are covered by articular cartilage. They are usually joined to other bones to form movable joints.
Long bones: In this regard, they are composed of the diaphysis, two epiphyses, the medullary cavity, the periosteum, and the endosteum.
Irregular bones: Like the vertebrae or the jawbone.
Flat bones: They are broad and flat. They protect the body’s internal organs.
next
MUSCULAR SYSTEM
The Muscular System (MS) is made up of cells that contract to maintain posture, allow movement, enable changes in shape, and propel fluids through hollow organs. The properties of the Muscular System are:
- Excitability
- Contractility
- Elasticity
- Extensibility
- Plasticity

Muscle tissue can be:
It allows slow and relatively weak involuntary contractions. These muscles line the intestines, uterus, bladder, and respiratory system.
It allows strong and rhythmic contractions. Its main function is to pump oxygenated blood so it reaches all the organs of the body.
They are the only muscles under voluntary control. They are attached to the skeleton and allow the movement of the bones.

CONGRATULATIONS!
After this masterclass, it’s clear that you have a better understanding of how your body works. You now have the full capacity to know what type of muscle covers your organs 😉 and which cells heal your wounds.
If you want to expand your knowledge, you have a whole arsenal of tools at your disposal 👇
Bone cells:
Osteoclasts: They are cells with multiple nuclei. Their function is to reabsorb bone, and they are essential for bone repair.
Osteoblasts: These cells live between 1 and 10 weeks and transform into osteocytes (15%), lining cells, or die.
- They synthesize the bone matrix, so they are involved in the growth and maintenance of bones.
Osteocytes: These cells live for about 25 years. They make up between 90% and 95% of the cells in bone tissue.
- They regulate calcium concentration and stimulate the maintenance of bone.
Epífisis
Cavidad medular
Diáfisis
Epífisis
Blood cells
They can be of different types depending on their function:
- Red blood cells (erythrocytes)
They carry oxygen from the lungs to the tissues and carbon dioxide back to the lungs.
- White blood cells (leukocytes)
They are part of the immune system and fight infections.
These are the cells that fight bleeding and act in case of injury.
It transports water, nutrients, minerals, medications, and hormones throughout the body.
Neural cells
They can be of different types depending on their function:
Neurons are made up of a cell nucleus, dendrites, and a single extension (per cell) that transmits nerve signals, called an axon. When axons come together, they form nerves.
Dendrites
Cell nucleus
Cell body or soma
Axon
Stem cells
Stem cells are cells that are born as a blank slate; over time, they specialize and become cells with different functions. They can be:
- Blood cells
- Neural cells
- Bone cells
- Muscle cells
- And the specific cells of each organ
Muscle cells
The cells of the Muscular System are known as muscle fibers.
- They are cylindrical cells with multiple nuclei.
- A muscle fiber is made up of many myofibrils.
