Anatomy

What is Anatomy?

Anatomy is the study of the structure of human body. It is the  science that concerns itself with the structure of body of  humans, animals, and other living organisms.

 

Human Body

This is what make a human, human and other living organisms.The human body is everything that makes up human being and other living organisms. There are major  parts of human body which are the head, neck, torso, arms and legs.

 

Body systems

The body system consists of some important systems that makes every day living of humans to be possible. They are systems that are assigned to carry out some important functions in our body These systems are all working together and made up of what we call human body


The following are the important systems in Human body

1. Circulatory System
2. Digestive System
3. Nervous System
4. Reproductive System
5. Muscular System
6. Skeletal System
7.Respiratory System

8.   Urinary System

9.   Endocrine System

10. Immune System

11. Lymphatic System and

12.  Skin, Or Integumentary System

 

Here are the brief explanations on each of the systems

 

1 The Skeletal System: 

The skeletal system helps in the movement of the body and 

the production of of blood cells. This system consists of bones

 that are present in our body. They can be found in different

 joint parts of our body system. The help in the flexibility of our

 body

 

 

2 The Circulatory System: 

The circulatory system consists of the heart, blood, blood

 vessels, arteries and veins. They are responsible for moving

 and transporting of the blood, oxygen and nutrients in the

 body. They also ensure they  are well circulated throughout

 the body.


3 The skin

The skin protect  the body from any external harm. it is the

 system that also protect and prevent us from contacting any

 harmful diseases. It is the system that is responsible for

 regulating our body temperature and prevent the body against

 harmful bacterial.

 

4.  The Digestive System

The digestive system is responsible for the breaking

 down of food and removal of waste from our body. The 

digestive system includes:

the mouth, esophagus, stomach, small intestine,

 large intestine, rectum, and anus, the liver and the pancreas 

 

5  The Nervous System:


The central nervous system includes the brain and spinal cord.

 The peripheral nervous system consists of nerves that

 connect every other part of the body to the central nervous

 system. The nervous system helps in controlling all our

 actions like breathing and movement of the body or

 movement from one place to the other.


6  The Reproductive System:

The reproductive system helps in producing  new offspring. It

 consists of both male and female reproductive systems. The 

male reproductive system includes the penis and the testes,

which produce sperm. The female reproductive system

consists of the vagina, the uterus and the ovaries, which 

produce eggs.

 

7  The Muscular System:

The Muscular System contains body muscles that help

 in the body movement, blood flow and other bodily functions.

There are three types of muscle: Skeletal Muscle which is

 connected to bone and helps with voluntary movement,

 Smooth Muscle which is found inside organs and helps to

 move substances through organs, and Cardiac Muscle which

 is found in the heart and helps pump blood.


8  The Respiratory System

The respiratory system helps in breathing in and out.

It helps us to take in vital oxygen and expel carbon dioxide

 in a process we call breathing. It consists mainly of the nose,

 the trachea, the diaphragm and the lungs.

 

9 The Urinary System:

The Urinary System helps to eliminate a waste product called

 urea from the body, which is produced when certain foods are

 broken down. The urinary system includes two kidneys, two

 ureters, the bladder, two sphincter muscles and the urethra.

 Urine produced by the kidneys travels down the ureters to the

 bladder, and exits the body through the urethra.

 

10 The endocrine System:

It consists of eight major glands that secrete hormones into

 the blood. They are: Pineal

 gland, Parathyroid glands, Adrenal glands, Pituitary glands

 and Thyroid gland.

 

11.  The Immune System: 

This defends body against bacteria, viruses and other

 pathogens that may be harmful. It includes lymph nodes, the

 spleen, bone marrow, lymphocytes, the thymus and

 leukocytes, which are white blood cells.

 

12.  The Lymphatic System: 

This system helps the body fight infection.

 It also removes excess lymph fluid from bodily tissues, and

 returns it to the blood. It includes lymph nodes, lymph ducts

 and lymph vessels.
