Top 10 Body Functions.

The human body performs millions of functions daily, and all these body functions combined make you the person you are today. Here are some of the top 10 body functions that form the foundation of what makes your body work so efficiently every day.

1) Digestion.

The human body is a miracle of engineering, made up of a myriad of functional parts. Digestion is one of these important functions that allow our bodies to get nutrients from what we eat. It can be broken down into two distinct processes: mechanical digestion and chemical digestion. Mechanical digestion begins when food travels from your mouth to your stomach, where enzymes begin breaking it down into smaller molecules in preparation for a further breakdown during chemical digestion.

2) Circulation.

Blood carries oxygen and nutrients to your cells, as well as picking up waste products like carbon dioxide. The heart pumps blood around your body using pulsing waves of muscle contractions. These pulses occur at regular intervals, and without them, you wouldn’t be able to survive. Blood pressure is also essential in circulation – if it’s too high or too low, vital organs can be damaged. In some cases of severe hypotension or hypertension, even death can occur.

3) Excretion.

When you sweat, it cools your body down. Sweat is mostly water, with a small amount of sodium, potassium, and chloride (like table salt). The kidneys filter out waste products from our blood, such as urea and uric acid. These get released into our urine. Another way we get rid of waste products is when we throw up. This means that bile from our liver goes into our intestines where it mixes with food before being excreted in your poo.

4) Respiration.

The respiratory system is made up of several important organs, including your lungs, bronchi, and trachea. Respiration involves moving oxygen into and carbon dioxide out of your body to create energy. This process takes place through respiration; you breathe in air that contains oxygen, which enters your body through your nose or mouth and travels down your windpipe (trachea) to reach your lungs.

5) Blood Cell Production.

Blood cells include red blood cells, white blood cells, and platelets. They’re produced in the bone marrow where they go through a series of steps known as maturation (maturation), release (release), and circulation (circulation). Blood cell production is an important body function that helps fight infections and repair damaged tissue.

6) Reproduction.

The primary body function of both males and females is reproduction. The main biological purpose for men and women is to pass their genes on to a new generation, to continue evolution. Reproduction involves two processes: sexual intercourse and pregnancy. Men produce sperm, while women release an egg or ovum (via ovulation). A man can have sex with a woman several times during a single reproductive cycle.

7) Nervous System.

The nervous system, also known as our brain and nervous system, has two main jobs: (1) sends signals to our body so that we can move and (2) sends signals from our body back to our brain so that we can feel what is going on inside us. The nervous system is like a bunch of wires that connect your brain to your body so you can move around.

8) Endocrine System.

The endocrine system is a network of glands that secretes hormones into your bloodstream. It helps to maintain homeostasis (balance) by regulating body temperature, blood pressure, and water and electrolyte balance, for example. Its key components are your hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid glands, thymus gland, and adrenal glands.

9) Sensory Organs (Eyes, Ears, Nose, and Tongue)

Our sensory organs—eyes, ears, nose, and tongue—are all responsible for gathering information from our environment. Think of these body parts as cameras or antennae, or machines that collect data and send it to our brains. From there, we use logic and reason to make sense of it all.

10) Immunity (Defence System against foreign bodies and microbes/bacteria).

The immune system is comprised of many different organs that are all designed to protect our body from foreign bodies and harmful microbes and bacteria. The most well-known components of our immune system are white blood cells, but it also includes organs such as the thymus, lymph nodes, bone marrow, tonsils, and spleen.
