The Strongest Muscles and the Largest Human Body Parts
How well do you know your body? Can you name all the largest parts of your body? How about the strongest muscles? Let’s find out!
1.) What is the largest organ system in the human body?
The largest organ system in the human body is the “Intergumentary System”.
This system is responsible for protecting the body from most physical and environmental factors. The integument also includes appendages (sweat and sebaceous glands, hair, nails, and arrectores pili) Arrectores pili are tiny muscles at the root of each hair that cause goosebumps.
2.) What is the largest organ in the body?
The largest organ in the body is the skin which is part of the Intergumentary System. It is the largest external organ.
The skin’s functions include protecting (the body) against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, and the protection of vitamin B folates.
3.) What is the longest bone in the human body?
The longest bone in the human body is the femur.
In layman’s language, femur is known as the “thigh bone”. This bone is the most proximal (closest to the body) bone of the leg use in walking, running and jumping.
4.) What is the largest vein?
The largest vein is the Inferior Vena Cava or IVC.
The IVC is also known as the Posterior Vena Cava. This large vein carries de-oxygenated blood from the lower half of the body into the right atrium of the heart.
5.) What is the largest artery?
The largest artery in the human body is the ‘aorta’.
The aorta is the largest artery in the human body. This human body part originates from the left ventricle of the heart and extends down to the abdomen, where it branches off into two smaller arteries. The main function of the aorta is to distribute oxygenated blood to all parts of the body through the systemic circulation
6.) What is the largest internal organ?
The largest internal organ in the human body is the liver. The liver is also amazingly the heaviest organ, with an average of 1.6 kg.
This vital organ necessary for survival, which is responsible for detoxification, protein synthesis and others, is currently no way to compensate for the absence of liver function.
7.) What is the longest muscle in the human body?
The longest muscle is the Sartorius muscle. It is located in the thigh.
The Sartorius muscle is a long thin muscle that runs down the length of the thigh. Its upper portion forms the lateral border of the femoral triangle.
8.) What is the longest single nerve in the human body?
The longest single nerve is the ‘Sciatic Nerve’. It is also located in the thigh.
This nerve is also known as the ‘Ischiadic Nerve and the Ischiatic nerve. This large nerve fiber begins in the lower back and runs through the buttock and down the lower limb. The ‘Sciatic Nerve’ is the longest and widest single nerve in the human body.
What are the "strongest" human muscles?
The Masseter or commonly known as jaw is recognized by the Guinness Book of Records as the strongest muscle. The achievement of bite strength of 4,337 N was the basis for this record.
2.) Quadriceps femoris
The strongest muscle of the body is usually said to be the quadriceps femoris which is also known as the gluteus maximus. This muscle is estimated to produce more than 100 watts for a few minutes.
3.) Myometrial Layer of the Uterus
The Myometrial Layer of the Uterus is said to be the ‘pound for pound” king of all muscles. It is the strongest muscle by weight in the human body. At the time when an infant is delivered, the entire human uterus weighs about 1.1 kg. During childbirth, the uterus exerts 100 to 400 N (25 to 100 lbf) of downward force with each contraction.
4.) External Muscles of the Eye
It is frequently said that the external muscles of the eye are very strong in relation to the small size and weight of the eyeball. They are considered the strongest for the job they have to do and are sometimes claimed to be "100 times stronger than they need to be.”
In some aspect, the heart is regarded as the strongest muscle in the human body. The power output of the human heart ranges from 1-5 watts making it one of the strongest muscles if not the strongest. Very low but the heart performs the largest quantity of physical work in the course of a lifetime. An output of one watt continuously for eighty years yields a total work output of two and a half gigajoules.
Others claim that the strongest muscle in the body is the tongue. This is an erroneous statement because the tongue consists of 16 muscles, not one.
