Biology MineralsIn this video I will discuss 15 important minerals of the human body. A mineral is an inorganic nutrient which means it lacks carbon. Minerals build cells, take part in chemical reactions, send nerve impulses, and carry oxygen. Your body cannot produce any of the minerals that it needs. Instead, you must get minerals from the foods you eat.
Minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids.
Macrominerals are used in large quantities
Trace minerals are used in very small amounts
List of 15 minerals covered
Potassium
Chlorine
Manganese
Copper

**** Sorry I made a mistake at 00:49 I incorrectly label and describe the thigh adductors as hip abductors. The thigh adductors pull the legs together when they contract.*******

I cover many of the major muscles of the human body.
The Pectoralis major: is a thick, fan-shaped muscle, situated at the chest of the human body.
The Bicep is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Its main function is to flexes and twists the forearm.

The abdominal muscles support the trunk, allow movement and hold organs in place

The sartorius muscle is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh This muscle helps you cross your legs

The abductor muscle group is located on the lateral side of the thigh and moves the thigh away from the body’s midline.

The trapezius muscle resembles a trapezoid or diamond-shaped quadrilateral
It helps support the weight of the arm and move the shoulder

The Deltoid forms the rounded contour of the human shoulder. It is a prime mover of arm

The latissimus dorsi is the largest muscle in the upper body.It is responsible for extension, adduction, internal rotation of the shoulder. This muscle helps you do pull ups at the gym.

The serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest. It acts to pull the scapula forward around the thorax.

External oblique The external oblique functions to pull the chest downwards and compress the abdominal cavity, It also performs (same side) side-bending and (opposite side) rotation

The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. For example, using a hammer.

Finger extensions include 9 extensor muscles found in the posterior side of the forearm and extend the hand and fingers.

Finger flexors help you close your hand

Quadriceps is a large muscle group that includes the four prevailing muscles on the front of the thigh. These muscles are the great extensor muscle of the knee

Hamstrings a hamstring is one of the three posterior thigh muscles in between the hip and the knee The hamstrings cross and act upon two joints – the hip and the knee

The gastrocnemius forms half of the calf muscle. Its function is flexing the foot at the ankle joint and flexes the leg at the knee joint.

Tibialis anterior It is responsible for flexing the foot backward and inverting the foot.

The soleus is a powerful muscle in the back part of the lower leg aka (the calf). It runs from just below the knee to the heel, and is involved in standing and walking.

The infraspinatus muscle is a thick triangular muscle It is one of the four muscles of the rotator cuff, it’s main function is to rotate the humerus and stabilize the shoulder joint.

The teres major helps rotate the humerus and assists the latissimus dorsi in drawing the previously raised humerus downwards and backward.

Triceps is a large muscle on the back of the upper arm It is responsible for straightening the arm.

The gluteus medius is a muscle that helps with hip movement

When you walk and run it aids in stabilizing your pelvis, in particular when you perform activities where you balance on a single leg.

Gluteus maximus is the main extensor muscle of the hip You use the gluteus maximus when you stand up from a chair, sprint, run, and go up steps.

Correction:
0:49 Sorry I made a mistake. The muscles in dark blue, labeled as “abductors”, are in fact the “Adductor” group. They are the muscles that draw your legs toward the midline and assist with medial rotation also known as crossing your legs.

Mountains can form through folding, volcanism, and faulting.
Folded mountains form when rock layers are squeezed together and are pushed upward.
Many folded mountains occur at convergent boundaries where continental crust collide
The Himalayas stretch through the borders of China, Nepal, India, and Pakistan is the most towering mountain range on Earth,
Volcanic mountains are created when melted rock erupts onto the earth’s surface. Many volcanic mountains occur at convergent boundaries. Most of the active volcanoes on earth are concentrated around the edge of the pacific ocean.
Fault block mountains form when tension causes the lithosphere to break into normal faults.
At normal faults, the lithosphere drops down. The pieces left standing form fault-block mountains.

Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion.
In this video, I focus on three ways heat can be transferred,
Conduction, Convection, and Radiation.
Conduction involves direct contact between objects and usually occurs among solids.

Convection is caused by unequal heating and the density of the different objects causes movement of fluid away from the heat source.

Radiation occurs without objects touching and occurs in space.
For example, the energy of the sun warms objects on Earth due to radiation.

I show several examples or demonstrations for each type of heat transfer.

Conduction, Convection, Radiation

Difference between Organic and Inorganic Compounds
Organic compounds contain carbon. There are at least four important organic compounds, lipids, proteins, carbohydrates, and nucleic acids.
Inorganic compounds do not contain carbon and usually are more simple compounds.
There are some compounds that contain carbon and are inorganic like carbon dioxide.

Learn the difference between prime and composite numbers. All whole numbers greater than one can be classified as prime or composite numbers.
Prime numbers have only factors one and itself. A composite number has other factors other than itself and one. So let's look at some examples. Let's look at 4 and 5
Four is divisible by 1 and four is divisible by 2 so four is a composite number
5 is divisible by 1 but it is odd so it is not divisible by 2 or any other number so 5 is prime.

How do we breathe? The lungs and diaphragm work together to bring oxygen into the lungs and to move carbon dioxide out of your lungs.
The diaphragm is a large muscle that is found under your lungs. Your lungs are actually composed of millions of tiny air sacs and depend on the diaphragm in order to inflate
Your rib cage also helps out by having cartilage which allows the rib cage to expand and contract.
When you take a deep breath your diaphragm moves down and a low-pressure area is created and air flows into your nose and mouth. This process is your respiratory system hard at work.
Air enters the nose and mouth and enters the nasal passages.
Your nose and nasal passages have tiny hairs called cilia and mucus that help filter dirt and pollen out of the air.
The air next moves to the pharynx which is located at (the back of the mouth)
From the pharynx, it moves to the larynx which is commonly called the voice box.
the voice box (makes sounds when air
passes over the vocal cords)
Epiglottis: the flap of connective tissue that covers
over the larynx during breathing
It stands open during breathing, allowing air into the larynx. During swallowing, it closes to prevent choking on food

From the larynx, air travels to the Trachea which is a rigid tube made of cartilage.
The trachea leads into two tubes called the left and right bronchus
These tubes continue to branch until you reach a tiny air sac called a alveoli
At the alveoli, oxygen diffuses into the capillaries and carbon dioxide diffuse into the alveoli and is exhaled.
As you exhale the diaphragm moves upward and carbon dioxide and airflows out.

Difference between convex and concave Quadrilaterals.
A quadrilateral is a polygon so the same rules apply for a convex polygon.
A convex quadrilateral does not have angles greater than 180 degrees.
A concave quadrilateral has angles greater than 180 degrees.

After passing through the small intestine food travels into the large intestine.
Your large intestine is roughly 9 feet in length but gets it’s name because it has a larger diameter than the small intestine.
Your large intestine is also called the colon.
The large intestine is divided into several sections.
