In this video, you will learn about the Circulatory SystemThe circulatory system, is the transportation system of the body and is responsible for the flow of blood in the body. The major structures that make this possible are the heart, blood vessels, and blood.
The heart pumps blood in order to move nutrients oxygen, carbon dioxide disease-fighting white blood cells, and hormones to and from the cells in the body
The circulatory system has two main types of circulation.

The pulmonary
The Systemic
Pulmonary circulation travels from heart to the lung where your blood picks up oxygen and back to the heart
Systemic circulation is from the heart to the body

Your heart has four chambers that is used to pump blood throughout your body.

Two Atria - which are the upper chambers.
Two ventricles - these are the lower chambers
The left and right side of the heart is divided by the septum

Blood Vessels carry blood throughout the body.
Arteries carry blood away from the heart and veins carry blood towards the heart

Capillaries, which are the smallest blood vessels in the body create a network of vessels connecting veins and arteries.
In summary, the heart pumps blood to the body through the arteries and returns blood to the Body through the veins

You have around 1.5 gallons of blood in your body
It is composed of several different types of cells.
The first type of blood cell is the red blood cell. Red blood cells help carry oxygen

The second type of blood cell is known as the white blood cell and helps fight pathogens

The third type of cell is the platelet and create blood clots.
These blood cells are found in a liquid called plasma which consists of water along with electrolytes and some proteins and hormones

In summary, The job of the circulatory system is to circulate blood to and from cells in the body in order to transport nutrients and oxygen and remove carbon dioxide and waste.

An oblique triangle is a triangle without a 90 degree angle.
The form for area for an oblique triangle equals 1/2 b * c (sin A)
The equation gives us a way to find the area of the triangle without needing to find the height of the triangle.
This means we can find the area of oblique triangles without needing to create right triangles.

The sodium-potassium pump is a type of active transport that moves 3 sodium ions into the cell and 2 potassium ions out of the cell. I cover why the pump is needed and provides an overview of this type of active transport cells use to move important objects into and out of the cell.
ATP is used to change the shape of the carrier protein allowing the sodium and potassium to move across te cell membrane.

I use a factor tree in order to find the cube root of 216.
This video is part of a playlist of finding the cube root of numbers 1 through 50

Learn how to solve problems involving Boyle's law. Boyle's law states that as pressure increases then volume decreases and pressure decreases volume increases.
I use the Boyle's law formula Pressure x Volume = K
Example problem:
3.00 L of a gas is at 740.0 mmHg pressure. What is its volume at standard pressure?

A gas occupies 12.3 liters at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg?

The spleen is located in the upper left abdominal cavity, just beneath the diaphragm, and next to the stomach. It is similar to a lymph node in shape and structure but it is much larger.
An easy way to remember the anatomy of the spleen is the 1×3×5×7×9×11 rule. The spleen is 1" by 3" by 5", weighs approximately 7 oz, and lies between the 9th and 11th ribs on the left-hand side.
Your spleen is considered part of the lymphatic system.

the spleen consists of two types of tissue called white pulp and red pulp. The white pulp is lymphatic tissue consisting mainly of lymphocytes around arteries. The red pulp consists of sinuses filled with blood and lymphatic cells,

As blood is filtered through the spleen old and damaged red blood cells are removed from the blood. In addition, the spleen produces lymphocytes in response to invading pathogens found in the blood. The spleen is like a large lymph node that filters blood instead of lymph looking for invaders like harmful bacteria. White blood cells stored in the spleen help remove and eliminate these invaders. It is particularly helpful when fighting meningitis and pneumonia

The spleen also stores blood. The sinuses in the red pulp of the spleen are filled with blood and can be used in case of an emergency.

You can live without your spleen. your immune system won’t shut down without a spleen, but it won’t operate as efficiently.

Nervous System controls the human body by sending electrical signal through out your body.
The nervous system can be divided into the central nervous system and the peripheral nervous system.

By using the formula pi times radius squared times height you can calculate the volume of a cylinder.
I also cover how to calculate height if you are given the radius and volume and how to calculate the radius.

The exterior angles of a polygon are angles drawn from an adjacent side. The exterior angles also add up to 360 degrees.The interior and exterior angles add to 180 degrees.
