The Brain

The brain is one of the most important organs in the human body and is responsible for major actions performed by the body. The brain is the one that allows you to think and make control of the other body parts. The brain is divided into four major lobes and each lobe performs specific functions.

FOUR DISTINCTIVE PARTS OF THE BRAIN

1. OCCIPITAL LO​BE- Location: back of the brain, Functions: seeing

2. FRONTAL LOBE- Location: front part of the brain, Functions: responsible for

3. PARIETAL LOBE- Location: topmost part of the brain, Functions: touch, pressure, temperature, and pain

4. TEMPORAL LOBE- Location: Below the parietal lobe, Functions: responsible for the perception and recognition of auditory and memory

The Heart

Heart- Location: hollow, muscular, organ located in the chest cavity between the lungs. Functions: to pump blood through the blood vessels

*The blood needs to circulate in order to put oxygen into the blood and take the carbon dioxide out from the body.

*The heart is surrounded by a fluid-filled sac called PERICARDIUM.​

​

The Heart

OXYGENATED BLOOD- blood with oxygen

UNOXYGENATED BLOOD- blood without oxygen

AORTA- the major artery of the body

VENA CAVA- the major veins of the body​

*oxygenated blood is pumped away from the heart through the arteries and returns to the heart without oxygen​

​

Chambers of the Heart​

The heart is divided into two halves by the SEPTUM.

UPPER TWO CHAMBERS- atria (it receive blood from the different parts of the body and lungs)

TWO LOWER CHAMBERS- ventricles (pump blood from the heart toward the different parts of the body and lungs)

​

​

The Heart Wall

The heart is lined with a connective tissue called ENDOTHELIUM OR ENDOCARDIUM (allows the heart to contract and beat)

​

The Heart​

CARDIACL CYCLE- sequence of heartbeat occur

TWO MAJOR PHASES

Diastole- the atria and ventricles are relaxed as the blood flows into the atria and ventricles

Systole- the ventricles contract, sending blood to the rest of the body

​

The Lungs

Our chest contains a pair of lungs, which are made up of sections called LOBES.

Location: left and right side (*because lungs are soft they are protected by the RIBCAGE)

Functions: combine oxygen with the blood and to separate carbon dioxide from the blood​

Subject | Subject

​

The Lungs

DIAPHRAGM- Location: under the lungs and it separates the lungs from the other internal organs Functions: largest muscle/ most efficient for breathing

INHALATION or INSPIRATION- the diaphragm flattens or moves downward

EXHALATION or EXPIRATION- the diaphragm relaxes​

The Liver

Liver- Location: right side of the abdominal cavity below the diaphragm Functions: filtering machine of the body/ remove toxins from the blood/ to break down excess protein (amino acid)/ maintain cholesterol and glucose (sugar) levels/ secrete chemical substances

​

The Liver

The Liver Makes Bile- the liver secretes a digestive juice called BILE. BILE is a thick yellow substance stored in the gallbladder. Functions: digest fats

The Liver Store Glycogen- ​most carbohydrates are broken down by the digestive system into the simplest form called GLUCOSE (main source of energy)/ glucose stored in the liver is commonly called GLYCOGEN
