BULIMIA AND ANOREXIA

Anorexia

This disease manifests itself in the rejection of food. People who suffer from it have a distorted image of their own body: they imagine that they look fat, despite being thin or even extremely thin.

They live with an intense fear of gaining weight, eat little food, count calories, are hyperactive, are socially isolated and often use laxatives.

Consequences: weight loss, fatigue, tiredness, dizziness, excessive sensitivity to cold, hair loss, dry skin, heart problems.

Bulimia

People with bulimia are afraid of fat becoming, however, they secretly eat compulsively and make themselves vomit after eating. They avoid social gatherings and may use weight loss medications.

Consequences: thickening of the neck glands (thyroid and parathyroid), small vascular breaks in the cheeks, fatigue, muscle aches, throat irritation, infections in the gums and loss of enamel on the teeth.

CIRCULATORY SYSTEM

CIRCULATORY SYSTEM

In all living organisms, nutrients and waste substances are transported through the body thanks to the circulatory system. In vertebrates, blood moves through the entire body via blood vessels, to distribute oxygen and nutrients to the cells needed to perform our vital functions.
In the case of plants, circulation of water and minerals is conducted by ducts called the xylem and circulation of food (sugar) is transported by the ducts called the phloem.

Blood vessels
Blood vessels are tubes through which blood circulates. They are classified in arteries (carrying blood with oxygen), veins (carrying blood with carbon dioxide) and capillaries (delivering oxygen and nutrients to the cells).
The blood 
This is a tissue in a liquid state. It is formed by plasma (made up of water and nutrients) and blood cells (composed of red blood cells, white blood cells and platelets).

Blood circulation 
It has two phases: general or greater circulation, and pulmonary or lesser circulation. The first is the journey that the blood makes throughout the body. The second is the journey of blood between the heart and the lungs.

Circulation in human beings 
Human beings have a circulatory system that consists of the heart, blood vessels and blood. Its function is to transport to all the cells the oxygen and nutrients the body needs, as well as to circulate and remove wastes.

The heart 
This is a muscular, inverted cone-shaped organ, the size of a fist, located in the center of the chest, between the lungs. It functions as a pump that pushes blood to all parts of the body.
It is divided into four cavities: two upper cavities (atriums) where the blood arrives and two lower cavities (ventricles) where the blood passes before being pumped all around the body in arteries.

Pulmonary circulation 

All the blood the veins, loaded with CO2, enters the right atrium, passes to the right ventricle and reaches the lungs through the pulmonary artery. Then, blood is oxygenated through the pulmonary veins, comes out of the lungs, goes to the left atrium into the left ventricle and out through the aorta (the main artery of the body).

Systemic circulation 

The oxygen-rich blood that leaves the heart through the aorta is pumped to all the arteries of the body giving nutrients received from the digestive system and oxygen absorbed by the lungs to all the body’s organs.

Respiratory System

PROCESS OF  RESPIRATORY SYSTEM

Nose

The nose have two nostrils. The nostrils is a cavity that serves as filter when the air enters out bodies. Have you noticed how hairy our nostrils are? These hairs actually catch dirt and dust particles and clean the air we breathe! When we blow our noses, the snot that comes out is made up of this mucus and the dirt particles.

Mouth

Most of the air we breathe comes through our nose. But, we can also breathe through our mouths to get more air!

Pharynx

The pharynx, or throat, is part of the tube that air will go down to enter our lungs.

Larynx

The larynx is a tube where the vocal cords are locates. Its vibration with the passes of air produce the voice.

Trachea

The windpipe is a long tube that goes down our neck to the lungs. The windpipe’s lining makes mucus, which traps dust and other dirt particles. this mucus towards our throat, where we swallow and digest it.

Bronchi

There are two bronchi. The inner wall has cilia and mocus to filter the air and trap the particles that have been breathed in.

Bronchioles

The bronchioles are like tree-structure. They absorbe air in each lung.

Lungs

Two spongy organs in our chest. Lungs have a lot of little air sacs called alveoli. Tiny blood capillaries run through alveoli. When air reaches the alveoli, it passes into the bloodstream. It is then carried around our entire bodies.

VERTEBRATES AND INVERTEBRATES

Vertebrates

Animals are classified into two groups: vertebrates and invertebrates. Vertebrates are animals with backbones. The species of vertebrates include birds, mammals, fish, amphibians, and reptiles.

Characteristics of Vertebrates

The most special characteristic of vertebrate animals is having vertebrae. Vertebrae are the small bones in your back that make up your spine. The vertebrae connect together by joints to form the backbone.

The backbone does more than help connect our arms to our feet. In fact, it helps it protects our spinal cord. It is very important to protect the spinal cord, because it is what connects our brain to the rest of our body. The spinal cord and brain work together to form our central nervous system.

Invertebrates

Have you ever wondered if all animals on Earth have the same body structures? For example, do insects such as caterpillars and bees have backbones like mammals.

Characteristics of Invertebrates

An animal that does not have a backbone or a vertebral column is an invertebrate. In the animal kingdom, they are actually the largest group. They make up 97% of all animals on the planet.
