CIRCULATORY SYSTEM

The circulatory system

The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids andelektrobites, oxygen,carbon dioxide,ormones and bloodcells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis..The circulatory system of the blood is seen as having two components, a systemic circulation and a pulmonary circulation.[4]

While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to be returned to the blood.[5] The more primitive, diploblastic

DIGESTIVE SYSTEM

The digestive system is a set of organs that transform the food that we eat into the necessary nutrients and vitamines that we need to live and grow.

PARTS OF THE DIGESTIVE SYSTEM

Mouth: Is in charged of crushing the food that we eat and then mix it with saliva. 

Esophagus: Is a conduit that transport the food from the mouth to the stomach.

Stomach: Produces gastric juices and it mixes them wi

th the foodd.

Liver: It helps to break down food thanks to a liquid called bile. 

Small Intestine: Is in charged of absorbing the nutrients from the food mixed with bile and passing them into the blood.

Large Intestine: It transforms the undigested food into faeces. 

Rectum: Finally, the faeces leave the body through the anus. 

HOW THE DIGESTIVE SYSTEM WORKS?

In order to digest the food that we eat the digestive system has three different steps: digestion, absorption and elimination.

Digestion stage: The mouth, esophagus and stomach all help our body digest the food we eat.

Absorption stage: The small intestine absorbs, the nutrients from the food.From the small intestine, the nutrients go into  your blood.

Elimination stage: The large intestine and rectum transform the undigested solids into faeces.

ILLNESSES

Heartburn: It is a painful burning feeling just below or behind the breastbone. Most of the time, it comes from the esophagus. The pain ofthen rises in your chest from your stomach. It may also spread to your neck or throat.

Constipation: In infants and children occurs when they have hard stools or have problems passing stools. A child may have pain while passing stools or may be unable to have a bowel movement after straining or pushing.

Fun Fact: the small intestine of an a adult can reach a lenght of 7 meters.

The respiratory system

THE RESPIRATORY SYSTEM

Why do we have to breathe?

The respiratory system is essential to live. We breathe because our body needs energy to run jump, study, talk, etc. The cells need oxygen in order to create energy. Oxygen reaches the cells with the respiratory system and breathing. Without oxygen, the cells would die and we would also die.

The main parts are:

• Nose and Nasal Cavity
• Mouth
• Pharynx
• Larynx
• Trachea
• Bronchi and bronchioles
• Lungs
• Muscle of respiration

How the respiratory system works?

Inhale

We breathe through the nose or through the mouth. The air traverses the trachea reaching the lungs. When we breathe we use the diaphragm making our lungs fill with air.

Alveoli

They are small sacks of air. They pass oxygen to the red blood cells.

Exhale

The alveoli not only transmit oxygen to our blood, they also help eliminate carbon dioxide in the blood.

Illnesses that can affect to the respirator system?

The most ommon problems of the respiratory system are:

• Asthma
• Chronic Obstructive Pulmonary Disease
• Chonic Bronchitis
• Emphysema
• Cystic fibrosis
• Pneumonia

How does smoking affect your lungs?

Smoking is bad for the lungs. The cigarette contains many chemicals that harm your respiratory system. The smoker`s people have at an increased risk for smoker’s cough, bronchitis, and infectious diseases such as pneumonia.

Cancer isn’t the only health problem smoking can cause. Inhaling tobacco also impairs blood circulation. This can increase your likelihood of:

• a heart attack
• a stroke
• coronary artery disease
• damaged blood vessels

Relationship

The circulatory system, the respiratory system and the excretory system work together all the time so that our body can move. The circulatory and respiratory system causes blood and oxygen to travel throughout our body.

Circulatory system. The main relationship with the respiratory system is thanks to the heart. The heart pumps blood with oxygen throughout the body.

Excretory system. when the respiratory system picks up oxygen from the outside through the nose or mouth, the excretory system is in charge of eliminating the waste products or gases that we do not need.

Respiratory System

HOW DOES IT WORK:

The respiratory system is a series of organs responsible for taking oxigen and expelling carbon dioxide.
the primary organ for respiratory system are the lungs wich carry aut this exchange of gases as we breathe
PARTS:

ILLNESES:
Astham:is a chronic disease of the lungs that inflames and narrows the airways
luns cancer: pruduce cough with blood(saliva or phlem) of the color  oxidized metal
pain in the chest that often gets worse when you breathe deeply cough  or laugh
Acutes bronchitis : is very common and often occurs from could or other respiratory infection


RELATIONSHIP:
the points with respiratory system your blood would beustess.
The circulatory sistem and respiratory sistem work together to circulate blood and oxigen
troughtthe body,airmoves in and out the lunga trougt the tarchea bronchi and bronchiles.

RESPIRATORY SYSTEM

Parts:

1. Mouth and nose: air enters to the body through the mouse and nose.
2. Vocal cord: As nair passes our vocal cords, they vibrate and anable us to speak.
3. Trachea: This long rigid tuve connects our mouth and nose to our two bronchi. Air travels down the trachea into the bronchi.
4. Lungs: these two large bags are connected to the bronchi. The bronchi branch into millions of smaller tubes, or branchioles, here in the lungs.
5. Bronchi: these two smaller tubes connect the trachea to the lungs.
6. Bronchioles: these are small tubes inside the lungs. At the end of each bronchiole, there are tiny sacs called alveoli. The air we breathe in goes into these tiny sacs and then passes into blood vessels which surround the.

ILLNESSES:

1-Asthma

2-Bronchitis

3-Lung Cancer

4-Pneumonia

5-Tuberculosis

6-Sleep Apnea

FUNTIONS:

The functions of the respiratory system deliver air to the lungs. Oxygen in the blood and dioxide out.

Respirarion includes the follwoing processes:

External respiration is the process of gas Exchange between the atmosphere and the body tissues to make:

a.  The process of breathing (inhailing air and exhaling air).

b.  Gas transport, the process of distributing the oxygen throughout the body and collecting CO2 and returning it to the lunges.

 

RELATIONSHIP:

• Circulatory system: its connection with the respiratory system is that the last one takes oxygen through the mouth and nose and then it goes down the trachea into the lungs. Then the oxygen goes to the heart where it is sent out of the heart in blood to other parts of the body. The heart pumping out the oxygen is how the respiratory system and circulatory system are connected.

• Excretory system: its connection with the respiratory system is when the last one provides oxygen for the heart and it is sent out in blood to other parts of your body, there are also unwanted or used gases in the blood such as urea. As the blood passes through the excretory system it gets rid of unwanted gases. The oxygen in blood passing through the excretory system and excreting the unwanted gases is how the excretory system and the respiratory system are connectec.
