Circulatory System

Our circulatory system circulates blood in two parts: 1. From the heart to all parts of our body :  the blood contains of oxygen, nutrition and water that produce energy 2.  From all parts of our body back to outer heart: the blood contains waste materials and carbon  dioxide Pulse is a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck. Pulse rate /Heart rate is The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. Factors that affect our heart rate are age, health and activity: Age: body heart rate : 120 times per minute, adult : 60-90 times per minute elderly: 60-80 per minute. Health : the heart rate of a  healthy person  usually slower than a that of a sick person. Activity : when we exercise our heart rate increases.

Our heart is the vital organ that pumps our blood all the time, to all parts of our body

Blood Vessels are tubes that carry blood to all parts of our body. Some blood vessels carry blood from our heart to all parts of our body. Other blood vessels carry blood from other parts of our body to our heart.

Our blood carries oxygen, nutrient  and water to all part of our body It also carries carbon dioxide and waste substances that are produced by our cells away from different parts of our body

Circulatory System Diseases

Common diseases of the circulatory system are: 1. Arteriosclerosis,  in which the fatty deposits in the arteries causes the walls to stiffen and thicken the walls. The causes are a buildup of fat, cholesterol and other material in the artery walls. This can restrict blood flow or in severe cases stop it all together, resulting in a heart attack or stroke. 2. Stroke /Heart attack  involves blockage of the blood vessels to the brain and is another major condition of the circulatory system “Risk factors include smoking, diabetes and high cholesterol,”  3. Hypertension   commonly called high blood pressure causes the heart to work harder and can lead to such complications as a heart attack, a stroke, or kidney failure. 4. Arteriosclerosis occurs when the aorta is damaged and starts to bulge or eventually tear, which can cause severe internal bleeding. This weakness can be present at birth or the result of atherosclerosis, obesity, high blood. Healthy diet is important for the proper functioning of our circulatory system. 5. Damage in the heart or blood vessel  destroys the heart valves that control the direction of blood flows through heart. 6. Congenital heart disorder as a result incomplete of the heart or blood vessel before birth. Surgery is needed to correct such disorders. Blood diseases : 1. Anemia is a disease of blood when the amount of the blood cells in our body is low. Causes the body lack of oxygen. 2. Leukemia also known as blood cancer  or bone marrow cancer this disease occurs when the white blood cells multiply abnormally

ANIMAL RESPIRATORY SYSTEM

1.  Breathe through Lungs

Manatee

Manatee

Dolphin

Seal

Sea lion

Whale

Rabbit

Reptilian that breath with lungs: Snake, tortoise and lizard

The class Aves  includes all the birds.

Dogs, Cats , bears, human  are members of the vertebrate class 

Mammalian Mother and her baby

2.  BREATHING through skin

Salamander

Earth Worm

Toad

Frog

A nudibranch, a marine mollusk that breathes through its skin and primitive gills

Red-backed, they breath through their skin (having no lungs), amphibians use their skin as a respiratory organ. Cutaneous respiration is a form of respiration in which gas exchange occurs across the skin 

                                  3.  BREATHING THROUGH gills

Starfish

Clams

Frawn

Jelly Fish

Sea Worm

All kind of fish

            4.  BREATHING THROUGH breathing tube  or  air tubes

Grasshopper

Ant

Praying Mantis

Butterfly

Bee

Ant, Insects take in Oxygen and expel Carbon Dioxide using a series of internal air tubes, the tracheae.
