1. THE CIRCULATION

The circulatory system is the responsable to port the blood to all of the body.Is made up for the heart and blood vessels. The funcion of heart boost the blood to the blood vessels.

The blood

The blood is a liquid red, on circule in the interior of blood vessels when recorr all the organism. The our body have aproximally five liters of blood.Some of this functions are transport substances to all organism and protect the body of malalties

The composition of blood:

The blood is made up for a liquid appointed plasm and cells of blood when sure in the plasm.

The plasm is a liquid yellow formed basically of water. Transport nutritives substances and residuals substances
The blood cells are:

The red blood cells have form of cd and are red. Transport oxygen and carbon dioxe.

Whyte blood cells. Have irregular form and semi transparents. They combat the infeccions made up the organisms how influenza.

THE DIGESTION



This is the proces of digestion

THE PARTS OF DIGESTION

How digest food?

Digestion includes the mixture of food, its passage through the digestive tract and chemical decomposition of large molecules into smaller molecules. It begins in the mouth, where masticamos and eat, and ends in the small intestine. The chemical process varies slightly depending on the type of food.

The large and hollow organs of the digestive system have muscles that allow its walls move.
The first major movement occurs when muscle eat foods or liquids. Although this part of the process is voluntary, begins as soon as it becomes involuntary happens to be under the control of nervios.Despues, passes through the intestines (first by the great and then by paqueño) and within a few hours be accepted

1.1 THE TISSUES




















TISSUES: A tissue is a mass of cells each of which performs a similar function. The four types of tissue are epithelial, connective, muscular, and nervous.



ORGANS:An organ is a structure composed of two or more tissues which combine to perform a specific function(s). Examples of organs are the stomach, heart, lungs, skin, etc.




AN ORGAN SISTEM:An organ system is composed of two or more organs which combine to perform a specific function(s). Examples of organs systems are the cardiovascular system, muscular system, skeletal system, nervous system, et







TISSUES IN ANIMALS : TYPES OF TISSUES

Epithelial : Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

CONNECTIVE TISSUES: Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage.

MUSCLE TISSUES:Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

NERVOUS TISSUES:
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning. To do all these things, cells in nervous tissue need to be able to communicate with each other by way of electrical nerve impulses.
