Epithelial tissue

Imagem
Feature:  lack of space betware, excellent capacity cell renewal projects the body against the entry of microorganism ( viruses, bacteria, protozoa), chemicals and physical aggressions ( cuts, blow, scratches ). Epithelial tissue is found on the outside of the body (cornea epidermis) and on the inner surface of hollow organs sch as the sdomach, ear, lung, mouth, uterus, nose, bladder. Functions:  responsible for the formation of certain glands( liver, salivary, glands and pancreas).  Reference- SABOTTA, Johannes. Anatomia Humana, Saude Ed. Guanabara Koogan . 2013. Pag 362  

The cardiovascular and lympatic system

Imagem
The cardiovascular and lympatic system are generaly known , as a circulatory system, because os its interrelated functions, in the circulation of fluids (blood and lymph) througout the body . Formed by heart, blood vessels and lymphatic vessels.  Cardiovascular system -   composed  of the heart and the set of blood and pushes through the vessels,blood vessels carry the blood, carrying oxygen ,nutrients and hormones to the cells, removing carbon dioxide and other wastes. Lympathic system -   formed by a network of lymphatic vessels that drain excess fluid (lymph) from extracelular tissues to the blood vessels.   Reference- ZIERI.Rodrigo; Anatomia Humana. São Paulo.  Ed. Person Education do Brasil .2014 . Pag 91-106

The connective tissue

Imagem
The connective tissue is characterized by presenting several types of cells. It has the function of forming the base of the skeleton, storing and transporting nutrients, encircling all the blood and nervous vessels of the body and leading the body's fight against infections. Connective tissue can be classified into connective tissue proper (loose and dense), connective tissue of special properties (adipose, elastic, mucosal, reticular or hematopoietic) and connective tissue of support (bone and cartilage).

The nervous system

Imagem
The nervous system is responsible for receiving and processing information. It is divided into two parts: central and peripheral nervous system. The central nervous system consists of the brain and spinal cord, and the peripheral nervous system, which consists of a set of nerves, nerve ganglia and terminal organs. The function of the peripheral nervous system is to connect the central nervous system with the other parts of the body.

Urinary system

Imagem
The urinary system comprises the organs responsible for the formation of urine and the kidneys associated with the elimination of urine. The Rim is an even, abdominal organ located posterior to the parental peritoneum. The kidneys are responsible for the production of urine and also function as endocrine glands because they produce the renin that controls the secretion of aldosterone. Organic activities result in the breakdown of lipid and carbohydrate proteins, accompanied by release of energy and the form of products that must be eliminated to the outside environment. Urine is one of the body's excretion vehicles. Reference: DANGELO, Jose; FATTINI, Carlos. ANATOMIA HUMANA Sistêmica e Segmentar : Sistema urinário: Atheneu, 2007.

The vagina is a 6 to 10 centimeter long, elastic wall channel that connects the cervix of the uterus to the external genitalia. The uterus joins the ...

Nervous system

Imagem
The nervous system and the part of the organism that transmits signals between the different parts of the organism and coordinates its voluntary and involuntary actions, it arises in the neuronal phase developing through the neural, divided in brainstem, encephalus, spinal cord, cerebellum, brain and spinal cord.   Referencia: GARCIA, sonia.

The Male Reproductive system

Imagem
The Male Reproductive system consists of: Testicles : They are the sperm producing organs, and that from puberty, also produce a hormone, testosterone, responsible for the appearance of secondary sexual characters. Epididymis : There spermatozoa are stored until the time of ejaculation. Deferent Duct : it is the continuation of the tail of the epididymis. Originates from the sperm reservoir and leads them to the ejaculatory duct. Ejaculatory Duode:  Of the conductive spermatozoa, is the one of smaller size and smaller caliber. It comes out in the prostatic part of the urethra, next to a protrusion called the seminal colliculus. Urethra : It is a common channel for urination and ejaculation. Prostate : This is where the prostatic secretion joins the secretion of the seminal vesicles to constitute the volume of the seminal fluid. Penis : Male copulation organ, in addition to serving as channel for ejaculation, it is through this organ that the urine is also expel...

Muscle tissue

Imagem
Muscle tissue cells are called muscle fibers and have the ability to contract and stretch allowing various body movements. Muscle tissue can be of three types: Smooth:  involuntary and not fluted, it can be found on the walls of internal organs Skeletal striatum:  Voluntary, striatum attaches to bones Striated cardiac : Involuntary striated, is found in the heart.
