The integumentary system- This system is overlaying the outer body. • Anatomical location- The integumentary system is superior or external to the body. The organs that make up this system are the skin, glands, nails, hair, and sense receptors. In addition, the skeletal frame is superficial to the cutaneous membrane in the human body. • Key Anatomical features- The skin, nails, hair, and glands.
Apart from this, the body temperature is regulated and the moisture content in the body is also regulated to a certain extent by the skin. The skin is made up of three layers and all the layers have a key role in acting as the defense. The outermost layer which is the epidermis is an actively regenerating layer. This layer keeps on growing and differentiating to maintain the pH and moisture content. The epidermis does not work alone in keeping the skin healthy.
HOW THE SKIN PROTECTS THE BODY The skin plays a major part in regulating human body temperature and protecting the body. It consists of two layers: the outer epidermis and the inner epidermis. Beneath these layer is the adipose tissue, which contains fat-rich cells. PROTECTION:The outermost layers of the skin are dead cells, this protects the living cells below from Infection, Mechanical, Dehydration. The epidermis protects the body from damage and acts as barrier to prevent the loss of water and the entry of pathogens.The epidermis is the outer layer of the skin.
The operculum is corneous (Alderson 2015). Four main structures of Pomacea urceus can be observed: the foot, visceral mass, mantle and the face. The foot is the soft muscular part that is used to move about. Its visceral mass houses the digestive apparatus and the pericardial cavity. The mantle has the function of secreting the shell and the face consist of two long tentacles, with the eyes being at its base.
Venomous frogs are fortified to live in forest environments where they could be easily made into a meal at any second. The small amphibians use a series of spikes on their head to deliver blows to would-be attackers, thwarting off all potential threats to their life. According to Brody, the venomous frogs have very few natural predators in the wild, “We don’t know of any animal that successfully feasts on these frogs. Nothing can get past the head spines.” Will frogs ever be viewed the same way
Vertebrates are known to be animals with backbones. Tooth reduction is one of the major evolutionary trends that developed among major vertebrate groups that allowed for the transition from aquatic to terrestrial life. Evolution of limbs and being able to breath air are other evolutionary trends that took placeThese trends include improved respiration and protective and insulating body coverings. More over the transition from water to land also included changing to more efficient reproductive methods like having a placenta for some animals or egg layers for other animals. Lastly, the morphology of organisms evolved such that for land they would have paired, muscular appendages used for crawling and
biopsy, cosmetic surgery) -Health practices related to integumentary system (ex. hygiene, sun protection). i.Nutritional-metabolic pattern: indicates changes in the skin, hair, nails and mucous membranes and whether they are related to dietary changes. ii.Elimination pattern-ask patient about conditions of the skin such as dehydration, edema, and pruritus iii.Activity-Exercise pattern- environmental hazards (ex. carcinogens, allergens) iv.Sleep-Rest pattern- disturbances in sleep caused by a skin condition v.Cognitive-Perceptual pattern- patient 's perception of the sensations of heat, cold, pain, and touch.
We all know that since ancient times animals were very important for various reasons. They were reared mainly for food, whilst others were kept as pets. Animals affected every area of everyday life, from the economy to religious beliefs and rituals. Animals in mythology are usually tied in with fertility and vitality, because they are living, moving, and growing. They also provide vitality and continued life for the tribes through their meat, skins, and bones.
Centipedes have a system of breathing, they breath with tubes ranges from the spiracles throughout the body. They have the extrudable external gills between most of their legs which enlarge breathing surface of the animal like in other animals living in water. Centipedes appear smooth and shiny. Centipedes have hairs all over the body which are sensitive to touch and vibrations, this hair helps them to sense their environments. Reproduction and life cycle of the
The Ekurhuleni Metropolitan Municipality alone has 1644 different species, 255 of birds’ species, 14 amphibians and 41 species of reptiles (Ekurhuleni Metropolitan Municipality, 2004). On an international scale, scientists have noticed a decline in the population of amphibians and some to the point of extinction. Amphibians are mostly affected by habitat destruction and pollution due to human activities (Primack, 1998). Amphibians are sensitive to global environmental factors like climate changes, increased ultraviolet radiation, habitat fragmentation, chemical pollution and acid rain. Chemical pollution easily penetrates in the amphibians’ epidermis and a slight change in the water pH can destroy eggs and tadpoles (Primack, 1998).
