ENDOCRINE SYSTEMThe endocrine system controls your mood, sleep, hunger, digestion, emotions, breathing rate and the rate our heart beats just to name a few.So how could one system have so much influence?

HORMONESWe are studying the Endocrine System First because this system is affects almost if not all processes our body participates in. It controls sleep, hunger, digestion, emotions, breathing, the rate of our heart beats, the things we enjoy the list goes on and on. Many times this system is put towards the end and little if any time is spend talking about it. For this reason, we are looking at it first.8ENDOCRINE SYSTEMGlands are the major organs of the Endocrine system. HypothalamusThyroidPancreasovaries/testiesPituitary glandParathyroidThymusAdrenal Glands

ENDOCRINE SYSTEMThe functions of the Endocrine system are regulating your mood, growth and development, tissue function, and metabolism, as well as sexual function and reproductive processes.

The integumentary system is composed of the skin nails 3. glandsFunction of skin:1. Provide protection 2. Regulate body temperature3. Sensory

Integumentary System

Skin has 3 layers:Epidermis nails and hairDermis blood vessels, nerves, glands, smooth muscle, and hairHypodermis fat

EpidermisEpidermisEpidermis

1st Layer Epidermis Contains KERATIN protein that forms hair, nails, calluses Contains MELANIN gives skin colorDERMIS

DERMISDERMIS

2ND Layer Dermis Contains blood vessels, nerves, glands, smooth muscle, and hair Contains 2 types of glands:1. Sweat produces sweat2. Sebaceous produces oil

Hypodermis or SubcutaneousContains layer of fat and connective tissue; provides insulation

EpidermisDermisSubcutaneousFatDegrees of burnsFirst Degree Burn Only the superficial epidermis is burned and is painful, but is not blistered.

Second Degree Burn - Deeper layers of epidermis are effected, could have inflammation,blisters, and the burned skin is often painful.

Degrees of burns

Caused by hot glueThird Degree Burn- The entire epidermis is charred orburned away,and the burn may extend into the dermis. Often such a burn is not painful at first because the sensory receptors in the dermis may have been destroyed.

Degrees of burns

Extensive third degree burn- Potentially life threatening because of loss of skin, without this natural barrier, skin is exposed to the environment and is susceptible to infection and dehydration.

Degrees of burns

Skin Graft - A skin graft is a surgical procedure in which a piece of skin is transplanted from one area to another. Often skin will be taken from unaffected areas on the injured person and used to cover a defect, often a burn. Taking the graft from the injured person makes rejection of the tissue unlikely.

The most common job of the smooth muscle is to squeeze.

Smooth muscle is involuntary, contains a single nucleus, and lacks striations.

Types of Muscle Pumps our blood Involuntary Contains striations and a single nucleus per cell.

Types of Muscle Attached to and moves your bones. Main job is for movement. Voluntary, multi-nucleate, & striated
