The Knowledge Of Anatomy And Physiology Essay

The function of the connective tissue is to support, bind, cover, protect and give structure to the body.

* Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively charged.

Homeostasis is what allows our internal system to maintain at a constant condition. In order to maintain equilibrium the body must communicate using the control system. It is essential that the body monitors its conditions whether that be blood pressure, thirst sensation or body temperature (this is either gained or lost). Negative feedback is most important and comes first, this allows for the body to correct itself and get back to a set point when it is off track. There are three components that link with this feedback. A sensor (receptor) sends signals to the control center that something is unusual, the control center compares the many values of our normal body range and decides

A sodium ion (Na+) occurs when a sodium atom loses an electron and gains a positive charge

1. Predict: Positively charged protons in the nucleus of an atom are attracted to negatively charged electrons.

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

As Jim’s muscles are at maximum demand, his mitochondria are unable to produce the needed ATP through aerobic respiration because oxygen is unable to diffuse fast enough into his muscle fibers. At this time anaerobic

Alpha: is a helium nucleus and is made up of 2 protons and neutron and has a positive charge. When it is ionizing it can knock out the electrons because of the collisions.

One of these properties is called an electrical charge. Protons have a "positive" (+) charge, electrons have a "negative" (-) charge, and neutrons have no charge, they are neutral.

3. Electrons are small and are negatively charged (-) with a mass of almost 0 amu..

In which layer of the Earth's atmosphere do most of the charged particles of the ionosphere coexist with neutral (uncharged) atoms and molecules?

Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used

When pathogens enter our body the Leukocytes and Antibodies destroy the pathogen and remember the pathogen so it is aware and can attack immediately if the presence of the pathogen is seen again. A neutrophil is what protects us against bacteria while antibodies protect against pathogens.

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.

My hand was sprinting across the page with charcoal in palm, and the finish line of my sketch was in sight. The image of a model’s face was quickly appearing, and the proportions of her eyes-to-nose and ear-to-mouth were just right. Proportions of the human face were something I learned in art class, whereas the details in her eyes were something I learned in anatomy class.
